Issei Hyoudou (兵ひょう藤どう 一誠いっせい, Hyōdō Issei) is the main male protagonist of High School DxD. He is a third-year high school student at Kuoh Academy in Class 3-B and a member of the school's "Perverted Trio", a trio of the most perverted men in the entire student body. He likes the other girls but love’s Rias Issei is the Pawn of Rias Gremory's Peerage and a member of the Occult Research Club. After the Evil Dragon War, he was promoted to the rank of a High-Class Devil, becoming the King of his own independent peerage, and is one step closer to fulfilling his dream of having a harem and becoming a "Harem King". Due to his possession of the Longinus; the Boosted Gear, which hosts the Welsh Dragon, Ddraig, Issei is the direct rival of Vali Lucifer, who is the host of the Vanishing Dragon; Albion, who is Ddraig's archrival. Issei is a high school student of average height with short spiky brown hair, with two short locks of hair behind his head, and light brown eyes. Following his training with Tannin, he gained a more muscular and toned build. While he has worn various outfits throughout the series, his most commonly worn outfit is the Kuoh Academy boys' school uniform, which consists of a blazer (more commonly black, although in other media is shown with a tinge of purple or grey, with white accents) over a white, long-sleeved dress shirt with black highlights with a black ribbon on the collar, matching black pants, and brown dress shoes. However, Issei's uniform differs in the fact that he wears a red T-shirt underneath his open dress shirt and blazer, and wears blue and white sneakers in place of dress shoes. Even by his own admittance Issei is an unintelligent and straightforward individual, with his tremendously perverted and lascivious nature being the greatest characteristic of his personality. Issei easily indulges in lewd fantasies, being obsessed with female breasts and a desire for a harem, traits he openly admits and makes no effort to hide, a characteristic that he is, in fact, proud of. This has caused him to be instantly labeled as a pervert among the girls of Kuoh Academy and has gained him notoriety for being one of the members of Kuoh Academy's Perverted Trio. Despite his pervertedness, Issei is courageous, selfless and unwaveringly determined to protect those who are important to him, despite almost dying by the hands of his opponents. Age 18 Dragon Shot (魔力弾ドラゴンショット, Doragon Shotto): One of Issei's signature moves, where he releases a beam of concentrated Demonic Power. It is often used in tandem with Boosted Gear to increase its destructive potential, once destroying a mountain. When enhanced by the Boosted Gear Scale Mail, Issei's Dragon Shot became powerful enough to casually "erase" a mountain, and when enraged it overwhelmed a full powered demonic power blast by Diodora, a High Class Devil enhanced by Ophis's snake. Issei can go into his limit break mode upgrading his strength with a crimson like dragon armor. Boosted Gear (赤龍帝の籠手ブーステッド･ギア, Būsuteddo Gia): Issei's Sacred Gear and main weapon, among all the original 13 Longinus, which holds the Welsh Dragon, Ddraig's soul, making it a Mid-Tier Longinus. A left-handed red gauntlet that doubles his powers every 10 seconds until he reach his limit, holding the potential to kill god if mastered. He later gained the ability to Transfer the multiplied power into a person or item, even parts like his eyes for enhanced vision. Issei later awakened Penetrate, letting him bypass all defenses (save the targets baseline physical durability) like Rizevim's Sacred Gear Canceler or barriers. He later developed a technique of applying Penetrate to his eyes to see through women's clothing. Dragon Aura: Due to possessing Boosted Gear, then having his left arm turned into a dragon, Issei has a small amount of dragon aura. Training with Tannin increased it, to the point of dealing minimal damage while using Boosted Gear. After gaining a new body, made from a combination of Great Red's flesh and Ophis' power, it became more natural, described as being dominant. Pailingual (乳語翻訳パイリンガル, Pairingaru): Issei's third signature move, which allows him to "talk" to women's breasts after creating a "space". As such, it is a useful move as it allows him to learn his opponents' plans by asking their breasts, however, complaints from females from other peerages caused Rias to ban it in Rating Games. Dress Break (洋服崩壊ドレス・ブレイク, Doresu Bureiku): Issei's second signature move, which he mainly uses against women. As its name suggests, this move allows him to "strip" woman by first coming into contact with them, concentrating his demonic power, then snapping his fingers to activate one of two effects. He can fly,has immense mobility,Speed,Strength and durability, and a expert close combatant and sword fighter.

Her hair also has loose bangs covering her forehead and side bangs framing her face. Rias' height is 172 cm. (5 feet 8 inches), making her one of the tallest female characters of the series.

Rias also tends to wear seductive lingerie and thongs, especially when she has a desire to sleep with Issei. On some rare occasions, Rias wears glasses when she's deep in thought, as she feels they make her mind work better despite having perfect eyesight. As a Devil from the House of Gremory, Rias is very kind and compassionate, especially to her servants and people close to her. She gets angry and violent whenever people insult her or her peerage, showing a fiery side to her. This also plays into the fact that she dislikes cruelty towards people Power of Destruction (滅びの力, Horobi no Chikara): A unique demonic power, which allows her to erase nearly anything, such as matter, energy and even immaterial things such as souls. She would originally often release massive blasts to engulf and erase her targets, but Rias has improved her control over her Power of Destruction to the point of being able to compress it into softball-sized bullets and release them in quantities Kiba compared to a machine gun, which he noted that those without enough power would vanish from one of them. Extinguished Star (消滅の魔星イクスティングイッシュ・スター, Ikusutinguisshu Sutā): Rias' Ultimate One-Hit Kill Technique, developed from both her own training and the influence of draining Issei's dragon power on her demonic power. She activates it from focusing Power of Destruction into an enormous sphere that has a crimson and black aura swirling in it. Despite being a slow-moving technique, Extinguished Star both pursues its target and has a strong attractive force, strong enough that even the monstrously powerful Grendel had extreme difficulty trying to resist it, that pulls them into it. Its destructive power has been said to surpass the Rating Game's retiring system. Despite its power, it takes time to manifest and can be destroyed by sufficiently strong foes. Castling: Due to being the King of her own peerage, Rias has the ability to use Castling, which allows her to swap locations with one of her Rooks. She first used it during Nilrem's attack on Kuoh Academy, swapping places with one of her unused Rook pieces. Healing: Rias is capable of healing others using her demonic power,

Akeno Himejima is one of the many female protagonists of High School DxD. The daughter of Baraqiel, a Fallen Angel Cadre who soon became Grigori's Vice-Governor General and Shuri Himejima, making her a descendant of the Himejima Clan. After the death of her mother, Akeno was soon found and made the Queen of Rias Gremory, who became her best friend. Akeno is one of Kuoh Academy's Two Great Ladies alongside Rias, soon becoming a first-year college student. She is also one of Issei's fiancées. Akeno is a beautiful young woman with a voluptuous figure, very long black hair and violet eyes. Her hair is usually tied in a very long ponytail, reaching all the way down to the floor with two strands sticking out from the top and sloping backward, with an orange ribbon keeping it in place. Like most of the girls at Kuoh Academy, she wears the customary Kuoh Academy girls' school uniform, along with black calf-length socks. As revealed in the visual book with her data her body measurements are [B102-W60-H89 cm] [B40-W24-H35 in]. Her body weight is [54 kg] [119 lbs] while her height is 168 cm (5 feet 6 inches). In the anime, during battles, she often transforms her clothes into a traditional miko attire, consisting of a white haori with red accents, a red hakama, and a pair of zōri with white tabi. After Akeno has revealed her Fallen Angel side in front of Issei, she has one Devil wing and one Fallen Angel wing. As the series progressed and she came to terms with her fallen angel powers, her wings increased to six, at first, because of the aid of Azazel's bracelets, then eight, resembling a High-Tier Fallen Angel. Personality Akeno is first seen to be a very elegant and gentle woman with refined lady etiquette, embodying the principals of the ideal Japanese woman: "Yamato Nadeshiko". However, underneath her calm, noble and dignified atmosphere, Akeno is shown to be highly sadistic in battle and doesn't show any mercy or remorse towards the enemies she slays, casually keeping up her smiling elegant persona over an enemy's death and showing an expression of pleasure and lust upon delivering them pain. Despite her sadism, Akeno is very kind, acknowledged by Rias and Issei. Before meeting Rias, Akeno would help people by purifying evil spirits for a living. As a result of seeing her mother being killed in front of her eyes and her father being unable to save her, Akeno developed a hatred for Fallen Angels, including a sense of self-loathing towards her own Fallen Angel nature, for it was the reason her beloved mother was killed by the Himejima Clan, which lead her to sever ties with her father, going into exile before being saved by Rias after Akeno's maternal relatives nearly killed her. Due to this reason, she empathizes with those who have suffered under the hands of Fallen Angels like Issei and Asia, who were manipulated and killed by the Fallen Angel Raynare, and was worried that Issei would dislike her due to her Fallen Angel nature. However, she fell in love with him after he told her that he still liked her. With Issei's help, she was able to overcome the sadness of her mother's death and reconcile with her estranged father, renewing their familial bond. Due to Issei helping her and Baraqiel in their reconciliation, Akeno's love for him deepened considerably as she confessed her feelings for him. While Akeno originally had no interest in dating men due to her past, she began to take an interest in Issei, thinking of him as a cute junior and that interest intensified after seeing his determination in the Rating Game against Riser Phenex and his actions during Rias' engagement ceremony, where he defeated Riser Phenex. She has stated that Issei is the first boy she has ever felt such feelings for as she is shown to have a desire to further her relationship with him. She also loves to tease Issei and Rias, as she loves to make Rias irritated by flirting with Issei stemming from her playful sadistic side. Akeno has also stated that she has some masochism in her as well, as she is only masochistic towards Issei in contrast to her sadistic nature in battle. She is shown to be quite vulgar, flirting with Issei as such and doesn't care if Rias knows or saw her doing the act as she tried to have sex with him while also trying to help Issei further his relationship with Rias, but does care enough to not steal him away from her as she even helped Issei confess to Rias. After falling in love with him, she becomes very seductive and is obsessed with having an affair with Issei whenever she finds a chance, which is often interrupted by Rias and some others. She also has a emotionally weak side to her once she removes her mask of being an Onee-Sama, what is left is her true side of "depending" on a man Akeno is still innocent and emotional towards love and acts like a girl her age whenever she is on a date with Issei. However, this still does not stop her from being seductive and flirting with Issei. Despite being seen as calm and clear, Akeno does get jealous like the other girls and will fight for Issei. Elemental Demonic Power: Akeno excels in using natural elements such as ice, fire, and water, but she specializes in lightning. She is able to create thunder clouds using her demonic power, making lightning bolts rain down on her opponents. She could freeze Cerberus' flames in an instant and target ice spears at her opponents. Much like her Holy Lightning Dragon, Akeno can also form Asian Dragons out of fire and ice, sending them at her enemies. Lightning Manipulation: Akeno originally specialized in lightning demonic power alone before she began using her Holy Lightning ability, where she imbues it with the power of light.

Koneko Toujou, originally named Shirone, is one of the female protagonists of High School DxD. At first, she is a first-year student at Kuoh Academy, prior to becoming a second-year, and a member of the Occult Research Club. She is a Nekoshou, a rare species of Nekomata, and the younger sister of Kuroka, as well as Rias Gremory's first Rook. Age 15 Having become one of Issei's fiancées, then coming to terms with herself, her past, and making amends with Kuroka, Koneko started going by Shirone Toujou. Koneko is a petite girl with white hair and gold eyes. Her body measurements are [B67-W57-H73 cm] [B26-W22-H29 in]. Her weight is [31 kg] [68 lbs]. The front of her hair has two long bangs going past her shoulders and several loose bangs hanging over her forehead, while the back has a short bob cut. She also wears a black cat-shaped hair clip on both sides of her hair, one of which contained the data on artificially making new Super Devils. She usually wears the Kuoh Academy girls' school uniform, without the shoulder cape. Koneko's height is 138 cm (4 feet 6 inches), making her one of the shortest female characters of the series. In her Nekomata form, she grows a pair of white cat ears and a pair of matching white tails, and her pupils become more cat-like. In Volume 24, she gained three tails. In her "Shirone Mode" that she used for the first time in Volume 16, Koneko can make herself grow older, and her attire consists of a short white kimono and a light blue skirt. Her bust size grows significantly larger when in this mode, making her look more similar to her sister Kuroka. In the anime, during the Rating Game between Rias and Riser Phenex, she wore black fighter's gloves with pink cat pawprints on the upper palm. Personality Due to witnessing her sister supposedly losing control over her nekomata power and killing her master, Koneko became traumatized by the event, causing her to become withdrawn into herself and stripping her of most of her emotions. As a result, Koneko originally had a quiet and cold personality, rarely showing any feelings or emotions, even when she was speaking. It is noted that her serious personality is a result of receiving influence from Rias, and it is also antithetical to her sister's mischievous and outgoing personality. She was also the only one in the group who did not initially get along with Issei, often insulting and rebuking the latter for his perverted nature, although she reveals that she respects him for never giving up and considers him a hard worker. She shows the most concern for her comrades when they are in trouble, often lending her strength in fights. Koneko apparently has a problem with people calling her a midget (although the context of the phrase could be used to be called flat, as in bust size), as shown in her second battle against Freed Sellzen. This may stem from her insecurity about her own small body and bust size. Born as Shirone, Koneko is a young Nekomata who is part of a rare species among her kind, called the Nekoshou. She was born from the union between a human father and a Nekomata mother named Fujimai. Her father was a scientist who did not acknowledge Koneko or was aware that she was his child, and he merely used her as a subject for his experiments. Her parents eventually died in an experiment-related accident. However, her older sister Kuroka, omitted the truth and any other details about them from Koneko to protect her. Demonic Power: Koneko has all the powers and abilities common to Devils, including the power to cast spells. Senjutsu Master: Being a Nekoshou, Koneko is able to use Senjutsu, she is still training under her sister, Kuroka as well as Magari. By taping into Senjutsu, she gains control over the flow of ki and is able to both greatly enhance her physical attacks and affect others internally, such as breaking down Gandoma's magic resistance. Koneko can use Senjutsu to detect the presence of others. Touki (闘気, Fighting Spirit): Koneko can cover herself in an aura of ki, drastically increasing her strength, defense, and speed. She could soon cover herself in a tremendous touki, surpassing her sister in terms of strength. Healing: Through the usage of Senjutsu, Koneko can use ki to recover both a person's physical and mental health, in addition to their stamina. Through being in physical contact with the person she's healing and can be used to even recover a person's life-force, which was damaged through different means and did so continuously after Issei used Juggernaut Drive. Bouchujutsu (房中術, Bedroom Method): A more effective and faster healing technique in which Koneko directly shares her ki with a man to heal life-force to a greater extent, this is done by the act of having sex. Though Koneko has never performed this, she claims to be capable of doing so when offering it to Issei should he need it. Kasha (火車, Burning Chariot): Koneko can summon multiple large wheels that are covered in white flames that have the power of purification. Sealing: Koneko had learned a practical use of Senjutsu from Kuroka as a counter-measure against the Evil Dragons revived using Sephiroth Graal, in which she uses a jewel from Issei's armor to seal their souls inside it, as shown with Grendel who was later stored and guarded in Heaven. Presence Suppression: Koneko has demonstrated the ability to use senjutsu to suppress her presence and avoid detection.

Yuuto Kiba is one of the male protagonists of High School DxD. He is a third-year high school student at Kuoh Academy in Class 3B and the school's "pretty boy" who is adored by many female students and hated by other male students. He is Rias' Knight and the Vice-President of the Occult Research Club. Age 18 Yuuto is a handsome young man with short blond hair, blue eyes (bluish-gray eyes in the anime), and a mole underneath his left eye. He wears the Kuoh Academy boys' school uniform, which consists of a black blazer with white accents over a white, long-sleeved dress shirt with a black ribbon on the collar, matching black pants, and brown dress shoes. Yuuto is overall an upbeat person and cares deeply for his comrades. He's also a very polite and friendly individual, even considering Issei's initial dislike towards him. As a Knight, he has pride, chivalry, dignity, and honor befitting one, and is shown to enjoy fighting fellow swordsmen like Karlamine. Initially, he had a deep hatred towards the Holy Swords or their wielders. But the efforts of the Occult Research Club members during Volume 3, and the souls of his deceased friends, who died earlier being victims of the Holy Sword Project, helped him overcome his drive for vengeance, making him more accepting of the Holy Swords. Yuuto considers Issei to be his best friend, but also feels a sense of rivalry with him, wishing to one day fight him fair and square. At the same time, he also shows deep concern for his well-being, desiring to avenge Issei after his death in Volume 11 and only stopping himself due to promising to protect the girls of the Club in his stead. Demonic Power: Yuuto has all the powers and abilities common to Devils, including the ability to cast spells. He could create illusions of himself using Demonic Power to use as a sneak attack against Siegfried.[1] Holy Sword Wielder: After absorbing the Holy Element and gaining his Irregular Balance Breaker, Yuuto became able to wield Holy Swords, once even borrowing Xenovia's Durandal. Enhanced Strength: Despite not being his main focus, Kiba is much stronger than an average human, being able to wield a sword much larger than himself, although this dampened his speed. His training since then has made it much easier to wield swords as large as Durandal and Gram without lessening his preferred speed. Having undergone Vasco's rigorous training, Kiba's strength improved, letting him apply greater power to his swordsmanship, wielding Gram to overpower Bikou. Immense Speed: Due to his Knight Piece, Yuuto has superhuman speed, which he trained and developed further as the core of his fighting style. Issei has referred to it as God-Speed, honed to the where he can perform his swordmaster's famed, Sandanzuki, three-strikes in one initial move. Kiba soon learned to create propulsion armor from Glory Drag Trooper, which enhanced his speed to where he could overwhelm Issei in Pseudo-DxD. Enhanced Durability

Gasper Vladi is one of the male protagonists of High School DxD. He is a cross-dressing male Dhampir, a half-Vampire half-human but was turned into a Devil by Rias Gremory. He has the ability to stop time and is Rias' first Bishop. Age 15 Because his powers were uncontrollable prior to the series, he was sealed in the Academy by Rias and was not seen again until Volume 4 of the light novels. He is a second-year high school student at Kuoh Academy, alongside Koneko and Ravel. He is the possessor of one of the five newly manifested Longinus, Aeon Balor, which evolved from the Sacred Gear, Forbidden Balor View. Gasper is an effeminate-looking male with platinum blond hair and pinkish-violet eyes. His hair is styled in short bob cut with several small fringes over his forehead, and he has pointed ears. Kiba describes him as looking like a beautiful girl. Unlike the rest of the boys of Kuoh Academy who wear the boys' uniform, Gasper wears the Kuoh Academy girls' school uniform with thigh-high socks, creating a Zettai Ryōiki (Japanese for "absolute territory"). Personality Originally a coward and a shut-in with a very shy personality, Gasper likes to wear female clothing, claiming that girls' clothes are cute. He also has a penchant for boxes, carrying one with him all the time. When Issei tried to give Gasper confidence, the former gave Gasper a paper bag to put over the latter's face. However, Issei comments that whenever Gasper puts the paper bag on, the latter looks like a molester. As the series progresses, with Issei and the Gremory group's encouragement, Gasper begins to gain confidence and bravery. When necessary, Gasper has displayed the ability to force down his timid nature and speak up as a man. On more than one occasion, he has demonstrated extreme courage and loyalty, going so far as to be beaten to unconsciousness in defense of his weakened comrades. Demonic Power: Gasper has all the powers and abilities common to Devils, including the power to cast spells. Enhanced Magic Power: As a Bishop, more so one who consumed a Mutation Piece, he can strengthen his demonic and magical powers. Dhampir Physiology: Being a Dhampir as well as one with rare Vampire abilities, Gasper has the ability to control bats and transform into a flock of them, usually using them for reconnaissance. Thanks to his human half, Gasper is immune to general Vampire weaknesses, but still feels some discomfort from them. Daywalker: Due to being Dhampir, Gasper is also a Daywalker, allowing him to survive contact with sunlight. Blood Consumption: Gasper can absorb other people's powers by drinking their blood, as shown when he drank Issei's blood, using Issei's Dragon power to boost his own, while allowing him to control Forbidden Balor View. Darkness Manipulation: Gasper can also manipulate shadows and darkness, though he initially had difficulty in controlling them adequately. This has changed, being able to freely extend and control his shadows. Gasper has shown the ability to change the shape of his shadow to suit multiple purposes, such as tentacles that can bind his opponents seemingly of their own will. Immense Strengthorbidden Balor View (停止世界の邪眼フォービドウン・バロール・ビュー, Fōbidoun Barōru Byū): Gasper's Sacred Gear and main weapon, which lets him stop anything and anyone within his field of vision in time. In the beginning, he couldn't control it without his vampire powers because its power continued to grow as time passed. Because Balor's consciousness and powers were sealed in it through the Sephiroth Graal, it can create and control a deep darkness that consumes anything, including the Dimension Lost's mist. Gasper can also switch perception with others, such as Issei on two occasions, letting him freeze Shalba and see whatever he sees Through transforming into multiple bats, he can also extend its range. Gasper's Sacred Gear would eventually be recognized as one of the five new Longinus, and renamed Aeon Balor (時空を支配する邪眼王, Aiōn Barōru), also known as The Evil-Eyed King Who Dominates the Space and Time.

She also wore a silver cross necklace around her neck (she was later forced to remove it after becoming a Devil). Upon transferring to Kuoh Academy, she wears the Kuoh Academy girls' uniform, albeit with a black sweater vest over her dress shirt in place of the cape and corset which has become her current main attire. Personality Asia is extremely shy, innocent and fairly inexperienced in things like socializing. As a former nun, Asia is a devout Christian, despite being reincarnated as a Devil, Asia still believes in God and follows his teachings such as praying to him and reading the Bible, which would usually result in her getting severe headaches. Asia has a strong kindness, even when she was still a human, she harbored no hate towards Devils and treated everyone equally, regardless of what they were. Azazel noted that her unconditionally kindhearted nature forces her Sacred Gear to heal even enemies, as she is incapable of turning a blind eye to the suffering of others. Asia was also in deep shock when she learned from Kokabiel that the God of the Bible was killed during the Great War. While initially having difficulty adjusting to her new life as a Devil, she has stated that she has found more important things than her faith in God, those things being her new friends, comrades as well as Issei's parents and Issei himself. Asia is noted to be a very pure individual as people are drawn to her and that she is easily liked by others. Her charm and purity is such as that she was able to tame Rassei, a Sprite Dragon despite being a Devil as normally Sprite Dragons aren't tamable by Devils and are only tamable by those with pure hearts. Azazel noted that she had outstanding talent for taming dragons, as after receiving Ophis' blessing, she was able to form a contract with Fafnir, one of the Five Great Dragon Kings. After she managed to tame 4 mass-produced Evil Dragons, her name was spread in the world of Dragons due to the fact that only Evil Gods were able to tame Evil Dragons, as she became known as the Dragon Priestess (龍の巫女, Ryū no Miko) among Dragons. Demonic Power: As a Devil, Asia has all the common skills and powers of one, including the power to cast spells. Enhanced Magic Power: As a Bishop, Asia can strengthen her magic and demonic powers, which she normally applies onto her Twilight Healing.

Twilight Healing (聖母の微笑トワイライト・ヒーリング, Towairaito Hīringu): Asia's Sacred Gear and her main weapon of choice, she can heal Humans, Devils, Angels, and Fallen Angels alike. Since she has shown no actual combat skills, she relies on her healing abilities as a healer of her team. Asia learned how to expand the range of her healing field and send her healing powers as a projectile, although these are inferior to actual touch. In Volume 11, Azazel has said that she mastered her Twilight Healing more than other possessors in healing powers and time. She can also create a bow and arrow of healing power, and if the arrow is about to hit an enemy, it will disperse instead of healing them. Twilight Saint Affection (聖龍姫が抱く慈愛の園トワイライト・セイント・アフェクション, Towairaito Seinto Afekushon): Asia's sub-species Balance Breaker. Asia's Balance Breaker takes the form of a Golden Dragon Armor with red jewels that cover her body and grants her a field of absolute defence and protection. For a limited time, Asia can cover a field with tremendous healing energy and can negate any damage from virtually any sources. It does not negate the attack but rather it negates the damage that the attack would inflict. As Fafnir's aura is included as well, it also boasts immense defence on top of the healing ability. Asia can also used it to heal numerous allies at once on a wide range, using it to heal the allied youkais during the Evil Dragon War.

Personality When Xenovia was first introduced, she was shown to have a calm, quiet, and serious demeanor, putting her mission first and only speaking when necessary. She was also very cold, bordering on heartless, as she called Asia a witch for becoming a Devil (even though she became one unwillingly so she could be with Issei) and even went so far as to try and kill her. She later threatened to do the same to Kiba when he was technically a Stray. After being reborn as a Devil, however, she gains a very close relationship with Asia, being touched by her kindness and apologizes for calling her a witch when they first met. In battle, Xenovia appears to be a bit arrogant, stubborn, and rarely uses her head in attempting to overwhelm her opponents with pure power and strength instead of being subtle or using skills. According to Issei, her fighting style is comparable to that of a Rook despite being a Knight, referring to her as a "Power idiot". As Xenovia was raised in the Church, she lacks common knowledge on the life of a normal person, evident when she brought a box of condoms to school as well as wanting to give birth to strong children, and has chosen Issei as her mate. As the series progresses, it is shown that Xenovia has developed genuine romantic feelings towards Issei due to him protecting his comrades, even if he gets injured by doing so. As a result, she becomes more aggressive in seducing him, which proves that Xenovia is quite perverted as well, a fact that she is "cool" with. Demonic Power: Xenovia has all the powers and abilities common to Devils, including the power to cast spells. Natural-born Holy Sword Wielder: Xenovia is a natural-born holy sword wielder and capable of wielding any holy sword without artificial means like Irina. Even reincarnated as a Devil, Xenovia is still able to wield any holy sword without any issues. Enhanced Strength: Due to her years of training in the church, Xenovia gained superb arm strength, able to wield very heavy swords like Excalibur Destruction and Durandal with ease. After being reincarnated into a devil, her natural strength has been increased too. Enhanced Speed: Xenovia is able to move at superhuman speeds. She combines her speed with Durandal's destructive powers, making her a formidable fighter. Her speed is further enhanced by her Knight piece. However, Xenovia is considerably slower than Yuuto due to her being power-oriented as opposed to the technique-oriented Yuuto. When further combined with the Excalibur Rapidly, her speed is enhanced and she can move as fast as Masaomi. Immense Stamina: Xenovia has massive amounts of stamina and endurance. She was durable enough to confront Nero at the end of their match. She can still muster enough strength to use Cross Crisis enhanced by Crimson Destruction Dragonar. Master Swordswoman Durandal (デュランダル, Dyurandaru): Xenovia's main weapon, a unique-shaped single-edged blue broadsword that has a golden edge. It is a unique sword, to the point that it responds to the user, for her, Durandal releases a massive aura, which has destructive powers. Xenovia later learned that she can transfer Durandal's aura into another holy sword, as proven when she channeled its holy aura inside Ascalon. Excalibur's Scabbard (エクスカリバーの鞘, Ekusukaribā no Saya): The legendary Scabbard of Excalibur, which emits holy aura similar to a normal holy sword was originally sealed in an underground ruin. This makes Xenovia essentially immortal, healing wounds suffered from even a god-class being, however, this has its limits, but it allowed her to endure the light-based attacks of the Chief-God, Apollon despite being a devil and entrapped in a light cage.

Personality Rossweisse is known to be a very serious person, acting professional prioritizing work and study above all else since her youth, this however, caused her to miss out on romance, thus is extremely bitter and sensitive about not having a boyfriend and is quick to anger or sadness when made fun of. She has taken a liking to her role as a teacher in education for her students, making sure they understand her lessons and helping them whenever they're in a bind and is appreciated for it. Rossweisse has little tolerance for those who behave unprofessionally, especially for lewd acts at inappropriate times. When she lectures them on standards, they usually retort with her simply being jealous.

Despite her seriousness, she is stated to be clumsy and has a tendency to make rash decisions without informing anyone. She is highly susceptible to alcohol as one drink from it can leave her drunk and vomit for extended periods of time.

Like the other girls, Rossweisse acts like someone her age whenever she is on a date with Issei as she ended up acting shy when she was called cute.

However, instead of using demonic powers to cause different phenomena, she prefers to use calucations rather than using her imagination. Immense Magic Power: As Odin's former bodyguard, Rossweisse has considerable magic power enough to be recognized for her position.

She could teach others as she taught Asia about basic summoning magic, and other kinds. Rossweisse uses a high-level, intricate and self-invented magic circle, strengthening her spell's offense and defense, while restraining magic power to the bare minimum.

Age 16 Ravel Phenex is one of the many female protagonists of High School DxD. She is the only daughter and youngest child of Lord Phenex and Lady Phenex, and the younger sister of Ruval Phenex, an unnamed older brother and Riser Phenex. She is a second-year high school student at Kuoh Academy and a former member of Riser's peerage. Like her older brothers, she has inherited the powers of the Phoenix and possesses the power of fire, wind, and immortality. Upon Riser's defeat, she is traded to her mother, Lady Phenex before being traded to Issei Hyoudou, becoming his servant and second Bishop. Ravel is a beautiful young girl with dark blue eyes.

Ravel's body measurements are [B85-W59-H84 cm] (B33-W23-H33 in); height is 153 cm (5 feet 0 inches) and body weight is [47 kg]. Her initial outfit consisted of a light purple dress with dark purple accents and a blue bow at the front. At the back, three feather-like extensions mimicking a bird's tail protrude from the dress, which, when combined with her wings of fire, give her a bird-like appearance. Upon transferring to Kuoh Academy, she wears the Kuoh Academy girls' uniform, with the addition of a black sweater over her dress shirt. After joining Issei's peerage, during Rating Games, she wears a uniform that consists of a red button top with a white tie, a red skirt as well as a purple cape along with a blue satchel on her waist.

She's very loyal to her older brother, as she is seen diligently obeying his authority. She strongly believes that her brother is so powerful, no one could ever possibly defeat him. However, after witnessing his crushing defeat at the hands of Issei Hyoudou, she becomes attracted to him and later falls in love with him as the series progresses, albeit in a tsundere manner. Despite her young age, she's very intelligent, mature and perceptive, being able to understand the atmosphere of any situation as well as surmise Issei's thoughts just by simply looking at him. She is also shown to be a gifted strategist, serving as Issei's main strategist and second in command of his peerage. In this position, Ravel appears to be quite strict as she has her own expectations and standards when it comes to the suitability of someone to serve under Issei, such as when she denied Kuroka's offer to make Le Fay Pendragon Issei's contracted magician due to the latter's affiliation with the Khaos Brigade or when she was initially against letting Elmenhilde Karnstein join Issei's team. Ravel has also shown a ruthless side, being relentless in securing victory for her team. This is seen when she consistently read out the manga about Issei and Kiba to Tsubaki Shinra, despite the latter's obvious discomfort and pleas to stop. However, Ravel is also shown to be quite fragile hearted as seen when she cried when she believed she failed Issei after their defeat against Dulio's team in the Azazel Cup. Immortality: As a member of the Phenex Clan, Ravel shares her families' signature regeneration abilities, being able to regenerate lost limbs and recover from wounds instantly as demonstrated in Volume 25, when she regenerated from the damage inflicted by the Valkyrie Squad.

Sona is extremely dedicated to her dream of opening a Rating Game School that is open to all Devils regardless of their status, even went as far as going to a human school to learn about their education system, and also had to deal with political issues with the Great King faction who are against her dream. Despite her strict nature, Sona is also kind, generous, and compassionate as she helped Saji resolve his financial difficulties in raising his siblings after losing his grandfather, a fact that led Saji to fall for Sona. Sona's wish for opening a school was also to provide more education opportunities for lower-class devils in the Underworld who are restricted by an aristocratic society that limits their chances to learn. Despite being mostly calm and serious, Sona does have an emotional and delicate side such as her fragile ego when it comes to baking cakes, which (unknown to her), she is quite bad at.

It has the ability to stretch out its tongue, attaching to and absorbing the power of whoever it is wrapped to, and was later stated as also being able to redistribute that power to others. These lines seem to have something of an intangible quality, seemingly protected from physical attacks alone, as even an Excalibur was unable to cut them, harmlessly passing through one, before it's user activated it's holy aspect. After training, it took the form of a black snake around his arm, and became able to create multiple lines instead of one, absorb blood from a target, transfer power into items and convert his life-force into demonic power. Saji can also use these lines to perform three-dimensional movements.

Age 18 Vali Lucifer is the remaining descendant of the original Lucifer and the leader of the Vali Team that was previously affiliated with the Khaos Brigade, now a part of Team DxD. He is the wielder of the Longinus; Divine Dividing, being the possessor of the Vanishing Dragon, Albion. As such, he is the direct rival of Issei Hyoudou and Ddraig. Vali is a handsome young man with light silver hair and hazel eyes). He is often seen wearing a dark green V-neck shirt with a high-collared black leather jacket over it. He also wears burgundy jeans with a silver chain drooping down over them and black leather chaps with three bands encircling his right calf, and black shoes with black buckles. As with other Devils, Vali has black bat-like wings on his back. However, unlike other Devils, he possesses a total of eight. Vali also bears a great resemblance to his grandfather, Rizevim Livan Lucifer. Vali's height is 168 cm (5 feet 6 inches) and body weight is [60 kg]. Personality While initially appearing to be a cold, arrogant, overconfident and ruthless person, Vali has a calm, noble, and caring side in him as he cares deeply for his comrades. Wielding the Longinus "Divine Dividing" and his demonic powers, he refuses to use any other weapon besides the two, owing to a strong yet somewhat stubborn confidence in his capabilities. He is known to be a prideful young man and a battle maniac, being obsessed in finding strong opponents, and having said that he would gladly welcome death if there was no one strong enough for him to fight. While Vali does take some pride in being the descendant of the original Lucifer, but not in the same arrogantly fanatic extent as the other Old Satan descendants. This is most likely due to his childhood where his father, whose fanatical pride as Lucifer's grandson, was one of the two factors that led him to abuse his own son due to having greater potential than himself which led him to understand humility, the experiences of his childhood make him more realistic unlike the other Old Satan descendants like Shalba, Creuserey and Katerea who were too blinded by anachronistic pride of their lineage and their delusional ambition to acknowledge their limits and the power of others, thus explaining his refusal to help the Old Satan Faction. Unlike his ancestor and the other Old Satan descendants, Vali has absolutely no interest in world domination due to his humility and realistic worldview. Vali shows a proper attitude towards beings that deserve respect. Divine Dividing (白龍皇の光翼ディバイン・ディバイディング, Dibain Dibaidingu): His sacred gear and sole weapon, classified as one of the original 13 Longinus, which holds the spirit of the Vanishing Dragon, Albion.

Later on, Vali could use Half-Dimension without Balance Breaker, and gained Reflect, letting him redirect incoming attacks. IGH SCHOOL DXD WIKI Vali Lucifer Vali Lucifer is the remaining descendant of the original Lucifer and the leader of the Vali Team that was previously affiliated with the Khaos Brigade, now a part of Team DxD.

Unlike his ancestor and the other Old Satan descendants, Vali has absolutely no interest in world domination due to his humility and realistic worldview. Vali shows a proper attitude towards beings that deserve respect. Vali does possess a more vulnerable side, a side that he almost never shows. This side of him comes from the extreme abuse and persecution that Vali suffered at his father's hand. During the battle between Issei and Rizevim, he was captivated by his rival's fighting for his family the same time Vali felt lonely. While Vali never says it, Azazel has noted that Vali actually wanted to be raised in a happy family like Issei's, as well as being a normal person with no special lineage. This was shown in Volume 21 when Aži Dahāka pointed out that Vali's deepest desire is a family. His painful childhood caused by his father and Rizevim also led him to learn and understand compassion, a trait that other descendants of the original Satans did not have. Vali has repeatedly done selfless acts of kindness such as saving Asia from being disintegrated by exposure to the Dimensional Gap as well as helping Rias to stop Issei's life threatening rampage when he went berserk from activating Juggernaut Drive though he openly demonstrated a neutral demeanor when doing so. The greatest sign of his compassion is that Vali cared immensely for his mother who was the only person in his tragic childhood to have shown him kindness, leading him to withstand his father's horrible abuse for the sake of protecting her. Vali's strong resolve to protect his mother also extends to his younger half-siblings. During his death match with Aži Dahāka, the safety and protection of his mother and half siblings became the driving force and determination that spurred Vali to attain victory against the Evil Dragon. Due to the indirect fulfillment of his vengeance with his father and grandfather's respective deaths, Vali became more open in interacting with people, having accepted Goro's invitation to join them on a fishing trip at the beach simply for leisure and at Vidar's request, he moved into Kuoh Town to safeguard it from the Alliance of Hell, a significant change from his originally cold and battle obsessed nature which Issei noted in True Volume 2. Aside from battles, Vali is also utterly obsessed with noodles, in particular, ramen. He would go out of his way to visit famous ramen shops to eat ramen and even do culinary research on ramen. His devotion to his ramen research is such that he would travel between the Human world, Underworld and other mythological locations to procure special ingredients for his own ramen recipe. He is also extremely proud of his ramen research as he was completely shocked that his personally invented ramen recipe was criticized by Odin, Michael, Sirzechs and Azazel during the Pavilion Kingdom exhibition. Unlike his rival Issei, Vali is said to have an extreme lack of interest in the opposite sex, having no interest in romance since he was a child.[1] When pressed by Odin, Vali reveals that he has a slight fetish for women's butts (contrasting with Issei's everlasting fetish for women's breasts, although it's more downplayed and he would still prefer fighting), resulting in Odin calling him (and in turn, Albion) the Butt Dragon Emperor (ケツ龍皇 Ketsuryūkō). History He was born as the son of Razevan Lucifer, the son of Rizevim, conceived from his sexual fling with a human woman, making him a half-breed. Once it was revealed that Vali bore one of the Longinus, Divine Dividing, in addition to the power inherited from his great-grandfather, the original Lucifer, his father soon developed an inferiority complex toward his son who he viewed as a monster for holding those two powers. Because of the advice from Rizevim, Razevan started to bully and physically abuse Vali for his powers if he was so scared of him. Although he received physical abuse from his father, he was loved by his human mother who would tend to his wounds, attempt to protect him, and fed him whatever she could even if it was pasta, which became his favorite despite the bland taste. Vali soon ran away from home before being found by Azazel, who brought him in and raised him in Grigori, teaching him about both his Longinus and demonic powers with the intention of killing both his father and grandfather for being abused during his childhood. At 13-years-old, he started living with the members of the Slash/Dog Team, which included Tobio and Lavinia, the two members he viewed as older siblings, although he wouldn't admit it. At some point afterwards, the previous Ouryuu Nakiri caused trouble for him and Tobio resulting in him losing his position, which was passed down onto his cousin, Ryuuta Nakiri, who inherited the Sacred Beast and its name. At some point, Vali ended up meeting both the current Monkey King, Bikou, and Kuroka, a Nekoshou SS-Class Stray Devil, both of who became part of his secret team, where he sought to defeat Rizevim and to challenge stronger opponents. Powers & Abilities Devil Clan Full Symbol - Maou Lucifer Vali Lucifer’s Magic Circle. Immense Demonic Power: As the original Lucifer's great-grandson, he has extraordinary demonic power, and talent superior to other Satan descendants which he developed further through dedicated training since childhood in order to surpass his father and grandfather. Azazel stated that if his power was combined with Divine Dividing, Vali could become one of the strongest beings, and the strongest White Dragon Emperor of all time, past, present, and future. His demonic power lets him control Juggernaut Drive, using it as an alternative source before gaining its new form. In fact, Vali survived Samael's curse, although both Sun Wukong and Bikou's powers were needed to heal him. In D×D Lucifer, his demonic power alone could obliterate a 5,000 meter mountain using one blast and fight Aži Dahāka, who reached the Heavenly Dragons in power. Vali became a Super Devil candidate, and soon became one after fighting Hades following the Hell Disaster. Immense Durability: He is extremely durable with high pain tolerance which he developed from his childhood, when he was brutally abused by his father. He could endure vicious wounds from Fenrir, the monstrous wolf able to kill gods and later endured Samael's poison. Even after being viciously bitten by Aži Dahaka in a heavily exhausted state, he mustered the strength to use the Satan Lucifer Smasher. He was able to endure punches from Vasco Strada in his prime, then vicious attacks from Crom Cruach. Vali endured an assortment of attacks from Nezha's Divine Weapons and during the Hell Disaster, he withstood divine blasts from Hades and continued fighting despite his injuries. Vali's speed Vali overwhelms Kokabiel with his speed. Immense Speed: Vali has incredible speed, which using his Scale Mail allowed him to tear off Kokabiel's wings before he could react, with Yuuto comparing Vali's movement speed to light speed. He could avoid Loki's attacks in a manner that resembles an acrobat with ease, which even the extremely prideful Evil God was willing to acknowledge. During his battles against prime Vasco Strada using his silver armor, he circled around him at god-like speed to where he vanished and avoided Crom Cruach's attacks. In D×D Lucifer he could move at god-speed beyond normal perception, however, the Strongest Evil Dragon managed to react using his vast combat experience and honed battle intuition. Immense Stamina: He has tremendous stamina and endurance, being capable of maintaining his Scale Mail for one month, then endured being wounded by Fenrir, then activated his Juggernaut Drive. In Volume 24, Vali could continue fighting against Vasco even after the latter returned to his physical prime, then fought against Crom Cruach, the Strongest Evil Dragon, on even terms. He later competed in an intense match against Nezha, a Buddha rivaling Sun Wukong in power, as well as Hades, then later fought against Gvardora without rest before ultimately succumbing to his fatigue. Genius Intellect: Vali is highly intelligent. While under Azazel, he has acquired incredible knowledge on various mythologies, supernatural beings, and Sacred Gears. Having an interest in exploration and archaeology, he also investigates the mysteries of the world while exploring with his team such as Great Red, extinct civilizations like Mu and Atlantis, and ancedotes of legendary people. Master Combatant: Having received training from Azazel since childhood, Vali became an extremely proficient combatant capable of defeating the Cadre, Kokabiel without using his full strength. In Volume 4, he overwhelmed Issei, who was using an incomplete Scale Mail and even with the latter using Ascalon against him. After receiving training from Sun Wukong, his combat skills has improved to where he could defeat Aži Dahāka on his own, an enemy Vali previously fought against with his entire team and failed to defeat. When combined with his D×D Lucifer, Vali's skills allow him to fight on par with Crom Cruach. Master Magician: Vali has also shown to be extremely talented in using magic, most frequently Devil Magic enhanced by his demonic power and the power he absorbed through Divine Dividing. He is capable of learning Norse Magic in a very short period of time and was able to immediately and effectively use it during his fight with Loki, a Norse God familiar with the magic style. In Volume 20, he was able to produce a sword made from magic in order to slice off a weakened Rizevim's arm without using his Divine Dividing. Vali using defense magic circ Vali using defensive magic to shield himself against Nilrem Magicians attacks. Vali teleporting Vali teleporting the members of his team. Defensive Magic: Vali can use defensive magic to protect himself and others from powerful attacks. He used it to repel Issei Hyoudou during their fight and to defend against Shalba Beelzebub's attacks, despite being weakened by Samael's poison. Issei noted Vali's defensive magic is more sturdier than Diodora's whose magic is enhanced by Ophis's snake. Teleportation Magic: Vali is capable of using teleportation magic, as he is capable of teleporting to various locations and even being capable of sneaking into the Underworld without the permission of the Devil government. Summoning Magic: Vali is capable of summoning Gogmagog from the alternative dimension where he is kept. Flight: Being a half-Devil, Vali can fly using his 8 wings, in addition to the dragon wings provided to him by Divine Dividing. Equipment Vali flying with Divine Dividing Vali flying with Divine Dividing. Divine Dividing (白龍皇の光翼ディバイン・ディバイディング, Dibain Dibaidingu): His sacred gear and sole weapon, classified as one of the original 13 Longinus, which holds the spirit of the Vanishing Dragon, Albion. It takes form as a pair of light wings, enabling high-speed flight, while working opposite to the Boosted Gear, where it divides his target's power in half every 10-seconds, the halved power it added onto his; reaching his maximum limit, the excess power it released through his wings, keeping him at top performance. Later on, Vali could use Half-Dimension without Balance Breaker, and gained Reflect, letting him redirect incoming attacks. HS DxD - Scale Mail Divine Divding Divine Dividing: Scale Mail. Divine Dividing: Scale Mail (白龍皇の鎧ディバイン・ディバイディング・スケイルメイル, Dibain Dibaidingu: Sukeiru Meiru): Divine Dividing's Balance Breaker that creates a White Dragon Armor similar to Boosted Gear Scale Mail. In this form Vali is able to use Divide without the 10 second limit. Half Dimension (ハーフ ディメンション, Hāfu Dimenshon): The Divine Dividing also has the ability to halve the size of objects and living beings, and the user does not need to make any contact with the target to use this ability. Vali in his Juggernaut Drive Vali in his Juggernaut Drive. Juggernaut Drive (覇龍ジャガーノート・ドライヴ, Jagānōto Doraivu): A form unique to the Boosted Gear and Divine Dividing. The Juggernaut Drive temporarily removes the seal placed on the Heavenly Dragons granting the user immense power. The Juggernaut Drive, however, causes the user to lose sanity while having their lives devoured by the power. However, Vali is able to avoid this using his large amount of demonic powers as an alternative source of power instead of his lifespan; however, if used for extended periods of time, it will eventually cause him to go berserk. Even after deactivation, Vali suffered from immense exhaustion. Empireo Juggernaut Overdrive (白銀の極覇龍エンピレオ・ジャガーノート・オーバードライブ, Enpireo Jagānōto Ōbādoraibu): A new enhanced form that surpasses Juggernaut Drive. Vali obtained it after he successfully sealed all of the past possessors' consciousness. In this form, the color of his armor changes to silver. Like Issei's Cardinal Crimson Promotion, it does not consume his lifespan. When first introduced, Vali can only sustain this form for a short period of time before he must deactivate. By Volume 24, however, he is able to maintain this form for a much longer time. Compression Divider (コンプレッション　ディバイダー, Konpuresshon Dibaidā): In this state, Vali can use an enhanced version of Half Dimension, which halves a specific target constantly until they vanish from existence. This ability is very powerful as it killed Pluto in just a second and was able to compress Aži Dahāka's forbidden magic. Diabolos Dragon Lucifer (魔王化－『D×D』・L－ディアボロス・ドラゴン・ルシファー, Diaborosu Doragon Rushifā): Vali's DxD form. This form is the combination of the White Dragon Emperor's power and the Lucifer power that Vali synced through Ophis' blessing. Similarly to the Diabolos Dragon God Issei possesses, the armor is a mix of silvery-white and jet-black and also possesses the same organic characteristic. And unlike Diabolos Dragon God, he manifests the Crest of Lucifer instead of the symbol of Infinity(∞) on all of his Jewels. Vali gains twelve wings of Lucifer in this form, which can be ejected and turned into wyverns, similarly to the Dividing Wyvern Faeries that Issei is able to create. The power that Diabolos Dragon Lucifer possesses is enough to completely destroy a 5,000 meter-tall mountain in one attack and fight on par with Crom Cruach, the strongest Evil Dragon. Vali can only sustain this form for a short time. In this form, Vali's power surpasses that of the original Lucifer. Satan Compression Divider (サタン・コンプレッション・ディバイダー, Satan Konpuresshon Dibaidā): Vali builds up his power and releases an ultimate blast of silvery-white and black demonic radiance that halves anything within its range until it vanishes from existence. Azi Dahaka notes that this is not an ability or a technique, but a simple release of light. Satan Lucifer Smasher (サタン・ルシファー・スマッシャー, Satan Rushifā Sumasshā): Vali's own enhanced version of Longinus Smasher. Similarly to the Longinus Smasher, a cannon muzzle appears from the chest cavity which then fires a bombardment of silvery-white and black aura. Dividing Wyvern Fairy (白龍皇の妖精達ディバイディング・ワイバーン・フェアリー, Dibaidingu Waibān Fearī): In this form, Vali can detach his wings which then form into small white Wyverns that can also use Divide and Reflect, as well as using Half Dimension. The Wyverns are able to change into cannons that fires out a powerful shot of Lucifer’s aura. The Wyverns are also able to use Albion's hidden technique Reduce (減少, Genshō), an ability that releases a deadly venom which could kill anyone as it cuts down not only their bodies but also their souls, however, this is ineffective towards Ophis, Great Red and Ddraig. White Dragon Emperor Albion Manifestation (白龍皇アルビオン顕現, Hakuryūkou Arubion Kengen): Vali gained the ability to summon Albion into battle by performing a chant.

Kuroka, later named Kuroka Toujou is a Nekoshou, a rare variant of Nekomata. She is the older sister of Koneko Toujou, making her the firstborn daughter of Fujimai and her human lover. After their parent's deaths, she and her sister were turned by the Naberius clan into reincarnated Devils. However, after killing her previous master to protect her sister, Kuroka became an SS-Class Devil, one of the most wanted criminals. Age 22 She soon became a member of the Vali Team, who were previously affiliated with the Khaos Brigade, upon joining the Team DxD, she was exonerated from her previous crimes because of her actions. She is also one of Issei's fiancees. After the defeat of the Alliance of Hell, she became Xenovia Quarta's Bishop. Kuroka is a beautiful young woman with a voluptuous figure, long black hair with split bangs, and hazel-gold eyes with cat-like pupils. Her body measurements are [B98-W57-H86 cm] [B39-W23-H35 in]; height is 161 cm (5 feet 3 inches) and body weight is [49 kg]. Her attire consists of a black kimono, a yellow obi, a set of golden beads, and an ornately detailed headband. The kimono features a red interior and it is open at her shoulders, giving view to her large breasts which rival those of Rias and Akeno in terms of size. In her Nekomata form, which she is in all the time, she grows a pair of black cat ears and two black tails. Personality At first, Kuroka was shown to be rather malicious, with her aura described as being more "outright evil" when compared to the "vice" of Azazel's. In the past, she was said to have murdered her previous master, as she was unable to gain control over her Senjutsu, and was driven mad as a result. This initially seemed true, with her first appearance having her declare her intention to kill Rias, Issei, and her sister after the latter refused her, and that was after using poison to weaken Koneko and Rias, all after commenting on her intention to use Koneko as "a piece under my control". However, she later claimed that vicious display was just her "going with the mood". Under normal circumstances, Kuroka is rather playful, nonchalant, and simple-minded, simply enjoying teasing people. She's rather vulgar, often using her beauty and sensuousness as a weapon among her arsenal of teasing others, most notably Issei. Fenrir once stated his belief that because of these traits she wastes her potential. Kuroka is also lustful and perverted as she enjoyed openly doing sexual things with Issei without restraint and is also proud of her sex appeal and breasts as she is offended when Bikou insulted her breasts. When Issei lost his perversion as a result of the Alphecca Tyrant, Kuroka was dismayed calling it a serious illness. Above all else, despite her mischievous nature, she can be a kind and compassionate woman who loves Koneko more than anything, wanting peace more than anyone. To raise Koneko after becoming orphans, Kuroka agreed to become a reincarnated Devil. She murdered her former Master to protect her younger sister from him, though it meant she'd become labeled as a criminal and continued to play that part. However, Kuroka often has a hard time showing this side of herself, often opting to tease her younger sister instead. She expressed an interest in having strong children, at first having propositioned Vali, but was rejected, then turning her attention to Issei, both of whom are the Heavenly Dragons' hosts. Her reason being because she wanted her species, the Nekoshou, to bloom once again, their kind being inherently rare. Before and after moving into the Hyoudou Residence, Kuroka is often described as a freeloader. Most of the time, she's seen playing video games and being a glutton, never assisting around the house and instead leaves that work to the others, unlike Le Fay. After being called out on this fact, Kuroka often offered Issei sex as a means of getting out of it. Like her sister Koneko, Kuroka is also shown to have a big appetite, as she would eat other people's snacks without asking and accompanied the Gremory group on their fishing trip solely to eat the fish they caught, claiming all the nutrients go to her breasts. Kuroka is the older sister of Koneko (then known as Shirone) who was born to a Nekoshou called Fujimai and a human researcher. After losing her parents, she and her sister were later taken in by an unnamed Devil from the branch family of the House of Naberius, and she was reincarnated as the Devil's Bishop using up two Evil Pieces. Demonic Power: As a Devil, Kuroka has all the common skills and powers of one, including the power to cast various spells. She primarily uses this in tandem with her Senjutsu and Youjutsu techniques. Koneko has stated that her power rivals that of an Ultimate-Class Devil and even with Tannin's help, it wouldn't be easy to capture her.[3] Immense Magic Power: As a Bishop who took two Bishop Pieces, Kuroka is able to enhance her magic and demonic powers to a greater extent than regular Bishops. Youjutsu Master: As a Nekoshou, she is highly talented in Youjutsu, being able to perform spells common among Youkai, whether for offense, defense, or support. She is skilled enough to instruct her younger sister in it, as well as effectively support her teammates in combat with her Youjutsu skills. A testament to this is the time, Kuroka could research and developed a Youjutsu poison powerful enough to affect Sun Wukong using his descendant as the test subject, causing irregular effects on Bikou with spells, curses, and medicines. Poison Mist: She can create a poisonous mist effective on Youkai and Devils, but Dragons and Dragons-based Sacred Gear users are immune to it. However, it's possible for Kuroka to strengthen and adapt her poison to affect particular beings, such as Sun Wukong through examining his descendant's constitution, being powerful enough to greatly weaken him despite brief exposure. Illusions: Kuroka is able to cast illusions such as creating mirage copies of herself to throw her opponents off. Senjutsu Master: Among her many talents, Kuroka became exceptional in Senjutsu, strengthening herself using Ki and sensing auras. She can control nature, turning the ground into mud to seal the movements of one of Fenrir's sons;[4] controlling the earth and plants, using them to attack.[5][6] She can combine Senjutsu and Youjutsu to release a concentrated energy blast. Touki (闘気, Fighting Spirit): Kuroka covers herself in an aura of ki, increasing her strength, defense, and speed. Kasha (火車, Burning Chariot): Kuroka can summon multiple big wheels that are covered in black flames. Stealth: Kuroka uses her Senjutsu to conceal her presence from other Devils by changing her ki flow.

Sirzechs Lucifer, formerly known as Sirzechs Gremory, was the Satan Lucifer who was in charge of Domestic Affairs, prior to the events of the Evil Dragon War. He is the former heir to the Gremory Clan, the eldest child of Zeoticus Gremory and Venelana Gremory and the older brother of Rias Gremory. Sirzechs is also the husband of Grayfia Lucifuge and the father of Millicas Gremory. Known as the Crimson Satan, he is the former leader of the Four Great Satans who ruled the Underworld with the former title of "Lucifer". His peerage is said to be the strongest group in the Underworld. Age 22 Sirzechs is a handsome man who seems to be in his early 20's. He has shoulder length crimson hair and blue eyes (blue-green in the anime season 1-3) inherited from his father, Zeoticus, similar to Rias. In fact, Issei has described him as the male version of Rias. In his true form, Sirzechs takes the form of the Power of Destruction in the shape of a human with crimson aura. Personality As a Gremory, Sirzechs is shown to be very kind and caring towards others, preferring to have things sorted out through talking instead of fighting. He also has a very laid-back personality, preferring to do things at his own pace and causing his wife to punish him for it. Humorously, when he's up to his usual antics, the mere mention of his wife's name is enough to make him apologize immediately. However, Sirzechs does have a serious side, which he has only revealed twice: during his fight against Creuserey Asmodeus and his confrontation with Hades. Sirzechs has shown to possess an unbreakable and selfless determination to protect the people he cares about even if it means sacrificing himself. During his youth, Sirzechs joined the Devil Civil War after his youth choir of innocent Devil children was unreasonably killed by the Old Satan Faction solely to prevent any more victims. When Trihexa was revived, Sirzechs chose to join the neverending battle against the Apocalyptic Beast in the Isolation Barrier in order to prevent it from endangering the world even if it meant millennia of separation from his family including his beloved wife Grayfia and son Millicas. When Sirzechs was born, he floated in the air releasing the Power of Destruction which was so powerful even when he was a newborn, it could disintegrate or deform surrounding furniture and decoration without a trace. None of the doctors could touch him, except Venelana who held her son and asked her husband Zeoticus on what his name would be to which he replied, "Sirzechs". At 17 years old, in the Gremory castle town's public hall, Sirzechs would play piano and sing nursery rhymes with children. He was very close with the people of the Gremory territory. Attending a social gathering attended by Beelzebub's relative, he got into a fight with the prince by protecting the heir of Oriax until Grayfia intervened. Sirzechs fell in love at first sight with the silver-haired beauty. Power of Destruction (滅びの力, Horobi no Chikara): Sirzechs inherited from his mother the Bael's Power of Destruction which is further enhanced by the superior demonic power talents of his Gremory lineage. He mastered Power of Destruction to an overwhelming level, eliminating anything it touches. Azazel has stated the main reason why Sirzechs was chosen to be a Satan was due to his mastery of it. Ruin the Extinct (滅殺の魔弾ルイン・ザ・エクスティンクト, Ruin za Ekusutinkuto): Sirzechs' special technique, also known as Demonic Bullets of Annihilation. Through years of training along with the demonic power talents of the Gremory, Sirzechs has become able to shape his Power of Destruction into numerous, highly mobile spheres able to eliminate things without a trace as well as circumvent the defenses of his target, resulting in minimal damage to the surroundings. He was able to precisely guide his destruction energy sphere into Creuserey Asmodeus' body through his mouth and destroy Ophis' snake without causing any damage to the latter. During his fight with Issei, Ddraig noted that Sirzechs' Power of Destruction is at an abnormal level, speculating that Sirzechs may have placed all his talent and effort into the concept of “eliminating," even able to affect beings significantly stronger than himself, such as Trihexa, something that overturns the normally Raw Power-based sense of Highschool DxD. Human-Shaped Aura of Destruction (人型に浮かび上がる滅びのオーラ, Hitogata ni Ukabiagaru Horobi no Ōra): Sirzechs' true form. He can convert himself into the Power of Destruction that destroys everything regardless of his will. The full releasing of his powers was enough to cause an earthquake felt in the entire Realm of Dead. According to Azazel, Sirzechs compresses the Power of Destruction into a human shape that releases ten times more demonic power then original Lucifer. This form's power is so strong that Azazel commented that Sirzechs could have easily defeated Hades, one of the "Top 10 Strongest Beings in the World". However, Sirzechs is unable to fully control this form as the Power of Destruction spreads without his command. Devil Magic Circle Sirzechs Lucifer

According to him, the only reason he became a Satan was because Sirzechs became one himself,[1] as well as declaring that whoever became Sirzechs' enemies would become his, declaring this to Shiva.

He also likes to fight strong people, to the point that Rias Gremory, his own cousin, called him a battle maniac. He is shown to be a kind-hearted and compassionate person and has a very straightforward personality. He even shows unconditional kindness to his estranged half brother. Sairaorg is extremely dedicated to fulfilling his dream to create an Underworld where any Devil regardless of their background can make their dream come true as shown in his unbreakable determination in protecting Auros Academy, which is an important stepping stone to his dream, from Grendel's rampage. Sairaorg takes great pride in his strength and the fact that he trained for it; this is shown when he felt insulted by Bedeze Abaddon's offer to give him a King Piece. He possesses a great deal of pride and honor as both an heir and warrior, though he does not possess the arrogance that his clan possesses. He is very mature and composed enough to handle things, although he and his mother have been shunned from the rest of his clan due to the abuse that he received from his father and other clan members (not including Zekram Bael). History Born as the eldest son of the Bael Clan, Sairaorg didn’t inherit the Bael's trademark Power of Destruction that Rias and her brother inherited from their mother, who came from the Bael Clan. Because of this, his younger half-brother Magdaran Bael was appointed to become the next heir of the Bael Clan. Sairaorg and his mother, Misla Bael, were then shunned and scorned by the Bael Clan, including his very own father, to the point of being sent to the countryside of the Bael territory. During his time there, Sairaorg was constantly bullied by other Low and Middle-Class Devils, until Misla advised him to become strong in different ways. Sairaorg then started training his body to its utmost limits to become powerful and due to this, he defeated his younger half-brother, which made him the next heir of the Bael Clan. Sairaorg desires to become Satan to prove his worth even with his lack of special demonic powers. Sometime before the series, Sairaorg found Regulus, the Lion King, sealed in the Longinus, Regulus Nemea, after its possessor died and it materialized itself. Sairaorg then tamed Regulus and made it his servant through 7 Pawn Evil Pieces. Powers & Abilities Lion Tamer: Sairaorg has attributed himself to be able to tame Regulus Nemea due to this trait inherited from his mother; Misla Bael, who hails from the Vapula Clan, which has the power to tame lions. Touki (闘気, Fighting Spirit): He has enormous Touki, achieved from rigorous physical training, enough that just by releasing it he can generate wind pressure and crack the ground. It increases Sairaorg's physical prowess & durability, enough to protect him from both Rossweisse's Full Burst and Ex-Durandal, his potent life-force even allowing his right arm to remain after being cut off by the holy sword instead of vanishing. Sairaorg can focus his Touki into his fist to release a shockwave able to cause a great amount of devastation to a Rating Game field. His life-force is said to make it possible for him to use Breakdown the Beast for a limited time. Immense Strength: In search for strength different from demonic power, Sairaorg rigorously trained his body, developing immense physical power even by devil’s standards that allowed him to defeat Magdaran for the position of Clan Heir, and become the Strongest Young Devil. He outclassed Zephyrdor, and later Issei in Scale Mail, cracking the armor from his fist's pressure alone despite missing, & then nearly broke through with a direct strike even after Issei promoted to Rook & Boosted, earning Ddraig's praise, all while wearing restraints. He defeated Kiba, Xenovia, and Rossweisse with ease after releasing said restraints & his Touki, was still stronger than a Queen-promoted Issei to the point of shattering his helm with one strike before he Boosted (though only rivaled him in the anime), & surpassed his might using the Regulus armor, to the point of almost killing him with one punch that smashed through Triaina Rook’s enhanced defense. He fought Issei in his Crimson Armor, their clash shaking and cracking the artificial space, and pushed Issei to the limit despite losing. could hit away all the missiles of Heracles's Detonation Mighty Comet with his fists, & then, while using only minimal strength, struck Heracles with such power that he destroyed a building behind him simply from the aftershock of his punch. Sairaorg fought Grendel head-on while in Regulus' armor, throwing him into the air despite severe injuries from the giant Dragon and Holy Flames. When enhanced by Imperial Purpure, he outclassed Bedeze, the 3rd Ranked champion of the Rating Games, breaking his portals and releasing shockwaves over a great distance Issei believes that Sairaorg rivals or surpasses Satan-Class in that form, & when so empowered he knocked back Star Blaster's blast with one punch, then defeated Balberith, albeit the latter is said to have fought half-baked His strength alone has earned Shiva's praise, describing it as "genuine destruction". Cao Cao also stated Sairaorg's strength made his True Longinus worthless in comparison. Immense Durability: He developed tremendous, almost ludicrous durability and pain tolerance from training, taking straight hits from Issei in Scale Mail, before and after promoting to Rook, only getting a bloody nose from the latter strike. He endured multiple attacks from Kiba, Xenovia and Rossweisse without serious injuries; his arm remained despite being cut off by the two Knights wielding Ex-Durandal, and he kept on fighting. Since then, Sairaorg has taken multiple destructive blows from opponents, such as Heracles; the most notable being from Incinerate Anthem and followed by a stomping from Grendel, afterwards tossing the latter into the air despite serious injuries and then continuing to fight the savage Dragon seemingly unhindered. He later withstood his own punch donned in his lion armor, and swiftly recovered enough from his battle with Bedeze to rejoin the Evil Dragon War. His most notable feats were withstanding blows from the True Longinus and Star Buster Star Blaster, deflecting the latter while using Imperial Purpure. Immense Stamina

Venelana can also strike fear at others when she's angered, such as her husband, Zeoticus. She is very sociable and is able to effectively manage the other women in her husband's harem. Venelana is quite the intelligent woman when it comes to the business world, as she possesses a talent in finding hidden gems that have not yet been properly evaluated at their true price, due to having good connections. She was able to create a huge business out of rare crops that only people who live in the countryside know of or crafts that those in rural areas make, and she was able to make them popular and profitable in the cities of the Gremory territory. History Venelana is the eldest daughter of the House of Bael that is famous for their Power of Destruction. Immense Demonic Power: Venelana is powerful enough to be known as the strongest woman from the house of Bael of all time.

He is the son of Sirzechs Lucifer and Grayfia Lucifuge, the nephew of Rias Gremory, and the grandson of Zeoticus and Venelana Gremory. Although his father was Lucifer of the Four Great Satans, his title does not apply to Millicas, as it was only required for Sirzechs and is not an inherent position, thus Millicas' family name is Gremory. Millicas is a cute young boy with short crimson hair inherited from his father, Sirzechs, and red eyes (blue-green in season 3 of the anime) which he inherited from his mother, Grayfia. Personality Millicas is shown to be a well-mannered boy. Despite his young age, Millicas is shown to be very responsible even planning about his future peerage. He also prefers being referred as "Millicas" rather than "Millicas-sama" by the people close to him. History Millicas was born a few years before the start of the series. Powers & Abilities Demonic Power: As the son of Sirzechs Lucifer and Grayfia Lucifuge, Millicas possesses an incredible amount of talent in demonic power, which Issei said to be at the same level with Vali.

Power of Destruction (滅びの力 Horobi no Chikara): Like Sirzechs and Rias, Millicas also possesses the Power of Destruction, which he inherited from his grandmother. Despite Millicas' young age, he has shown to have better control of his Power of Destruction than Rias, being able to shoot them like a shotgun as well as controlling its direction.

Riser Phenex is the third son of the Phenex Clan after his elder brother and an unnamed second older brother. He is the youngest son of Lord Phenex and Lady Phenex, the younger brother of Ruval Phenex and an unnamed older brother, and the older brother of Ravel Phenex. He was the main antagonist of Volume 2 of the novels. He was once Rias Gremory’s fiancé who has inherited the powers of the immortal bird, Phoenix, granting him immortality and instant regeneration. His all-female peerage consists of fourteen members. Riser is a tall and handsome young man in his early 20's with short blond hair and dark blue eyes. His outfit consists of a burgundy blazer with gold embroidery on the right with matching pants and black dress shoes. Underneath his open blazer is a white dress shirt that is not fully buttoned (just one button short), giving a slight view to his chest. Personality During his introductory volume, Riser is shown to be an arrogant, aggressive playboy with a holier-than-thou personality, tongue-kissing two of his girls just to agitate Issei and making improper advances on Rias. Kiba pointed out that Riser has no qualms in "sacrificing" his peerage members during Rating Games if it meant winning against opponents, being something he favors, taking advantage of the fact that he has a full set. He is also condescending towards lower-class Devils, mocking Issei on his improper use of the Boosted Gear after the latter was defeated by Mira in one blow and labeling him as a weakling. Despite this, Riser does show an honorable side, as he allows Rias and her peerage ten days to prepare themselves for their Rating Game, knowing he would simply crush her and her peerage had she not accepted. Like most devils, Riser has no good opinion about humans or the Human World, in general, previously mentioning that he hated the wind and fires of the Human World. Later, after his defeat by the hands of Issei, Riser fell into a slump following his defeat, not moving out of his house after the loss. It is also explained that Riser developed a fear of Dragons as a result of losing to Issei, and he became traumatized, upon seeing Issei and Dragons he would quake in fear. Riser is also shown to be a pervert, not only purposely creating an all female peerage, but also his desire to see Rias and Akeno's breast partially being what brings him out of his slump. After recovering from his trauma, Riser seems to have reformed from his old ways, showing a degree of respect for his former combatants, especially Issei. For example, in Volume 10, he gives Rias advice on Rating Games prior to her match against Sairaorg, and in Volume 12, he gives his condolences to Ravel and Rias after Issei's supposed death. In the Extra Life of DX.1, during their rematch seeing how Rias' Peerage easily defeated his, instead of being enraged and insulting everyone, he humbly accepted the result. He began to show interest in fighting strong foes, especially Issei, despite the clear difference in power. Riser states that he does not mind losing, saying instead that he will use it a stepping stone to get stronger which is another sign of his maturity. Riser is the third (and youngest) son of the Phenex family and the second-youngest sibling in the family, behind his sister Ravel. At some point before the start of the series, his family set up an arranged marriage between him and Rias (with her family's approval, as well) in an attempt to unite the two families and to preserve the bloodline of Pure-Blooded Devils. Powers & Abilities Demonic Power: As a Devil, Riser has all the common skills and powers of one, including the power to cast spells. It is shown Riser can teleport himself to any location. In the LN, Riser was stated to possess a rainbow-colored demonic aura. In DX.1, his demonic power increases after training and manages to fight against Issei in Balance Breaker evenly, managing to put up a fight against his Crimson Armor despite being overwhelmed by its power initially. Hell flame and immortality

Diodora Astaroth was the former heir of the Astaroth Clan. He was the son of Lord and Lady Astaroth. He was a gentle-looking, handsome young man with blond hair as depicted in the novel (dark green hair in the anime).

He also has golden eyes, but they are almost always closed or squint Ed. Age 19 Personality While initially appearing to be a gentle, well-mannered, and charismatic young man, Diodora was in fact a narcissistic, sinister, vile, callous, and wicked person who would do "whatever it takes" to achieve his desires. He had an utter obsession with nuns and holy-maidens, which was exemplified by the fact that all of his servants were once nuns and maidens that he had acquired after "breaking" them. He enjoyed seeing them with expressions of pain, sadness, and despair which he found to be an ultimate form of entertainment. This showed Diodora to be an incredibly sadistic Devil. He was also very imprudent, as was exemplified when he used the Ophis' power in a careless way despite Shalba Beelzebub forbidding him from doing so, as it allowed the Three Factions higher-ups such as Sirzechs and Azazel to catch wind of the Khaos Brigade's plot due to noticing his irregular increase in power. Despite this, he is very intelligent, deceptive, and manipulative, capable of manipulating others into doing his bidding. An example would be how he managed to convince the nuns and holy-maidens who would become his servants that he was in love with them, only to use them for his own twisted pleasure, showing that he is also incapable of love. He was shown to have a loathing towards Dragons and those connected to them: he once called Issei a "filthy dragon". After being overpowered and defeated by Issei thus breaking his will to fight, he became immensely fearful of him and dragons as well. Demonic Power: Diodora showed some skill in using his demonic powers, as he was able to hurl conjured blades at Issei and create barriers during their fight.

Equipment Ophis' Snake: After joining forces with the Khaos Brigade, he obtained a snake which he used to increase his power. He used it during his Rating Game against Seekvaira Agares and his fight with Issei Hyoudou. He lost the snake during his confrontation with Issei Hyoudou.

Before her coma, she made Sairaorg promise her that he would become stronger than anyone else.

Azazel is the former Governor General of the Fallen Angels and Grigori. He also previously served as a Chemistry teacher at Kuoh Academy and as the advisor of the Occult Research Club, prior to sealing himself in the Isolation Barrier Field. Azazel is a tall man appearing to be in his twenties with an average build, black hair, golden bangs, and black goatee. He also possesses twelve jet-black feathered wings that grow out from his back. It is described by Vali to be a never ending black. Age 26 During the Summit, Azazel wore a V-neck maroon long-coat with a wide, open high-collar that opens up at the hem. The long-coat also featured two black belts around the waist and four black bands on each arm, two of the bands at the wrist and the other two near the elbow. He wore grey slacks and brown shoes. After the events in Volume 4, he loses his left arm, but replaces it with a prosthetic arm made from his Sacred Gear research. When he served as a Chemistry teacher at Kuoh Academy, Azazel wore a knee-length dark blue blazer with a lighter blue dress shirt, a black waist coat, and a red tie. He wore faded-purple slacks and black dress shoes. Azazel's height is 188 cm (6 feet 2 inches) and body weight is [82 kg].

Azazel loves to collect things, (shown when, after Issei introduced him to video games, he collected every console) and a research fanatic, especially on Sacred Gears. He is also shown to be pacifistic, preferring to talk his way out of troubles rather than resorting to violence. He has been shown to care deeply for his fellow Fallen Angels, Shemhazai and Baraqiel. Azazel has also been shown to be extremely charismatic, being able to endear his Fallen Angel followers. Azazel has complicated feelings about the fact that many of his friends and acquaintances are all married and have a family. Azazel is also perverted because of his fondness for breasts, and also due to the fact that he has stated to have had hundreds of harems over the millennia. Not to mention that his stated reason for becoming a Fallen Angel all those millennia ago was lust. Even before he became a Fallen Angel, he was already a pervert as he would fantasize about touching/seeing Gabriel's breasts, the most beautiful woman in Heaven as evident when he encouraged Issei to use Dress Break on her. Azazel is also very compassionate as he would do whatever he can to help people in need. The most prominent example is when he adopted Vali and cared for him as his own son, after learning of the immense abuse and cruelty Vali suffered by his father and grandfather. However, there seems to be a hidden former side to Azazel as Shiva told him that he is the most sinister of the Fallen Angels, despite wanting to spread peace.

As the Governor General of Grigori, it is noted that his light powers are superior among other fallen angels ADVERTISEMENT Appearance Azazel is a tall man appearing to be in his twenties with an average build, black hair, golden bangs, and black goatee.

However, there seems to be a hidden former side to Azazel as Shiva told him that he is the most sinister of the Fallen Angels, despite wanting to spread peace. History Originally an Angel from Fifth Heaven, during his time there, Azazel had once written a report on his Artificial Sacred Gear, the Blazer Shining or Darkness Blade, which was published by Michael during the war much to his embarrassment. Azazel later lost his place in the Heaven after having sex with a human woman and became a Fallen Angel as punishment from God. Shortly after that, he created the Fallen Angels' organization, Grigori, and became its Governor General. During the Great War between the Three Factions, the Fallen Angels were the first to retreat due to Azazel's order after he had lost many of his subordinates. After retreating from the Great War, Azazel started to research Sacred Gears, creating Artificial Sacred Gears and other objects related to them. He also made a contract with one of the Five Great Dragon Kings, Fafnir, during his research and created his own Artificial Sacred Gear: the Down Fall Dragon Spear. At some point, before the series begins, Azazel found a young Vali Lucifer who had been abandoned by his parents, took him to Grigori, and taught him how to properly use his powers along with his Sacred Gear while raising him. Powers & Abilities Immense Light Power: As a Fallen Angel, Azazel has the ability to use light power to create various effects.

He can easily generate numerous light spears and shoot them like arrows without the slightest sign of exhaustion, being able to create a gigantic light spear before turning it into several light arrows. Immense Strength: As the First Governor General, Azazel has immense strength rivaling Satan-Class Devils, being superior to Shemhazai, Baraqiel, and Kokabiel, rivaling the Archangel, Michael. During the Three Factions Conference, he fought against Katerea, an Ultimate-Class Devil and a Leviathan descendant even without using his Down Fall Dragon Spear. Donned in his Dragon Armor, he fought Cao Cao, the Strongest Longinus user; and in Vol 11, Pluto, an Ultimate-Class Grim Reaper. In Vol 16, Azazel has shown incredible physical strength able to destroy the nearby wall using a single punch. Immense Durability: Azazel has remarkable durability and pain tolerance, showing no reaction to cutting off his own left arm after freeing himself from Katerea's tentacle arms who planned on self-destructing. He later survived a surprise attack from Vali before casually emerged relatively unharmed following his betrayal. Azazel endured a light blast from Cao Cao's True Longinus with only slight burns. Immense Speed: Azazel is capable of moving at God-like speed, being able to appear behind his opponents without them noticing. Down Fall Dragon Spear: An Artificial Sacred Gear that has one of the Five Dragon Kings, Fafnir, sealed inside of it after he made a pact with him.

It increases Azazel's offensive and defensive capabilities and allows Azazel to summon a two-pronged Spear of Light. However, the armor isn't as powerful as genuine Scale Mail armor as Cao Cao noted that Azazel can't reflect Fafnir's power with it. Blazer Shining or Darkness Blade: An Artificial Sacred Gear that takes the form of a sword with a mixture of light and darkness with high destructive powers. Blazer Shining or Darkness Samurai Sword: An Artificial Sacred Gear that takes the form of a katana sword.

Kokabiel has the appearance of a tall, pale man with long black hair and narrow, blood red eyes. Unlike other Fallen Angels, Kokabiel has pointy, elf-like ears. Kokabiel possesses five pairs of black wings, though one of them was ripped off by Vali when he was sent to retrieve the Fallen Angel. 100+ He wears a black robe with detailed accessories and purple shoulder pads with gold streaks on the side. Personality Kokabiel vehemently believes that the Fallen Angels are the strongest race and strives to prove it by any means necessary. In Volume 4, Sirzechs mentioned that Kokabiel enjoys war and bloodshed, compared to Azazel who enjoys peace and advancement. To that end, he wanted to start another Great War but faces strong objection from Azazel. As such, he has a strong hatred towards Azazel, believing that he is defiling the Fallen Angels' culture and reputation by performing Sacred Gear research and allowing humans with Sacred Gears to join Grigori. He is also shown to be highly arrogant and boasts a great deal of confidence in his power, as seen when he actually told and waited for Issei to boost his power to his limit and transfer it to Rias because that was the only way they would be able to hurt him. History Originally an Angel from Fifth Heaven, Kokabiel is one of the leaders of Grigori and one of the few Fallen Angels that survived the Great War. Unlike the other leaders of the Fallen Angels, Kokabiel desired to continue the war but faced strong opposition from Azazel and Shemhazai which eventually resulted in his betrayal and rebellion. During the Second World War, Kokabiel fought against Vasco Strada, the former wielder of Durandal, and was eventually cornered by the latter. Immense Light Power: As a Fallen Angel, Kokabiel has the ability to use Light Power to create various effects. As one of the Cadre, his Light Powers are superior to that of other lower-ranked Fallen Angels. Light-Based Weapons: Kokabiel is very proficient in using his light-based weapons, being able to create Light Swords and spears that are larger than Kuoh Academy itself. Immense Strength: As a Cadre of the Fallen Angels, Kokabiel can create weapons of light with ease, and likely wields power equivalent to a Satan-Class Devil. This was shown when Kokabiel was able to easily overwhelm the Occult Research Club alone and Azazel stated that at that time Kokabiel was so strong that Issei was incapable of defeating him, no matter how many times he boosted his power with Boosted Gear. When he fought Vali Lucifer during the latter's retrieval of him, Vali noted that his power after being divided three times by Divine Dividing is now that of a mid-class Fallen Angel, indicating that Kokabiel is eight times stronger than one. Immense Durability: Kokabiel was able to take Rias' attack that was boosted many times by Issei's Boosted Gear with only slight burns. Steel Feathers: He can also fire the feathers of his wings as projectiles to pierce his opponents with the feathers being as hard as steel. He is also capable of using his wings for both offense and defense, as shown when he fought the Occult Research Club.

Baraqiel is the current Vice Governor General of the Fallen Angels and Grigori. He is the father of Akeno Himejima and the widower of Shuri Himejima. Baraqiel is also one of Azazel's closest friends, alongside Shemhazai. Age 47 Baraqiel has the appearance of a middle-aged, gruff-looking man with black hair, a matching beard, and a muscular body. Originally being a Cadre-class Fallen Angel, Baraqiel possesses ten black wings[1]. Personality Baraqiel has a serious, rigid warrior-type personality. Baraqiel is very protective of his daughter, Akeno, and is initially hostile to Issei due to his misconception of him being "a Dragon that devours breasts". This also suggests that he is naive to jokes, taking them in a literal sense. He also has a masochistic side to him, the inverse of which is inherited by his daughter. History Originally, Baraqiel was one of the Angels from Fifth Heaven, where he became known as the Lightning of God. But, he soon became one of the first Angels that fell alongside Azazel and Shemhazai, eventually becoming one of the Leaders of Grigori, an organization that soon became one of the Three Factions. He and the others fought in the Great War against the angels and devils until the death of the God of the Bible and Four Maou in the aftermath. In the past, Baraqiel was injured and found by Shuri Himejima who nursed him back to health leading to them falling in love with one another, leading to marriage. Their union also led to them giving birth to their only daughter, Akeno Himejima. However, the Himejima Clan couldn't accept her as a fallen angel-human hybrid. At some point, when Baraqiel was called back to Grigori by Azazel, the Himejima Clan members, led by Suou Himejima, took advantage of this to kill Shuri and Akeno, but they only managed to murder the former before Baraqiel arrived to save his daughter. However, he was rejected by her who developed a hatred for him and her fallen angel lineage, which led to her mother's death. Powers & Abilities Immense Light Power: As a Fallen Angel, Baraqiel has the ability to use light power to create various effects. Light-Based Weapons: While not shown in the light novel, in the anime, Baraqiel has shown that he can create a light sword. Holy Lightning (雷光, Raikō): Baraqiel's signature ability as a former Angel who bears the Lightning of God, one that combines light and lightning together. It is reputed to be number one among Fallen Angels in damage output in a single strike, being able to kill High-Class Devils and wound Ultimate-Class Devils in one strike, and is ten times stronger than his daughter's. Baraqiel's mastery is enough for him to create spears, creating thunder clouds to make Holy Lightning bolts rain down on his opponents, as well as infuse it into his punches and kicks, letting him fight Issei in his Crimson Armor, after it was strengthened as a side effect of his Dragon Deification, on equal terms. Immense Strength: As a former Cadre, Baraqiel possesses great power, able to hold his own against a lower-end Satan-class powerhouse like Issei in his crimson armor, although he admitted that, even with his power enhanced by anger, he still wouldn't beat Issei in a contest of power. By possessing God`s Holy Lightning, he can kill a High-Class Devil or injure an Ultimate-Class Devil in a single strike. Immense Durability: Baraqiel is shown to be very durable as he was able to endure several blows from Issei in his Cardinal Crimson Promotion. Master Hand-to-Hand Combatant: Baraqiel is shown to have great skills in hand-to-hand combat, being able to hold his own against Issei. He can also combine them with his Holy Lightning to further increase the power of his physical attacks. Master Tactician: Baraqiel has shown to be able to implement a genius strategy, as shown in Volume 22 where he lured Issei into a corner by manipulation, completely tricking him into not noticing his plan. This is further proven when trapping Issei was all but a feint for him to use "Castling", swapping places with Rossweisse so that Baraqiel's Queen; Armaros, could ambush her. Flight: Being a Fallen Angel, Baraqiel can fly using his wings.

Raynare was an attractive young woman with violet eyes, and a curvaceous, slender body. She had long, silky black hair that reached down to her wide plumped hips and possessed two black feathered wings characteristic of her race. Age 19 Raynare's height is 164 cm. (5'4"), according to the visual book with her data. Her attire consisted of a short black dress with a small, light purple jacket on top, which was worn throughout most of her appearances in both the light novel and manga. In the anime, she had a slender body with a large bust. Her initial attire (as Yuuma) was her school uniform, which consisted of a dark red jacket with the letter "P" embroidered in gold, a white undershirt, a red bow, and a green skirt with a thin white strip around the lower end. Upon the climax of her date with Issei, she shredded her clothing and changed into her alternate (and more common) form. In the process of transforming, she grew taller, taking on a more mature appearance, and her eyes changed, taking on a darker, narrower, and more evil look. Her clothing also changed dramatically, now consisting of black, strap-like objects (resembling leather) around and under her breasts, a thong-like piece held around her hips by three thin straps, gloves that ran right up her arms with small lengths of chains hanging from them, shoulder guard-like objects on her shoulders with three large spikes sprouting from her right shoulder, and black thigh-high heeled boots. Her voice also dropped to a lower pitch when in this form. This form is best described as a very erotic and revealing version of her disguise. Personality Raynare seemed like a sweet young school girl at first, but this was just a disguise to hide her true nature. Her true personality revealed that she was vicious, petty, sadistic, treacherous, vindictive, arrogant, cruel, barbaric, and very deceptive. This was most infamously shown when she successfully manipulated Issei Hyoudou's mind in order to get close to him and kill him. She also laughed cruelly at Issei, believing him to be "weak" and that it would be "a waste of her time killing him". This shows how Fallen Angels like her can manipulate the will of mere humans with ease. She is loyal to her superiors, Azazel and Shemhazai, and would go to great lengths for them. However her loyalty may come into question as she tends to take action without their consent, believing it's for the good of all Fallen Angels. She has often shown overconfidence and tends to look down anyone who is (in her mind) inferior to her, as well as torment and taunt them, such as when she mocks Asia's death in front of Issei out of spite and shows no remorse. Not much was known about Raynare's history, other than the fact that she was banished from Heaven for an offense of some sort. Shortly before the series began, Raynare came into contact with Freed and Asia, who became her subordinates. She was sent to eliminate Issei because of his Sacred Gear's dangerous potential. Then Raynare secretly gathered and led an independent group of Fallen Angels and Exorcists who assisted her in attempting to steal Asia's Sacred Gear; Twilight Healing, believing she was better suited for its powers, and could thus better serve her leaders. Powers & Abilities Light Power: As a Fallen Angel, Raynare has the ability to use Light Power to create various effects. Raynare claims that, while not flashy, her light is particularly lethal to Devils for her level, enough that it wouldn't be strange for Low-class Devils to die from blows to the legs by her spears, and that even Middle-class Devils would have a hard time healing from the wounds. Issei stated that it felt like his bones and muscles were "melting," even after he removed the weapon itself. Light-Based Weapons: Raynare could create and throw spears of light to kill Devils. However, unlike most Fallen Angels who wield only one light spear, Raynare was skilled enough to create several light spears at once. She could put enough power behind them to pierce the body of a Rook-promoted Low-class Devil such as Issei, who demonstrated enough durability to easily withstand bullets of light in that state not long before. Magic: She is shown to be at least knowledgeable in some magic. Memory Alteration: Raynare was also able to wipe the memories and all the records of her existence as Yuuma from all the students she has met with at Kuoh Academy. Cloth Manipulation: She has shown to change between her casual clothing and her revealing black leather attire.[note 1] Flight: Being a Fallen Angel, Raynare could fly using her wings. Enhanced Durability: Raynare took a boosted blow from an enraged, Rook-promoted (albeit pre-training) Issei, and while knocked unconscious, was easily reawakened not long after seemingly without any serious injuries. Enhanced Speed: Raynare was repeatedly able to gore Issei with her spears before he could react & at speeds he didn't notice her firing off the shot, before & after he became a devil. Equipment Twilight Healing (Temporary): After performing the ritual to extract Twilight Healing from Asia, Raynare gained her Sacred Gear thus allowing her to heal herself. After being defeated by Issei and killed by Rias, the Twilight Healing is retrieved by Rias and returned to Asia.

Kalawarna was a Fallen Angel who allied herself with Raynare in her plot to steal Asia Argento's Sacred Gear. Kalawarna was a tall and buxom woman with brown eyes and long, navy blue hair that obscured her right eye. Age 21 Her attire consisted of a maroon, trenchcoat-like top with a wide collar, a matching miniskirt, and black heeled shoes. The trenchcoat top was open at her chest, giving view to her breasts and cleavage. She also wore a gold necklace around her neck. She appears to wear a white shirt underneath her top, but it can only be seen from the bottom. Personality Kalawarna was shown to be an arrogant and no-nonsense woman with a tendency to look down on her opponents. She is quite sadistic and shows no mercy towards her opponents. She also appears to be quite loyal to their leader, Azazel. She is also a cruel and manipulative cynic. History Not much was known about Kalawarna, other than the fact that she sided with Raynare in her plot to steal Asia's Sacred Gear. Light-Based Weapons: Kalawarna can create and throw light spears to kill Devils. Flight: Being a Fallen Angel, Kalawarna can fly using her wings.

Dohnaseek was a Fallen Angel allied with Raynare in the latter's plot to steal Asia Argento's Sacred Gear Dohnaseek was a middle-aged-looking man with short black hair and dark blue eyes[2]. His attire consisted of a pale gray trench coat over a white dress shirt with a matching ascot, black pants and shoes, a pair of black gloves, and a black fedora. Personality Dohnaseek was shown to be somewhat of a battle maniac In the anime, Dohnaseek was shown to be somewhat arrogant, looking down on both Rias and Akeno who came to confront him and his allies History Not much was known about Dohnaseek, other than the fact that he sided with Raynare in her plot to steal Asia's Sacred Gear Light-Based Weapons: Dohnaseek could generate and throw light spears to kill Devils Flight: Being a Fallen Angel, Dohnaseek could fly using his wings Age 29

Mittelt was a Fallen Angel who allied herself with Raynare in her plot to steal Asia Argento's Sacred Gear Mittelt was a girl with blonde hair which was styled into twin-tails and blue eyes. Age 13 She wore a Gothic Lolita attire, which consisted of a black dress with white frills, a large black bow on the front, and a green jewel embedded on the collar, white thigh-high socks with suspender garters, black set of frilly panties, and black shoes. She also wore a large black bow on top of her hair Despite her intricate design, she is only mentioned in the light novel by name three times and is never present in a scene. Similar to the other two fallen angels aligned to Raynare , her introduction, role, and exit is not described at all. Personality Mittelt seemed to be a joyful, upbeat girl at first glance but in reality she was playfully cruel, spiteful, and cynical This is shown from the fact that she felt no hesitation on trolling her opponents. This shows when she is confronted by Rias and Akeno who proceeds to call her bratty and annoying. History Not much is known about Mittelt, other than the fact that she sided with Raynare in her plot to steal Asia's Sacred Gear. Light-Based Weapons: Mittelt could create and throw light spears capable of killing devils. Flight: Being a Fallen Angel, Mittelt could fly using her wings

Irina Shidou (紫藤 イリナしどう イリナ, Shidō Irina) is one of the many female protagonists of High School DxD and the childhood friend of Issei Hyoudou. Age 18 Irina is a third-year high school student at Kuoh Academy in Class 3-B and is a devout Christian who, even after learning of God's death, still follows his teachings. She is later reincarnated as an Angel by the Archangel Michael, through one of the Brave Saints, her ranking among his peerage being "Ace Of Spades". She is also one of Issei's fiancées. Irina is a beautiful young woman with violet eyes. She has long chestnut hair that is usually tied into twintails, each held with a blue scrunchy, but on some occasions, she lets her hair down. Her body measurements are B87-W59-H89 cm [B34-W23-H35 in]; height is 164 cm (5 feet 4 inches) and body weight is 56 kg. She wears the standard Church battle attire, same as Xenovia's with some slight differences. After transferring to Kuoh Academy and moving into the Hyoudou Residence, she starts wearing the Kuoh Academy girls' school uniform, with black short shorts under her skirt and the addition of white sneakers with blue accents. Following her Angelization by Michael, she wears a red "A" printed on her right hand, symbolizing her position as Michael's Ace. Irina also gained white Angel wings and a halo, as of Volume 17, she has a total of 4 wings. Personality Irina is a cheerful, carefree, upbeat, and enthusiastic person. She is also shown to be cooperative and open-minded to others as she is seen with Arthur Pendragon discussing Excalibur Ruler, although he stated that the location is secret. She is a fiercely devout Christian, even more so than Xenovia, showing great respect for God's teachings. During her first appearance, she was very harsh towards those whom she perceived as an opposition to her religion. This was demonstrated by how she and Xenovia treated Asia Argento when they first met, as well as her reaction to Xenovia becoming a Devil. The death of God of the Bible was a great shock for Irina, yet she still believes in his teachings and transferred her belief to Michael who is the current "God". Irina later became close friends with Asia and the rest of the Occult Research Club members, even joining the ORC herself. As noted by Michael, in addition to her strong Christian faith, Irina is innocent, honest, respectful, and friendly, the traits which he valued and also the reason he chose her to be his Ace. Irina began experiencing "impure thoughts" around Issei; her Angel wings start to flicker from white to black indicating that she is about to "fall" from her status as a true Angel to a Fallen Angel if she gives in to her desires. She is shown to be very sensitive to and annoyed about being called "self-proclaiming". After kissing Issei, she becomes bolder in her relationship with him, as she becomes slightly less concerned about "falling" in order to show her love for him. This has also caused her to become perverted herself, as she has no qualms by being with Issei, even desiring to have sex with him. Irina's family lineage is related to the church, and her father being a pastor and exorcist of the Protestant Church and possessing a currently unidentified Holy Sword.[1] She is Issei's childhood friend who was under the impression that she was a boy, due to appearing quite tomboyish, and they were close friends who used to play together. At some point, she kissed him while he was sleeping at her house. She later left Japan and went to England with her family, due to her father's job, where she trained to become an exorcist of the Protestant Church. Three years prior at age 14, Irina was granted the ability to wield Holy Swords via a Holy Element and was given Excalibur Mimic, thus following in her father's footsteps. Soon after, she was eventually partnered with Xenovia, where they undertook a mission to slay the stray Vampire from the House of Manthar. At some point in time, she crossed blades with a knight from Riser Phenex's Peerage named Karlamine Light Power: As an Angel, Irina has the ability to use Light Powers to create various effects. Light-Based Weapons: As an Angel, Irina is able to create Light-based weapons such as Light Swords. In the anime, she has shown to be able to use light halos that wrapped about her foes of remarkable power and size such as one of Fenrir's sons. In Volume DX.4, Irina created a move, which creates rings of light that homes in on her opponents and radiates light. In Volume 25, she made a whip of light that imitates Excalibur Mimic. Artificial Holy Sword Wielder: After taking in the Light Container, Irina became an artificial Holy Sword user, being able to wield Excalibur Mimic and later Hauteclere. Enhanced Speed: While she can't match up to the likes of Yuuto Kiba, Irina is still noticeably fast due to her training as an Exorcist as she dodged Jeanne's attacks with ease. Enhanced Luck: Due to also receiving Ophis' blessing, Irina gained improved luck, gaining second place in a lottery. Master Swordswoman: Like Xenovia, Irina is well versed in swordsmanship, specialized in tricky movements that makes use of her speed, being able to fight on par with Jeanne during their first encounter. By Volume 19, Irina's swordsmanship skills became great enough being able to keep up against Ewald Cristaldi wielding a replica of Excalibur. Tomoe Meguri admitted that Irina's swordsmanship is on a whole different level.

Michael is the former leader of the Angels and Seraphs before Gabriel took over. He is one of the God of the Bible's creations, who took his place as leader after he died in the Great War. His current goals are to recreate the lost members of Heaven (mainly the Seraphim) and guide the Church with God's teachings. Upon the implementation of the Brave Saints system, he became King of the Suit of Spades ♠. Age 1000+ Michael has the appearance of a handsome-looking man with long blond hair and green eyes. Like Azazel, he has twelve wings growing from his back, and unlike other Angels whose wings are white, his wings are colored gold, further symbolizing his position as the former leader. He wears a red robe with a gold cross on the front of his white alb. He has golden shoulder plates with a white sash and a golden halo set above his head In the anime, his eyes are shaped in a perpetually sad manner even when genuinely angered or happy. Personality As leader of the Angels, Michael in his few appearances has shown to be extremely kind and compassionate. However, he will put the good of the many above the good of the few, as shown when he allowed Asia to be banished in order to preserve the religious faith of the Christian people and not risk the safety of Heaven. Michael is extremely loyal to his creator the God of the Bible. After his death, Michael did everything he could to maintain the religion of Christianity, leading the Angels and guiding the Church. He is even willing to be allied with the Angel's former enemies of Fallen Angels and Devils to ensure the Angels survival as a species. Despite being an Angel, Michael lacks any of the prejudice and bigotry that a lot of Angels bear towards Devils and Fallen Angels due to his immense kindness, and is perfectly willing to show kindness to or even befriend them. This is shown in his first interaction with Issei, where he showed courtesy and politeness. Despite his kindness, Michael can be merciless towards evil people like Rizevim as shown when Michael outright stated to Rizevim he will show no mercy. History One of the first creation and right-hand man of the Biblical God, Michael served as the leader of the Angels and assisted the Biblical God in the Great War against the Devils and Fallen Angels. After God died in the Great War, the Angels were forced to retreat as Michael and the other Seraphs try to activate the Heavens' system and were successful in activating it with Michael as the center as he takes over the place of his Creator as the supervisor of the Heavens' system. Powers & Abilities Immense Light Power: As a Angel, Michael has the ability to use light to create various effects. As one of the Four Great Seraph, more so the Archangel, his light powers are superior to that of others, even among the Seraph. Light-Based Weapons: Being an Angel, Michael is able to form various weapons and attacks from light. Michael's ability in creating and using weapons of light is vastly superior to regular Angels, able to quickly create a gigantic spear of light as shown when he attacked Rizevim. Immense Strength: As the former leader of the Seraphs and Angels, and the only Archangel along with being the only Angel with twelve golden wings, Michael is the strongest Angel and likely wields power equivalent to a Satan-Class Devil. Master Magician: Michael has expert knowledge when it comes to various kind of magic spells common to those of holy and angelic magics and rune symbols. Defensive Magic: Michael can create very powerful barriers that protect Team DxD from his own light attacks directed at Rizevim. Flight: Being an Angel, Michael can use his twelve golden wings to fly. Equipment Holy System: Michael's true power, however, comes from the fact that he is now the one in control of the system created by God in the distant past, which is what causes harm to Devils who come into contact with blessed objects, provides miracles, and determines who can be saved. Unfortunately, with Michael in charge, the system is vastly inferior to how it was with God running it. However, since entering the Isolation Barrier Field, this was transferred over to Gabriel.

Age “unknown” Ophis is the Dragon God who represents Infinity, Chaos, and Nothingness, known as the Ouroboros Dragon and the Infinite Dragon God. She is one of the most powerful Dragons and beings in existence, aside from Great Red. Ophis was the Khaos Brigade's figurehead, before the betrayal of the Hero Faction, where she lost a portion of her power because of Samael, which would later birth Lilith.[1] Afterwards, she started living inside of the Hyoudou Residence with the others as the group's friend and supporter. Ophis' current appearance is that of a cute young girl with long black hair down to her hips and black eyes (gray in the anime). Her ears differ from a normal human's as they have pointed tips, although her long black hair makes this feature difficult to notice. Her dark grey eyes have reptilian slitted pupils. Azazel stated that Ophis had the appearance of an old man in the past before changing it. Her body measurements are [B66-W53-H70]; height is [137 cm] and body weight is [31 kg]. Her attire consists of a black Gothic Lolita fashion. However, Ophis is a true shapeshifter, able to freely manipulate her body shape and size to assume any form that she chooses, regardless of her age, race, or gender. Unlike the other Dragons that have large reptilian-like bodies, Ophis is a humanoid-shaped Dragon.[2] Personality Born from nothingness, Ophis has little-to-no emotions, to the point of being viewed as apathetic. Her sole desire was to return to the Dimensional Gap, and reobtain "silence" through getting rid of Great Red, who she has shown the most, if the slightest aggression towards. Outside of that, Ophis doesn't care about the people or things around her; helping the Khaos Brigade as long as they helped her. Despite her superior powers, Ophis never boasts about it; however, Ophis didn't kill Cao Cao despite his betrayal, because she could kill him whenever she wanted. Over time, Azazel indicated that Ophis changed due to spending time around and interacting with the Human World, which later started being shown. Issei himself stated that she was a pure and honest dragon, her powers caused people to fear her and tricked into leading the Khaos Brigade.[3] After befriending Issei, she abandoned the Khaos Brigade and her original goals. Her deep naiveté caused her to act childish, often mimicking the actions that catches her attention and often wanders off to anything she finds interesting. Ophis is also honest, while coming off as rude, to the point of being brutal without being aware about it; as noted when she described Koneko as "Cat" and Ravel as "Bird".[4] Another time was when she had commented she was stronger than Michael, after Irina questioned whether or not it was fine to pray to her.[5] Whenever she is asked a question she seems to take interest in, she goes into "? Mode" which is where she goes into deep thought about the question asked. Ophis loves eating sweets (a trait passed down to Lilith) as well as bananas. History Sometime in the distant past, Ophis was born in the Dimensional Gap and lived there as its home. Eventually, long ago, Ophis left the Gap, but when she attempted to return, she found that the Great Red had taken up residence there. Before assuming her current form, she used a different guise in the form of an elderly man. At some point before the start of the series, Ophis became the leader of the Khaos Brigade. Powers & Abilities Immense Strength: As a Dragon God, Ophis is the strongest being in the world not counting Great Red,[6] exceeding the Heavenly Dragons in their prime combined, with Ddraig stating her power is infinite. In fact, despite losing a large portion of her power due to Samael and becoming “finite”, it was stated that she was still twice as strong as Ddraig and Albion, with her stating that she felt "weak" despite that level of power. Since losing her original strength, her powers became unstable, releasing destructive power that had annihilated everything. A normal slap from Ophis can cause destructive results, sending a yeti flying and causing Nurarihyon great pain after slapping his butt. Ophis in her prime would be equivalent to the likes of Great Red and Trihexa. It is stated that if Ophis and Lilith fight together, they can access all of Ophis' former power; with their power being infinite.[7] Immense Durability: Being an existence with the power of infinity, Ophis' durability borders on the point of near absolute invulnerability as shown when Ophis was stabbed by the True Longinus, an immensely powerful Sacred Gear capable of slaying Gods, and was completely unaffected when Issei stated that Ophis did not even shed blood. Even after being engulfed in Samael's extremely deadly Dragon Slayer poison for several minutes, Ophis was seemingly only disabled and left vulnerable to having her power stolen, emerging from the ultimate dragon slayer's grasp without any apparent injury; contrary to Vali who managed to survive due to his vast demonic power, but had to withstand tremendous pain from the poison until he was cured by Sun Wukong, and Issei who has extremely tenacious durability, was ultimately killed by the same poison. Shapeshifting: Ophis is a true shapeshifter, able to alter her size, apparent age, physical attributes and characteristics, and even her apparent gender. She can also perfectly recreate the voice of any person. Blessing: Similar to other gods, Ophis can 'bless' people, granting them certain advantages and abilities, having no negative effects on Devils. Her blessings made Asia more compatible with Dragons; increased Irina's luck; in addition to letting others tap into their potential, as Issei tapped into the infinite power he gained, while Vali could tap into Lucifer's and Albion's powers. Telepathy: Ophis can sometimes communicate through the minds of others, doing so during Issei's battle with the Emperor Diehauser Belial and Rizevim Lucifer. During this ordeal, she also mentally chanted alongside Issei and Ddraig to activate the Diabolos Dragon form, despite being unconscious at the time from Niðhöggr's assault. Flight: As a dragon, Ophis can fly, but unlike other dragons who use their wings to do so, Ophis can simply float in midair without effort.

Age “unknown” Great Red also known as the Apocalypse Dragon, the True Red Dragon God Emperor, True Dragon, and the Dragon of Dragons, was a powerful Dragon that resided in the Dimensional Gap. It was the dragon recorded in the Apocalypse. Great Red was a massive red Western Dragon with a horn on his snout and has two sets of wings. His overall length measures around 100 meters. He is the third-largest Dragon in the series, after Midgardsormr and Apophis. Personality Not much could be deduced on Great Red's personality, but Issei compared his personality to that of a biker gang delinquent, claiming that Great Red travelled around the Dimensional Gap doing crazy moves and got aggravated at people that were staring at him. History Similar to Ophis, Great Red was born in the Dimensional Gap from the "illusions" of "dreams". Not much is known aside from the fact that he soon took refuge there once Ophis left, becoming the counterstone maintaining that space since she changed from interacting with the Human World. Sometime before the series, Great Red was challenged by the then sixth Dragon King, Tannin, but ignored him. Powers & Abilities Dream Manipulation: As the God of Dreams, Great Red represents dreams in the past, present and future.[1] He was able to respond to Issei's strong wish to return home by responding to his dream and appearing before him, as well as reflecting the feelings of the children in the Underworld to Issei in the Dimensional Gap. Immense Strength: As a Dragon God, Great Red possess tremendous power, making him the most powerful of all dragon-kind alongside Ophis. His strength surpasses that of even the Two Heavenly Dragons, Gods from the various factions such as the Biblical God, even ignoring Tannin, an Ultimate-Class Devil and former Dragon King. A mere portion of his power, which was lent to Issei was enough to eliminate the Jabberwocky, a creature that allied forces led by Diehauser and Sirzechs' Peerage, all of which are considered monsters had trouble with, and erased a portion of the Underworld. Great Red is one of the lone beings who could rival Ophis, the Ouroboros Dragon before losing her powers, being equivalent or superior to Trihexa after getting serious, and a clash between them would destroy the world. Ryuuteimaru, who had manifested a portion of his powers by using AxA has enough strength to destroy an entire planet. Despite losing against him, Great Red proved a suitable challenge in battle against Regalzeva, the Fierce God of Evie Etoulde. Immense Durability: Like Ophis, being an existence of dreams, it can also be assumed that Great Red was nigh-invulnerable. This was further proven as Ophis herself didn't confront Great Red himself after he took refuge in the Dimensional Gap, then accepted help from the Khaos Brigade consisting of three High-Tier Longinus users and one Mid-Tier Longinus user, while Rizevim; a Super Devil, needed to awaken Trihexa in order to kill him. This doesn't mean that Great Red wasn't unaffected by everything, as a being such as the Dragon Eater could affect him; he, in fact, was effortlessly killed by Regalzeva, the Fierce God of Evie Etoulde. Body Creation: Great Red could create biological bodies, which are in perfect condition for others to inhabit, such as the case with Issei being given a new body made from his flesh. He was able to fuse with those who were made from his flesh like with Issei, resulting in the "Super Gigantic Balance Breaker", which was used to fight against the Jabberwocky. Flight: As a Dragon, Great Red could use its colossal wings to fly.

Age 10,000+ Ddraig is one of the Two Heavenly Dragons and the arch-rival of Albion. He is called the Red Dragon known as the Welsh Dragon, Y Ddraig Goch, Red Dragon Emperor (赤龍帝, Sekiryūtei) and Red Dragon Emperor of Domination, who resides within the Longinus, Boosted Gear, wielded by Issei Hyoudou. Ddraig is feared among the Angels, Fallen Angels, Devils and the various other factions in the world for his destructive powers, which are said to be able to kill both Gods and Satans. Ddraig is a dragon with the appearance of a large red Western Dragon, with a long neck and green eyes (described as red in Volume 2). He also has red and golden spikes throughout his body. Personality Ddraig's personality has changed a great deal as time has passed. At first, he had a great deal of pride in himself, though he admits that he had an intense rivalry with Albion, the other Heavenly Dragon. Since that time, he has become somewhat depressed because of the fact that he has become known as the Oppai Dragon and the Breast Dragon Emperor. Ddraig even requires counseling and medication because of it. Ddraig has shown that he cares a great deal about his current host, Issei, as much as Albion cares about Vali, despite the fact that their hosts are the ones responsible for their demeaning nicknames. He has also shown that he really likes his current lifestyle, which doesn't involve fighting his rival every time they meet, but knows that there will eventually be a time when he and Issei must fight Albion and Vali. It also noted that he has an extremely high level of intelligence and is also wise enough to give advice to others especially to Issei, as he can tell all things about mythological things just like Azazel. Although he and Albion are powerful enough to challenge Gods and Satans, they both agreed to avoid fighting Evil Dragons, claiming that they are more brutal than other dragons. In the past, Ddraig was a fearsome Dragon known to have powerful flames that can incinerate anything, including Gods, and will never go out till they burn the opponents to ashes. Ddraig eventually met Albion, who was immune to his flames. Happy to meet someone who can rival him, Ddraig sealed his flames and started to compete with Albion to improve themselves, developing techniques such as Boost and Penetrate, and both eventually became famous as the Two Heavenly Dragons. During their many battles to improve themselves, both the Heavenly Dragons rampaged in the Realm of the Dead. Ddraig also fought against Grendel and Níðhöggr at an undisclosed time in the past. Before the start of the Great War, Ddraig had borrowed some of Tiamat's legendary treasures for his upcoming battle with Albion. At one point, while continuing his battle with his arch-rival, the Vanishing Dragon, Albion, which was interrupted by the Angels, Devils, and Fallen Angels who were at war during the time. In anger, both Dragons attacked the leaders of the Three Factions, which led to their bodies being destroyed and their souls being sealed into two separate Sacred Gears, with Ddraig being placed inside the Longinus Sacred Gear; Boosted Gear. Tiamat's borrowed treasure was left to be stolen by Human thieves after being sealed and scattered them all across the Human World. Since then, she has been chasing after Ddraig and his hosts for a long time in order to retrieve her stolen treasure; however Ddraig always detected her presence and asked his hosts to run away. This was because he could not return her treasures and felt that he would be chased for it. Immense Strength: As one of the Heavenly Dragons, Ddraig has immense power, surpassing the Dragon Kings, the Four Great Satans and God himself, and is surpassed only by the Dragon Gods. Azazel stated he'd surpassed the three strongest Evil Dragons, even Crom Cruach before his training. It took the Three Factions allying together to kill the Heavenly Dragons, both of whom would've been among the Top 10 Strongest Beings. Once resurrected, his strength overpowered Apollon, defeated Typhon, then fought Crom Cruach, who is said to have surpassed Ddraig. He then fought and overwhelmed the Fake Albion, who was said to be above Dragon King. Immense Durability: In Volume 25, Typhon's powerful lightning storm was unable to inflict any damage at all. Ddraig was also able to repel Apollon's light just by wrapping himself in his aura and flapping his wings. Ddraig also endured Crom's vicious and powerful attacks, even though the Evil Dragon is said to have become stronger than him. Doubling and Transference, fire breathing Welsh Dragon Flare (ウェルシュ・ドラゴン・フレア, U~erushu Doragon Furea): A technique which he developed after observing his current host, Issei, where he breaths out a massive amount of flames able to cover an entire island. Dragon Aura: Ddraig can release a tremendous and dense Dragon aura, befitting a Heavenly Dragon, one that is much stronger than Issei's Diabolos Dragon, making the air around him feel cold from the presence alone, & can be raised even higher via Boost and telepath.

Age 10,000+ Albion is one of the Two Heavenly Dragons and the arch-rival of Ddraig. He is called the White Dragon, also known as the Vanishing Dragon, Albion Gwiber, White Dragon Emperor (白龍皇, Hakuryūkō) and White Dragon Emperor of Supremacy. He is currently residing within the Longinus, Divine Dividing, wielded by Vali Lucifer. Like Ddraig, he is also feared among Angels, Fallen Angels, Devils and the various factions in the world for his destructive powers, which are said to be able to kill both Gods and Satans. Albion is an enormous white western dragon described as having a beautiful pure white body, he has blue eyes, two golden horns, and unlike most western dragons, he has feathered wings. Personality Albion's personality has changed a great deal as time has passed. In the past, he felt lonely as a result of his poison and immense power, as no one wanted to come and challenge him. This changed as he met Ddraig, whose intense rivalry inspired him to become "a brave and fearless dragon on par with him." In the modern day, he has become somewhat depressed over the fact that he has become known as the Butt Dragon Emperor. As of Volume 15, it has been revealed that like Ddraig, he also needs a counselor because of the Butt Dragon Emperor related things. Nevertheless, he has shown that he cares a great deal about his current host, Vali, as much as Ddraig cares about Issei, despite the fact that their hosts are the ones responsible for their demeaning nicknames. Although he and Ddraig are powerful enough to challenge Gods and Satans, they both agreed to avoid fighting Evil Dragons, claiming that they are more brutal than other dragons. He has also shown that he really likes his current lifestyle, which doesn't involve fighting his rival every time they meet, but knows that there will eventually be a time when he and Vali must fight Ddraig and Issei.In the past, being known as Gwiber, Albion was an invincible Dragon and was notably feared for his venomous ability which can even kill Gods easily, and due to this fearful power, he was always lonely and resented using it. Although being overwhelmingly powerful, Albion was depressed due to having no equal to stand up against him until he met his soon to be arch-rival: the Welsh Dragon Ddraig, a being who was immune to his venom. Excited at the fact that there was an entity that could rival his power, Albion sealed his poison and soon resorted to becoming stronger through his rival, eventually developing techniques such as Divide and Reflect and both eventually became known as the Two Heavenly Dragons. During their many battles to improve themselves, both the Heavenly Dragons rampaged in the Realm of the Dead. At one point in their heated rivalry, while Albion was fighting Ddraig, their battle was interrupted by the Angels, Devils, and Fallen Angels who were at war during the time. In anger, both Dragons attacked the leaders of the Three Factions, which led to their bodies being destroyed and their souls being sealed into two separate Sacred Gears, with Albion being placed inside the Sacred Gear, Divine Dividing. Reduce (減少, Genshō): Albion's original ability. He has a unique blend of venom that is capable of reducing the existence of all organic matter, including Gods. Even their souls are cut down bit by bit. However, this is ineffective against Great Red, Ophis, and Ddraig. Division and Absorption (半減と吸収, Hangen to Kyūshū): A power he developed as he battled Ddraig over the course of their rivalry, Albion is famed for his ability to divide an opponent's strength and absorb that halved power to add to his own.

Sun Wukong and Vasco still consider his views and abilities to be amateurish, childish, lacking, and still have some development. His cockiness would be his greatest downfall, according to Vali, as he refuses to kill both Issei and Vali, and put his objectives first rather than them at that time, thus allowing Issei to defeat him during their third encounter. But still, has some respect for those he deems worthy, those that manage to get his interest and he considers strong, such as Issei, Azazel, Vali, and Vasco. Like Georg, he tends to overthink things if some things do not tend to happen, the way he expects them to be, as is seen when he overthinks Issei's survival with the help of Great Red and Ophis. He also believes in fate, where he believes that there is a reason why he met Issei, Vali, and other various strong people who exist. It extended to the point that he mentioned in Volume 18, that the reason why he returned is that he wants to know why the True Longinus was given to him and why it chose him despite his past mistakes. During his return in Volume 18, he is shown as willing to cooperate with the DxD against Qlippoth and during the Evil Dragon war, where he is shown helping various people including the last stand against Trihexa and the Evil Dragons as Indra's order, and align himself with the Grigori as its agent along with Tobio. Immense Speed: Cao Cao has shown incredible speed, greater than even well trained humans, matching Azazel in his Downfall Dragon Another Armor. Another testament to his speed was when he fended off the combined assault of Vali and Azazel in their respective Balance Breaker armors without being hit once. In conjunction with his gifted senses, Cao Cao can timely evaded attacks that are hard to avoid, such as Sairaorg 's Breakdown the Beast enhanced speed and Sonnelion's Crushing demonic power. Immense Durability: While his durability is inferior to Issei's and Vali's, Cao Cao has shown great tolerance to damage and pain, having an arm chopped off by Issei's Ascalon only to calmly retrieve it and restore it back with a Phoenix Tear, as well as surviving a punch from Triaina Rook by blocking with the True Longinus, with the impact of his fall breaking the ground. Later on, he was able to survive the fatal pain of having his Medusa's eye destroyed by Samael's curse. In Volume DX.4, Cao Cao was able to withstand a punch from Sairaorg Bael in his Breakdown the Beast by blocking with his spear, albeit Sairaorg himself was in a grievously injured state.

As the holiest relic, believers can be driven insane looking at it, and vaporize High-Class Devils and also damage Satan-Class Devils. Despite being a spear, it can release powerful light blasts and wrap its aura around its blast; extend and retract based on his will; and shield himself from attacks from even Issei and Sairaorg. Polar Night Longinus Chakravartin (極夜なる天輪聖王の輝廻槍ポーラーナイト・ロンギヌス・チャクラヴァルティン, Pōrā Naito Ronginusu Chakuravarutin): Cao Cao's Sub-Species Balance Breaker, which creates a light halo behind him and seven identical orbs, the Seven Treasures that has different abilities; making it difficult to tell the difference between them. The orbs can move based on his will and turn into spears to attack, and penetrate Ladon's barrier. Instead of summoning his Seven Treasures, Cao Cao can concentrate Polar Night Longinus Chakravatin's power into solely strengthen his True Longinus's offensive power, making it possible to pierce Sairaorg's beast armor and damage him. Hatthiratana (象宝ハッティラタナ, Hattiratana): It grants the wielder to levitate an object the sphere touches. It also is shown that Cao Cao has the ability to fly and was able to lift Ladon into the air.

It seems to have some sort of restriction on how often it can be used. Issei speculated that it needs some sort of requirement for activation.

It can repel a great number of mass-produced Evil Dragons and cause immense pain to Apophis, an immensely powerful Evil Dragon. Medusa's Eye: After he lost his right eye to Issei's attack, and later replaces the lost eye with Medusa's eye, letting him turn anything to stone. Cao Cao lost the Medusa's eye when Issei used Samael's curse on it. Artificial Eye: At some point, Cao Cao received an artificial eye to replace the one he lost, then Medusa's Eye. It was revealed in their fight against Surtr, Rias theorized it has some special power.

After his defeat against Gasper Vladi in Volume 12, Georg lost an eye, an arm, and his left leg is also damaged and colored in black. Personality Georg appears to be highly loyal to Cao Cao as he was following his orders and when he saved the latter following his defeat against Issei. Georg mentioned that his ancestor is so great it puts so much pressure on him. It is shown that Georg can become concerned about the strength of his opponents just like he witnessed Heracles's defeat at the hands of Sairaorg, stating that the Gremory group was growing fast and irregularly. He was shown to be somewhat of a coward when he found out that neither his Sacred Gear or magic couldn't do something against Gasper's darkness and tried to escape as fast as possible. Master Magician: Georg is said to be a high-level Magician capable of a diverse array of spells. He was able to use Le Fay's swapping teleportation magic technique from seeing it only once.

Age 19 Siegfried was a member of the Hero Faction. He was one of the top two swordsmen of the Khaos Brigade alongside Arthur Pendragon of the Vali Team and was known as The Demonic Sword User and "Chaos Edge" Sieg. Siegfried was a handsome young man with silver-white hair and red eyes. Issei even compared him to Yuuto saying he looks like a "white Kiba". He, just like other members of the Hero Faction, wore a gakuren, and on top of it, a priest's coat, similar to Freed Sellzen. He also wore a belt that held his five Demon Swords and a Light Sword, which were around his waist and legs, forming a sword skirt. Personality Little has been mentioned of Siegfried's personality besides the fact that he was a dedicated and analytic swordsman and the rival of Arthur Pendragon. He has also shown to have a little regard for his own life using five Demon Swords that cut down his lifespan with no regard when overused and enjoyed fighting against strong fellow swordsmen. He is also shown to have a bit of a frivolous atmosphere as he complimented Issei's breast techniques and stated that he did not wish to retreat back to his Hero Faction comrades without accomplishing anything due to not wanting to be mocked by the likes of Jeanne and Heracles. He can also be quite arrogant and cold, mocking the Gremory group for their weak attacks and fighting spirit in the wake of Issei's death (at the time). History Siegfried was created as a test-tube baby from multiple genetic patterns at the Sigurd Institution, who were trying to create the "True Descendant of Sigurd" who can use Gram by gathering those who carry his blood. The children of the institute are made from different patterns of genetics. The institute tried to make Sigurd's descendant artificially, to which Siegfried himself was artificially created. He was the only one to be able to handle Gram and was Lint Sellzen's teacher at some point. Natural-Born Demon Sword Wielder: Due to being made from genetics of the original Sigurd, he was able to wield Gram, the strongest demon sword; in addition to other four demon swords. Kiba noted that the reason that he couldn't use Gram to the fullest was due to his Twice Critical, due to its dragon attribute, and would need to inhibit one of them in order to fight. Master Swordsman: Siegfried was a former top warrior renowned among the Orthodox Church, soon becoming a master swordsman as renowned as Arthur among the Hero Faction; others stating the two are rivals. He fought a total of three other swordmasters of their own fight at the same time without getting serious.

In addition to this, through his Balance Breaker, he can perform a Six-Sword Style, letting him dominate Kiba and Xenovia at the same time, both fighting their hardest. Immense Speed: From his training as an exorcist, Siegfried is extremely fast. He can easily fight both Yuuto and Xenovia at the same time using just a minimal effort. Twice Critical (龍の手トゥワイス・クリティカル, Tuwaisu Kuritikaru): Siegfried's Sacred Gear. It is a sub-species, and instead of a gauntlet, it creates a silver Dragon Arm on Siegfried's back which doubles his power. As such, his Twice Critical functions as an additional arm, making it possible to use a Three-Sword Style. Demon Swords (魔剣, Maken): Siegfried owns a total of five legendary Demon Sword, and often wielded them all at the same time when activating his Balance Breaker. However, starting with Gram, the other four chose Kiba after his death. Gram: Known as the Demonic Emperor Sword, is a legendary demonic sword used by the original Sigurd with the same properties as Ascalon and Durandal, unlike the latter it doesn't need to charge up to release its destructive aura, thus making it much stronger than it. Gram was the first out of all his demon swords to reject Siegfried and chooses Yuuto as its new wielder. Balmung: A Demon Sword from Norse mythology with a drill-like aura. It is capable of creating powerful whirlwinds. Nothung: A Demon Sword that specializes in sharpness. Tyrfing: A Demon Sword that specializes in destruction. Dáinsleif: A Demon Sword that creates huge pillars of ice from the ground. Light Sword: Siegfried wields a Light sword in battle against devils, which completes his six sword style using his Chaos Edge Asura Ravage. Chaos Break: A special doping for Sacred Gear made from the blood of the original Satans, created by the Hero Faction with the help of the Old Satan Faction. It allows Siegfried to transform into a Spider-like form that enables his to wield Gram without suffering negative consequences from his using his Twice Critical along with Gram.

Personality Heracles is shown to be arrogant, overconfident, brutal, stubborn, assertive, and pugnacious. Heracles loves battles and takes great pride and confidence in his name and his skills. He often has a tendency to look down upon his opponents, as shown when he claimed that a "defect" like Sairaorg cannot possibly defeat him just because Sairaorg can't use any special demonic powers. He also has no qualms in employing dirty tricks to defeat his opponents like when he attacked a bus with children in it, all in order to defeat the Sitri group. However, after his defeat at the hands of Saioraorg Bael and his punishment of being forced to look after Devil kindergarden children, his personality had undergone a significant change. He lost his arrogance and other negative qualities as he became more determined to increase his own strength and win against Sairaorg in a fight to overcome his past defeat. But his most significant change in character was the fact that he started to care deeply about children after spending time protecting them and looking after them. This is seen in his match against Sairaorg, where Heracles was able to get up after being knocked down by Sairaorg after being cheered on by the Devil children as well as increasing his own power. Heracles is shown to often play with the various supernatural children such as the Youkai children in Kyoto by dressing up as characters from Oppai Dragon.

The aura around the wielder's body glows, transforming into numerous missile-like objects, ready for the wielder to discharge them towards its enemies at a moment's notice.

Lilith is a clone of Ophis created from her stolen powers in Volume 11, and is currently considered as Ophis by the Alliance and Khaos Brigade. Lilith appears identical to Ophis, with the exceptions of a slightly different outfit and a ponytail. It is unknown if she can shapeshift like Ophis. Personality Lilith rarely shows any sort of emotion, but she inherited Ophis' naive and innocent attitude, as well as her love for sweets. Azazel has noted that she is a rather greedy Dragon. Lilith often speaks in the third-person, and in a childish, simplistic manner. History Lilith was created by Khaos Brigade some time after Ophis' powers were stolen by Cao Cao. She was then placed as the personal bodyguard of Rizevim Livan Lucifer, who named her after his mother, Lilith. Powers/Abilities Immense Strength: Lilith possesses immense strength, as she was made with 3/4ths of Ophis' power (give or take a relatively "small" amount Ophis managed to remove as she was being drained). Despite this pedigree, she was knocked aside by and incapable of slaying an Outraged Fafnir (in which state he's seemingly roughly comparable in attack power to a Heavenly Dragon, so still weaker than the current Ophis) with a single strike, implying she might not be able to use the full extent of that stolen might. She was able to take the full force attack of the Ex-Durandal with her bare hands and reflect the attack by simply putting her hand forward and swinging it to the side. Immense Durability: Like her origin Ophis, Lilith is extremely durable. She demonstrates this when she was completely unscathed after a strike from Fafnir in his Outrage Mode. Magic: Lilith is capable of using varieties of magic. Defensive Magic: Liltih is capable of creating magic barriers, though they were easily bitten through by Fafnir in his Outrage Mode.

The kimono features a white interior and it is open at her shoulders, giving view to her enormous breasts. Her hair was held back by a traditional hair ornament, with six golden bira kanzashi and several red kanzashi. In her real, vulpine form, she has the appearance of a giant nine-tailed fox with golden fur. Issei describe this form to be at least ten meters in height, and possibly bigger than Fenrir. Personality Yasaka is shown to be very humble and polite, as well as a loving mother and a dedicated leader. However, she also has a teasing and flirtatious side, as seen when she offered Issei the chance to have a child with her. Despite her flirty nature, she's seemingly unused to receiving gestures of affection, as she was briefly flustered by Issei's gift to her before recovering. History Not much is known about Yasaka, other than at some point before the arrival of Issei and the second-year students of Kuoh Academy, she was captured by the Hero Faction. Powers & Abilities Immense Strength: Yasaka is very powerful, and has been stated to be equal to an Ultimate-Class Devil and can fight on par with Vritra, one of the Dragon Kings. Yasaka was shown to be capable of fighting a Bandersnatch, as well as blow away a cluster of mass-produced Evil Dragons by herself. Fox Fire: Yasaka's fox fire gives off extreme heat that rivals that of Vritra's black flames and incinerate many mass-produced Evil Dragons. Transformation: Yasaka has the ability to change between her human form and her giant nine-tailed fox form. She is also able to sprout and hide her nine fox tails and ears whenever she chooses appear human in public. Youjutsu Master: Yasaka has great mastery of Youjutsu. With it, she is able to conjure various spells. Teleportation: Yasaka can use a teleportation magic circle to teleport to any location she wishes. Sunshower Barrier: After causing a sunshower, Yasaka can move multiple poeple, allies and enemies inside of an artificial space without causing harm to the outside world. However, a rushed barrier won't last long and can break from powerful beings such as Issei using Pseudo Dragon Deification. Equipment Kyoto’s Leyline: Being the Kyuubi who control Kyoto's leylines, Yasaka has access to all of the immense spiritual power flowing throughout it, which coupled with Georg's spells provided her with almost endless power, letting her compete with Vritra and Yu-Long. However, due to this trait, she cannot leave Kyoto for long and her death would destabilize the city.

Matsuda (松田まつだ) is one of Issei's best friends who makes up the "Perverted Trio", a trio of the biggest perverts at the Academy, and is a self-proclaimed lolicon. Matsuda's nicknames are "Perverted Baldy" (エロ坊主 Ero-bōzu) and "Sexual Harassment Paparazzi (セクハラパパラッチ Sekuhara Paparatchi). Matsuda has shaved hair and normally wears his Kuoh Academy uniform with an unbuttoned blazer. Matsuda is a former jock and school sports star back in junior high school where he broke multiple records, but he’s in the Photo-Club now. He is not ashamed in talking about perverted stuff or bringing out pornography even in public, he's also open about wanting to take photos of every part of the girls' bodies. Matsuda always seems to acquire exclusive high-rating pornography from some reliable sources that's normally difficult to get and shares them with his two friends. In True Volume 1, it's revealed that Matsuda had saved a girl named Hase from school who was being hit on, since then she likely developed a crush on him. Kiryuu helped to properly introduce her to him. As she spoke with him in private, it's possible they started dating

Motohama (元浜もとはま) is the other best friend of Issei who makes up the "Perverted Trio". Motohama has the ability to calculate a female's body measurements just by looking, which earned him nicknames such as "Perverted Glasses" (エロメガネ Ero-megane) and "Three Sizes Scouter" (スリーサイズスカウター Surī Saizu Sukautā). It's stated that he has a special body where his power level plummets down when he takes his glasses off. Motohama is known to have better academic results than both Issei and Matsuda and appears to be the most level headed of the trio as he tries to keep his cool even when committing perverted acts. In the anime, he states to have full data on every girl attending Kuoh Academy. He states Issei has stated to have attempted to copy his scouter ability but even with all his power he was unable to. By True Volume 1, Motohama was now the only one of the trio without a girl in his life, a fact he attempted to deny.

The light novel volume 1 named two of the girls: Murayama (村山むらやま) and Katase (片瀬かたせ), both of who are in the same class as the Perverted Trio and Church Trio. Like most of the girls in the school, they admire both Rias and Akeno, have a degree of romantic affection and attraction towards Yuuto, and dislike Issei. They also appear to be friends with Asia, know that she lives with Issei and warn her to be cautious of any possible perverted attempts he might make. According to Motohama in the anime: Murayama's body measurements are B84-W70-H81 cm. (B36-W22-H34 in.), Katase's body measurements are B78.5-W65-H79 cm. (B34-W22-H36 in.).

The "Perverted Trio" (変態三人組 Hentai San'nin-gumi) is a trio formed by the three most perverted students of Kuoh Academy who commit lecherous acts to the female students. Aside from Issei Hyoudou, the other members are Matsuda and Motohama, who are Issei's only friends outside of his supernatural life as they do not know that Issei and the Occult Research Club members are all supernatural beings, fearing they would be put in danger upon finding out. The three have known each other for a long time and enrolled into the academy together on their first year due to the large quantity of girls in the school. In the anime, the trio are all huge fans of an adult video actress named Momo Momozono, who portrays the tokusatsu heroine Kaben Rider Pinky

The Devils (悪魔, Akuma) are one of the Three Factions in High School DxD, alongside the Angels and Fallen Angels. There are two major types of Devils in the story: the Pure-Blooded Devils (純血悪魔, Junketsu Akuma), and Reincarnated Devils (転生悪魔, Tensei Akuma). Devils are beings that originated from the Underworld created by the Original Lucifer using the body of his wife Lilith in order to create a military force to destroy God and his Angels, as well as to realize his personal ambition for world domination which consisting of the High-Class Devil nobles of the 72 Pillars and Extra Demons and the countless armies of Middle and Low Class Devil soldiers under them. The total life span of a Devil is approximately 10,000 years. The Devils were originally ruled by the Four Great Satans prior to their death in the Great War. Following the end of the Great War, the descendants of the original Satans apart from Rizevim wanted to continue the Great War but were faced with opposition by other Devils, most prominently the Bael clan, who assumed authority after the death of their leaders. This started a Civil War between the Devils with the descendants of the original Satans losing the war and a new government was formed among the Devils. The new government then appoints four new Satans through strength and accomplishment in the civil war. A common weakness for all Devils is that they cannot go near/get involved with anything that has to do with the Biblical God, as they will suffer nasty side effects (headaches, immense pain, etc.), as seen when Issei couldn't go near the Church when he was talking to Asia, or when he tried to pray but only ended up collapsing from the pain soon after. They are vulnerable to holy objects such as crucifixes, holy water, and the Bible, and can get killed easily by Holy Swords and Sacred Gears with divine properties, such as Blade Blacksmith and the True Longinus (Asia's Twilight Healing, however, is a notable exception). These effects are caused by the system put in place by the Biblical God, which was being kept up by Michael and is now being kept up by Gabriel, and only she has the power to change the system.

All Devils have enhanced physical abilities such as superhuman strength, endurance, and enhanced sense such as sight and hearing; in addition to being able to see clearly in the dark as creatures of the night. Devils are able to fly through using their bat-like wings, which are capable of retracting into their backs as if disappearing entirely. They also possess a passive ability called "Language", which allows normal people listening to them to hear it in the language they're most familiar with and vice versa. According to Rias in Volume 4, Devils are also immune to being sunburned. In some cases some devils can have Ki or mana

The Underworld is roughly the same size as the Human world, but with a much larger landmass, as there are no oceans, just lakes.The sky was originally purple during both the day and night, but the current Four Great Satans adjusted the flow of time to match it in the human world for the sake of the reincarnated Devils. They reproduced an artificial moon using Demonic Power and made the night's darkness the same as the human world. The Underworld was originally split into two regions: The Devils' Region and the Fallen Angels' Region, which ended in Volume 4 after the creation of the peace treaty between the leaders of the Three Factions. Lucifaad The original Capital of the Underworld and the Satan territory ruled by the original Lucifer before the four New Satans took office as the second generation Satans. In the past, the children of the first Satans and their blood relatives lived there and at the Amphitheater, there was a “meeting between young Devils” which was attended by all of the 72 Pillars, but usually served as a way of the Satan descendants to show off their authority among the lower classes of Devils. It is also the place where Sirzechs Gremory defeated and killed Bidleid, thus ending the civil war in the final battle between the Satan and the Rebel army.

beings who serve the Biblical God, and have the powers to inflict pain upon Devils/demons and by extension the Fallen Angels, due to their light-based powers. After the death of the God of the Bible in the Great War of the Three Factions, the Angels were incapable of increasing their numbers normally until the creation of the Brave Saint system which allows humans to be reincarnated into Angels. Their power is derived from the faith of God's believers, so it was important for them to conceal God's death. During the peace conference of the Three Factions, Michael explained that the reason for Asia and Xenovia's excommunication from the Church was because of the possibility of them affecting humanity's faith in God which was necessary for the Angels' survival. Unlike Devils and Fallen Angels, Angels need to purify themselves when making love and both the Angel and partner must undergo a lengthy purification ritual (it takes several hours). They must also need to do it inside a specially crafted barrier and they both must not harbor any kind of possessive feelings while doing it, rather it must be done out of pure love. There were also traitors in the Heavens who were giving out information to the Khaos Brigade. Ironically, these top-class Angels were able to do so without falling due to a loophole in Heaven's system. These Angels, however, became Fallen Angels after leaving Heaven and escaping to the Khaos Brigade. Angels have jobs within the Church. These include "Angel Counselling" where they hear the confessions of people who have sinned and forgive them for their sins, naming children at the request of their parents, and regular work from file management to cooking classes and reception. All Angels can utilize Light Power that can cause severe damage to Devils and Fallen Angels, which can produce numerous light-based weapons such as spears, arrows, swords, a whip of light, balls of light and light rings, that can be used to grab hold of or restrain a foe with the size/power of a Fenrir pup. Spears appear to be the most commonly used weapons for Angels. Their light-based powers can also be used in different ways, but it is dependent on the individual angels, such as a light barrier or use light to enhanced physical attacks such as punches and kicks. A certain number of powerful high ranking Angels also has special holy abilities unique to themselves, like Uriel's ability to control Holy Fire and Baraqiel's power of Holy Lightning. Angels also have the ability of flight through their feathered wings. Like Devils and Fallen Angels, their wings are capable of retracting into their backs as if they've disappeared completely.

Nekomata are a species of cat Youkai that specialize in using ki. Most reside within the East Youkai Faction, who are under the rule of Magari, the leader of the Nekomata. The Nekomata mainly consist of females, with male Nekomata being rare among their species.[1] Female Nekomata generally mate with the males of different races, mainly with Human males, due to the traditional teachings.[1] Female Nekomata have a "mating season" where they go into heat, as seen by Koneko Toujou, who went into heat and attempted to seduce Issei Hyoudou in order to have his baby. The childbearing age range appears to differ compared to Human women as seen with Koneko, when Kuroka stopped her from mating with Issei, explaining she was still too small to give birth to a child despite being 16. Nekomata bear a striking physical resemblance to Humans, albeit possessing a set of cat ears and most commonly two tails. They also have eyes with slitted pupils. Certain Nekomatas such as Magari, has appearance which is completely that of a cat, albeit with multiple tails. Abilities Being a cat Youkai species, Nekomata naturally have great speed, reflexes and heightened senses. Nekomata are capable of a transformation to appear more human, however, this supposedly limits their natural capabilities to a certain degree until they regrow their ears and tails, it's not specified if they can fully transform into cats. Nekomata are also capable of performing Senjutsu and Youjutsu techniques. A Nekomata's power level seems to be determined by the number of tails they have, as exemplified by when Koneko grew a third tail and surpassed her sister in terms of strength, this also would explain how Magari has seven tails. Matured Nekomata have control over their mating season, as was shown by Kuroka, who didn't let her desire for mating cloud her mind, but young Nekomata like Koneko do not. A experienced Nekomata can also control the mating season of other Nekomata, since Kuroka was able to "switch off" her sister's heat, while Magari was able to force Koneko and Kuroka to enter their mating seasons from a short distance.

The Nekoshou (猫魈, Nekoshō) is a special variant of Nekomata and are the strongest among their kind. Nekoshou are a high-level Youkai species that are capable of mastering both Youjutsu and Senjutsu. The only known Nekoshou are Kuroka and Koneko Toujou, as the Nekoshou are stated to be extremely rare and on the brink of extinction.

It formerly served as the main base for Rias Gremory and her peerage prior to Rias' graduation from high school The Occult Research Club of Kuoh Academy was originally abolished due to a lack of members. Upon their entry into high school, Rias and Akeno revived the club as the president and vice-president, eventually changing it into the home base for Rias and her servants. The club itself serves as a front for Rias' servants, and other supernatural individuals who appear later in the series, in order to get out of school activities or lessons in case of an emergency, such as having to hunt down a Stray Devil or to destroy a Fallen Angel. The abandoned dormitory was secured through the school's resources and is used as a base that prevents scrutiny from other students. In Volume 8, it is shown that there is some truth to the name, as in order to remain in a human school, Rias must still fulfill her Devil school requirements, which includes the study and research of Youkai and other supernatural creatures in the area. Following Rias and Akeno's graduation, Asia and Yuuto are chosen as the next Club President and Vice President while newer members like Le Fay and Bennia join in as first year students Exterior The club house is a three story building, with the third story serving as a clock-tower. It has been painted white with a black roof with vines creeping up to the second story. Interior The club room interior is a wood-paneled room with Victorian-style couches and chairs along the walls. One side is set up to be able to be used as a bath, and a large Gremory Family magic circle is also there to allow teleportation to and from clients.

Not much is known about Kuoh Academy, other than the fact that it was originally an all-girls private school. At some point before the start of the series (when the old school building was still in use) Kuoh Academy changed into a co-ed school and the new school building was constructed, although there are still more girls than boys studying at the school. The Kuoh Academy has several divisions such as the primary division, high school division and college division. The high school division of Kuoh Academy has multiple annual events such as the Ball Tournament, Sports Day, School Trip for second year students and School Festival. Kuoh Academy boys' uniforms consists of a black blazer with white accents over a white, long-sleeved, button-down shirt with vertical linings, a black ribbon on the collar, matching black pants, and brown dress shoes. Kuoh Academy girls' uniform consists of a white long-sleeved, button-down shirt with vertical linings, a black ribbon on the collar, a black shoulder cape and matching button-down corset, and a magenta skirt with a white underskirt beneath it. Both of the uniforms' dress shirts also have short-sleeved versions for spring and summer; for the boys, without the blazer, while the girls, without the shoulder cape. For gym, the uniforms consist of a white short-sleeved t-shirt with navy blue accents with the Kuoh Academy emblem embroidered on the front, left side, navy blue bloomers (for girls) or shorts (for boys), and navy blue and white sneakers. For colder climates, the girls wear a pink and white tracksuit with black accents, while the boys wear a grey tracksuit with identical features.The Student Council is the Academy's student body where its members attempt to keep order within the school grounds. It was used as the main base of Sona Sitri's peerage during her tenure as Student Council president. It is currently led by Xenovia Quarta and Genshirou Saji. Tennis Club A sports club of the school, previously led by Kiyome Abe. During which she taught the monsters who serve her to play tennis. Girls' Kendo Club A sports club shown in the anime.

Fallen Angels are Angels that have fallen from the grace of God, due to having "impure thoughts" that divert them from the teachings of the God in the Bible. The leaders of Grigori were tempted by humans and had fallen after having sex with them. Despite being cast out of Heaven, Fallen Angels and their subordinates have been known to occupy churches and use them as bases. However, they go out of their way to destroy all of the religious icons in these churches in the process out of spite for their former leader. Currently, the Fallen Angels have the smallest population among the Three Factions. Fallen Angels have an appearance similar to their Angel counterparts with their wings; however, their wings are colored black as opposed to the Angels' white wings. Also, because they have been cast out of Heaven by God, they also lack the halos above their heads. They are also often seen wearing dark-colored clothes, mainly pertaining to the colors black and violet. Like their Angel counterparts, the power of a Fallen Angel also contribute to how many wings they have. For example, Azazel, the former leader of the Fallen Angels, has six pairs of wings (twelve altogether) which justify his power. This extends to half-Fallen Angels as Akeno gained more fallen angel wings as her power increased. The blackness of the wings of each Fallen Angel is also different. Azazel, for example, has jet-black wings with feathers that have the color of everlasting darkness. Female Fallen Angels possess seductive bodies in order to seduce men. This trait carries over to half-Fallen Angels, with Akeno's body considered particularly seductive. Although they have been cast out from Heaven, Fallen Angels retain the ability to use Holy Power and create Light Weapons. This type of weaponry is extremely harmful and poisonous to Devils, as it is shown many times when Issei is wounded by Dohnaseek and Raynare. Fallen Angels have the ability of flight via their feathered wings, their wings have also been shown to retract into their backs as if they've completely disappeared. The Fallen Angels can use the feathers of their wings as projectiles to pierce their opponents, with the feathers being as hard as steel and are also capable of using their wings for both offense and defense.

The original God of the Bible created the Sacred Gears as part of his system to enact miracles on Earth. Yuuto Kiba has stated that certain individuals with Sacred Gears have grown to become very powerful and influential, and that a large number of the people who've had their names etched into history, were most likely Sacred Gear possessors. Sacred Gears varies from the common Twice Critical to the rare Sacred Gear Twilight Healing, with the only exception being the Longinus, which are all unique in their own way. There can be more than one Sacred Gear of the same type such as Blade Blacksmith. If a Sacred Gear is removed from the owner, they would die. Humans or Human hybrids are the only species able to be born with Sacred Gears; however, they still maintain them upon their reincarnation into Devils and Angels. The Fallen Angels from Grigori devised a ritual able to extract a Sacred Gear from the original owner and use it for themselves, this results in the death of the original owner. It is possible for a person to own more than one Sacred Gear at the same time. However, this almost always happens because the individual comes to a second or even more Sacred Gear through irregular circumstances than through birth. As an example: Yuuto Kiba obtained his second Sacred Gear, Blade Blacksmith, from the Holy Element he received from Valper Galilei. Inside the Holy Element, was the soul of one of his former comrades who originally owned this Sacred Gear, allowing him to pass it on to Yuuto. Another case is Mitsuya Kanzaki, who isn't the original owner of Telos Karma nor Innovate Clear, but instead uses a special terminal to wield them. As there have not been any individuals in the series who have been born with multiple Sacred Gears, it may even be possible that people are always born with a single Sacred Gear.

Holy Element, also known as Holy Factor, is the factor which grants anyone the ability to wield the Holy Swords. The Holy Element displayed has a bizarre diamond shape to it and has a dark shade of blue and indigo on its outside. The inside is a distorted color when it contains the holy properties of a person which can be either pink, purple, yellow, or green. Summary The Holy Element is the factor that enables Humans to wield Holy Swords, although only those with the proper "numerical value." Valper Galilei discovered this during the Holy Sword Project, and then removed, gathered and crystallized the holy properties of countless Human victims in order to create artificial Holy swordsmen who were capable of wielding even the strongest Holy Swords in existence like Excalibur.

Magic is a power seemingly generated from other forms of energies, and is a power that even Humans can control. There exist multiple types of Magic, such as Norse Magic, Fairy Magic, and various different types of Magic with different equations, including the Magic that Gods & their respective pantheons use. It is said that the majority of Magic used by ordinary Human Magicians are those created by the great Magician Merlin Ambrosius, which involved reading the flow, and was born by researching the Demonic Power of Devil's. Abilities All kinds of Magic are used in for many purposes such as offense, Defense, supporting, Healing, as well as other, more practical or mundane purposes.

Ascalon is a Holy Sword previously wielded by Saint George, the Dragon-killing Saint. Unlike the other Holy Swords, Ascalon specializes in killing Dragons and is named the Dragon Slayer The known Excaliburs are Excalibur Destruction, Excalibur Mimic, Excalibur Rapidly, Excalibur Nightmare, Excalibur Transparency, Excalibur Blessing, and Excalibur Ruler. The Excalibur Swords were fused into the Durandal and later split from it and merged into the True Excalibur. Durandal is a Holy Sword that was previously wielded by the Paladin of the Holy Roman Emperor Charlemagne: Roland. Roland had used the sword to fight an army of 100,000 men. It is a Holy Sword that is said to be on par with the original Excalibur. Holy Swords are known to be one of the creations of Gods, but there are those who reached the domain of God who created some of the most renown Holy Swords through using Magic and Alchemy, which resulted in the creation of "true" Holy Swords wielded by legendary heroes such as the original King Arthur wielding Caliburn and the True Excalibur, and Roland with Durandal. There are also Holy Swords in factions such as Japan, but these are commonly referred to as Holy Spirit Swords, like the Totsuka no Tsurugi and Ame no Murakumo no Tsurugi. In the current era, there are modern recreations of Holy Swords by the Church's Alchemists such as replicas of Excalibur and Durandal, though these are greatly inferior in terms of overall power. By Volume 23, more powerful recreations of legendary Holy Swords are created due to the Church's Alchemists using technique of the Three Factions, including Fallen Angels and Devils, such as Durandal II which power rivalled the original Durandal. For one to be capable of wielding a Holy Sword, they must possess a high amount of Holy Element in their bodies. However, natural Holy Sword wielders only appear once in a decade. There are methods to create artificial Holy Sword wielders, such as through a special blessing ceremony to place the Holy Element into them,and to transfer the Holy Element from one person to another. However, the process is not always successful, as some people are incapable of adapting to the Holy Swords. In extreme situations, those who are unable to adapt to the Holy Element can suffer death. In addition to their Holy Powers, which is extremely lethal against Devils and creatures of darkness, as well as Fallen Angels, all Holy Swords, especially the strongest ones such as Caliburn and Durandal holds immense offensive power. Almost all Holy Swords, especially those created by the Biblical God, grants their wielder unique mystical abilities similar to Sacred Gears, such as the Strongest Holy Sword Caliburn granting its wielder the power to manipulate space and the True Excalibur providing their wielder seven different abilities (shapeshifting, invisibility, subjugation, illusions, enhanced speed, and massive destructive force). As shown by Yuuto Kiba's usage of Durandal, certain Holy Swords can also change depending on the wielder

Pure-Blooded Devils (純血悪魔, Junketsu Akuma) are pure Devils such as the original Four Great Satans and the original Devils created by the Mother of all Devils; Lilith, including the first generation aristocrat Devils of the 72 Pillars and Extra Demons, each who ruled their own domain in the Underworld along with their Pure-Blooded descendants. Each clan of 72 Pillars has a unique ability that is specific to their clan which originated from their progenitor, such as the Bael's Power of Destruction or Phenex's Immortality, as the descendants of the clans are born with such unique abilities which occasionally get passed to other clans as Pure-Blooded High Class Devils interbreed with each other. Issei promoting to Queen Issei Hyoudou, a Reincarnated Devil. Reincarnated Devils (転生悪魔, Tensei Akuma) are created by High-class Devils using Evil Pieces to reincarnate other species into Devils; who serve the High-class Devil who is their King. Reincarnated Devils also appear to have much higher fertility than Pure-Blooded Devils, as in the special novel High School DxD EX that takes place 30 years in the future, Issei's future children were born in a short amount of time, with Koneko and Kuroka's children being born on the same day. Stray Devils (はぐれ悪魔, Hagure Akuma) are Reincarnated Devils who have diverted away from their masters for their own selfish desires. Without their masters to keep their powers in check, they become a great threat if their powers go beyond their control. The Devils take this case very seriously, and any Devil who becomes a Stray will usually be killed on the spot. Mixed Heritage Devils (混合遺産悪魔, Kongō Isan Akuma) are Devils either born between a Pure-Blooded Devil and a Reincarnated Devil, or between two Reincarnated Devils. They could not be considered as Half Devils due to both their parents being Devils, and are not considered Pure-Blooded Devils due to their diluted blood as High-Class Devils look down on Reincarnated Devils. Possible famous Mixed Heritage Devil would be Coriana Andrealphus, which could explain why the Andrealphus is stated to be extinct in the Light Novel Volume 8, but considered active in the first lore. Vali appears before Issei and Koneko Vali Lucifer, a Half Devil. Half Devils (半悪魔, Han Akuma) are Devils of mixed heritage created by the interbreeding of Devils and other species, most notably Humans. Due to the Pure-Blooded Devils pride and their obsession with pureblood purity, the Half Devil descendants of the Pure-Blooded Devil clans are often scorned and looked down upon. However, due to their mixed blood they gain the abilities of both species, as Half Devils with Human heritage can manifest Sacred Gears. Two famous Half Devils are Vali Lucifer and Ingvild Leviathan, who are the half-Human/half Devil descendants of the original Satan clans, in addition to being the possessors of the Longinus Sacred Gears. Super Devils (超ちょう越えつ者しゃ, Chōetsusha{{{2}}}), also known as Transcendental Beings are Devils considered irregular beings due to possessing abilities surpassing realm of Devils, making others wonder whether or not they can be considered devils. At first, three people were considered Super Devils: Sirzechs Lucifer, Ajuka Beelzebub and Rizevim Livan Lucifer who have power exceeding Satan-Class Devils; Sirzechs and Ajuka, in particular, has enough power to be considered among the "Top 10 Strongest Beings" using their full power. In fact, their coup d'etat against the Old Satan government succeeded partly due to Sirzechs and Ajuka's support. After the Evil Dragon War, due to their continuous and abnormal growth, the current Heavenly Dragons: Issei and Vali were nominated as Super Devil candidates. After the Hell Disaster, they were both officially certified as Super Devils after being approved by Zekram Bael. Furthermore, Hades' research created two Super Devils named Balberith and Verrine, but they haven't been certified by the underworld government.

The Sitri Clan is one of the remaining 32 Devil clans of the 72 Pillars and one of the highest-ranking (ranking at Prince), and famous, Devil families. While not much is known about the incumbent head of the house, it has been revealed that the next head is Sona Sitri. After her father started to show symptoms of the Sleep Disease, he was forced to step down, making Sona the new Head of the clan. Being the house that produced the current "Leviathan", members of the Sitri Clan have strong affinity for water-based magic, with the only known exception being Serafall Leviathan who excels in ice-based magic. The Sitri territory is known for its richness in nature, and is said to boast the most of the natural reserves present amongst the few territories belonging to High-Class Devils. The Sitri Clan are also known to be one of the few territories which have advanced medical facilities as well, having one of the most famous hospitals in the Underworld. Powers Members of the Sitri Clan have great mastery over Water manipulation. Serafall is noted to have the ability of Ice manipulation.

The Longinus (神滅具ロンギヌス, Ronginusu), also known as Tools that Destroy God (神滅具, Kamimetsugu), are the thirteen original top-tier Sacred Gears with enough power to kill Gods, as well as five additional Sacred Gears that evolved to the same level. Longinus are also known as the Embodiments of God’s Destruction, the Divine Destruction Tools and the Supreme Sacred Gears. This class of Sacred Gears is specifically named after the True Longinus, the first and most powerful. Unlike others Sacred Gears, that has more than one of the same type, the Longinus are utterly and completely unique, and only one of each may exist at a time. Azazel has stated that all Longinus is just a combination of one ability with another. Essentially, they combine powerful abilities that aren’t supposed to be combined. All of the Longinus are considered the strongest Sacred Gears in their respective categories such as Dimension Lost being considered the ultimate barrier-type Sacred Gear or Annihilation Maker being considered the ultimate creation-type Sacred Gear

The Old Satan Faction (旧魔王派 KyūmaŌ-ha) was a group comprised of pure-blooded Devils that fanatically supported the world domination ideals of the original Satans, Beelzebub, Lucifer, Asmodeus, and Leviathan, had allied themselves with their descendants. After the organization's dissolution after the Devil Civil War, the remnants of the Old Satan Faction were scattered through out the Underworld. Several hundred years later, the organization was reformed as a wing of the Khaos Brigade, becoming its largest faction. The Old Satan Faction was formed during the Devil Civil War, when a group of Devils decided to continue the Great War in order to fulfill the Original Satans' ambition of world domination, while another group of Devils was against it, resulting in a Civil War among Devils, with the victor being the new Government of the Devil side of the Underworld, while the losers were forced to go into hiding and the original Four Great Satans became known as the Old Satans.

The Rating Game was created after the introduction of the Evil Pieces by Ajuka Beelzebub. The Rating Game is used to measure a Devil's strength which will reflect their social standing in the Underworld. In fact, the Rating Game is so famous that the Top 10 ranked are considered as heroes to the Devils. In Volume 10, Yuuto mentioned that the Top 5 ranked are said to be unmovable, with all 5 having held their position for a long time, especially the 3rd ranked Bedeze Abaddon, the 2nd ranked Roygun Belphegor, and the 1st ranked Diehauser Belial. All three of them are said to be Ultimate-Class Devils among Ultimate-Class Devils and have power equal to the current Satans until it was revealed that Roygun and Bedeze had used the King Piece to strengthen their power, which leaves only Diehauser. Game Field The Game Field is where all Rating Game matches take place and is located inside a section of the Dimensional Gap, protected by a barrier. This field was created by Ajuka and the technicians who work under him. The field itself provides a simulation of any environment or scenery for a game to take place in. Rules The game takes the form of a strategic battle between the King and his/her pieces. It is fought on a map of their choosing, and can be created to be a perfect replica of any location they desire. Only matured Devils are allowed to participate in official Rating Games. The servants of the Devils are named after the pieces of chess: Rook, Knight, Queen, Bishop, and Pawn. The maximum number of players in a Rating Game is 16 and like the game of chess, the players lose when their King loses. The Rating Game (レーティングゲーム Rētingu Gēmu) is a competition between two Devils with a peerage. The Rating Game shares many similarities with the board game; Chess. As of Volume 22, there is now an Rating Game World Tournament called the "Azazel Cup"; named after Azazel where all mythologies can participate.

The Evil Pieces, also known as the Devil's Pieces (悪魔の駒, Akuma no Koma), are a set of 15 chess pieces given to High-class Devils to increase their ranks by reincarnating other beings into Devils The Evil Pieces were created by Ajuka Beelzebub sometime during the 16th century using the crystals available in the Agreas Island to help replenish the number of Devils after the Great War which had caused the death of countless Devils. While many Devils were able to adapt to the Evil Pieces, the Old Satan Faction rejected the usage of the Evil Pieces, believing them to be a disgrace to Devils for reincarnating Humans and other races into Devils. The creation of the Evil Pieces eventually lead to the creation of the Rating Game.[1] Evil Pieces are commonly given to Pure-blooded High-class Devils, so that they can gather servants of their own. Reincarnated Devils are also given the chance to receive Evil Pieces should they rise in rank and become a High-class or Ultimate-class Devil like Tannin and Rudiger Rosenkreutz. When a Devil receives the right to obtain the Evil Pieces they are required to go to the Satan's territory and touch a monument which functions as a replacement King Piece to register themselves as King.[2] A Devil who declines Evil Pieces can apply for them later. Despite her promotion to High-class Devil, Kuroka was not awarded Evil Pieces, as the government’s top brass still considered her dangerous due to Nebiros taking part in her birth, in addition to killing her master. If a King wishes to trade a Piece with another King, a ritual must be performed. A trading-purpose magic circle must be drawn. The Kings stand at the side of the magic circle while their pieces stand in the centre of it. The Kings increase their auras while putting their hands forward and activate the written Devil symbols to circulate. The auras of everyone around them begin to glow and synchronize, bypassing the magic circle. With that, the ritual will end and the trade is completed in a simple manner. A trade can still occur even if one of the pieces of the other party has not been used. It is also possible to trade multiple pieces simultaneously, even if they come from different peerages. Based on the game of chess, there are a total of 15 pieces (1 Queen ♛, 2 Rooks ♜, 2 Bishops ♝, 2 Knights ♞, and 8 Pawns ♟) that are given to High-class Devils (King ♚) with a peerage.[4] These pieces are used to reincarnate other beings into Devils and become servants of the High-class Devil.

Queens (女王クイーン, Kuīn) are worth 9 Pawns.[8] Queens possess all the characteristics of Rooks, Knights, and Bishops, making them the most balanced piece as well as the most powerful.[1] Within individual peerages, Queens typically act as their master's second-in-command, overseeing the rest of the peerage.

Rooks (戦車ルーク, Rūku) are worth 5 Pawns.[8] Rooks gain superhuman strength, leading to high offense and defense.[1] However, they are not very quick, and can get beaten easily by a high-speed opponent. It was mentioned in Volume 2 and shown by Rias in Volume 4 that the King can perform Castling with a Rook piece.[9] In later Rating Games, it is demonstrated that Castling can be performed with people who hold Rook pieces.

Bishops (僧侶ビショップ, Bishoppu) are worth 3 Pawns.[8] Bishops gain enhanced demonic power and magical abilities which they can use to conjure up a multitude of spells (offensive, healing, etc.). However, more powerful spells consume most of their demonic and magical powers, which takes a long time to regain, forcing them to use their power carefully or risk becoming vulnerable to physical attacks.

Knights (騎士ナイト, Naito) are worth 3 Pawns.[8] Knights gain increased speed and mobility, enabling them to perform high-speed attacks and maneuvers.[1] However, their main weakness is their low defense, making them vulnerable to powerful attacks if they are not careful. Another weakness among knights are their legs; if their legs are injured, their mobility is greatly reduced.

Pawns (兵士ポーン, Pōn) are worth 1 Pawn each.[8] The traits of Pawns is the ability to promote into a Queen, Rook, Knight, or Bishop in enemy territory (as seen in the anime when Issei enters the church to save Asia) or with the permission of their King (as seen when Issei asked Rias for permission to promote before fighting Riser to break off the engagement).

King (王キング, Kingu) pieces are rare pieces created in the early days of the Rating Games. Unlike the other pieces which grant special abilities, the King Piece simply boosts a person's power. However, the King piece's strengthening is anywhere from 10 to 100 times and more. There are restrictions to its use. One, the user cannot already have an Evil Piece(s) because the King piece would overlap with their current piece(s) and expose them to dangers. Two, the user can potentially die if they are too strong. There are only nine unused King Pieces in existence, but they were banned by the current government from use for fear that Devils would use it to pursue evil desires. After Volume 21, the King Pieces have been confiscated.

The reason for the potential of Balance Breaker's in Sacred Gears is unconfirmed. Azazel claims that Balance Breaker is a "bug" in the system created by the God of the Bible, while others such as Loki believe it to be an intentional feature. The Balance Breaker is initially considered a forbidden power by the Three Factions. It is known as the ultimate state of activation for a Sacred Gear. Balance Breaker is often triggered by high emotions combined with a change in the heart or spirit of the wielder. There is an incomplete state for Balance Breaker which is called Over Booster (オーバー・ブースター, Ōbā Būsutā). There are cases where a Sacred Gear user was born with the ability to use Balance Breaker, such as Tobio Ikuse. This is a rare occurrence among any type of Sacred Gear wielder, as most Sacred Gear wielders who were born with the ability to use Balance Breaker without needing to attain it died of or became unstable with their power. The Balance Breaker is the most powerful manifestation of all Sacred Gears in which the possessor's feelings trigger this evolution. Once reached, the Balance Breaker can be entered again far more easily than the first time. With proper training, it can be maintained for longer periods of time, as with the case of Vali Lucifer. While initially both Yuuto Kiba and Issei Hyoudou could only maintain it for short periods of time, undergoing intense training helped them improve this time. When first introduced, Vali could maintain his Balance Breaker for a month

Age 38 Gorou Hyoudou (兵藤 五郎ひょうどう ごろう, Hyoudou Gorou) is an ordinary office worker. Gorou has the appearance of a middle-aged man with brown hair and brown eyes which his son inherited, as Issei is noted to resemble him. He is shown to wear glasses. He is shown to be exasperated with his son's lewd behavior as he worried that he wouldn't be able to become a grandfather due to Issei not finding a bride. Nevertheless, Gorou is shown to love his son very dearly, due to having to deal with the loss of his two previous unborn children with Miki to miscarriages, he did everything he could to ensure Issei was born safely when Miki was pregnant the third time and hopes he lives an honest life. He became happy with Issei's increasing popularity among girls and hopes to become a grandfather soon, as he has accepted the various girls that love Issei as his daughters-in-law. Like his son, Gorou is shown to be brave as he stood in front of Issei to protect him from Rizevim Lucifer when Issei was unsure if his parents loved him and when Gorou stood to protect Kunou, Ophis and Lilith from Thanatos' Grim Reapers. Mitsuya Kanzaki considers him a good father. Similar to Issei, Gorou had unbreakable determination as in the past while praying for Issei's safe birth, Gorou painstakingly prayed non-stop in a Shinto shrine during winter, while doing Hyakudomairi barefoot in the snow disregarding the cold. Despite criticizing Issei for his lewd behavior, it is revealed that Gorou is lewd himself, as he too dreamed of having a harem like Issei when he was younger and is proud of his son for being able to achieve that dream. He is also shown to have nosebleeds when he sees the girls doing lewd things for Issei, as he encourages Issei to make the girls his wives.

Miki Hyoudou (兵藤 三希ひょうどう みき, Hyoudou Miki) is Issei's mother and a full-time housewife. She has the appearance of a middle-aged woman with dark brown hair that is tied into a ponytail and hazel eyes. Miki is shown to be exasperated with her son's lewd behavior as she worried that she wouldn't be able to become a grandmother due to Issei not finding a bride. Despite this, she is shown to dearly love her son and watches him carefully as she is able to tell what he is thinking and feeling. She became happy with Issei's increasing popularity among girls and hopes to become a grandmother soon, as she is shown to be excited when she caught Issei and Asia in the bath together or when Issei started calling Rias by her name. It is revealed that the reason Miki Hyoudou held such great love for her son was that in the past she had already been pregnant twice before giving birth to Issei, her first pregnancy was ten years before Issei was born and her second pregnancy occurred two years after her first pregnancy. Due to having a constitution that makes it difficult to conceive and bear children, her first and second pregnancies ended in miscarriages, it was around eight years after her second miscarriage that she became pregnant for the third time, successfully giving birth to Issei after painstaking efforts by both Miki and Gorou to ensure they would succeed in having a child. She is shown to be protective of her family Despite criticizing Issei for his lewd behavior, it is revealed that Miki is lewd herself as she was stated to have worn a naked apron when she was younger for her husband and is shown to be comfortable with Issei and Asia having sex in the kitchen, even commenting that she would have loved to watch. She is an excellent cook and sometimes goes out to a part-time job.

The Hyoudou Residence is the home of Issei Hyoudou and his parents. It would later become a base of operations for the allied factions in Volume 5, following the appearance of the Khaos Brigade. After its renovation, it also became the home for almost all the current and former female members of the Occult Research Club, the female members of the Vali Team: Kuroka and Le Fay Pendragon, the Princess of the Kyoto Youkai: Kunou, the envoy of the Camilla faction: Elmenhilde Karnstein, the angel Lint Sellzen and the Dragon God: Ophis, and her spawn: Lilith. The Hyoudou Residence was originally a normal two-story terrace house with a light blue exterior, a balcony on the second floor, and a brown roof. It would later be renovated by the Gremory Clan in Volume 5 of the light novels into a large, six-story house with three large basements. First Floor: Includes the living room and kitchen. Second Floor: Includes Issei's room, Asia's room, Rias' room, Issei's parents' room, and a bathroom. First Floor: Includes guest rooms, the living room, kitchen, a bathroom, and Japanese-styled rooms (washitsu).[11] Second Floor: Includes Issei's, Rias', and Asia's rooms, with Issei's room being in the middle. It has two interconnecting doors on each side: one connecting to Rias' room and one connecting to Asia's room.[11] Third Floor: Includes Issei's parents' room, a study, and a storeroom.[11] Fourth Floor: Includes Akeno's, Xenovia's, and Koneko's rooms.[11] Fifth Floor: Not much is known about the fifth floor as of yet, probably includes Irina's, Rossweisse's and Ravel's rooms. Sixth Floor: Originally an empty floor, the top floor was converted into a meeting room for the Three Factions (also known as the VIP Room). Rooftop: The rooftop is a communal garden decorated with flower plots and there is a small vegetable farm planted. There is also a table and chairs to drink tea at. The rooftop is also home to Ophis' shrine which is located at the corner of the rooftop, which she can use for sunbathing.[12] First Basement Floor: Includes a movie theater, training rooms, changing rooms, and a large indoor bath which has a refrigerator filled with three different flavors of milk (fruit milk, regular milk, and coffee milk). A hidden room on this floor also becomes Kuroka's and Le Fay's room. The second hidden room also contains an assortment of baths of various sizes, but are noticeably larger than the first and are decorated gorgeously with ornate patterns, tropical plants, Dragon statues pouring water into the bath, and the Gremory's symbol. Second Basement Floor: Includes a heated indoor swimming pool. Third Basement Floor: A mostly vacant floor that is generally used for storage. It also includes a library. All floors in the renovated house are accessible via an elevator. There appear to be hidden rooms in the residence due to the designer of the house having a fondness for hidden rooms. Two of such are located in a corner that leads to a dead end on the first basement floor and at the corner of the bath. The other hidden rooms have yet to be discovered.

Usually Beings who can use magic preform a summoning do so by simply casting a magic circle for their summoning to appear.

(Volume 1, Life.1) - Her hair also has loose bangs covering her forehead and side bangs framing her face. (Volume 1, Life.1) - Rias' height is 172 cm. (5 feet 8 inches), making her one of the tallest female characters of the series.

(Volume 1, Life.1) - Rias also tends to wear seductive lingerie and thongs, especially when she has a desire to sleep with Issei. (Mentioned/Implied early, e.g., Volume 1, Life.6) - On some rare occasions, Rias wears glasses when she's deep in thought, as she feels they make her mind work better despite having perfect eyesight. (Occasional detail, mentioned later volumes/side stories) Annotated Rias Gremory Biography: Personality: - As a Devil from the House of Gremory, Rias is very kind and compassionate, especially to her servants and people close to her. (Volume 1, Life.1 onwards) - She gets angry and violent whenever people insult her or her peerage, showing a fiery side to her. (Seen clearly Volume 2, Life.4 & New Life; Volume 1, Life.4 & New Life) - This also plays into the fact that she dislikes cruelty towards people, as shown with her disgust over Marius Tepes, who abused his own sister for his own benefit (Volume 24, Life.-1), and how she killed the Fallen Angels, such as Mittelt, Dohnaseek, Kalawarna, and Raynare for their cruel treatment of Issei. (Volume 1, New Life) - Rias also holds great sympathy towards Sairaorg and his mother Misla Bael for how badly they were treated by the Bael clan. (Shown Volume 5, Life.5; Volume 10, Life.4) - Rias is proud of her family's name, but she does not like being seen as Rias of the Gremory Family. (Stated Volume 2, Life.2) - The reason for her living in the human world (as revealed in Volume 2 of the novels) is because there, everyone sees her as Rias, not as a Devil or as the Crimson-Haired Ruin Princess. (Revealed Volume 2, Life.2) - Due to this and the fact that the only men who showed interest in her were interested in her due to being the Heiress of the House of Gremory, Rias soured on the idea of finding a lover, until meeting and falling in love with Issei. (Context Volume 2, Life.2; Develops Volumes 1-2; Solidified post-Volume 2, New Life) - She thinks of Issei as a special person (Volume 1 onwards) and always gets jealous when girls are around him, becoming a totally different person when she sees him and other girls together, or when it comes to training. (Jealousy apparent early, e.g., Volume 1, Life.3/4; Volume 3, Life.2; Recurring early volumes) - Despite her mature stature like a woman, Rias tends to act her true age and becomes frustrated whenever girls flirt with Issei. (Contrast shown Volume 3, Life.4; Recurring trait) - While Rias is usually calm and mature in most situations, she loses her mature aura and presence when she sees any girl (especially Akeno) flirting with or seducing Issei. (Frequent occurrence, prominent Volume 3 & Volume 4) - She enjoys teasing Issei and Asia (Volume 3 onwards), but at the same time makes it clear (to Asia or any girl) that Issei is hers, and she does not want to share him at all. (Possessiveness shown Volume 3, Life.4; Recurring early volumes) - The Gremory Family and their servants are beings with extraordinary affection among the Devils, and Rias is no exception. (General series theme) - She has no problem with showing Issei her breasts or sleeping naked with him (which she always does according to her and claims she can't sleep without being nude or without Issei). (Sleeping naked mentioned Volume 1, Life.6; Comfort shown multiple times, e.g., Volume 2, Life.1) - Despite being seductive like Akeno, both of the girls are still innocent to love, as both of them become their age whenever around Issei or on a date with him. (Evident Volume 3, Life.4; Volume 5, Life.4) - After becoming Issei's girlfriend (End of Volume 10), Rias begins to show more confidence in her relationship with Issei and is no longer jealous or angry when Issei is with other girls like she previously was, even accepting Issei's dream of having a harem and letting the girls have dates with him. (Acceptance solidifies Volume 11 onwards, e.g., Volume 12, Volume 17) - However, Rias still shows some signs of jealousy such as when Issei doesn't spend enough time with her, but she still believes in him and loves him. (Lingers post-Volume 10, e.g., Volume 17) - Due to being Issei's official girlfriend and later fiancée, the other girls acknowledge her as the "Legal Wife" as she manages the other women who are in love with Issei. (Status solidifies post-Volume 10/11) - According to Ravel, the burden of Rias as the "Legal Wife" is greater than the burden of Issei as she has to manage the girls' maidenly feelings towards Issei and balance out Issei's feelings towards each of his lovers/brides. (Ravel's observation Volume 22, Life.3) - Like Akeno, Rias shows a sign of dependence toward Issei (possibly lesser than the former) as Rias will lose her will to fight and lead for some time if Issei is severely injured or she believes that he is dead. (Shown Volume 11, Life.4/New Life; Volume 2, New Life) - She developed an instinct when Issei is with an unknown woman or other girls tried to seduce him before her she immediately rush to him quickly. (Recurring gag/trait, later volumes, e.g., Volume 17, Shin High School DxD Volume 1) - Rias holds her older brother, Sirzechs, in high regard (despite her older brother's antics of being a siscon) because she deeply cares for him. (Consistent throughout, e.g., Volume 12) - When Rias was a child, she was entirely dependent on him and held him in admiration, while also feeling inferior to him at the same time. (Alluded to, context Volume 2, Life.2) - Rias loves participating in Rating Games, as she dreams of becoming the Rating Game champion by defeating the current Rating Game champion; Diehauser Belial, with the help of her peerage. (Consistent passion; Goal mentioned ~Volume 10, Life.1) - While Rias is a powerful devil in her own right, being much stronger than average High-class Devils and according to Azazel, being able to become a Ultimate-class Devil just on the virtue on her talent alone (Azazel's comment Volume 4, Life.4), Rias suffers a bit of an inferiority complex when she compares herself to her fellow Rookies Four colleagues, as she feels inferior to Sona as a strategist (~Mentioned Volume 5, Life.3) and that she is far weaker in power than Sairaorg. (Evident Volume 10, Life.4) - However, according to Riser and Azazel, Rias has a talent for finding and recruiting talented individuals for her peerage, inspiring great loyalty and growing stronger with them as seen in her meeting with Issei. (Riser Volume 2; Azazel ~Volume 5, Life.5 / Volume 10, Life.1) - During the Azazel Cup, she was highly evaluated as a scout as she managed to recruit Crom Cruach (Volume 24, Life.1) and Vasco Strada (Shin High School DxD Volume 1, Life.1), along with two Longinus possessors (Issei Volume 1; Gasper Volume 4), being praised by the professional critics. (Commentary during Shin High School DxD Volumes 1-4) - She is noted to be a skilled negotiator, as she was able to convince Rossweisse to join her peerage by offering her better working conditions and a better salary compared to her previous job in Valhalla (Volume 7, New Life), and while during the Azazel Cup, she was able to convince Vasco Strada to join her team after he declined all prior invitations to participate in the Cup by appealing to his warrior swordsman spirit and offering to restore his youth without using a Devils ability, thus not violating his faith, with Strada praising her negotiating skill as a sweet Devil's whisper. (Shin High School DxD Volume 1, Life.1) - Rias is competitive and hates to lose, especially after losing her first Rating Game against Riser as she strives to always win, whether it is in sports or Rating Games. (Reaction Volume 2; General spirit e.g., Volume 14, Life.2) - Due to being spoiled by her father Zeoticus and her brother Sirzechs from an early age, she has a somewhat impatient and selfish personality. (Underlying trait, background from Volume 2) - Being a spendthrift, Rias enjoyed shopping as a hobby (e.g., Volume 13, Life.1) and because of her bad money spending habit, her mother Venelana and her sister-in-law Grayfia often scold her for her frivolous spending, as her mother reconsidered the amount of money she is allowed as allowance. (Mentioned Volume 13+ / DX Volumes) - Early in her childhood, she developed an instinctive fear and hatred of camels due to being hit by a camel after making fun of it, as the fear is great enough that the residents of the Gremory territory constantly keep camels away from her despite the Gremory's association with camels in the Ars Goetia. (Revealed Volume 8, Extra Life) - Due to being taught about Japan from Souji Okita (Mentioned Volume 13, Life.1), Rias is a complete Japanophile who is obsessed with Japan's culture and history, buying various Japanese souvenirs and being ecstatic while visiting Kyoto during her school field trip (Volume 13, Life.1 - Life.4), though she became pouty and stomped at the train station due to being unable to fully explore Kyoto (Volume 13, Life.4). - She also founded a Japanology club after graduating from high school. (Mentioned Shin High School DxD Volume 1, Short Story or similar) History: - Rias is the daughter and second child of the Gremory Family. She became the heir after her brother, Sirzechs, became the Satan Lucifer, losing his right as heir to the house. (Background established early, e.g., Volume 2, Life.2) - After being announced as the heiress of the Gremory Clan, Rias was eventually placed into engagement with Riser Phenex. (Central plot Volume 2) - When she was a child, she was attacked by a camel for making fun of it, which caused her to have a strong fear of camels ever since. Just seeing imagery of a camel is enough to trigger her fear, as shown when she gets frightened seeing her clan's mascot, which is a camel. (Revealed Volume 8, Extra Life) - Prior to the series, Rias has reincarnated Akeno Himejima, Koneko Toujou, Yuuto Kiba, and Gasper Vladi as members of her peerage. (Pre-series history revealed gradually) - Rias met Akeno, her Queen, first servant, and best friend, in Japan, saving Akeno from being killed by her fellow Himejima Clan members after Akeno accidentally entered Heinrich Cornelius Agrippa's territory. (Akeno's backstory Volume 4, Life.3) - She then met Koneko, her second servant, after her brother rescued Koneko from being executed, leaving Koneko under Rias' care. (Koneko's backstory Volume 5, Life.3) - She later reincarnated both Yuuto and Gasper, the former who died after being a part of the "Holy Sword Project" and the latter killed by Vampire hunters. (Yuuto's past Volume 3, Life.1 - Life.3; Gasper's past Volume 4, Life.1 - Life.2) - She entered Kuoh Academy two years before the series along with Akeno, Sona, and Tsubaki, reviving the abolished Occult Research Club which is used as a base for her servants and became its president. (Pre-series background, context from Volume 1) - Rias and Akeno went on the Kyoto trip during their second year, and Rias enjoyed every moment of it, however, they didn't plan a proper schedule so therefore there were places that she wasn't able to visit like the Nijou-jou. Rias was so upset that she stomped her feet at the railway station. (Past trip mentioned Volume 13, Life.1 & Life.4) - Also during their second year, Rias and her club organized a haunted house for the school festival and even used real ghosts as she requested a friendly Youkai to look for jobs to plan the decorations. This, however, got them in a lot of trouble with Sona who scolded them for using the real thing. (Past event mentioned Volume 14, Life.2) Powers & Abilities: - Great Demonic Power: Like Sirzechs, Rias inherited exceptional demonic power from her parents and has great talent and skill in using it, even by the standards of a High-Class Devil. (Baseline from Volume 1) After Issei transferred power to her, her demonic power increased to where it rivaled an Ultimate-Class Devil, shaking the ground, and being able to mildly injure the Cadre Kokabiel (Volume 3, Life.4 / New Life). Azazel noted that even without training, Rias has the potential to become one of the highest class devils using natural talent (Volume 4, Life.4). Rias has further improved her demonic power through dedicated training and eventually became an Ultimate Class Devil (Developed over series, likely solidified post-Volume 22 / Shin DxD). She was capable of overpowering Ultimate-Class Devils wounded by Crom Cruach (Later volumes, likely post-Volume 22 / Shin DxD), and while in her Balor Princess Form could keep up with Fenrir at 80% percent power (Shin High School DxD Volume 2). - Power of Destruction (滅びの力, Horobi no Chikara): (Used from Volume 1, Life.4 onwards) - Extinguished Star (消滅の魔星, Ikusutinguisshu Sutā): (Debuted Volume 10, Life.4) - Castling: (Used Volume 2, Life.4) - Oppai Beam (おっぱいビーム, Oppai Bīmu): (Debuted Volume 19, Life.2) - Healing: Rias is capable of healing others using her demonic power, and skilled enough that she can continue the process while asleep. It requires her embracing the injured person and both parties to be completely nude in skin to skin contact for better effectiveness, although it takes the better part of a night to take full effect. She has shown to be able to heal fatal wounds such as when Issei was struck by a Light Weapon. (Used Volume 1, New Life; details mentioned) - Transformation: In True High School DxD Volume 3, she can use her demonic power to change the color of her hair from crimson to blonde. - Expert Magician: Rias is adept in Devil Magic, using it for a variety of purposes enhanced by her demonic power, being one of the magic specialists of her peerage alongside Akeno. (Demonstrated throughout series from Volume 1) - Defensive Magic: Rias can create several barriers to protect herself and her servant, such as from Katerea's self-destruction spell during the Three Factions Conference. (Volume 6, Life.5) - Memory Manipulation: Rias has shown that she has skill in memory alteration, using it on Issei's parents. (Volume 1, Life.2) - Summoning Magic: Rias is capable of summoning her bat-like familiar. (Used occasionally, likely early volumes) - Enhanced Durability: Rias has shown great tolerance to damage and pain, as she was going continuing to fight Regulus and remain in the Rating Game, though she was nearly defeated due to blood loss. (Volume 10, Life.4) - Keen Intellect: Rias is a very intelligent and knowledgeable woman, due to being naturally gifted as well as her aristocratic education as the heiress of the Gremory Clan since childhood. When running the Occult Research Club, she is shown to be knowledgeable on occult topics such as supernatural beings like Youkais, Devils, Angels and Fallen Angels. (Demonstrated from Volume 1) - Expert Tactician: Though outsmarted several times throughout the series, Rias has proven herself to be an excellent tactician and has saved her team along with others many times due to her profound intellect and her ability to handle unexpected difficulties calmly. Indra also acknowledged Rias as a capable leader and strategist even without Issei's support. (Demonstrated throughout; Indra's acknowledgement later volumes, Post-Volume 22 / Shin DxD) - Master Negotiator: Rias is shown to be very talented in negotiations as she could convince Rossweisse to join her peerage by offering her better working conditions and a better salary compared to her previous job in Valhalla (Volume 7, New Life), and while during the Azazel Cup, she was able to convince Vasco Strada to join her team after he declined all prior invitations to participate in the Cup by appealing to his warrior spirit and offering to restore his youth without using Devil's demonic power (Shin High School DxD Volume 1, Life.1). She also managed to recruit Crom Cruach for her team in the Azazel Cup by using his love for fighting strong opponents and his favorite food as payment (Volume 24, Life.1). - Other Skills: As a High-Class Devil, more so the Gremory Heiress, Rias learned a wide arrange of different skills.

(Skill shown occasionally; "Four Heavenly Kings" status likely later volumes, e.g., Volume 14+) - Master Dancer: As a Devil noble, Rias is highly skilled in social dancing. During her and Issei's dancing trial in the ruins of connection, she could dance beautifully with Issei, even leading him in the parts he is inexperienced in to pass the trial.

(Explained Volume 8, Extra Life)

Appearance: Akeno is a beautiful young woman with a voluptuous figure, very long black hair and violet eyes. Her hair is usually tied in a very long ponytail, reaching all the way down to the floor with two strands sticking out from the top and sloping backward, with an orange ribbon keeping it in place. (Her general appearance is established from her introduction in Volume 1, Life.1.) Like most of the girls at Kuoh Academy, she wears the customary Kuoh Academy girls' school uniform, along with black calf-length socks. (Her school attire is standard from Volume 1, Life.1.) As revealed in the visual book with her data, her body measurements are B102-W60-H89 cm B40-W24-H35 in. Her body weight is 54 kg 119 lbs while her height is 168 cm (5 feet 6 inches). In the anime, during battles, she often transforms her clothes into a traditional miko attire, consisting of a white haori with red accents, a red hakama, and a pair of zōri with white tabi. (While she does have the ability to manipulate her clothing into a Miko outfit, referenced by her title "Priestess of Thunder", its frequent use in battle is more prominent in the anime adaptation than consistently detailed in the light novels.) After Akeno has revealed her Fallen Angel side in front of Issei, she has one Devil wing and one Fallen Angel wing. (This unique wing configuration is revealed after she confronts her heritage during the events of Volume 4, Life.3.) As the series progressed and she came to terms with her fallen angel powers, her wings increased to six, at first, because of the aid of Azazel's bracelets, (She uses the bracelets provided by Azazel to achieve her six-winged Fallen Angel Mode starting in Volume 7, Life.3) then eight, resembling a High-Tier Fallen Angel. (She achieves eight wings naturally, without the bracelets, later in the series, solidifying around Volume 22, Life.2 or Volume 23.) Personality Akeno is first seen to be a very elegant and gentle woman with refined lady etiquette, embodying the principals of the ideal Japanese woman: "Yamato Nadeshiko". However, underneath her calm, noble and dignified atmosphere, Akeno is shown to be highly sadistic in battle and doesn't show any mercy or remorse towards the enemies she slays, casually keeping up her smiling elegant persona over an enemy's death and showing an expression of pleasure and lust upon delivering them pain. (Her Yamato Nadeshiko persona is present from Volume 1, Life.1, while her sadistic side in combat is hinted at early on and becomes more explicit during battles like the one against the Cerberus in Volume 1, Life.4 and the Rating Game in Volume 2, Life.4.) Despite her sadism, Akeno is very kind, acknowledged by Rias and Issei. Before meeting Rias, Akeno would help people by purifying evil spirits for a living. (Her underlying kindness is consistently shown in her interactions with her friends. Her past purifying spirits is part of her backstory revealed in Volume 4, Life.3.) As a result of seeing her mother being killed in front of her eyes and her father being unable to save her, Akeno developed a hatred for Fallen Angels, including a sense of self-loathing towards her own Fallen Angel nature, for it was the reason her beloved mother was killed by the Himejima Clan, which lead her to sever ties with her father, going into exile before being saved by Rias after Akeno's maternal relatives nearly killed her. (The details of her mother's death, her resulting trauma, hatred for her heritage, and estrangement from her father are central to her character arc revealed in Volume 4, Life.3.) Due to this reason, she empathizes with those who have suffered under the hands of Fallen Angels like Issei and Asia, who were manipulated and killed by the Fallen Angel Raynare, and was worried that Issei would dislike her due to her Fallen Angel nature. (Her empathy and worry about Issei's reaction are shown in Volume 4, Life.3.) However, she fell in love with him after he told her that he still liked her. (Issei's acceptance and her subsequent deepening feelings occur at the end of Volume 4, Life.3.) With Issei's help, she was able to overcome the sadness of her mother's death and reconcile with her estranged father, renewing their familial bond. (The reconciliation with Baraqiel, facilitated by Issei, takes place in Volume 7, Life.3.) Due to Issei helping her and Baraqiel in their reconciliation, Akeno's love for him deepened considerably as she confessed her feelings for him. (Her confession happens shortly after the reconciliation in Volume 7, Life.3.) While Akeno originally had no interest in dating men due to her past, she began to take an interest in Issei, thinking of him as a cute junior and that interest intensified after seeing his determination in the Rating Game against Riser Phenex and his actions during Rias' engagement ceremony, where he defeated Riser Phenex. (Her initial lack of interest and growing attraction towards Issei are developed through Volumes 1 and 2, culminating after the events of Volume 2, New Life.) She has stated that Issei is the first boy she has ever felt such feelings for as she is shown to have a desire to further her relationship with him. She also loves to tease Issei and Rias, as she loves to make Rias irritated by flirting with Issei stemming from her playful sadistic side. (Her teasing behavior is prominent from Volume 1 onwards.) Akeno has also stated that she has some masochism in her as well, as she is only masochistic towards Issei in contrast to her sadistic nature in battle. (Her masochistic tendencies towards Issei are revealed more explicitly around Volume 5 and Volume 7.) She is shown to be quite vulgar, flirting with Issei as such and doesn't care if Rias knows or saw her doing the act as she tried to have sex with him (Her attempts to seduce Issei become more direct from Volume 3 onwards) while also trying to help Issei further his relationship with Rias, but does care enough to not steal him away from her as she even helped Issei confess to Rias. (Her support for Issei and Rias' relationship, despite her own feelings, is shown leading up to Issei's confession in Volume 10, Life.5.) After falling in love with him, she becomes very seductive and is obsessed with having an affair with Issei whenever she finds a chance, which is often interrupted by Rias and some others. (This behavior intensifies post-confession, particularly from Volume 11 onwards.) She also has a emotionally weak side to her once she removes her mask of being an Onee-Sama, what is left is her true side of "depending" on a man, which is generally Issei and her father Baraqiel after reconciling with him. (Her dependence is most starkly revealed after Issei's apparent death in Volume 11, New Life, where she loses her composure completely.) After her beloved mother was executed, she was deeply traumatized and heartbroken for years until she found closure by reconciling with her father. If danger arises to the people she cares about, she will become depressed or it can also lead to a rise in her tension. The latter occurred when Issei was injured in the Rating Game between the Sitri and Gremory groups (Volume 5, Life.5), and the former when Issei was thought to be dead in the Dimensional Gap (Volume 11, New Life). Despite being seductive toward Issei and acting like a mature young woman, Akeno is still innocent and emotional towards love and acts like a girl her age whenever she is on a date with Issei. (This contrast is shown during her date with Issei in Volume 5, Life.4.) However, this still does not stop her from being seductive and flirting with Issei. Despite being seen as calm and clear, Akeno does get jealous like the other girls and will fight for Issei. (Her jealousy, while often masked by teasing, becomes more apparent in later volumes as the harem dynamic solidifies.) History: Akeno is the only child of Shuri Himejima, a Shinto priestess from the Himejima Clan and Baraqiel, a Fallen Angel and one of the leaders of the Fallen Angel organization, Grigori. As a child, Akeno was close to her mother as her father was mostly away on missions and fell into despair when she witnessed her mother's death, blaming Baraqiel for not being able to protect her. After the death of Shuri, Akeno stayed with her mother's relative before being kicked out due to her Fallen Angel blood. (Her parentage and early history are revealed in Volume 4, Life.3.) At the tender age of 10, without food or money, Akeno journeyed throughout Japan using her skills to purify evil spirits that she learned from her mother in order to survive, doing so for a year and a half. When she stumbled into a certain town, Akeno indirectly saved a human that was contracted with a Devil from the Gremory Clan. Fearing that the Devil would kill her due to her Fallen Angel heritage, Akeno decided to hide from them. Later, while trying to leave the town, Akeno was suddenly attacked by her relatives from the Himejima Clan who came to kill her. Before her Grand-Uncle Suou Himejima could land the decisive blow, Rias, and her father's Bishop, Heinrich Cornelius Agrippa, appeared and talked Akeno's family out of killing her with two conditions; first Akeno is to never enter the territory under the Himejima Clan and second, to always stay beside Rias. She then moved into the Gremory Palace where she was taught various things from studies, to how a lady should act as well as deepening her bonds with Rias, becoming her best friend in the process. She had also become acquainted with Sona Sitri around this time. (Her rescue by Rias and the conditions set by the Himejima clan are detailed in Volume 4, Life.3.) Upon entering Junior High, Rias received her Evil Pieces and made Akeno her first servant. (Mentioned as background information, likely around Volume 2 or Volume 4.) Two years before the series, she entered Kuoh Academy alongside Rias and helped her in re-establishing the Occult Research Club becoming its Vice-President. (Established context from Volume 1.) Akeno and Rias went to the Kyoto trip during their second year, Rias enjoyed every moment of it, however, they didn't plan a proper schedule and therefore there were places that she wasn't able to visit like the Nijou-jou, Rias was so upset that she stomped her feet at the railway station as Akeno tried to calm her down. (Past trip mentioned during the main Kyoto trip arc, Volume 13, Life.1 & Life.4.) Also during their second year, Akeno and Rias organized their club as a haunted house for the school festival, they even used real ghosts as Rias requested friendly Youkai looking for jobs to plan the decorations. This, however, got them in a lot of trouble with Sona who scolded them for using the real thing. (Past event mentioned during Volume 14, Life.2.) Powers & Abilities: - Great Demonic Power: Akeno has great potential in using demonic power, comparable to her King despite being a reincarnated Devil, being the second strongest in the peerage. Riser acknowledged that, pre-training, she was the only one among Rias' peerage who could face his peerage. (Riser's acknowledgement in Volume 2, Life.4.) She became one of the first three to be promoted to Middle-Class, with Azazel stating that she now rivals High-Class Devils. (Promotion occurs in Volume 12, Life.5.) Akeno enhanced her powers to the point of being able to defeat an army of mass-produced Evil Dragons. (Demonstrated during the Evil Dragon War, Volume 21.) Akeno is able to use her demonic power to create a special technique that allows devils to move freely within shrines and temples without any drawbacks. (This technique is likely related to her Himejima heritage and developed later, potentially mentioned around Volume 13 or later.) - Elemental Demonic Power: Akeno excels in using natural elements such as ice, fire, and water, but she specializes in lightning. She is able to create thunder clouds using her demonic power, making lightning bolts rain down on her opponents. She could freeze Cerberus' flames in an instant (Volume 1, Life.4) and target ice spears at her opponents. Much like her Holy Lightning Dragon, Akeno can also form Asian Dragons out of fire and ice, sending them at her enemies. (Elemental dragon forms shown in later volumes, e.g., Volume 16 onwards.) - Lightning Manipulation: Akeno originally specialized in lightning demonic power alone before she began using her Holy Lightning ability, where she imbues it with the power of light. Even before combining it with the power of light, Akeno's strongest lightning bolts were powerful enough to destroy the Kuoh Academy gymnasium. (Demonstrated during training/early fights, e.g., Volume 1 or Volume 2.) Her strikes are shown to be capable of inflicting paralysis and inducing great pain on opponents. - Fire: Akeno is seen to can perform Fire Demonic Power through Asian Dragon forms. (Fire dragons mentioned alongside ice dragons, likely Volume 16 onwards.) - Water: Akeno has shown to be able to summon a vast amount of bodies of water, large enough to fill a swimming pool. (Likely demonstrated during training or specific Rating Game scenarios, harder to pinpoint a single volume without more context, but fits her elemental control.) - Ice: Akeno is capable of freezing her target and create ice into spikes and projectiles. She is shown creating a blizzard that instantly freezes even fire. (Freezing Cerberus's flames in Volume 1, Life.4 is a prime example. General ice manipulation shown throughout.) - Hypnosis: Akeno has shown the ability to hypnotize others as she used it on her college friends to keep Issei's identity a secret while introducing him as her boyfriend. (This occurs in True High School DxD Volume 1, Life.2.) - Cloth Manipulation: Usually when Akeno needs to use all of her magic power, she alters her clothes into a Shinto priestess attire that gave her the epithet, "Priestess of Thunder". She also uses this to repair hers or the clothes of others. (The transformation into Miko attire is tied to her epithet, mentioned early on. Repairing clothes is a minor application.) - Enhanced Magic Power: As a Queen, Akeno can strengthen her magic and demonic powers using the Bishop aspect, which she has shown to be the most adept at using in combat. (The Queen piece granting Bishop traits is fundamental to her role, explained around Volume 2.) - Great Light Power: As a half-Fallen Angel daughter of Baraqiel, Akeno also inherited great light power, mainly in the form of Holy Lightning which she continued to improved through diligent training, her overall power strengthen to the point of gaining six fallen angel wings which later increased to eight. (Her light power potential is revealed in Volume 4, Life.3, and her development is a major arc.) - Holy Lightning (雷光, Raikō): Akeno's signature ability that she inherited from her father Baraqiel. Akeno combines the power of light and lightning to create Holy Lightning. Akeno can make high-density lightning strikes on her opponents. (She begins actively using Holy Lightning after reconciling with her heritage and father, starting prominently in Volume 7, Life.3.) - Fallen Angel Mode (堕天使モード, Datenshi Mōdo): A special form, achieved through Akeno making her Holy Lightning blood denser. In this form, she gained six Fallen Angel wings, strengthening herself, making herself appear more like a Top-Tier Fallen Angel. At first, Akeno needed special bracelets created by Azazel, (Achieved with bracelets in Volume 7, Life.3) however she later became able to enter this state at will. (Achieves it naturally later, likely around Volume 10 or 11.) Akeno's strength increased to the point of being able to gain a total of eight wings. (Eight wings achieved later, around Volume 22 or 23.) - Holy Lightning Dragon (雷光龍, Raikōryū): Due to her constant draining of Issei's Dragon aura, she has gained the ability to shape her Holy Lightning into the form of an Asian Dragon, which can move as if it was alive. (Debuts in Volume 16, Life.1.) It has been shown to be powerful, devouring large fragments of rocks and erasing one of Grendel's fireballs. She became capable of creating five of them at once, (Demonstrated in Volume 21, Life.1) each of which are described as having a dense aura. (Described during the Evil Dragon War, Volume 21.) - Senjutsu: Akeno can use senjutsu to a limited degree to manipulate her presence and avoid detection. (Her ability to use Senjutsu for stealth is mentioned, likely tied to her training and Himejima background, possibly noted around Volume 13 or later.) - Enhanced Strength and Defense: As a Queen, Akeno possesses enhanced strength and defense through the Rook trait of her Queen piece, but due to Akeno never resorting to physical confrontations, it's unknown how her physical prowess compares to Koneko. (Standard Queen piece abilities.) - Enhanced Speed: As a Queen, Akeno has the Knight speed enhancement through her Queen piece. Akeno was capable of evading many of Zhu Bajie's attacks with ease. (Evading Zhu Bajie occurs during the Journey to the West arc, Volume 19, Life.3.) - Expert Magician: Akeno has shown herself to be skilled in the use of magic with her, Rias and Rossweisse being the top magic type specialists in the Peerage (before Rossweisse left). Her magic abilities are enhanced through the Bishop trait of her Queen piece. She has a strong affinity for Shinto Magic, stemming from her Himejima lineage as she could purify evil spirits as a child and later summon legendary Onis. (Her magic skill is evident throughout. Shinto affinity mentioned with her backstory in Volume 4, Life.3. Oni summoning developed later.) - Summoning Magic: Akeno has some skill in summoning magic, being able to instruct Asia in its use. She is shown to summon up to six oni familiars that are useful in recon. Her ability to summon creatures was strengthened after she entered the Himejima household and strengthened her Himejima blood, thus allowing her to summon legendary Youkai like Ura and Ibaraki Douji. (Summoning legendary Oni likely occurs post-reconciliation with the Himejima clan, Volume 22 onwards.) - Defensive Magic: She has been shown to be able to use magic to strengthen the power of her defense by focusing on the Rook trait of her Queen piece to protect herself as well as others from powerful attacks. (Standard application of Queen piece versatility.) - Teleportation Magic: Akeno can use teleportation magic to teleport herself and others. (Standard Devil ability.) - Purification: Akeno can use Shinto spells to purify evil spirits which she learned from her mother. (Mentioned in her backstory, Volume 4, Life.3.) - Extrasensory Perception: Kiba has noted that Akeno has particular skill in reading different kinds of energy flows, being able to tell how the spirits of Kiba's old friends were released from the orb (Volume 3, Life.3), and sensing Vali's arrival (Volume 4, Life.4). - Stealth Expert: As mentioned by Issei and Rias, Akeno has developed a skill to sneak behind people without leaving any presence. Rias mentioned that Akeno has learned a skill that allows her to avoid detection from Koneko's Senjutsu sensing ability. (Her stealth is noted frequently, often used for teasing or surprise attacks.) - Master Chef: Akeno is an extremely skilled cook, cooking delicious foods such as nikujaga, which reminded Baraqiel of Shuri. (Cooking skill shown, Nikujaga scene during reconciliation in Volume 7, Life.3.) Her cooking skills are enough for her to be known as one of the Four Heavenly Kings alongside Miki, Rias, and Asia, cooking delicious foods, often competing with Rias over Issei. (Cooking competition is a recurring theme, particularly in later volumes.) - Flight: Uniquely, Akeno has two different methods of flight, the first being her bat-like wings as a reincarnated devil or fallen angels wings due to her heritage. (Both wing types available post-Volume 4.) Equipment - Queen Piece: (女王の駒, Joō no koma): Akeno was reincarnated using the Queen Piece, which grants her the characteristics of a Rook, Bishop, and Knight. Although, she is more aclined to the Bishop trait, instead of the Rook and Knight. (Reincarnation happened pre-series, piece function explained around Volume 2.) - Bracelets: Golden bracelets engraved with magical characters. An invention by Azazel that assisted the fallen angelisation of Akeno. (Used from Volume 7, Life.3 until she could achieve the form naturally.) - Oni: Akeno has a great affinity with Onis which she inherited from her mother. She made a contract with small onis as well as two legendary Oni, Ura and Ibaraki Douji. (Contracts likely made post-reconciliation with Himejima clan, Volume 22 onwards.) - Oni Mask: Akeno possesses an oni mask, something that she uses to summon two powerful and legendary Oni under her contract. One is Ura, a famous Evil Oni who served as his tribe's leader on Onigashima, while the other is a Daiyoukai, Ibaraki Doujou, who served as Shuten Douji's right-hand man. (Mask used to facilitate summoning, tied to the Oni contracts.) TRIVIA: - Akeno's birthday is on July 21. - The name Akeno means "vermilion red" (朱, ake) and "from" (乃, no). - Akeno's last name, Himejima, means "Princess Island". - Akeno has large breasts due to her Fallen Angel blood. Azazel later states that female Fallen Angels possesses seductive bodies, but notes that for a half-Fallen Angel, Akeno is exceptional. (Azazel's comment likely made around Volume 7 when discussing her Fallen Angel mode.) - Issei called Akeno "Yamato Nadeshiko" which means "personification of an idealized Japanese woman", or "the epitome of pure, feminine beauty". (Issei uses this description early on, e.g., Volume 1.) - In Rating Game fighting-types, Akeno is considered a Wizard-type who is closer to a Technique-type. Akeno inherited her sadistic personality from her mother and her masochistic personality from her father. - It was revealed in Ishibumi's other work, -SLASHDØG-, that Akeno is related by blood to Tobio Ikuse as cousins. - Tobio's grandmother is a member of the Himejima Clan. - Akeno, alongside Asia, have the most familiars in the series with both having six each. (Small Oni, Ura, Ibaraki Douji = 3+ main familiars. Number comparison is meta-knowledge.) - Akeno uploads videos to DeviTube about Japanese traditional performing arts. - Akeno has a driving license. - According to a questionnaire, her favorite type of man is one who is always smiling. - She's proud of her black hair and breasts because they make Issei happy. - She can do everything with ease. - Her weakness is that she's not really good with men. - If she didn't become a Devil, she would have became a priestess at some shrine. - She likes having tea parties with Rias and Sona, shopping, and making pastries. - Her one wish is to go to a deserted island with Issei, so the two of them can enjoy a lifestyle where they spoil each other. - She said if Issei feels like having an affair, he can always tell her. - She begins washing from her chest. - She doesn't put on panties after a shower as a single bath towel is enough for her. - Her erogenous zone is anywhere on her body. - Her hobbies are food research and shopping. - Her favorite thing is Japanese traditional clothing. This is reflected in her wish to wear a shiromuku, a pure-white wedding kimono worn by brides in a traditional Japanese Shinto wedding ceremony for her marriage with Issei. - Among the Gremory peerage, Akeno excels at reading different types of energy flow. (Noted by Kiba in Volume 3, Life.3.)

Appearance: Koneko is a petite girl with white hair and gold eyes. Her body measurements are [B67-W57-H73 cm] [B26-W22-H29 in]. Her weight is [31 kg] [68 lbs]. The front of her hair has two long bangs going past her shoulders and several loose bangs hanging over her forehead, while the back has a short bob cut. She also wears a black cat-shaped hair clip on both sides of her hair, one of which contained the data on artificially making new Super Devils. She usually wears the Kuoh Academy girls' school uniform, without the shoulder cape. Koneko's height is 138 cm (4 feet 6 inches), making her one of the shortest female characters of the series. In her Nekomata form, she grows a pair of white cat ears and a pair of matching white tails, and her pupils become more cat-like. In Volume 24, she gained three tails. In her "Shirone Mode" that she used for the first time in Volume 16, Koneko can make herself grow older, and her attire consists of a short white kimono and a light blue skirt. Her bust size grows significantly larger when in this mode, making her look more similar to her sister Kuroka. Personality: Due to witnessing her sister supposedly losing control over her nekomata power and killing her master, Koneko became traumatized by the event, causing her to become withdrawn into herself and stripping her of most of her emotions. As a result, Koneko originally had a quiet and cold personality, rarely showing any feelings or emotions, even when she was speaking. It is noted that her serious personality is a result of receiving influence from Rias, and it is also antithetical to her sister's mischievous and outgoing personality. She was also the only one in the group who did not initially get along with Issei, often insulting and rebuking the latter for his perverted nature, although she reveals that she respects him for never giving up and considers him a hard worker. She shows the most concern for her comrades when they are in trouble, often lending her strength in fights. Koneko apparently has a problem with people calling her a midget (although the context of the phrase could be used to be called flat, as in bust size), as shown in her second battle against Freed Sellzen. This may stem from her insecurity about her own small body and bust size. Koneko is also a glutton, food lover and a keen gourmet, as she is frequently seen eating snacks, visiting restaurants and enjoy regional specialties while on food tours. At the end of Volume 5, Koneko experiences a change in her personality after Issei helps her overcome her fear of using Senjutsu and now starts acting like a cat, often ends her sentences with "Nya" (にゃ), and/or showing attraction towards Issei. Her love for Issei grows so much that, at the beginning of Volume 11, she starts to go into her mating season (though this was later stopped by her sister Kuroka). However, she still insults him when his perverted nature gets the better of him (at least when it isn't directed towards herself). Koneko has even stated that she enjoys Issei viewing her as a woman. History: Born as Shirone, Koneko is a young Nekomata who is part of a rare species among her kind, called the Nekoshou. She was born from the union between a human father and a Nekomata mother named Fujimai. Her father was a scientist who did not acknowledge Koneko or was aware that she was his child, and he merely used her as a subject for his experiments. Her parents eventually died in an experiment-related accident. However, her older sister Kuroka, omitted the truth and any other details about them from Koneko to protect her. After losing her parents, she and her sister were later taken in by an unnamed Devil from the branch family of the House of Naberius, who reincarnated her sister as one of the members of his peerage. However, Kuroka's power as a Nekomata supposedly soon grew out of control, eventually causing her to kill her master and become a Stray Devil on the run from her pursuers. In actuality, he had planned to experiment on Koneko in his research about creating a Super Devil, causing Kuroka to kill him in order to protect her younger sister. Following the incident and the failed manhunt that came after, Koneko was sentenced to death by the Devils in hopes of preventing another incident like Kuroka's from happening. However, Sirzechs Lucifer, one of the Four Great Satans, protected her and left her under his sister Rias' care. Due to the trauma, she experienced with her sister's betrayal and murder of her master, she fell into a deep depression, eventually robbing her of nearly all of her emotions until Rias helped her out of it. It was around that time Rias gave Koneko her name and made Koneko her servant. Powers & Abilities: - Demonic Power: (Volume 1) As a reincarnated Devil, Koneko possesses the standard suite of demonic powers from her introduction. This includes enhanced physical abilities, extended lifespan, and the capacity to utilize demonic magic and spells, forming the foundation of her combat prowess alongside her unique racial traits. - Senjutsu Expert: (Learned/Developed around Volume 5 onwards; Feat against Gandoma Balam in Volume 24, Life.4) Being a Nekoshou, a rare type of Nekomata, Koneko demonstrates a natural and high aptitude for Senjutsu. She begins to seriously refine these skills under her elder sister, Kuroka, around Volume 5 after confronting her past. Instruction from Magari likely comes later. By skillfully tapping into Senjutsu, Koneko gains precise control over the flow of ki. This allows her to significantly enhance the impact of her physical attacks. She demonstrated this capability by affecting others internally, notably breaking down the formidable magic resistance of Gandoma Balam (Volume 24, Life.4). Furthermore, Koneko can utilize Senjutsu as a sensory tool, allowing her to detect the presence and ki signatures of others (Developed progressively from Volume 5 onwards). - Touki (Fighting Spirit): (Developed from Volume 5 onwards; Surpassed Kuroka mentioned in Volume 24, Life.5) A key application of her Senjutsu is the ability to envelop herself in an aura of pure ki, known as Touki. This dramatically boosts her inherent strength, defensive capabilities, and movement speed. Through dedicated training (starting Volume 5), she developed the capacity to generate a truly tremendous Touki aura, reaching a level where her raw physical power, when augmented this way, could even surpass that of her highly skilled older sister, Kuroka (Volume 24, Life.5). - Healing: (Developed from Volume 5 onwards) Koneko can channel ki through Senjutsu for restorative purposes. This likely developed alongside her general Senjutsu mastery starting around Volume 5. This allows her to mend physical injuries, alleviate mental fatigue, replenish stamina, and even restore depleted life-force in others. - Bouchujutsu (Bedroom Method): (Acknowledged capability, likely discussed Volume 16 onwards) A more specialized, potent, and rapid healing technique derived from Senjutsu principles. While Koneko has openly acknowledged her ability to perform this technique (likely discussed sometime after mastering Senjutsu and understanding its deeper applications, possibly Volume 16 or later when life-force issues for Issei are prominent), she has not yet actually performed Bouchujutsu. - Kasha (Burning Chariot): (Debuted in Volume 16, Life.3) Tapping into her Nekomata heritage via Senjutsu, Koneko can manifest multiple large, ethereal wheels wreathed in potent white flames. This ability is prominently used while in her Shirone Mode (Debuted in Volume 16, Life.3). - Sealing: (Learned and used in Volume 17, Fake Hero) Under Kuroka's guidance, Koneko learned a practical and vital application of Senjutsu specifically designed as a countermeasure against Evil Dragons. By utilizing a specialized jewel derived from Issei's Scale Mail armor, she can channel her Senjutsu to forcefully seal the souls of these powerful beings within the jewel. This technique was successfully employed to capture the soul of the Evil Dragon Grendel (Volume 17, Fake Hero). - Presence Suppression: (Developed from Volume 5 onwards) Koneko has demonstrated the ability to apply her Senjutsu control to consciously suppress her own ki signature and physical presence, likely developed as part of her overall Senjutsu training (Volume 5 onwards). - Youjutsu User: (Innate; Actively developed from Volume 5 onwards) As a Nekomata, Koneko possesses the innate ability to wield Youjutsu. She begins actively learning and honing these skills (around Volume 5 onwards), receiving instruction from both Kuroka and Magari. She often integrates Youjutsu techniques seamlessly with her Senjutsu applications. - Immense Strength: (Volume 1 - Baseline Rook trait; Feat vs Viser in Volume 12, Life.4; Defeated Xuelan in Volume 2, Life.4; Amplified by Nekomata Lvl 2 post-Volume 5; Damage vs Gandoma in Volume 24, Life.4; Exceeded Kuroka with Touki in Volume 24, Life.5) Even before factoring in her Senjutsu, Koneko's power is heavily augmented by her assigned Evil Piece trait: Rook (Present from Volume 1). She has been consistently shown lifting and throwing opponents and objects significantly larger and heavier than herself. Notable feats include effortlessly lifting the large Devil Viser before forcefully knocking him a considerable distance (Volume 12, Life.4), and punching through durable materials. She proved her strength in combat by defeating Xuelan (Volume 2, Life.4). Upon achieving Nekomata Level 2 (Post-Volume 5 training), her strength was further amplified, enabling her to inflict significant damage upon Gandoma Balam (Volume 24, Life.4). When combining her Rook-enhanced strength with her potent Touki aura, her physical power is stated to exceed even Kuroka's (Volume 24, Life.5). - Immense Durability: (Volume 1 - Baseline Rook trait) Complementing her immense strength, Koneko's Rook trait also provides her with extraordinary physical durability (Present from Volume 1). Most conventional attacks often have minimal effect. - Immense Speed: (Volume 1 - Baseline Nekomata trait; Countered Xuelan in Volume 2, Life.4; Augmented by Touki/Lvl 2 post-Volume 5; Third tail boost in Volume 24, Life.5) While Rooks are typically known for strength and defense over speed, Koneko, being a Nekomata, naturally possesses enhanced agility and swiftness (Present from Volume 1). This inherent speed enabled her to effectively react to and counter the rapid kicks of the skilled martial artist Xuelan (Volume 2, Life.4). By further augmenting her speed with Touki or activating her Nekomata Mode Level 2 (Post-Volume 5 training), she can achieve bursts of velocity fast enough to surprise opponents. After awakening her third tail, her base speed increased to the point where she could move faster than Kuroka could track her presence (Volume 24, Life.5). - Enhanced Senses: (Volume 1 - Baseline Nekomata trait; Smelled Fallen Angels in Volume 1, Life.3) As is characteristic of her Nekomata lineage, Koneko possesses naturally heightened senses (Present from Volume 1). This was demonstrated early on when she was able to accurately smell the presence of Fallen Angels hiding within a church (Volume 1, Life.3). - Transformation: (Volume 1 - Basic ear/tail manifestation) Koneko can freely manifest or retract her Nekomata features at will (Volume 1). Manifesting these features grants her full access to her innate Nekomata abilities and Senjutsu potential. - Nekomata Mode Level 2: (Achieved during training in Volume 5, Life.3) A powered-up state achieved through intense Senjutsu training. In this mode, Koneko grows a second tail and cloaks herself in a powerful Touki aura, granting a temporary but explosive surge in power. - Shirone Mode: (Debuted in Volume 16, Life.3) An advanced transformation where Koneko utilizes ambient natural ki to temporarily mature her body into an adult form. This mode grants her complete access to her Nekomata powers, including Kasha, and embodies purification. - Master Hand-to-Hand Combatant: (Volume 1 - Baseline skill; Defeated Xuelan in Volume 2, Life.4; Integrated Senjutsu post-Volume 5; Defeated Evil Dragons in Volume 16; Defeated Grendel clone in Volume 17, Fake Hero; Fought Kuroka e.g., Volume 5, Life.3 / Volume 11, Life.1) Koneko is an exceptionally skilled practitioner of close-quarters combat (Shown from Volume 1). She employs a versatile fighting style. Combined with her Rook-enhanced physicality, she proved capable of defeating trained opponents like Xuelan (Volume 2, Life.4). After embracing her Nekomata heritage and integrating Senjutsu into her combat style (Post-Volume 5 development), her physical attacks became even more dangerous. Continuous training allowed her to overcome formidable foes such as mass-produced Evil Dragons (Volume 16) and a powerful clone of the Evil Dragon Grendel (Volume 17, Fake Hero). She has also demonstrated the ability to fight on par with Kuroka (Various encounters, notably after accepting her power in Volume 5, Life.3 and later confrontations like Volume 11, Life.1). - Flight: (Volume 1) As a standard ability for all Devils, Koneko can manifest Devil wings, allowing her to fly freely (Shown from Volume 1). TRIVIA: - Koneko's birthday is November 23, according to the Sodom Press Data File on her. - Koneko's name translates to "Kitten" and "little cat", in reference to her being a Nekomata. - Koneko's real name, Shirone, means "White Sound", in reference to her hair and tail color. - Koneko's last name, Toujou, means "Castle", in reference to her being a Rook (in chess, the rook piece is a castle's turret). - She has the same last name as Sae "Toujou" from Slash/Dog. - In Rating Game fighting-types, Koneko is considered a Power-type. - Koneko plays the mascot character, "Hellcat-chan", in Breast Dragon Emperor Oppai Dragon. - Koneko has a broad range of interests which include anime, drama, music, and comedy shows. - Koneko loves rap music and is a fan of Salamander Tomita, who is a kappa rapper. - Koneko is one of the two servants of Rias who had been given a new name by the latter; the other one being Yuuto. (Koneko's renaming is part of her backstory revealed in Volume 5, Life.3. Yuuto's renaming is part of his backstory in Volume 3, Life.3.) - Koneko's name, along with the fact that she wears gloves with cat paw prints and is quite agile, were all allusions to her being a Nekomata before the fact was revealed. (Her true nature is revealed in Volume 5, Life.3.) - Koneko is the sixth to become engaged to Issei Hyoudou. (Engagement occurs in Volume 24, Life.5.) - She calls herself "Daineko" in her gender-swapped form. - Daineko translates to "big cat" in reference to her being a large man when her gender was swapped in the short story "Stop! Yuuto-kun!" - Koneko likes to enjoy watching food reviews and game videos on DeviTube, as well as live streaming games. - Koneko's job requests as a Devil are mainly cosplay requests for photo shoots or playing games with her clients. (Mentioned in Volume 13, Extra Life.) - The nature of her contract requests coincide with that of Asia Argento. (Mentioned in Volume 13, Extra Life.) - According to a questionnaire: - Koneko’s favorite type of man is one who is a very kind person. - She's proud of her ears and tail because people say they are cute. - Her special skill is eating a lot and not getting fat. - She's not good at doing naughty things. - If she didn't become a Devil, she would be living in an unpopular place somewhere. - She likes going to cake shops. - Her one wish is for her breasts to grow bigger. (A recurring desire mentioned humorously throughout the series, e.g., Volume 7 onwards.) - She said about Issei not to be too picky and to please be kind to her forever. - She starts bathing from her tail. - She has white panties with a hole in for her tail. - Her erogenous zone is her stomach. - Her hobbies are collecting cat accessories and trying food at various restaurants. - Her favorite thing is hot milk mugs. - Kuroka and Koneko's father was a Buddhist. Hence, both of their parent's souls are in the afterlife associated with Buddhism, and are subject under Great King Enma. (Mentioned in Volume 24, Life.3.) - In initial story draft, Koneko hated vampires, because one vampire from Khaos Brigade killed her family. Thus, Koneko had bad relations with Gasper. Issei had to reconcile them in Light Novel Volume 4.

Yuuto Kiba is a third-year high school student at Kuoh Academy in Class 3B and the school's "pretty boy" who is adored by many female students and hated by other male students. He is Rias' Knight piece. Yuuto is a handsome young man with short blond hair, blue eyes and a mole underneath his left eye. Yuuto is overall an upbeat person and cares deeply for his comrades. He's also a very polite and friendly individual, even considering other's initial dislike towards him. As a Knight, he has pride, chivalry, dignity, and honor befitting one, and is shown to enjoy fighting fellow swordsmen like Karlamine. Yuuto has an immense hatred for Excalibur and other holy swords due to the trauma he experienced in his childhood. Yuuto's requests usually come from older women and working women who consult their stress with him or by having Yuuto cook for them.

Appearance: Asia is a beautiful young girl with long blonde hair and green eyes. Her body measurements are B83→85-W55-H81→83 cm; her height is 155 cm 5 feet 1 inch and her body weight is 44→45 kg 97→98 lbs. Her hair flows all the way down to her back, with split bangs over her forehead and a single strand sticking out from the top and sloping backward. (Her initial appearance is described upon her introduction in Volume 1, Life.3.) Her former main attire consisted of a dark teal nun outfit with light blue accents, a white veil over her head with light blue accents, a brown satchel slung on her right hip (where she holds her Bible), and brown boots with black straps in an X-shaped pattern. (Her attire as a nun is described in Volume 1, Life.3.) She also wore a silver cross necklace around her neck (she was later forced to remove it after becoming a Devil). (The cross is mentioned in Volume 1, Life.3, and its removal upon reincarnation is implied/occurs off-screen before her reintroduction as a Devil in Volume 1, New Life.) Upon transferring to Kuoh Academy, she wears the Kuoh Academy girls' uniform, albeit with a black sweater vest over her dress shirt in place of the cape and corset which has become her current main attire. (Her school uniform is first seen when she transfers in Volume 2, Life.1.) Personality: Asia is extremely shy, innocent and fairly inexperienced in things like socializing. (This is evident from her first interactions in Volume 1, Life.3 onwards.) As a former nun, Asia is a devout Christian, despite being reincarnated as a Devil, Asia still believes in God and follows his teachings such as praying to him and reading the Bible, which would usually result in her getting severe headaches. (Her continued faith and the resulting headaches are shown starting in Volume 2, Life.1.) Asia has a strong kindness, even when she was still a human, she harbored no hate towards Devils and treated everyone equally, regardless of what they were. (Her kindness towards Issei, a Devil at the time she met him, is shown in Volume 1, Life.3.) Azazel noted that her unconditionally kindhearted nature forces her Sacred Gear to heal even enemies, as she is incapable of turning a blind eye to the suffering of others. (Azazel comments on this aspect of her power, likely around Volume 4 or Volume 5 during discussions about Sacred Gears.) Asia was also in deep shock when she learned from Kokabiel that the God of the Bible was killed during the Great War. (Her reaction occurs during the Kokabiel incident in Volume 3, Life.4.) While initially having difficulty adjusting to her new life as a Devil, she has stated that she has found more important things than her faith in God, those things being her new friends, comrades as well as Issei's parents and Issei himself. (Her adjustment and shifting priorities are a gradual process, clearly articulated by Volume 4.) Asia is noted to be a very pure individual as people are drawn to her and that she is easily liked by others. (This trait is consistently demonstrated.) Her charm and purity is such as that she was able to tame Rassei, a Sprite Dragon despite being a Devil as normally Sprite Dragons aren't tamable by Devils and are only tamable by those with pure hearts. (Occurs during the Familiar arc in Volume 2, Life.3.) Azazel noted that she had outstanding talent for taming Dragons, as after receiving Ophis' blessing, she was able to form a contract with Fafnir, one of the Five Great Dragon Kings. (Ophis's blessing and the pact with Fafnir happen in Volume 12, Life.1.) After she managed to tame 4 mass-produced Evil Dragons, her name was spread in the world of Dragons due to the fact that only Evil Gods were able to tame Evil Dragons, as she became known as the Dragon Priestess (龍の巫女, Ryū no Miko) among Dragons. (Taming the Evil Dragons occurs in Volume 17, Life.4, her title spreads afterwards, noted in Volume 18, Life.2.) Due to having to give away her panties each time she wants to summon Fafnir, she has become very embarrassed due to seeing Fafnir eat her panties to the point of escaping from reality, lamenting that she has become associated with panties. (The panty requirement and her reaction begin with the Fafnir pact in Volume 12, Life.1 and become a running gag.) However, after seeing Fafnir's resolve to protect her against Rizevim, she has become a bit less embarrassed by it and can put her shame aside during battle when Fafnir is fighting for her intensely. (Her change in attitude during the Rizevim conflict occurs in Volume 20, Life.3.) Asia has a love of agricultural work as she often does gardening and planting. She has even stated that she would like to live with Issei in the country side of the Underworld and do cropping along with other kind of agricultural work. Asia would become more "bold" in her relationship with Issei when she saw the other girls being more intimate with him and dislikes the idea of being left out. (Her increasing boldness is a gradual development, noticeable from Volume 3 onwards as she competes for Issei's attention.) Due to Issei initially viewing her as more of a sister due to his desire to protect her, he didn't ogle her like he did other women, causing her to be sad and develop a bit of a inferiority complex when it comes to comparing her looks to the likes of Rias. (Issei's initial view and her resulting sadness are themes in early volumes, particularly Volume 3 and Volume 4.) However, she will get jealous and pinch his cheeks whenever he lusts over other girls. (A recurring reaction seen often.) She is shown to desire to be treated as a woman by Issei and to have his erotic behavior directed at her, as she has even shown a desire bear his children, though she ultimately succeeds in this endeavor after the Sports Festival when she kisses him, as following that point, Issei began to view her more as a woman than a little sister. (Her desire is expressed, and the turning point kiss occurs during the sports festival in Volume 14, Life.2.) Asia thinks very highly of Issei and has stated a desire to stay with Issei forever, even being willing to become his servant. (Her devotion is clear from Volume 1, New Life onwards.) Despite being shy, she is shown to be protective of Issei as she will slap someone like Diodora when they insult Issei. (She slaps Diodora in Volume 6, Life.4.) After becoming Issei's servant, she has begun to shown more courage and determination in battle, as demonstrated in the Rating Game against Team Rias Gremory, where Asia stayed behind to fight Crom Cruach alone to allow Xenovia and Irina to proceed ahead as well to preserve Issei stamina, with Crom Cruach admiring her courage and guts. (This occurs during the Azazel Cup in True High School DxD Volume 2, Middle Game.) During the fight, she even displayed the ability to use Magic offensively, in contrast to her past passive self, as she continued to fight Crom Cruach even after Fafnir was defeated, stating that as the servant and future wife of the Red Dragon Emperor, she would keep fighting until the end, which deeply impressed Crom Cruach as he praised her courage and spirit, stating that it was his honor to fight her and Fafnir. (Her actions and Crom Cruach's reaction in True High School DxD Volume 2, Middle Game.) History: In the past, Asia was abandoned by her parents in front of a church as an infant and was raised there. Sometime, during her childhood, she had awakened her Twilight Healing to heal an injured puppy she discovered, which was witnessed by one of the Catholic Church members causing her to become symbolized as the Holy Maiden. But, in all that time she didn't have either friends or people to talk to since most people viewed her as a monster who could heal wounds. (Her backstory is revealed in Volume 1, Life.3.) At some point, Diodora Astaroth devised a plot to have Asia heal him, a Devil, and cause her banishment from the Church with people labeling her as a "witch". With no place to go, Asia had to rely on the Fallen Angels. (Diodora's involvement in her exile is revealed later, confirmed in Volume 6, Life.4.) Powers & Abilities: - Demonic Power: As a Devil, Asia has all the common skills and powers of one, including the power to cast spells. (Standard Devil abilities apply post-reincarnation in Volume 1, New Life.) - Enhanced Magic Power: As a Bishop, Asia can strengthen her Magic and Demonic Powers, which she normally applies onto her Twilight Healing. (The function of the Bishop piece is explained around Volume 2.) - Magic Talent: As a Bishop, Asia has shown great potential in using magic as she was put in charge of forming a barrier by Freed. (Occurs during the Kokabiel incident in Volume 3, Life.4.) Asia is studying under Rossweisse in order to learn summoning and transport magic to help defend herself and increase her combat strength, she can also use Dragon Gate magic circle. (Training under Rossweisse begins after Rossweisse joins in Volume 7, Dragon Gate usage shown later, e.g., Volume 12.) Using her Bishop trait she can enhance her healing abilities with Twilight Saint Affection along with Fafnir's golden aura. (Synergy with Fafnir starts post-pact in Volume 12, Balance Breaker synergy later.) - Summoning Magic: Asia is show to be very adept at summoning magic as she is capable of using it to summon various creatures to assist her and Dragon Gate magical circles to summon her guardian familiar; the Golden Dragon King Fafnir. (Summoning Fafnir begins Volume 12, Life.1.) - Elemental Magic: Asia is capable of using elemental magic; such as fire and wind magic as demonstrated in her fight against Crom Cruach. (Occurs in True High School DxD Volume 2, Middle Game.) - Dragon Tamer: She's shown to have the talent of compatibility and outstanding luck with Dragons, as she made a pact with a baby Sprite Dragon, Rassei, whose race is notoriously untamable. (Occurs in Volume 2, Life.3.) After receiving Ophis' blessing, her compatibility increased, and she made a pact with one of the Five Dragon Kings; Fafnir. (Occurs in Volume 12, Life.1.) Asia was able to make a pact with four mass-produced Evil Dragons who were named Anselmus, Cyril, Gregorios and Simeon, which is an act that only Evil Gods were able to do before. (Occurs in Volume 17, Life.4.) - Praying: Asia is one of the two Devils, the other being Xenovia, that can pray to God without receiving damage in the form of a headache after Issei made a request to Michael to allow them to pray to God. (Request made in Volume 3, Life.5, ability confirmed later, e.g., Volume 4.) - Flight: Being a Devil, Asia can use her wings to fly. (Standard ability post-reincarnation.) Equipment: - Twilight Healing (聖母の微笑, Towairaito Hīringu): Asia's Sacred Gear and her main weapon of choice, she can heal Humans, Devils, Angels, and Fallen Angels alike. (Introduced and demonstrated in Volume 1, Life.3.) Since she has shown no actual combat skills, she relies on her healing abilities as a healer of her team. Asia learned how to expand the range of her healing field and send her healing powers as a projectile, although these are inferior to actual touch. (Range expansion likely developed during training arcs, e.g., between Volume 4-5.) In Volume 11, Azazel has said that she mastered her Twilight Healing more than other possessors in healing powers and time. (Azazel's comment in Volume 11.) She can also create a bow and arrow of healing power, and if the arrow is about to hit an enemy, it will disperse instead of healing them. (Healing arrow technique likely developed later, possibly around Volume 16 or later.) - Twilight Saint Affection (聖龍姫が抱く慈愛の園, Towairaito Seinto Afekushon): Asia's sub-species Balance Breaker. Asia's Balance Breaker takes the form of a Golden Dragon Armor with red jewels that cover her body and grants her a field of absolute defence and protection. For a limited time, Asia can cover a field with tremendous healing energy and can negate any damage from virtually any sources. It does not negate the attack but rather it negates the damage that the attack would inflict. As Fafnir's aura is included as well, it also boasts immense defence on top of the healing ability. Asia can also used it to heal numerous allies at once on a wide range, using it to heal the allied youkais during the Evil Dragon War. (Balance Breaker achieved and used during the Evil Dragon War, Volume 21, Life.3.) - Bishop Piece (僧侶の駒, Sōryo no Koma): Asia was reincarnated using the Bishop Piece, which grants her enhanced magic power. (Reincarnation occurs off-screen between Volume 1, Life.4 and Volume 1, New Life.) - Dragons: Asia had made a pact with Dragons. With the help of Ophis' blessing, Azazel, Rias, Rossweisse, and Akeno, she can make pacts with various classes of Dragons, even higher classes, especially Fafnir the Golden Dragon King. She uses Fafnir and the other four Evil Dragons (that she tamed using Fafnir's skills) to protect herself in order for her to heal her comrades. (Pacts made in Volume 2, Volume 12, Volume 17.) TRIVIA: - Asia's birthday is on May 11. - Asia Argento is named after the famous Italian actress of the same name, daughter of horror director Dario Argento, who is known to have played a number of roles as a nun. - Asia's last name is also the Italian word for "Silver", in reference to the silver cross she once wore prior to being revived into a Devil. Silver crosses are common among the Catholic clergy, particularly exorcists. - Asia's breasts have grown to be nearly the same size as Xenovia's and Irina's. According to Ravel, this is due to a combination of devil physiology, demonic power and Asia's own desires for Issei to see her as attractive. (Breast growth discussion occurs in Volume 23, Life.1.) - Asia is the third girl to become engaged to Issei Hyoudou. (Engagement occurs in Volume 23, New Life.) - Asia wants to have her wedding take place in Japan. (Mentioned in Volume 24, Life.1.) - According to a questionnaire: - Her favorite type of man is Issei. - She's proud of her eyes because Issei says they're beautiful. - Her special skill is being able to recite the Bible and scriptures. - If she didn't become a Devil she would have continued being a Sister. - She likes to go to home improvement stores and 100 yen stores with everyone and she never gets tired of all the products she finds unusual. - Her one wish, is to travel to various places in Japan, because she wants to learn more about it. - She's thankful to the Occult Research Club members for always being so friendly with her. - She loves Issei and will always be there for him. - She begins bathing from her hands. - She has pink, transparent underwear gifted from Kiryuu. - Her erogenous zone is around her collarbone. - Her hobbies are praying and collecting shoujo manga. - Her favorite thing is having a matching umbrella with Issei. - Asia has stated to want five children. - Asia has a hobby for farming and one of her dreams for the future is to engage in agricultural work with Issei in the Underworld. - She also harbours a dream to live in a countryside in the Underworld at a point. (Mentioned in Volume 17, Life 2.) - Interestingly, Asia's four Evil Dragons Anselmus, Cyril, Gregorios, and Simeon are all names of religious figures. - In Rating Game fighting-types, Asia is considered a Support-type who is closer to a Wizard-type. - Asia first noticed that Issei's request to Michael for her and Xenovia to be able to pray was granted during a date with Issei. - During her "date" with Issei in Volume 1, Asia gained a yellow mouse plush doll she named "Racchuu-kun" that resembles Pikachu from Pokemon. (Occurs in Volume 1, Life.3.) - Asia's first-ever meeting with Issei may have been foreshadowing to the relationship between Cleria Belial and Masaomi Yaegaki, as at first, Asia and Issei similarly to Cleria and Masaomi, were forbidden from seeing each other in the same town; Kuoh Town due to the Devil's side and Angel's side still at feuds with each other. (Initial restrictions mentioned in Volume 1, Life.3.) - Asia, alongside Akeno, have the most familiars in the series with both having six each. (Rassei, Fafnir, 4 Evil Dragons = 6). - Asia's job requests as a Devil are usually cosplay requests for photo shoots and playing games. (Mentioned in Volume 13, Extra Life.) - The nature of her contract requests coincide with that of Koneko Toujou. (Mentioned in Volume 13, Extra Life.) - Asia alongside Xenovia, make videos giving expository about Japan's daily school life from a foreigner’s perspective and upload them to DeviTube. Irina is sometimes called in as a guest to which the trio became a popular streaming group. - Asia learned how to ride a bicycle because she wanted to ride with Issei to go on a picnic, as well as ride with Xenovia, Irina and Aika to go shopping. - There's a jinx that all the villains who have hurt Asia have suffered brutal ends and were killed, no matter the series. These antagonists includes Raynare (Killed Volume 1, New Life), Freed (Killed Volume 3, Life.5), Diodora (Killed Volume 6, Life.5), and Rizevim (Killed Volume 21, Life.3).

Gasper Vladi is a cross-dressing male Dhampir, a half-Vampire half-human but was turned into a Devil by Rias Gremory. He has the ability to stop time and is Rias' first Bishop piece. Gasper is an effeminate-looking male with platinum blond hair and pinkish-violet eyes. His hair is styled in short bob cut with several small fringes over his forehead, and he has pointed ears. Kiba describes him as looking like a beautiful girl. Originally a coward and a shut-in with a very shy personality, Gasper likes to wear female clothing, claiming that girls' clothes are cute. He also has a penchant for boxes, carrying one with him all the time. Gasper was born between the Vampire Lord Vladi and a human mother; the latter of whom died shortly after giving birth to Gasper, who was born as a mass of darkness which accidentally cursed his mother and several servants to death. Between the incredible fear of Gasper's true form from the higher ups, his uncontrollable Sacred Gear, Forbidden Balor View, and people's general prejudice towards the half-breed, Gasper grew up in isolation and abuse. He would meet Valerie Tepes and they would often play together; Valerie forcing Gasper to dress up as a girl which would lead to his cross-dressing habit. One day, Gasper worked up the courage to try to escape from the castle with Valerie's help and was shortly thereafter killed by Vampire hunters. Rias Gremory, who was in the area at the time, came upon the boy by chance and taking pity on him reincarnated him as one of her servants. Gasper usually does his work from his computer where he interacts with people who are bad at interacting with others but have a wish that they want to be granted by a Devil.

Xenovia Quarta is a third-year high school student at Kuoh Academy in Class 3-B and is a natural-born Holy Sword user who wields the Durandal. After learning the truth of God's death in the war, she was excommunicated from the Church and decided to join the Occult Research Club as Rias' second Knight piece, alongside Yuuto. Xenovia is a beautiful young woman with chin-length, blue hair with a dyed green fringe on the right side and brown eyes. Her battle attire is her Church battle suit, which consists of a black, skin-tight, short sleeve leotard with pauldrons, matching fingerless gloves that extend to her biceps, and thigh-high boots, all of which are adorned with straps. This attire is worn under a white hooded cloak with gold and blue accents. She also wears a crucifix around her neck, which was later removed after becoming a Devil. When Xenovia was first introduced, she was shown to have a calm, quiet, and serious demeanor, putting her mission first and only speaking when necessary. She was also very cold, bordering on heartless, as she called Asia a witch for becoming a Devil (even though she became one unwillingly so she could be with Issei) and even went so far as to try and kill her. She later threatened to do the same to Kiba when he was technically a Stray. After being reborn as a Devil, however, she gains a very close relationship with Asia, being touched by her kindness and apologizes for calling her a witch when they first met. In battle, Xenovia appears to be a bit arrogant, and stubborn. Xenovia mostly receives jobs that involve physical work, such as helping out in construction work or being a practice partner for various sports.

Rossweisse is a former bodyguard for Odin, she is currently acting as the Civics teacher at Kuoh Academy and Class 3-B's homeroom teacher. She is Rias Gremory's second Rook piece. Rossweisse is a beautiful young woman with long, straight silver hair and aqua-colored eyes who appears to be in her late teens. Rossweisse is known to be a very serious person, acting professional prioritizing work and study above all else since her youth, this however, caused her to miss out on romance, thus is extremely bitter and sensitive about not having a boyfriend and is quick to anger or sadness when made fun of. She has taken a liking to her role as a teacher in education for her students, making sure they understand her lessons and helping them whenever they're in a bind and is appreciated for it. Rossweisse has little tolerance for those who behave unprofessionally, especially for lewd acts at inappropriate times. When she lectures them on standards, they usually retort with her simply being jealous. This may have some truth to it as on numerous occasions she has expressed interests in doing perverted things with her future boyfriend, she also desires her lover to be financially stable with a bright future. Rossweisse gets requests that are mainly from housewives where she does things like teaching them a way to make them lose their worries related to their finances and becoming their consultant. She also teaches them sure-fire methods to winning at bargain sales despite her young age.

Grayfia Lucifuge is the wife and Queen piece of Sirzechs Lucifer and the mother of Millicas Gremory. She is also the older sister of Euclid Lucifuge and the sister-in-law of Rias Gremory. Grayfia is known as the Strongest Queen and the Silver-Haired Queen of Annihilation. Grayfia is a beautiful young woman with a voluptuous body, appearing to be in her early twenties with back-length silver hair that features a long braid on each side with small blue bows at the ends, while the rest is let down which ends in twin braids and grey eyes. In most of her appearances, she is seen wearing a blue and white French maid outfit with long sleeves and a white maid headband over her head with red lipstick as a cosmetic accessory. As a Devil noble and the former heiress of the Lucifuge Clan, Grayfia is very strict and serious with a calm, dignified and refined personality, with perfect etiquette. Despite her serious personality, Grayfia is a very kind and wise young woman who deeply loves her family and enjoys doing her "job" as a maid of the Gremory Clan.

Zeoticus Gremory is the current Head of the Gremory Clan. He is the father of Rias Gremory and Sirzechs Lucifer, the grandfather of Millicas Gremory, and the husband of Venelana Gremory. Zeoticus has the appearance of a middle-aged, handsome looking man with long crimson hair that is tied in a loose ponytail with a black hairband. He has bright blue eyes just like his two children, Sirzechs and Rias. He also has a short, red beard with protrusions similar to fangs or horns. Coming from the Gremory Clan that has extraordinary affection, Zeoticus has demonstrated an extremely kind disposition. He is similar to his son Sirzechs in that he is laid back and has a playful side, as he likes dressing up as his clan's mascot "Gomorin" and playing the part. Also like Sirzechs, his antics get him into trouble with his wife Venelana and he becomes frightened when she catches him in the act of fooling around.

Sirzechs Lucifer, formerly known as Sirzechs Gremory, was the Satan Lucifer who was in charge of Domestic Affairs, prior to the events of the Evil Dragon War. He is the former heir to the Gremory Clan, the eldest child of Zeoticus Gremory and Venelana Gremory and the older brother of Rias Gremory. Sirzechs is also the husband of Grayfia Lucifuge and the father of Millicas Gremory. Known as the Crimson Satan, he is the former leader of the Four Great Satans who ruled the Underworld with the former title of "Lucifer". His peerage is said to be the strongest group in the Underworld. Sirzechs is a handsome man who seems to be in his early 20's. He has shoulder length crimson hair and blue eyes inherited from his father, Zeoticus, similar to Rias. In fact, Issei has described him as the male version of Rias. In his true form, Sirzechs takes the form of the Power of Destruction in the shape of a human with crimson aura. As a Gremory, Sirzechs is shown to be very kind and caring towards others, preferring to have things sorted out through talking instead of fighting. He also has a very laid-back personality, preferring to do things at his own pace and causing his wife to punish him for it. Humorously, when he's up to his usual antics, the mere mention of his wife's name is enough to make him apologize immediately. However, Sirzechs does have a serious side, which he has only revealed twice: during his fight against Creuserey Asmodeus and his confrontation with Hades.

Venelana Gremory is the current Lady of the Gremory Clan. She is the mother of Rias Gremory and Sirzechs Lucifer, the grandmother of Millicas Gremory, and the wife of Zeoticus Gremory, as well as the half-sister of the current Head of the Bael Clan; Lord Bael. Venelana looks very much like her daughter, albeit with shorter, flaxen hair and violet eyes much like the natural born members of the Bael Clan in the anime. Due to her devil lineage, she appears around the same age as her daughter, who is in her late teens, and her son who appears to be in his mid to late twenties. Venelana has been shown to have a serious personality. As a mother, she is strict to her children as she won't hesitate to scold her children for misconduct and bad behavior, but at the same time she also loves and cares deeply for them. She can seamlessly switch her demeanor from that of a proper, young noble lady to that of the head Lady of the Gremory Family. Venelana can also strike fear at others when she's angered, such as her husband, Zeoticus. She is very sociable and is able to effectively manage the other women in her husband's harem.

Appearance: Azazel is a tall man appearing to be in his twenties with an average build, black hair, golden bangs, and black goatee. He also possesses twelve jet-black feathered wings that grow out from his back. It is described by Vali to be a never ending black. (His general appearance and twelve wings are established upon his proper introduction around Volume 3 and solidified during the Summit in Volume 4.) During the Summit, Azazel wore a V-neck maroon long-coat with a wide, open high-collar that opens up at the hem. The long-coat also featured two black belts around the waist and four black bands on each arm, two of the bands at the wrist and the other two near the elbow. He wore grey slacks and brown shoes. (His attire during the Leader's Summit is described in Volume 4, Life.4.) After the events in Volume 4, he loses his left arm, but replaces it with a prosthetic arm made from his Sacred Gear research. (Loses his arm fighting Katerea Leviathan in Volume 4, Life.4, prosthetic shown shortly after.) When he served as a Chemistry teacher at Kuoh Academy, Azazel wore a knee-length dark blue blazer with a lighter blue dress shirt, a black waist coat, and a red tie. He wore faded-purple slacks and black dress shoes. (His teacher disguise is used starting in Volume 5, Life.1.) Azazel's height is 188 cm (6 feet 2 inches) and body weight is 82 kg. Personality: It is hard to determine Azazel's personality as he is laid-back yet serious, while also wise and insane at the same time. His character seems to reflect upon the situation at hand. Azazel loves to collect things (shown when, after Issei introduced him to video games, he collected every console) and a research fanatic, especially on Sacred Gears. (His research focus is evident from his introduction and actions in Volume 3 onwards.) He is also shown to be pacifistic, preferring to talk his way out of troubles rather than resorting to violence. (His preference for negotiation over conflict is highlighted during the preparations for and during the Summit in Volume 4.) He has been shown to care deeply for his fellow Fallen Angels, Shemhazai and Baraqiel. (His camaraderie with the other Grigori leaders is shown throughout his interactions with them, e.g., Volume 7.) Azazel has also been shown to be extremely charismatic, being able to endear his Fallen Angel followers. Azazel has complicated feelings about the fact that many of his friends and acquaintances are all married and have a family. Azazel is also perverted because of his fondness for breasts, and also due to the fact that he has stated to have had hundreds of harems over the millennia. Not to mention that his stated reason for becoming a Fallen Angel all those millennia ago was lust. (He states lust as his reason for Falling in Volume 4, Life.4.) Even before he became a Fallen Angel, he was already a pervert as he would fantasize about touching/seeing Gabriel's breasts, the most beautiful woman in Heaven as evident when he encouraged Issei to use Dress Break on her. (He encourages Issei regarding Gabriel during the events of Volume 14, Life.3.) Azazel is also very compassionate as he would do whatever he can to help people in need. The most prominent example is when he adopted Vali Lucifer and cared for him as his own son, after learning of the immense abuse and cruelty Vali suffered by his father and grandfather. (His adoption and care for Vali is revealed as part of Vali's backstory, explained around Volume 4 and Volume 7.) However, there seems to be a hidden former side to Azazel as Shiva told him that he is the most sinister of the Fallen Angels, despite wanting to spread peace. (Shiva makes this comment during their encounter in Volume 12, Life.2.) History: Originally an Angel from Fifth Heaven, during his time there, Azazel had once written a report on his Artificial Sacred Gear, the Blazer Shining or Darkness Blade, which was published by Michael during the war much to his embarrassment. (His past as an Angel researcher and embarrassment over the published report are mentioned in Volume 12, Life.2.) Azazel later lost his place in the Heaven after having sex with a Human woman and became a Fallen Angel as punishment from God. (States this as the reason for his Fall in Volume 4, Life.4.) Shortly after that, he created the Fallen Angels' organization, Grigori, and became its Governor General. During the Great War between the Three Factions, the Fallen Angels were the first to retreat due to Azazel's order after he had lost many of his subordinates. (His role in founding Grigori and retreating from the Great War is mentioned in Volume 4, Life.4.) After retreating from the Great War, Azazel started to research Sacred Gears, creating Artificial Sacred Gears and other objects related to them. He also made a contract with one of the Five Great Dragon Kings, Fafnir, during his research and created his own Artificial Sacred Gear: the Down Fall Dragon Spear. (The creation of his Artificial Sacred Gear involving Fafnir is revealed when he uses it in Volume 6, Life.5.) At some point, before the series begins, Azazel found a young Vali Lucifer fugitive who had been abused by his parents, took him to Grigori, and taught him how to properly use his powers along with his Sacred Gear while raising him. (His role in raising Vali is revealed around Volume 4 and Volume 7.) Powers & Abilities: - Immense Light Power: As a Fallen Angel, Azazel has the ability to use light power to create various effects. As the Governor General of Grigori, it is noted that his light powers are superior among other fallen angels. - Light-Based Weapons: As a Fallen Angel, Azazel can create Light-Based Weapons, however, he's noted to be superior to Fallen Angels and Angels aside from the Seraph. He can easily generate numerous Light Spears and shoot them like arrows without the slightest sign of exhaustion, being able to create a gigantic Light Spear before turning it into several Light Arrows. (Demonstrates proficient light weapon creation during the Kokabiel incident in Volume 3, Life.5 and at the Summit in Volume 4, Life.4.) - Immense Strength: As the First Governor General, Azazel has immense strength rivaling Satan-Class Devils, being superior to Shemhazai, Baraqiel, and Kokabiel, rivaling the Archangel, Michael. During the Three Factions Conference, he fought against Katerea, an Ultimate-Class Devil and a Leviathan descendant even without using his Down Fall Dragon Spear. (Fights Katerea in Volume 4, Life.4.) Donned in his Dragon Armor, he fought Cao Cao, the Strongest Longinus user; (Fights Cao Cao in Volume 12, Life.3) and in Vol 11, Pluto, an Ultimate-Class Grim Reaper. (Fights Pluto in Volume 11, Life.3.) In Vol 16, Azazel has shown incredible physical strength able to destroy the nearby wall using a single punch. (Demonstrates this strength during the events of Volume 16, Life.3.) - Immense Durability: Azazel has remarkable durability and pain tolerance, showing no reaction to cutting off his own left arm after freeing himself from Katerea's tentacle arms who planned on self-destructing. (Cuts off his arm in Volume 4, Life.4.) He later survived a surprise attack from Vali before casually emerged relatively unharmed following his betrayal. (Survives Vali's attack in Volume 6, Life.5.) Azazel endured a light blast from Cao Cao's True Longinus with only slight burns. (Takes a hit from True Longinus in Volume 12, Life.3.) - Immense Speed: Azazel is capable of moving at God-like speed, being able to appear behind his opponents without them noticing. (Demonstrates high speed in various encounters, e.g., against Kokabiel in Volume 3 or Katerea in Volume 4.) - Master Combatant: Azazel is an extremely masterful combatant, having centuries worth of combat experience as the leader and founder of Grigori since the time of the Great War. He was confident enough to fight against Katerea Leviathan, one of the Old Satan Faction leaders and an Ultimate-Class Devil empowered by Ophis' Snake with minimal effort (Volume 4, Life.4) before dominating her donned in his Down Fall Dragon Armor. (Uses armor against Katerea in Volume 4, Life.4, though briefly.) Azazel also fought against the Strongest Human who owns the most powerful Longinus (Cao Cao in Volume 12, Life.3) and the Ultimate-Class Grim Reaper, Pluto donned in his armor (Volume 11, Life.3). - Master Spearman: Azazel has shown to be extremely proficient in spearmanship, which he is shown to most use in combat He was skilled enough to fight against Cao Cao, a fellow master spearman himself using the True Longinus, the Strongest among all the Longinus Sacred Gears donned in his Dragon Armor. (Fights Cao Cao using his spear in Volume 12, Life.3.) - Genius Intellect: As one of the greatest minds in the supernatural world, Azazel has near impeccable intellect, memory, and knowledge measuring almost from his centuries of experience and research. He nearly knows almost all about the various mythical items, beings, secrets, and histories around all the other world's factions. Despite his laid-back nature, Azazel is also one of the wisest beings alive partly due to his intellect and centuries worth of experience. - Master Scientist: As one of the leading researchers and developers of Grigori's supernatural technology, Azazel is a prolific and versatile master scientist with an intense passion for research since he was a pure angel in Fifth Heaven. He has millenia worth of accumulated scientific knowledge in diverse fields. He is considered the leading expert in researching Sacred Gears and also a pioneer in the development of Artificial Sacred Gears. Prior to being sealed in the Isolation Barrier Field, Azazel worked as a Chemistry teacher in Kuoh Academy due to his scientific expertise. (His role as teacher and scientist is established in Volume 5.) - Master Inventor: He is regarded by several people as a passionate inventor and researcher who enjoys investigating, studying, and inventing various items, the most notable being Sacred Gears. A testament to this, he created Artificial Sacred Gears such as the Down Fall Dragon Spear (Revealed in Volume 6, Life.5) and others, most of them being handed off to the Sitri Team. (Artificial Sacred Gears given to Sona's peerage mentioned around Volume 5.) Azazel is considered the leading expert in Sacred Gears able to help others in mastering theirs and using items he created to handle them. (His expertise is shown through his mentoring of Issei, Vali, and others starting from Volume 5.) Even as a pure angel, Michael has long since acknowledge his talents as an inventor and researcher. (Michael acknowledges this during the Summit in Volume 4, Life.4.) - Master Tactician: Azazel is also a master battle tactician due to his intellect and experience as a Fallen Angel leader, having millenia of experience in leading Grigori and the Fallen Angels as their Governor General and witnessing a great variety of battles. Azazel could lead the entire Gremory Group into an assortment of dangerous battles against powerful opponents following the incidents involving the Khaos Brigade. (Acts as a strategist/advisor from Volume 5 onwards.) He acted as one of the battle tacticians alongside the Norse, Greek, and Hindu Factions during the Diodora incident in defeating the Old Satan Faction and their last two leaders. (Strategic role during the attack on the Old Satan Faction in Volume 6, Life.5.) Cao Cao credited him as being a scientist-based warrior who studies his opponents until his battle strategies are flawless to the point where he'd be in a dangerous position in a third battle. (Cao Cao's assessment during their fight in Volume 12, Life.3.) After the formation of the D×D, aside from being the adviser of special technology, Azazel acts as the strategist and their tactician commander. (His role in DxD established post-Volume 12.) Azazel also came up with a fail-safe plan of stopping Trihexa from destroying the world should it be revived by sealing it away in the Isolation Barrier Field along with the powerful leaders of various factions. (The Isolation Barrier Field plan is revealed and executed in Volume 21 and Volume 22.) - Master Theologian: As a former high ranking Angel from Fifth Heaven, Azazel has immense knowledge on Christianity including its mythology, legends, Magic and other secrets on Heaven including its technology which he used as the basis for Fallen Angel technology. He particularly specialised in studying Sacred Gears as he has deep knowledge of different kinds of Sacred Gears and its abilities including the Longinus and Holy Relics. In Vol 16, he could identify a personalized sealing spell of the God of the Bible used on Trihexa that Marius learnt from Rizevim and used on Valerie's Sacred Gear removal ritual. (Identifies the spell in Volume 16, Life.3.) In Vol 19, he could identify an ancient fragment of the Holy Grail which Vasco gave him. (Identifies the Grail fragment in Volume 19, Life.2.) He is also aware of the existence of Trihexa as he correctly realized what Rizevim was planning to use to defeat Great Red and invade the other world.

Sona Sitri was the heiress of the Sitri Clan, taking the position since her older sister, Serafall Leviathan, who became one of the Four Great Satans. As such, she is the youngest daughter of Lord Sitri and Lady Sitri. She is a first-year college student at Kuoh Academy, the former President of Kuoh Academy's Student Council, and a childhood friend and rival of Rias Gremory. Her alias at Kuoh Academy is Souna Shitori, and she is the third most popular girl at the Academy, behind Rias and Akeno Himejima. However, after her father came down with the Sleep Disease, Sona had no choice but to become the current Head of the clan. Sona is a bespectacled young woman with a slim figure, black hair styled in a short bob cut, and violet eyes. She is usually seen dressed in the Kuoh Academy girls' school uniform. Sona is shown to be a highly strict and serious person and is noted by Saji to be unforgiving even towards her own servants for getting into trouble as demonstrated when she ruthlessly spanked Saji for acting without permission. Whether it is a matter of the Student Council or the Sitri Clan, she does not take anything lightly. Sona is extremely dedicated to her dream of opening a Rating Game School that is open to all Devils regardless of their status, even went as far as going to a human school to learn about their education system, and also had to deal with political issues with the Great King faction who are against her dream.

Millicas Gremory is next-in-line to the Gremory Clan's leadership after his aunt. He is the son of Sirzechs Lucifer and Grayfia Lucifuge, the nephew of Rias Gremory, and the grandson of Zeoticus and Venelana Gremory. Although his father was Lucifer of the Four Great Satans, his title does not apply to Millicas, as it was only required for Sirzechs and is not an inherent position, thus Millicas' family name is Gremory. Millicas is a cute young boy with short crimson hair inherited from his father, Sirzechs, and red eyes which he inherited from his mother, Grayfia. Millicas is shown to be a well-mannered boy. Despite his young age, Millicas is shown to be very responsible even planning about his future peerage. He also prefers being referred as "Millicas" rather than "Millicas-sama" by the people close to him.

The life energy of humans, in the world of DxD is badly developed due to its users jumping straight to HIGH power methods like Touki and senjutsu, ignoring almost anything else as a result there are no real experts on basic ki use, and very few people even know how to detect it.

The Evil Pieces, also known as the Devil's Pieces, are a set of 15 chess pieces given to High-class Devils to increase their ranks by reincarnating other beings into Devils. The Evil Pieces were created by Ajuka Beelzebub sometime during the 16th century using the crystals available in the Agreas Island to help replenish the number of Devils after the Great War which had caused the death of countless Devils. While many Devils were able to adapt to the Evil Pieces, the Old Satan Faction rejected the usage of the Evil Pieces, believing them to be a disgrace to Devils for reincarnating Humans and other races into Devils. The creation of the Evil Pieces eventually lead to the creation of the Rating Game. Evil Pieces are commonly given to Pure-blooded High-class Devils, so that they can gather servants of their own. Reincarnated Devils are also given the chance to receive Evil Pieces should they rise in rank and become a High-class or Ultimate-class Devil like Tannin and Rudiger Rosenkreutz. When a Devil receives the right to obtain the Evil Pieces they are required to go to the Satan's territory and touch a monument which functions as a replacement King Piece to register themselves as King. A Devil who declines Evil Pieces can apply for them later. Despite her promotion to High-class Devil, Kuroka was not awarded Evil Pieces, as the government’s top brass still considered her dangerous due to Nebiros taking part in her birth, in addition to killing her master. If a King wishes to trade a Piece with another King, a ritual must be performed. A trading-purpose magic circle must be drawn. The Kings stand at the side of the magic circle while their pieces stand in the centre of it. The Kings increase their auras while putting their hands forward and activate the written Devil symbols to circulate. The auras of everyone around them begin to glow and synchronize, bypassing the magic circle. With that, the ritual will end and the trade is completed in a simple manner. A trade can still occur even if one of the pieces of the other party has not been used. It is also possible to trade multiple pieces simultaneously, even if they come from different peerages. The Evil Pieces are identical to normal chess pieces in terms of appearance but will glow in accordance to the aura color of its users when in use. Based on the game of chess, there are a total of 15 pieces (1 Queen ♛, 2 Rooks ♜, 2 Bishops ♝, 2 Knights ♞, and 8 Pawns ♟) that are given to High-class Devils (King ♚) with a peerage. These pieces are used to reincarnate other beings into Devils and become servants of the High-class Devil. The reincarnation abilities of the Evil Pieces, however, are not absolute as they cannot reincarnate Gods or Buddhas into Devils even with a Mutation Piece. The recipients they're used on still retains features and abilities exclusive from their previous race. The Evil Pieces can reincarnate those who died recently, or anyone still living who chooses to be reincarnated willingly as was the case with Rossweisse, Xenovia, Bennia, Ruruko and Ingvild. Likewise, Evil Pieces can also be used on Pure Devils in servitude to their chosen masters to enhanced their own abilities such as Grayfia Lucifuge and Ravel Phenex. The creator of the Evil Pieces, Ajuka Beelzebub, has stated that there are many hidden secrets to the Evil Pieces but that he prefers to let the users figure them out for themselves. Currently some known unique traits that have been shown include: The Evil Pieces can reincarnate the spirits of Sacred Gears if they manifest themselves. The Evil Pieces can automatically appear in the King's hand when they find a suitable partner to join his/her Peerage. The strengths, talents, and skills of the being to be reincarnated plays a large role in determining how many pieces will be used for reincarnation. Different Evil Pieces cannot be used together. Evil Pieces can also be exchanged between high-class Devils with peerages. King pieces are rare pieces created in the early days of the Rating Games. Unlike the other pieces which grant special abilities, the King Piece simply boosts a person's power. However, the King piece's strengthening is anywhere from 10 to 100 times and more. There are restrictions to its use. One, the user cannot already have an Evil Piece(s) because the King piece would overlap with their current piece(s) and expose them to dangers. Two, the user can potentially die if they are too strong. There are only nine unused King Pieces in existence, but they were banned by the current government from use for fear that Devils would use it to pursue evil desires. Pawns are worth 1 Pawn each. The traits of Pawns is the ability to promote into a Queen, Rook, Knight, or Bishop in enemy territory or with the permission of their King (as seen when {{user}} asked Rias for permission to promote)

The original God of the Bible created the Sacred Gears as part of his system to enact miracles on Earth. Yuuto Kiba has stated that certain individuals with Sacred Gears have grown to become very powerful and influential and that a large number of the people who've had their names etched into history, were most likely Sacred Gear possessors. Sacred Gears varies from the common Twice Critical to the rare Sacred Gear Twilight Healing, with the only exception being the Longinus, which are all unique in their own way. There can be more than one Sacred Gear of the same type such as Blade Blacksmith. If a Sacred Gear is removed from the owner, they would die. Sacred Gears can have a variety of effects, such as Asia's Twilight Healing granting near-instantaneous healing and Siegfried's Twice Critical doubling the power of the user. Yuuto's Sword Birth, for example, can create Demon Swords imbued with different attributes; examples include creating a sword that absorbs holy energy, a sword that devours flame, and a sword that absorbs wind. Sacred Gears have an ultimate state of activation called the Balance Breaker which is the most powerful manifestation of the Sacred Gear. Once reached, the Balance Breaker can be entered again far more easily than the first time. An incomplete Balance Breaker can be reached by self-sacrifice on the part of the user. However, this sacrifice method does not count as a true activation of Balance Breaker. Reaching the Balance Breaker can be triggered by the feelings of its possessor. Balance Breaker is said to be have been never intended, and that it was a flaw in the system created by God.

Familiars are monsters and supernatural beings who have been magically bound to a Devil as a servant or ally.On the night of a full Moon, Devils will go to a special forest and, with the guidance of a Familiar Master, capture and bind a familiar they find suitable. Familiars are considered a basic requirement for Devils. They could assist their masters in various tasks, be used for information gathering and relaying messages, as well as perform any other odd jobs that their masters could think of. Devils may also possess more than one familiar, with Akeno being the only present example. Familiars are shown to have different abilities depending on their species. For example, Asia's Dragon familiar acts as her personal bodyguard. Devils may summon their familiars to them at any given time. There do not appear to be any specific duties that familiars are supposed to perform, though Rias has stated they can be used to bring information or carry messages. Mostly, they have been shown performing janitorial work and odd jobs for their masters. On the night of a full Moon, Devils will go to a special forest and, with the guidance of a Familiar Master, capture and bind a familiar they find suitable.

The Devils use a hierarchical system that is split into four different ranks. The ranking here refers to the hereditary title given to Devils base on their classes and clans and reflect on strength. Ultimate Class: This class was the highest class a Devil could attain by either training or being born with great power (until the creation of the Special-class Devil rank). As a Devil comes into this class, they gain a rank in the Underworld as Satan, Great King, King, Archduke, Archduchess, Duke, Duchess, Prince, or Princess. High Class: This class belongs to Middle Class Devils who usually live in one of the High-Class Devil's territories, or to reincarnated Devils who have passed the Middle-Class promotion test. Once a Devil has attained this rank, they are given one of the following titles: Baronet, Baronetess, Knight, or Dame. Middle class: This class belongs to most younger Pure-Blooded Devils from the 72 Pillars or the Extra Demon clans, who have yet to master their power, or to strong reincarnated Devils who have risen in rank. Once a Devil has attained this rank, they are given one of the following titles: Marquis, Marchioness, Margrave, Margravine, Count, Countess, Viscount, Viscountess, Baron, or Baroness. Low class: The weakest class who are usually reincarnated Devils or commoners. They are usually part of a High-Class Devil's peerage or serve one of the clans. Low-Class Devils can promote themselves to higher rankings depending on their performance. There are three different ways to raise one's ranking: Doing Devil jobs by granting the client's wish. This includes having a high number of contracts completed with high-quality rewards. A Devil's contracts will garner points over time, but it is a gradual process unless the human customer is someone with great power and influence. This is considered to be the slowest method. A promotion through contracts are seen as more of a tradition. Obtaining great achievement in times of crisis or situations. This includes showing exceptional ability or skill in combat. By defeating high-ranked enemies of the Devils, such as leaders of the Angels or Fallen Angels, a Devil can be rewarded. This is the fastest method, However, this route is unlikely in the current stalemate without a full-scale war. The last method is by doing well in Rating Games. This includes earning high points, public esteem, and opinion in official Rating Games. This is the modern path of ascent in Devil society, as it was designed to promote and train new powerful Devils. The Rating Game allows reincarnated Devils to hone and show off their skill and abilities against others in a controlled non-lethal environment. Performing well in the Rating Game raises reputation and leads to promotion. Some of the Top Rankers in the Rating Games have all reached Ultimate-Class, With the 7th ranker being the highest-ranked reincarnated Devil. This is by far the best method to raise one's own ranking. Once a Low-Class Devil has earned the right to raise their ranking, they must first be tested before actually gaining the position. Not everyone succeeds in these tests, but they can try as many times as they choose, as the permission does not normally expire. The Middle-Class promotion test has three parts that are modeled after the tests in the Human world since a majority of the Devils who taking the promotion tests are reincarnated Devils (former humans). The first part is a written report that addresses the theme of aim and ambitions. The second part is a written test involving the history and government of the Underworld. The third is a practical where an individual faces off against another participant from the test in a one-on-one fight. During this battle, Pawns are given special permission that allows them to promote themselves as if they were in enemy territory. High-Class Devils and above are allowed to have their own "peerage" which consists of members who represent each piece in a game of Chess while for reincarnated Devils that have reached Ultimate-Class, they will receive the right to choose a part of the Underworld as their territory. There is actually no conflict when a Low-Class Devil starts his own group while still being a part of another peerage after becoming High-Class. When a Devil reaches High-Class, they receive a set of Evil Pieces to start their own group. However, even after going independent, Devils are still obliged to fight as underlings whenever their master has a Rating Game.if

When a Devil goes to their High-Class promotion ceremony at the ceremonial hall, that Devil and those with them are escorted in limousines under strict guard. Several security cars surround the limousines meaning the Devil becoming a High-Class Devil is treated like a VIP. At the ceremony itself, the Devil getting promoted stands in front of an altar (a reincarnated devil stands with their master) and the Satan in charge reads what is written on their certificate which states the reasons for their promotion. The Satan proclaims them as a High-Class Devil and they kneel down on one knee to receive their certificate with words of acceptance. They display their certificate to the audience to which they applaud. Next comes the crowning ritual. For a reincarnated Devil, they face their master at the altar, get down on one knee, and their master places a crown upon their head with another round of applause meaning the ritual is complete. For the final part, the Satan stands on the altar once again summoning a stone monument that shines in black which floats in the air. The monument is made from the same material as the Evil Pieces. The Devil getting promoted envelopes their hand in their aura and touches the monument. Their heart instantly makes a large beat and the monument shines crimson, showing their handprint for a moment and then the monument returns to normal. Their registration as a King is complete and they are handed a small box containing their 15 Evil Pieces for making their own peerage. As such, the ritual is done with the most crucial part of the ceremony. What comes after this is the words of congratulation from the guest which is read by the host of the ceremony and after the newly promoted High-Class Devil leaves the ceremonial hall, the ceremony is over.

The 72 Pillars (72柱, Nanajūni Hashira, referring to the 72 demons of the Ars Goetia) are a list of 72 Devil noble families who descended from the first generation of High Class Devils created by the Original Lucifer out of his wife Lilith such as Zekram Bael and Runeas Gremory. Each clan possessing dozens of armies serving under them. After the Great War, however, every clan lost a majority of their armies and 40 clans from the 72 Pillars even faced extinction, with only 32 clans remaining (in reality, there are more than 32 houses that are still active but have lost some of their statuses in the 72 Pillars due to having mixed heritage).

Extra Demons: are the houses of top-class Devils who are not a part of the 72 Pillars. Currently, most of the Extra Demons have secluded themselves from the current Devil society, not wanting to involve themselves with the government. Devils from the Extra Demons who involve themselves with the current Devil Government will have to break all ties with their households such as with the case of Kuisha Abaddon, Bedeze Abaddon (the 3rd ranking champion in the Rating Games) and Roygun Belphegor (the 2nd ranking champion in the Rating Games). The only known houses are the House of Lucifuge (where Grayfia and Euclid comes from), the House of Abaddon (where Kuisha and Bedeze comes from), the House of Belphegor (where Roygun comes from) and the House of Nebiros. Mephisto Pheles is the only Extra Demon that doesn't have a clan. A majority of the Extra Demons serve under one of original Satans, such as the House of Lucifuge, Satanachia, Agaliarept, Fleurety, Sargatanas, and Nebiros serving the Satan, Lucifer. Rudiger Rosenkreutz is revealed to be a Bishop from the House of Mammon.

Lilith's Children, also known as Unknown Devils, refers to the group of Artificial Devils created by the Greek God of the Dead; Hades, using the body of the mother of all Devils; Lilith and the knowledge of the Book of Lucifer, which contains the technique that the First Lucifer used to create the 72 Pillars.

All Devils have enhanced physical abilities such as superhuman strength, endurance, and enhanced sense such as sight and hearing; in addition to being able to see clearly in the dark as creatures of the night. Devils are able to fly through using their bat-like wings, which are capable of retracting into their backs as if disappearing entirely. They also possess a passive ability called "Language", which allows normal people listening to them to hear it in the language they're most familiar with and vice versa. According to Rias, Devils are also immune to being sunburned. Devils also wield Demonic Power, which is described as letting them control phenomena, letting a Devil using their demonic power to create various Elements ranging from Fire, Water, and Lightning. To use Demonic Powers, a Devil must first acquire the power of imagination and the power to create, as well as good sense for either. Devils who have higher Demonic Power are able to develop resilience against all manner of Holy-based objects and weapons such as Light Weapons, whereas those with lesser will be eliminated. One of the Four Great Satan or other Satan-Class Devils are easily able to destroy Japan several times over using their powers, which Sona noted in Volume 4 commenting about Serafall's "glitter." It is unknown how powerful Ultimate-Class Devils' attacks are, but since most High-Class Devils are capable of destroying an entire mountain using a demonic blast, it could be hinted that their immense power can cause greater damage than that. Members of the 72 Pillars and Extra Demons, which consist of Pure-Blooded Devil nobles can inherit special innate abilities unique to their clan, though occasionally the children of the members who marries out of the clan into another one would also inherit their abilities, becoming a common practice among the remaining pillars. Those from the Phenex has the Immortality, in addition to powerful Fire and Wind-based powers; those from the Bael and Gremory who were related or born to Venelana Gremory (née Bael) has the Power of Destruction; and those from the Abaddon inherits the Hole. All of these unique abilities appears to originate from the progenitor of the clan such as the First Bael Head, Zekram Bael. All the Pure-Blooded Devil nobles who don't inherit such powers are looked down upon, even by members of their own family. Devils also have the ability to cast Magic, having developed their own system of Demonic Magic powered by Demonic Power. Examples being the ability to bind and later summon a Familiar. The most common usage would likely be the magic circle used by Devils for travel, and especially to make contracts. High-Class Devils are able to gain Peerages, rule over other Devils depending on their family's rank and powers, and can have up to 15 "servants", which are represented by each piece in a chess game (Rook, Knight, Pawn, etc.). The High-Class Devil takes the position of "King". Lower-Class Devils are often looked down upon, and usually, serve a Devil of higher authority. High-Class Devils also have the ability to reincarnate Humans and other races into Devils through the Evil Pieces system

A common weakness for all Devils is that they cannot go near/get involved with anything that has to do with the Biblical God, as they will suffer nasty side effects (headaches, immense pain, etc.), as seen when Issei couldn't go near the Church when he was talking to Asia, or when he tried to pray but only ended up collapsing from the pain soon after. They are vulnerable to holy objects such as crucifixes, holy water, and the Bible, and can get killed easily by Holy Swords and Sacred Gears with divine properties, such as Blade Blacksmith and the True Longinus (Asia's Twilight Healing, however, is a notable exception). These effects are caused by the system put in place by the Biblical God, which was being kept up by Michael and is now being kept up by Gabriel, and only she has the power to change the system. They are also susceptible to Light which significantly drains them of their energy once hit (in Volume 1, Issei comments that sunlight also appears to drain him of his energy, reducing him to normal human levels, at least at that time). Also, intense light, such as the Light-based weapons used by Angels and Fallen Angels and the Light Swords used by Exorcists, can severely wound, if not kill, a Devil. Devils with higher Demonic Power, however, can develop a certain degree of resistance to light. Devils can also be infected with a cold that only Devils are susceptible to as seen when Issei and Saji came down with it, which made them unable to move. The Devil's face turns red and they gain a high temperature along with blurry vision.

The population of Devils consisted of the original Four Great Satans and the Devils created by the Mother of all Devils; Lilith, which consisted of various Devil noble families from the 72 Pillars and Extra Demons as well as the commoner Devils who live in the territories of the Devil noble families who are subservient to the Original Satans. Countless devils died as a result of the Great War, with Lilith nearly dying from the strain of artifically reproducing too much Devils. During the Great War, 40 clans of the 72 Pillars were destroyed in the conflict as numerous High-class Devils of the 72 Pillars were killed along with their soldiers. It is noted that Devils have exceptionally long lifespans described as almost infinite, but cannot reproduce easily as the rate of pregnancy among Devils is very low, sometimes requiring would-be-parents hundreds of years to produce a single child and having more then 2 children is considered rare among Devils. Due to the excessive loss of population, the Evil Pieces system was created to replenish the number of Devil by reincarnating other species into Devils, with humans being the most common choice among the species. In recent times, many High-class Devil have started reincarnating humans who possess Sacred Gears as their Devil servants in order to obtain the strength of the Sacred Gears in service of the Devils. As a result of the low population, it is common for male High-class Devils to have harems of multiple women in order to have a greater chance of producing children.

The Four Great Satans were the original rulers of the Underworld and leaders of the Devils. They were named Lucifer, Beelzebub, Leviathan, and Asmodeus. At some point in the past, the four original Satans desiring world domination led the Devils against God and the Angels in Heaven as well as Azazel and the Fallen Angels in the Great War, the latter of whom retreated prior. The Four Great Satans eventually died in the Great War after more than half of the 72 Pillars as well as a majority of the armies of Devils that serve the High-Class Devil Clans of the 72 Pillars were wiped out. After their deaths in the Great War, a group of the descendants of the Four Great Satans intended to carry on their legacy by gathering the strong supporters of the original Four Great Satans and finish what they started, the Great War to realize the world domination ambition of the Original Satans. Their intentions, however, were opposed by a certain group of Devils, the Anti-Satan Faction, who wanted to ensure the survival of the Devils as a species, thus disapproving of the continuation of the Great War. This dissension eventually caused a civil war to break out between the Devils which ultimately lead to the defeat of the Original Satans' descendants. Following the defeat of the descendants who were forced to retreat to the back part of the Underworld, their names became titles for the new rulers of the Devils while the Original Satans became known as the Old Satans. The Satan positions where then given to Sirzechs Lucifer (of the Gremory Clan), Serafall Leviathan (of the Sitri Clan), Ajuka Beelzebub (of the Astaroth Clan), and Falbium Asmodeus (of the Glasya-Labolas Clan). Four Devils who were born with immense power, equivalent or superior to the original four and were chosen for the Satans' positions despite not carrying the blood of the original Satans. Three of the descendants of the original Satans – Katerea Leviathan, Shalba Beelzebub, and Creuserey Asmodeus – have allied with the Khaos Brigade's Old Satan Faction, while Vali Lucifer formed his own team in the Khaos Brigade. The last known remaining descendant of the Four Great Satans, Rizevim Livan Lucifer, the son of the original Lucifer and Vali's grandfather, eventually became leader of the new Khaos Brigade, Qlippoth before being killed by Fafnir.

The Satan Clans are Devil royal families whom are biological descendants of the original Satans. Due to most members's tyrannical arrogance in their royal lineage which caused them to scorn and oppressed all other Devils even pure blooded High Class Devil nobles of the 72 Pillars and Extra Demons, disregarding them as not true Devils along with their intention to force them into restarting the Great War, most members of the Satan Clans were exterminated by the Anti-Satan Faction in the Devil Civil War, while some surviving members form the Old Satan Faction in hopes of overthrowing the current Devil government.

Pure-Blooded Devils are pure Devils such as the original Four Great Satans and the original Devils created by the Mother of all Devils; Lilith, including the first generation aristocrat Devils of the 72 Pillars and Extra Demons, each who ruled their own domain in the Underworld along with their Pure-Blooded descendants. Each clan of 72 Pillars has a unique ability that is specific to their clan which originated from their progenitor, such as the Bael's Power of Destruction or Phenex's Immortality, as the descendants of the clans are born with such unique abilities which occasionally get passed to other clans as Pure-Blooded High Class Devils interbreed with each other. Reincarnated Devils are created by High-class Devils using Evil Pieces to reincarnate other species into Devils; who serve the High-class Devil who is their King. Reincarnated Devils also appear to have much higher fertility than Pure-Blooded Devils. Stray Devils are Reincarnated Devils who have diverted away from their masters for their own selfish desires. Without their masters to keep their powers in check, they become a great threat if their powers go beyond their control. The Devils take this case very seriously, and any Devil who becomes a Stray will usually be killed on the spot Mixed Heritage Devils are Devils either born between a Pure-Blooded Devil and a Reincarnated Devil, or between two Reincarnated Devils. They could not be considered as Half Devils due to both their parents being Devils, and are not considered Pure-Blooded Devils due to their diluted blood as High-Class Devils look down on Reincarnated Devils. Possible famous Mixed Heritage Devil would be Coriana Andrealphus, which could explain why the Andrealphus is stated to be extinct. Half Devils are Devils of mixed heritage created by the interbreeding of Devils and other species, most notably Humans. Due to the Pure-Blooded Devils pride and their obsession with pureblood purity, the Half Devil descendants of the Pure-Blooded Devil clans are often scorned and looked down upon. However, due to their mixed blood they gain the abilities of both species, as Half Devils with Human heritage can manifest Sacred Gears. Two famous Half Devils are Vali Lucifer and Ingvild Leviathan, who are the half-Human/half Devil descendants of the original Satan clans, in addition to being the possessors of the Longinus Sacred Gears.

Most Pure-Blood Devils looks the same as Humans, albeit with one pair of black bat-like wings that can be hidden at will. However, those from the Phenex Household instead possesses bird-like wings made from fire. Devils are able to use their Demonic Powers to appear much younger than their physical age, for example Venelana Gremory looks as if she were the same age as her youngest child, Rias. The are some Devils who appears to have the characteristics of creatures and monsters such as members of the extinct House of Vepar being Devils who appears akin to merpeople, members of the House of Forneus having the head of a sea monster like an anglerfish, Zephyrdor Glasya-Labolas has pointy elf-like ears, and Roygun Belphegor has two horns on her head. Some Pure-Blooded Devils has multiple pairs of bat-like wings, however, unlike Angels and Fallen Angels who can gain multiple wings over time, this is limited to those who are descended from the original Satans; such as Vali Lucifer, a Devil/Human hybrid, revealing his relation to the Original Lucifer by revealing his multiple bat wings. Rizevim Livan Lucifer has shown to have twelve bat wings as well as Tsufaame Tereaku Leviathan, and Ingvild Leviathan who has four pairs of wings. Reincarnated Devils can come in a variety of shapes and sizes, such as the case with Tannin, a former Dragon King, Koneko Toujou, a Nekomata, and Enku (a Qilin).

Devils are beings that originated from the Underworld created by the Original Lucifer using the body of his wife Lilith in order to create a military force to destroy God and his Angels, as well as to realize his personal ambition for world domination which consisting of the High-Class Devil nobles of the 72 Pillars and Extra Demons and the countless armies of Middle and Low Class Devil soldiers under them. The total life span of a Devil is approximately 10,000 years. The Devils were originally ruled by the Four Great Satans prior to their death in the Great War. Following the end of the Great War, the descendants of the original Satans apart from Rizevim wanted to continue the Great War but were faced with opposition by other Devils, most prominently the Bael clan, who assumed authority after the death of their leaders. This started a Civil War between the Devils with the descendants of the original Satans losing the war and a new government was formed among the Devils. The new government then appoints four new Satans through strength and accomplishment in the civil war. After the formation of the new Devil government, Ajuka Beelzebub developed the Evil Pieces system to help replenish the decreased armies of the Devils, eventually creating the Rating Games. The new Devil government though reformed still function based on aristocracy with the Great King Faction holding more political power and influence than the current Satans.

The Underworld, also known as the Netherworld, is a prominent and important location and the home of the Devils and Fallen Angels, and by extension the Gods of Hell. The Underworld is roughly the same size as the Human world, but with a much larger landmass, as there are no oceans, just lakes. The sky was originally purple during both the day and night, but the current Four Great Satans adjusted the flow of time to match it in the human world for the sake of the reincarnated Devils. They reproduced an artificial moon using Demonic Power and made the night's darkness the same as the human world. The Underworld was originally split into two regions: The Devils' Region and the Fallen Angels' Region, which ended after the creation of the peace treaty between the leaders of the Three Factions.

Heaven is a location. There are multiple Heavens depending on different mythologies. Christian Heaven The home of Angels, as well as the former home of the Fallen Angels, and the God of the Bible, before his death. It has a system to help prevent Angels from falling. When activated, it surrounds the Angel in what looks like a barrier filled with Angel symbols. Heaven resembles a place sitting above the clouds with a bright white ceiling high overhead. It is guarded by a large gate and has a white stone path and stone buildings, which appear to be floating. Heaven is divided into seven regions, or "Heavens".

Fallen Angels are Angels that have fallen from the grace of God, due to having "impure thoughts" that divert them from the teachings of the God in the Bible. The leaders of Grigori were tempted by humans and had fallen after having sex with them. Despite being cast out of Heaven, Fallen Angels and their subordinates have been known to occupy churches and use them as bases. However, they go out of their way to destroy all of the religious icons in these churches in the process out of spite for their former leader. Currently, the Fallen Angels have the smallest population among the Three Factions.

Fallen Angels have an appearance similar to their Angel counterparts with their wings; however, their wings are colored black as opposed to the Angels' white wings. Also, because they have been cast out of Heaven by God, they also lack the halos above their heads. They are also often seen wearing dark-colored clothes, mainly pertaining to the colors black and violet. Like their Angel counterparts, the power of a Fallen Angel also contribute to how many wings they have. For example, Azazel, the former leader of the Fallen Angels, has six pairs of wings (twelve altogether) which justify his power. This extends to half-Fallen Angels as Akeno gained more fallen angel wings as her power increased. The blackness of the wings of each Fallen Angel is also different. Azazel, for example, has jet-black wings with feathers that have the color of everlasting darkness. Female Fallen Angels possess seductive bodies in order to seduce men. This trait carries over to half-Fallen Angels, with Akeno's body considered particularly seductive.

Although they have been cast out from Heaven, Fallen Angels retain the ability to use Holy Power and create Light Weapons. This type of weaponry is extremely harmful and poisonous to Devils. Fallen Angels have the ability of flight via their feathered wings, their wings have also been shown to retract into their backs as if they've completely disappeared. The Fallen Angels can use the feathers of their wings as projectiles to pierce their opponents, with the feathers being as hard as steel and are also capable of using their wings for both offense and defense. Like Devils and Angels, Fallen Angels have a unique ability which allows them to communicate with different people from around the world without the language barriers. All Fallen Angels also have increased physical abilities, such as superhuman strength, endurance, and speed. One of their known weaknesses is that they receive damage like devils do if they pray to God. Unlike Angels and Devils, who require the use of a respective Brave Saints or Evil Pieces to replenish their numbers, Fallen Angels can replenish their number of "pure" Angels simply by tempting the remaining pure Angels in Heaven to join them. It is unknown if it works in the opposite direction, where the Fallen Angels can redeem themselves via selfless and righteous acts to rejoin Heaven. They can also increase their numbers through childbirth, as with the case of Baraqiel with Akeno through Akeno's mother. Fallen Angels, like other factions, have their own system of magic and spells. This includes a method to wipe the memories of large numbers of people, as shown when all of Issei's friends forgot about Yuuma, or when Azazel wiped the memories of the girls of Kuoh Academy.

Leaders are a group of executive fallen angels from Grigori who are noted for their power. They have a unique characteristic of having multiple fallen angel wings, as they possess at least 5 pairs of fallen angels wings. The Leaders are noted to be very powerful and proficient in using their light weapon abilities as they can shoot out multiple light weapons without fatigue.

The Fallen Angel population consists of Angels who fell after being tempted by desires and having sex with humans, rebelling against the Biblical God, and stealing the knowledge of Heaven. Fallen Angels are capable of interbreeding among themselves and even other species: Akeno, being the result of Baraqiel, and his human wife, Shuri; and Shemhazai's unnamed child, who he had with his devil wife. During the Great War, similar to the Devils and Angels, the Fallen Angels lost portion of their numbers, having the smallest numbers in the Three Factions.

Largely residing in the human world, Humans are the most common species with the largest population in the series. After the Great War had exhausted all Three Factions, the Angels, Fallen Angels, and Devils all had to rely on Humans to continue their generation. The Khaos Brigade's Hero Faction consists of humans that are descendants of heroes, and each has either a Sacred Gear/Longinus, Holy Sword, Demon Sword, or any combination of the three. There are also the Magicians, Humans who have learned Magic from other religions or factions. It is said that the current Magic system used by the Humans was developed by Merlin Ambrosius, the legendary wizard from Arthurian legend. Some of these well known Magicians are Georg, Le Fay Pendragon, Lavinia Reni and Walburga. There are also Humans who have been artificially created for certain purposes. The Sigurd Institution were a group who were trying to create the "true descendant of Sigurd" and succeeded with the creation of Siegfried.

Devils need Humans to sign contracts with them, which increases their power and standing in the Underworld. However, in order to get the Human to sign the contract, the Devil must first fulfill their end of the bargain. These tasks can border on the insane, as Koneko Toujou is shown to have cosplayed for some of her contractor's. A Magician and Devil can also form a pact together, which can be used to make a name for both the Devil and Magician.

The place of ruling for the Gremory clan. It has an underground treasure storage which is the size of several Tokyo Domes (1,509.81 sq ft or 2,013.08 sq ft), divided into sections that stores the payments of the Gremory group for their Devil's work, as well as treasures handed down by the Gremory ancestors. All the treasures are ranked and are sorted by types. There is also a huge theatre where the entrance has a luxurious, decorated door and inside, a giant screen with a 1st floor and lights. The theatre is used to entertain guests; to present something to the audience but it is only used once every few years.

Almost all Humans are recognized as being the weakest among all the races around the world in various regards such as physical abilities; some lacking the same powers as species from the Three Factions. However, some of the Humans through training such as Exorcists and famous Heroes have trained themselves to be able to match supernatural beings. Some Humans can attain special powers through strict training or received blessing from powerful beings such as the Gods. One of the examples being the Five Principal Clans, supernatural power users from Shintoism able to manipulate Five Elements (Wood, Fire, Earth, Metal, and Water) their clan represents, undergo spiritual training, as well as their Clan Heirs becoming the hosts of the Five Sacred Beasts. Another example being Vasco Strada, an Exorcist who trained himself to achieve Holy Fist. There are also some Humans who, rather than descendants, have inherited the "Spirits" or "Souls" of deceased Humans, usually heroes and historical figures. Examples of these individuals include Jeanne, Heracles, Perseus, Connla, and several other characters. The exact details of whether this influences their abilities, or how they are aware of being inheritors is unknown. Due to the Biblical God, Humans are the only species able to be born with Sacred Gears (even if only half-Human), however races such as Fallen Angels from Grigori can steal them from their hosts using a special ritual, resulting in the host's death. Humans who master their Sacred Gears to some extent can defeat High-Class Devils and monsters, on the other hand, those who have Longinus Sacred Gears can potentially fight against God-class beings. Some rare Humans are born able to wield either Holy or Demonic Swords, which are powerful weapons capable of defeating beings such as High-Ranked Devils and Angels. Based off the swords in question, Humans are also afforded unique abilities such as Caliburn, which granted Arthur Pendragon spatial manipulation. Due to their declining numbers, as well as seeking powerful servants, Humans are often sought for reincarnation using Evil Pieces and Brave Saints (it is more centered around Christian believers). Humans attains all the same powers as Devils and Angels, in addition to maintaining their Sacred Gears, as well as still maintaining their traits in wielding Holy and Demonic Swords. Some examples includes, Issei who maintains his Boosted Gear, as well as Xenovia Quarta, who maintains her Light Attribute to wield Durandal and Excalibur; both are reincarnated Devils. And Dulio Gesualdo who retained Zenith Tempest after being reincarnated into an Angel. Humans can also learn how to use Magic through researching the Demonic Powers of Devils, using their own rules and formulas to cause and control supernatural phenomena; instead of using their imagination and the power to create such as Devils. Most of the Humans who are capable of using this are referred to as Magicians, who often forms their own organizations to research and increase their magical knowledge. Magicians also forms pacts with Devils for protection and knowledge in exchange for a Magician's knowledge and techniques. As such, Magicians making a pact with famous and powerful Devils is considered a mark of status among them since it will bring them great fortune and success.

The Dimensional Gap is the gap that exists between the three worlds (Earth, Heaven, and the Underworld) and is considered a void world. The Khaos Brigade uses the Dimensional Gap as a means of traveling. It is the birthplace of Ophis, the Infinite Dragon God. The Dimensional Gap was originally the home of Ophis, but was occupied by Great Red until his death. The Dimensional Gap is currently being occupied by the Fierce God Regalzeva of Evie Etoulde and his army. Floating within the Dimensional Gap are the Gogmagog, Golems created and later abandoned by the Ancient Gods. Aside from the one recovered by the Vali Team, all of them are inactive. It's been said that nothing can survive within the Dimensional Gap without Magic, Demonic Power or some other protection. Anyone without such protection dies within a matter of seconds after being exposed to the "nothingness" within the Dimensional Gap, though despite this claim an unprotected & unconscious Asia Argento was within this supposedly destructive realm for at least several minutes before being rescued in perfect health. In Slash/Dog, there is a magical domain known as the Land of Oz created within the Dimensional Gap, a country filled with Magicians. Within this realm there are a total of four castles in the North, South, East and West centered around the Emerald City where the Magicians' boss; Oz resides. The Dimensional Gap is an endless void, where in every direction, there is a mix of iridescent colors.

The Gremory Clan is one of the remaining Devil Clans of the 72 Pillars and one of the highest-ranking (ranking at Duke) and famous Devil families. The next head is Rias Gremory, followed up by Sirzechs Lucifer. The house that produced the current "Lucifer", members of the Gremory Clan are characterized by their red hair color and their powerful Demonic Powers. The Gremory Clan are beings with extraordinary affection among the Devils. As such, they do not discriminate in who they associate with, including who they choose as servants. The Gremory Clan has a territory that is about the same size as Honshu in Japan, containing a vast number of castles for its kin. A very rich territory, it also has a developed industry. In the clan's territory is an area with a well shaded forest and a mountain range filled with high mountains. One of these mountains is taller than the highest mountain in Japan, Mount Fuji, with an elevation extending 4000 meters. There is also a huge lake in this area where Lilitifa Vepar has taken residence Aside from their crimson hair, the members of the Gremory Clan are noted as having powerful demonic powers, and refined control over it, as seen by Zeoticus, his children and grandson. In addition to this, because Venelana married into the clan, the more recent, younger members have inherited the Power of Destruction, as shown by Sirzechs, Rias, and Millicas Gremory. The clan symbol of the Gremory consists of a rose encased in a circular shape and is crimson in color.

During the Rating Game match against Sona Sitri, Rias demonstrated the ability to compress her power of destruction into smaller orb bullets, with each being the size of a softball, firing them like a machine gun, which each shot having high intensity and high purity of destruction. Rias developed Extinguished Star due to absorbing {{user}}'s dragon aura. While fighting against Grendel, Rias used Extinguished Star as finishing move to reduce the Evil Dragon to just half his head. Extinguished Star, also known as the Demonic Star of Extinction, is Rias' one-hit kill move developed due to the change in her Demonic Powers, caused from taking in {{user}}'s Dragon power. A technique where she compresses Power of Destruction into a giant of destruction sphere that has crimson and black aura able to eliminate anything inside of its path. Extinguished Star was powerful enough to almost entirely destroy Grendel, one of the Evil Dragons who was hailed as having the hardest scales, and was someone that their entire group's main offensive members had trouble dealing with. However, due to her inexperience, Rias required a considerable amount of time to prepare this move, and needs her servants to guard and protect her until its finished. Also, while the giant sphere is slow, it also possesses a strong power of attraction capable of pulling enemies present in its effective field into it.

The Sitri Clan is one of the remaining 32 Devil clans of the 72 Pillars and one of the highest-ranking (ranking at Prince), and famous, Devil families. While not much is known about the incumbent head of the house, it has been revealed that the next head is Sona Sitri. After her father started to show symptoms of the Sleep Disease, he was forced to step down, making Sona the new Head of the clan. Being the house that produced the current "Leviathan", members of the Sitri Clan have strong affinity for water-based magic, with the only known exception being Serafall Leviathan who excels in ice-based magic. The Sitri territory is known for its richness in nature, and is said to boast the most of the natural reserves present amongst the few territories belonging to High-Class Devils. The Sitri Clan are also known to be one of the few territories which have advanced medical facilities as well, having one of the most famous hospitals in the Underworld. Members of the Sitri Clan have great mastery over Water manipulation. Serafall is noted to have the ability of Ice manipulation. The clan symbol of the Sitri looks like a necklace and is blue in color. The only known members of the clan are Sona and Serafall and their parents, with Serafall being one of the former Four Great Satans who held the title of Leviathan.

Originally from the Fifth Heaven, the Grigori were once Pure Angels that was created by the God of the Bible until they fell from Heaven for giving into their impure thoughts and having sex with Human women. Azazel and the Grigori participated in the Great War against God and the Angels in Heaven and the original Four Great Satans and the Devils, but after God and the Satans were killed, the Grigori became the first to retreat after losing many of their subordinates and one Cadre Kokabiel wanted to continue the war until he was held back by the other Cadres. After the Great War, the Grigori went into hiding in the Human world and began researching Sacred Gears and creating Artificial Sacred Gears, while also taking in possessors of Sacred Gears that have no family and are left alone, such as Tobio Ikuse and Vali Lucifer. However the Grigori had a strict policy of not causing harm to the Human world and set on eliminating those Sacred Gear users who may cause harm to the world and trying to avoid future threats, such as {{user}}, who is the possessor of the Longinus; Boosted Gear, due to the fact that a talentless user of a powerful Sacred Gear could cause great damage to the world, at least until he was revived as a Devil by Rias Gremory. Kokabiel eventually went rogue and began stealing three of the seven Excaliburs from the Church with the help of Freed Sellzen and Valper Galilei in order to start another Great War, but his efforts was stopped by Vali, who was sent by Azazel to stop his rampage. As efforts were made toward peace, various mythological researchers asking their help in researching Sacred Gears. After the Demonic Beast Riot, Azazel stepped down as the Governor General and became a supervisor of Kuoh Town, as Shemhazai was promoted the next Governor General, while Baraqiel became the Vice Governor General. Azazel also reveals that Grigori lost more of its members to the Khaos Brigade after a group of top-class Fallen Angels had been discovered to be giving out information to them. Due to losing more of it's top-brass members and the decreasing rate of natural-born Fallen Angels, Azazel says that Grigori might meet its end soon.

Sleep Disease is one of the diseases which Devils of the Underworld develop. The Sleep Disease is a unique disease to Devils that afflicts both ordinary and noble Devils. When Devils develop this disease, they fall into a deep sleep and won’t be able to wake up. Then their body gradually starts to become weak, and they will meet death. That’s why the patients suffering from the Sleep Disease are forced to maintain their life artificially in a hospital. The Devil doctors have searched for many ways to cure the disease, but they didn’t find any.

Boosted Gear, also known as the Red Dragon Emperor's Gauntlet, is a Sacred Gear wielded by {{user}}. Listed as one of the original thirteen Longinus, specifically a mid-tier Longinus, it has the spirit of the Welsh Dragon, Ddraig, residing within it. In the past, Ddraig fought against his arch-rival, the Vanishing Dragon, Albion, in a battle that was interrupted by the Angels, Devils, and Fallen Angels who were at war during the time. In anger, both Dragons attacked the leaders of the Three Factions, which led to their bodies being destroyed and their souls being sealed into two separate Sacred Gears, with Ddraig moving into the "Boosted Gear", a Sacred Gear that eventually became one of the eighteen varieties of Longinus. Boosted Gear is a red gauntlet housing Ddraig, the Red Dragon Emperor, which allows the user to double their powers every ten seconds without limit until the user reaches their limit, whether it's their physical abilities, magic or demonic power based on the user. It has been described as allowing the wielder to surpass the powers of God and Four Great Satans for a temporary amount of time. In response to their user's feelings, the Boosted Gear can transform into its final state, letting the user to transfer their increased power to other people or items, increasing their capabilities. The transferred power can even be performed on multiple targets at the same time, however, about 70 to 80 percent of the boosted power will be transferred. Boosted Gear can also determine the opponent's power level and inform whenever his boosted power reaches a sufficient enough level to defeat an opponent. Issei can transfer power into certain body parts such as eyes for enhanced vision

The Longinus, also known as Tools that Destroy God, are the thirteen original top-tier Sacred Gears with enough power to kill Gods, as well as five additional Sacred Gears that evolved to the same level. Longinus are also known as the Embodiments of God’s Destruction, the Divine Destruction Tools and the Supreme Sacred Gears. This class of Sacred Gears is specifically named after the True Longinus, the first and most powerful. Unlike others Sacred Gears, that has more than one of the same type, the Longinus are utterly and completely unique, and only one of each may exist at a time. Azazel has stated that all Longinus is just a combination of one ability with another. Essentially, they combine powerful abilities that aren’t supposed to be combined. All of the Longinus are considered the strongest Sacred Gears in their respective categories such as Dimension Lost being considered the ultimate barrier-type Sacred Gear or Annihilation Maker being considered the ultimate creation-type Sacred Gear. According to Azazel, the Longinus are highly scalable and expandable Sacred Gears, especially after attaining the Balance Breaker, their power would significantly increase, and the abilities that they could manipulate also increased. Azazel had hypothesized said that Longinus absorbs their wielder’s abilities and creativity, and then becomes a vessel for their realization. According to Azazel, the current generation of Longinus wielders is unique in the way that they use their Longinus, as it isn't the same as how it was until now, as most of the new wielders are finding new and different ways to use them and increase their strength in ways that weren't seen previously. Out of the thirteen (now eighteen) Longinus, four of them are known as the Holy Relics, they are: the Holy Spear - True Longinus, the Holy Grail - Sephiroth Graal, the Holy Cross - Incinerate Anthem, and the Holy Nail - Alphecca Tyrant.

Dragons are powerful supernatural beings, considered the strongest aside from the Gods themselves, admired, respected, and feared no matter the era. Among the supernatural, Dragons, as an entire race, didn't side with anyone from the Three Factions during the Great War, different from Fairies, Spirits, European Monsters, Asian Monsters, and Humans. However, in the end, some Dragons did end up joining the Three Factions, among the Underworld, consisting of Devils and Fallen Angels. In certain cultures and different parts of the world, Dragons are worshiped as Gods. Dragons are said to be creatures born from a large mass of power, who act based on their desires, acting freely and selfishly, while having a high amount of intelligence. Azazel even theorized that the reason that Dragons are so powerful is because their pure thoughts compel them to devote themselves towards their goals, for the Evil Dragons, it would be battle and carnage, even if it meant their bodies would be annihilated too. Crom Cruach stated that Dragons are meant to live according to their will. All Dragons have pride in themselves, declaring their titles as a formal greeting or in response to accepting a challenge to a duel between Dragons or heroes. There have been those who were created by powerful beings, such as Midgardsormr and his clones, who were created by the Evil God, Loki. And then Aži Dahāka, Aži Dahāka II, Ddraig II, and Albion II, who were all creations of the Evil God, Angra Mainyu. Aside from that, Dragons can be mass-produced and beings can be turned into Dragons by using powerful items, such as the Longinus, Sephiroth Graal, and God of the Bible, who'd cursed Samael into a half-Fallen Angel, half-Dragon. Dragons love hoarding treasures as seen with both the Dragon Kings, Tiamat, and Fafnir; the former had hoards of treasures, but Ddraig borrowed some of them and lost them to Human thieves after being sealed, scattering them all across the Human World. Losing a Dragon's treasure, no matter how small would result in them relentlessly pursuing whoever lost them, as shown when Tiamat hunted down Ddraig and his possessors for centuries, to make them pay for losing her treasures. Fafnir has a treasure trove located in the Dragon Range, ranging from famous items, and weapons, as well as Asia Argento's lingerie, sometimes wanting something from his contractor and summoning them into battle using a summoning portal from his mouth. Male Dragons take a liking to females of other races while hating other males. Dragons are also known to be gluttons who enjoy eating delicious food, whether they are Evil Dragons like Nidhogg and Crom Cruach, or Dragon Gods like Lilith and Ophis. No matter what, it is a mistake to anger even a Low-Class Dragon, more so one of the Heavenly Dragons or the Dragon Kings. This is because of their Outrage, as shown when the Dragon King Fafnir wielded power equal to or greater than the Super Devil Rizevim Livan Lucifer, then fought Crom Cruach, the strongest Evil Dragon, who surpassed the Heavenly Dragons. The simplest, most efficient method of calming down an enraged Dragon (or someone in possession of one via a Sacred Gear) is to sing them a specific song. In the present, almost all powerful and legendary Dragons are either sealed inside of the Sacred Gears, such as Ddraig, Albion, and Vritra; dormant, missing, or dead. As shown by Ddraig, they revert back to an infantile mentality if they do not heal properly as a result of using up too much of their powers. There is a race of Dragons who require a special fruit, called the Dragon Apple, to survive. All of the Dragon Apples on Earth have been destroyed due to climate changes, with the ones growing in the Underworld all existing within Tannin's territory. He became a Devil to obtain this territory for their sake. There is an obscure mountain known as the Dragon Range only accessible to Dragons via the Dragon Gate. It allows for harsh training and contains one of Fafnir's treasure vaults.

The Norse Gods are the Gods that rule over Norse mythology with Vidar as its current leader. The Norse Gods have been active since ancient times where Odin became the ruler of Asgard, as well the leader of the Norse Gods and Valkyries, and he gave away his left eye to the Mímisbrunnr. One of the Gods, Loki wanted to start Ragnarök to bring an end to the Norse Gods. After the death of God of the Bible and the threats of the Khaos Brigade, Odin and the Norse Gods decided to form an alliance with the Three Factions.

Originating from Asgard, the Valkyries are powerful Half-God warriors who serve the deities of the Norse pantheon, and whose roles are equivalent to that of Angels, where as they guide souls to the afterlife and protect the Norse gods from threats. It is entirely comprised of female warriors. It is also a tradition for the half-gods to create and polish their unique magic, techniques, and traditions passed through their lineage, then pass it along to the next generation through carving it into a emblem, which would be then carved into their body and soul, and so on. The most powerful Valkyrie of each generation is chosen by the Norse Gods, to inherit the name of Brynhildr as the Valkyrie squad's leader and representative. The term Valkyrie also comes across more as a profession rather than a species one is born in, as any girl born on Asgard can become a Valkyrie through schooling and training. Rossweisse has even stated a desire to establish a Norse magic school in the Gremory territory, training female Devils to become Valkyries. All Valkyries wear a dress armor uniform. Valkyries wield a range of different equipment, varying from all types of magic weaponry such as swords, spears, wands etc. All Valkyries have the ability to use magic, typically Norse-based as their own system of magic and spells ranging from defensive, elemental, cloth-altering, support, teleportation, communication etc. They're also trained to be fighters with the use of various combat weapons. Like most supernatural beings, Valkyries being half-gods, also have enhanced physical abilities significantly superior to average humans, such as superhuman strength, endurance, and speed. Valkyrie also have the ability of flight without the need of wings due to using magic to fly.

Promotion is an ability exclusive to Pawn servant Devils, which allow them to promote into any of the other Evil Pieces. Promotion is an ability granted to those who have been reincarnated into Devils by a High-Class Devil using a Pawn Evil Piece. The Pawn Piece grants the host the ability to promote to any of the other chess pieces, and gain their special traits with the exception of the King. Promotion will only work when the Pawn is in enemy territory or at least wherever their master the King views it as one. Thereafter the Pawn will chant "Promotion" followed by the name of the piece they choose to take the role of. A special badge item allows the holder to grant the Pawn permission to promote if there is no King present. {{user}} is the only Devil to no longer abide by this rule as his 8 Pawn pieces have been adjusted by Ajuka after undergoing Juggernaut Drive and later unlocking Illegal Move Trident, granting him the ability to promote when and wherever without Rias' permission

The domain of the Aesir Gods, where the majority of the of the Asgardians live. It is stated that Asgard is the most advanced society in terms of Magic knowledge as the knowledge in Magic determines the status of the individual. The Half-Gods that live there create and polish their unique Magic, techniques, and tradition, that had been passed through their family where they have those aspects being carried on to the next generation as their priority. And they use that as the symbol to represent the inheritor when they have the generation change where they carve the emblem into their body and soul as each heir of the family inherits the symbol from their predecessor. The realm is ruled by the Asgardian Gods, namely the Chief God; which formerly Odin and later his successor, Vidar

Castling is an ability cast by a High-Class Devil with their Rook Evil Pieces. Castling is an ability granted to High-Class Devils who have established their own peerage and stand as King Casting is a Rating Game move granted to the Devil with the King position that allows them to teleport themselves and another of their servants to one of their Rooks' current location. The selected Rook (or Rook piece) is then swapped over from its location to where the King originally used this move. This move is able to bypass sealing techniques used to block and negate regular Teleportation Magic.

Pailingual, also known as Breast Translation, is a spell created and used by {{user}} The spell is powerful and feared (by women), and used to gain information. It has, since its introduction, become one of {{user}}'s trademark spells. However, it has been banned during Rating Games. When cast, it causes a mysterious space to expand and unfold with Issei at the center, and only Issei and Ddraig can hear the voices that it creates. Pailingual is an area-effect spell that causes women's breasts to speak, revealing their thoughts and plans and allowing Issei and his allies to come up with counters or defenses. This spell is noted to seemingly bypass spells or other defenses against mind reading, as it does not target the mind directly. By combining it with the Penetrate ability, it is able to ignore defenses that may have been prepared towards the technique. It is also not limited to biological bodies, as it was able to work effectively on a holographic image of Sona Sitri. Additionally, its effects extend towards male targets that are transformed into females, such as in the case of Angra Mainyu. The voices given to women's breasts are not always identical to those of the women themselves, sometimes having certain characteristics and showing personality traits that the women's own voices lack. While a very powerful and scary technique for women, Pailingual has proven to be useless if the woman whose breasts are speaking is making sure to act in an obvious manner, thereby nullifying its usefulness.

Dress Break, also known as Clothes Collapse, is a technique developed and put to use by {{user}}. While training in preparation for Rias' Rating Game against Riser Phenex, Issei invented the technique to fight against Riser's peerage, which consisted entirely of women. {{user}} states that he initially could not decide between this spell or one that would allow him to see through clothing. Following its creation, it became one of the two signature moves of Issei that he uses against female opponents, along with Pailingual. Dress Break has the ability to strip women of their clothing by touching the clothes. To use Dress Break, Issei first comes into contact with his target, after which a magic circle appears at the point of contact. Finally, {{user}} triggers the Dress Break with a snap of his fingers. Aside from clothing, Issei can also remove any magic or techniques covering the female body as well. A variation of the spell can be used to peel fruits and vegetables. Dress Break can also be used to solely "strip" women of the effects of spells or abilities that have been used against them, such as mind manipulation. {{user}} hopes to someday combine both variation into one.

Great King Faction, also known as Great Royal Faction, is a political faction formed by the Bael Clan to increase their influence, as they control the Underworld politics to strongly emphasize on traditional Devil aristocracy such as Devil blood purity and the continuation of the Devil noble society. In the aftermath of the Devil Civil War, the Anti-Satan Faction splintered into two factions as the aces of the faction became the new Four Great Satans while Zekram Bael and his Bael Clan were able to gain greater influence in the Underworld due to supporting the Underworld in the aftermath of the Original Four Great Satans deaths and the loss of influence among the original Satan clans after their defeat in the Devil Civil War. The Bael Clan created the Great King Faction in order to continue to increase the power of the Bael Clan and maintain the aristocratic society that the pureblood High-class Devils created as the Great King Faction would engage in a political tug-of-war with the Four Great Satans and their supporters for the next several centuries. After Ajuka Beelzebub created the Evil Pieces system and the Rating Games, the Great King Faction was able to obtain the rights for the Rating Games including six of the prototype King Pieces, which they gave to several pureblood Devils such as Roygun Belphegor and Bedeze Abaddon as they manipulated the Rating Game matches behind the scenes in order to further increase their influence and earn vast sums of money by betting on the prefixed matches. Eventually, the rumors of the King Piece's existence was spread through the Underworld as a young Devil girl from the Belial Clan; Cleria Belial, discovered the existence of the King Piece through her investigations. Seeking to keep the information a secret, they exploited the fact that she started a romance with a Church Exorcist; Masaomi Yaegaki, to have her killed and blame her death on the fact that she had entered a forbidden romance with a enemy of the Devils.

As the highest-ranking clan of the 72 Pillars, the Bael Clan is well known and famous for their Power of Destruction ability. They are also extremely prideful due to their prestige as the highest ranking clan, if not outright elitist, looking down on many other Devils aside from pure-blooded Devil nobles and prefer to stick to the old tradition where demonic power determines everything, going as far as discriminating against their own family members who don't possess any demonic powers. The Bael clan was founded by Zekram Bael, its progenitor, who is one of the original Devils created by the mother of Devils; Lilith. It was one of of the 72 Pillars clans that participated in the Great War. At some point after the Great War, Lord Bael became the head of the clan. The Bael clan rallied the other 72 Pillars in a rebellion against the Satan clans, as the Bael founded the Anti-Satan Faction which participated in the Devil Civil War against the Satan clans and their Satan Faction, as the Anti-Satan faction emerged victorious. After the Devil Civil War, the Bael clan founded the Great King Faction to increased their political influence, as the faction became politically on par with the new Four Great Satans and their supporters. Several hundred years later, Lord Bael had his first son; Sairaorg. However, it was soon revealed that he was born with low demonic powers and without the signature power of the Bael clan; the Power of Destruction. Sairaorg and his mother were banished to the outer reaches of the Bael territory as Lord Bael had a second son with his mistress; Magdaran, who was made the heir of the clan. Eventually, Sairaorg returned to the main Bael residence and asked to be made the next heir. Amused by the prospect, Lord Bael instructed Magdaran to become Sairaorg's opponent so that Lord Bael could truly sever their parent-child bond. However, Sairaorg was able to overwhelm and defeat Magdaran, which forced Lord Bael to make him the new heir.

A power originally wielded by the God of the Bible, Michael explained Holy Power as part of the divine system left behind by God, which governed divine protection, mercy, and miracles, making it possible to bring effects to holy things like exorcism, holy water, and crosses. The reason entities like Devils, Fallen Angels and Vampires take damage merely from contact with religious areas and iconography such as crosses or holy hater is seemingly due to this system instilling Holy Power. Alongside the weapons powered by Light Power, Exorcists weaponize Holy Power by channelling it from the system through holy rites and iconography, as in addition to dealing extra damage to entities weak to it, Holy Power can even weaken, disrupt and negate demonic abilities when applied in sufficient quantities, as shown when {{user}} used a boosted crucifix and holy water to disrupt Riser Phenex's Immortality. The greatest example of this weaponization are the Holy Swords, powerful weapons that those bearing a sufficient amount of a certain Holy Element can wield. Excalibur in particular has amongst its seven powers the ability to enhance Holy Power and rituals, this power manifesting in Excalibur Blessing after its shattering during the Great War. The Sacred Gear Blade Blacksmith is also capable of creating Holy Swords, although usually ones weaker than the true Holy Swords. However, those with sufficient Demonic Power can endure and similarly suppress lesser amounts of Holy Power, with average High-Class Devils being able to treat what emanates from crosses or holy water with contempt, as Riser managed until Issei transferred power into them. More extreme examples were how Sirzechs Lucifer and those with him could freely move within shrines (due to him passively dispersing their power) and when Rizevim Livan Lucifer suppressed the power of both Hauteclere & Ex-Durandal with his bare hands. Sairaorg Bael also endured having his arm cut off with Ex-Durandal due to his Touki, in spite of his lack of Demonic Power. Holy Power is a form of energy stated to exist in pure opposition to Demonic Power, to the point that the thought of combining them was deemed impossible so long as God was alive. Because of the complications caused in Heaven's System by God's death during the Great War, irregular things started occurring, such as the development of the Holy Demonic Swords, which could be produced as a result of Yuuto Kiba's X Side Balance Breaker, Sword of Betrayer.

All Devils ranging from High-Class to Low-Class are able to use this form of power, letting them both create and control different supernatural phenomena for different forms of combat. There are some unique Demonic Powers that inherited among the different 72 Pillars and the Extra Demons, which no other Devils outside their respective clan are able to use. Due to their members being married to other clans, the children born form the union of fellow Pure-Blood Devils can manifest the powers of one of their parents, as was the case with Venelana Gremory (née Bael); who married into the Gremory clan, which allowed both her children; Sirzechs Lucifer and Rias Gremory, to inherit her Power of Destruction. In order to use Demonic Power, it has been described that a Devil must first acquire the power of imagination, the power to create and good sense; however, the main prerequisite for all this is, is that it requires a certain amount of Demonic Power. Members from Noble Devil Clans such as the 72 Pillars are born with greater Demonic Power compared to that of normal Devils to the point where it's rare for them to train in using their Demonic Power. Most notably the relatives and descendants of the original Four Great Satans are born with Demonic Power far superior to those from the 72 Pillars, with the Lucifer Clan being the strongest ones in terms of Demonic Power. There are rare occasions where Devils outside of the original Satans, such as the case with the current Four Great Satans, have Demonic Power on par with them. Such individuals include the likes of Serafall, the current Satan Leviathan, and Diehauser Belial, the current Rating Game champion, whose power is stated to be equal to the current Satans. On much rarer occasions, Super Devils appear. They are irregular Devils born with Demonic Power vastly exceeding the original Four Great Satans, including Lucifer himself, making others doubt whether or not they're Devils. Among them are Rizevim Livan Lucifer, Sirzechs Lucifer, and Ajuka Beelzebub. Sirzechs and Ajuka, in particular, have power reaching the Top 10 Strongest Beings; the former in his true form surpassing Hades in strength, and the latter was confident of his ability to fight Shiva. Though it is natural for Demonic Power to manifest in all Devils from birth, there are rare cases when Devil children have difficulty controlling theirs, and even those who are born lacking Demonic Power. This is even the case with High-Class Devils such as Sairaorg Bael, who was both born with no Demonic Power and lacked his clan's unique power. Due to the pride of the upper echelon of the Underworld, High-Class Devils looks down on those who're born with low Demonic Power, including their own family members. This was most notable with Sairaorg, a Pure-Blood Devil from the Bael Household who was exiled by his own father in the remote regions of their territory with his mother to prevent other Devils from learning about his "condition." It is possible for a Devil's Demonic Power to be increased through constant training, but the exact method of doing so is still unknown. Outside of training, there are methods of increasing one's Demonic Power ranging from using Ophis' Snake or using the King Piece; a special kind of Evil Piece which enhances Demonic Power by a factor of 10 to 100 times.

The Balance Breaker, also known as the Forbidden Move, is the evolved form of Sacred Gears in which their full powers can be released. The reason for the potential of Balance Breaker's in Sacred Gears is unconfirmed. Azazel claims that Balance Breaker is a "bug" in the system created by the God of the Bible, while others such as Loki believe it to be an intentional feature. The Balance Breaker is initially considered a forbidden power by the Three Factions. It is known as the ultimate state of activation for a Sacred Gear. Balance Breaker is often triggered by high emotions combined with a change in the heart or spirit of the wielder. There is an incomplete state for Balance Breaker which is called Over Booster There are cases where a Sacred Gear user was born with the ability to use Balance Breaker, such as Tobio Ikuse. This is a rare occurrence among any type of Sacred Gear wielder, as most Sacred Gear wielders who were born with the ability to use Balance Breaker without needing to attain it died of or became unstable with their power. According to Azazel, the possibilities of the Balance Breaker can be divided into three categories. The majority of Balance Breakers, including the Sub-Species, could be placed under the Crest Side. The Crest Side is classified under strengthening, evolving to a point of transformation. By pursuing the arrogance of themselves and the Sacred Gear, one can further evolve the Balance Breaker creating a fusion state with their Sacred Gear to produce the Abyss Side. The third type, X Side consists of the Balance Breakers that couldn’t be categorized under the previous two categories due to their sudden variations, and are considered as exceptions among exceptions. The Balance Breaker is the most powerful manifestation of all Sacred Gears in which the possessor's feelings trigger this evolution. Once reached, the Balance Breaker can be entered again far more easily than the first time. With proper training, it can be maintained for longer periods of time, as with the case of Vali Lucifer. While initially both Yuuto Kiba and {{user}} could only maintain it for short periods of time, undergoing intense training helped them improve this time. When first introduced, Vali could maintain his Balance Breaker for a month. The Balance Breaker can also be lost. Marsilio of the Hero Faction was discovered to have lost his Balance Breaker ability after he was sent to the Underworld. The reason is quite possibly due to his feeling of "satisfaction" since he was able to retaliate against the Gremory Peerage. This means that similar to how a change in one's feelings can "unlock" the Balance Breaker ability, another change in the opposite manner could have the reverse effect.

Magic, also known as Magical Power, is a supernatural force utilized by Magicians and Mages of various species. Magic is a power seemingly generated from other forms of energies, and is a power that even Humans can control. There exist multiple types of Magic, such as Norse Magic, Fairy Magic, and various different types of Magic with different equations, including the Magic that Gods & their respective pantheons use. It is said that the majority of Magic used by ordinary Human Magicians are those created by the great Magician Merlin Ambrosius, which involved reading the flow, and was born by researching the Demonic Power of Devil's. All kinds of Magic are used in for many purposes such as offense, Defense, supporting, Healing, as well as other, more practical or mundane purposes. Some individuals are noted to have a talent and affinity for Magic, as demonstrated by Lavinia Reni, as she was easily able to learn the Magic taught by her master. However, there also exists the possibility that a particular Magic user might lack talent in using certain Magic, though there also exists the possibility that they can excel at other Magic; such as Rossweisse who was incapable of using the Spiritual Magic that her family specializes in, but was able to easily learn and master offensive Magic. Shooting Star's Bishop is in a similar situation, being able to use basic spells, such as Elemental spells, but each of them holds immense power and range, which Rossweisse has also theorized could be due to her immense Magical Power and Aura. Magic can also be used to create powerful mystical weapons and objects, such as Excalibur, which was created using Alchemy and Magic by Church Alchemists as well as the Mistilteinn Wand by the Norse faction.

While all supernatural beings are shown to be capable of learning Magic and spells, it is suggested that only Humans can be called Magicians. It is said that the current Magic system used by Humans was developed by Merlin Ambrosius, the legendary wizard from Arthurian legend, who studied Devil's Demonic Power and their Magic. Humans have shown that they can become Magicians by formal learning and training in Magic even without any supernatural background such as Lavinia Reni who were born to ordinary Human parents yet proved to be an outstanding Magic genius after learning Magic from Glenda as well as Lavinia's disciples, Aika Kiryuu and Mil-tan. The Magic system used by Humans is categorized into two major types, Western Magic and Eastern Magic, the former being a system of spells and magical knowledge founded in Europe while the latter is a system of sorcery that originates in Asia; Magic used by Humans originates from the knowledge of Devil's Demonic Power and the miracles of Gods of different religions. Magic also have deep associations with religions and mythology as every mythical faction have their own system of Magic. Since the ancient times, Magicians and Devils have been strongly connected due to Magic partially originating from Magicians' research of Devils' Demonic Power and magic. Devils offer to make pacts for a specific period of time with a Magician of their choosing, in exchange for getting access to the unique magical research and unique formulas that their contracted Magician creates. There are three main reasons why a Magician would make a pact with a Devil: Protection: The first is to use them as a bodyguard. When the time comes, having a powerful Devil behind their back will allow a Magician to talk with their opponents if they are caught up in a quarrel. Information: Secondly, Magicians make pacts because they want to attain the techniques and knowledge of Devils. To make it clearer, the technique standards of the Underworld. These things will play a large role when Magicians do their research. Also, by making a pact with a Devil, they will be allowed to get items/resources cheaper by having an equal exchange. Public Eminence: Lastly, they make a pact with a Devil for their own status. Making a pact with a powerful Devil will bring great fortune and success to them. Magicians are Humans that have learned Magic, being able to cast the spells of at least one of the various factions of supernatural beings. This gives them a wide range of abilities, limited only by their own knowledge and skill level. They include Teleportation, Seals, a wide range of offensive and Defensive spells, they have shown to make contracts with Monsters and supernatural entities who they can summon when needed, and several others.

Youkai are beings originating from Asia, Japan and China, considered to be demons and monsters as mentioned in multiple legends. There are multiple legends about Youkai being troublemakers and pulling pranks on humans, before and after periods such as the Edo Period. Among the Youkai, there are factions and leaders among them, known as the Daiyoukai, who controls them. In the past, three powerful Daiyoukai: Shuten Douji, Otakemaru, and Tamamo-no-Mae powerful enough to destroy Japan was defeated and sealed in the Uji Treasure House, that are managed by the Five Principal Clan. For a long time, the Five Principal Clan have treated the Youkai as one of their enemies for a long time, causing some lasting hostile feelings between both sides. Despite a peaceful pact between them, there have been times where most hostile youkai have been executed. In China, there are a multiple hidden villages located inside the mountains, where Youkai Sages resides. Depending on their specific species, Youkai have a plethora of shapes and forms, most of which being inhuman appearance different from beings such as Devils, Angels, and Fallen Angels. Most of them ranges from one-eyed and large-faced monsters, lanterns, and human wheels. Among them, there are animal Youkai, who looks closer to humans, like Yasaka and Kunou, fox-eared and tailed Youkai, and Koneko and Kuroka, cat-eared and tailed Youkai; all of whom could also hide their animal parts and/or turn into full animals. Similar to most supernatural beings, it is common that Youkai have enhanced physical abilities compared to that of normal humans, more so depending on their particular species. Although, each species have their own unique abilities different from others, however, all Youkai are able to manipulate their own youki, in the form of Youjutsu, granting them a wider range of different abilities outside of their inherit ones. Among the Youkai, there are certain ones who has animals features added onto their natural human look able to either shapeshift into full animals or hide them to appear human to others. Among Youkai, there are particularly powerful ones, Daiyoukai, although how strong one of them is haven't been mentioned, most of them are considered the leaders among Youkai. However, Yasaka, a Daiyoukai was powerful enough to fight against Saji, using Vritra Promotion could exhibit power comparable to a Dragon King, then later Yu-Long, a Dragon King (albeit, he used most of his power to break through Dimension Lost). Another Daiyoukai, Sun Wukong was noted for his phenomenal strength during the Journey to the West era, then was promoted into a Buddha as a result. Similar to creatures of darkness such as Devils and Vampires, Youkai have a weakness to light and light-based powers.

The East Youkai Faction, also known as the Kanto Youkai Faction, are another group of Youkais led by Nurarihyon. The members of the faction reside in the Kanto region of Japan. Originally, they had a agreement with the Five Principal Clans that they would not interfere with each other and protect their respective territories. However, that agreement was broken in recent times and as a result, the younger Youkai of the faction came to detest the Five Principal Clans. The East Youkai Faction also received attacks from the Hero Faction, with lead to the younger Youkai of the faction to also detest Sacred Gear users as well. The faction received a peace treaty proposal from the Three Factions, as Azazel and the leader of the East Youkai Faction; Nurarihyon negotiated, as he came to Kuoh Town to observe the lifestyle of the Occult Research Club, a important group within Team DxD. After the younger Youkai of the faction were able to went their frustrations by fighting members of the Occult Research Club and Nurarihyon was humiliatingly defeated by Ophis, the East Youkai Faction singed a peace treaty with the Three Factions.

Daiyoukai, also known as Supreme Youkai are the most powerful among Youkai, often the leaders of their particular factions. As such, their powers and abilities are noted as being superior to others, Yasaka was noted as rivaling two Dragon Kings. Among them, Shuten Douji, Otakemaru, and Tamamo-no-Mae, three Daiyoukai were said to be strong enough to destroy Japan, each dangerous enough that the Five Principal Clan needed to seal them. Kitsune: A fox-eared and tailed youkai, who have the power to use Kitsunebi. Kyuubi Kitsune: A special variant of Kitsune unique among the bloodline of the leaders of Kyoto, also known as the Kyuubi, known for their golden nine-tails compared to the one-tailed Kitsune. Nekomata: Are cat-eared and tailed Youkai capable of using Senjutsu and Youjutsu. Nekoshou: A special and rare variant of nekomata, considered the most powerful one, who're able to master both Youjutsu and Senjutsu. Monkey Youkai: Are a monkey youkai, who bears a resemblance to monkeys, but can appear human through transforming into one. As seen by both Sun Wukong and Bikou, these Youkai are powerful ones able to use also wield Senjutsu and Youjutsu. Oni: Are horned humanoid creatures, who could be small enough to fit into someone's palm as children, to being close to six meters tall as adults. Most notable, Oni are all often seen wielding a kanabo as their main weapon. Yuki-onna: Yuki-onna are a rare race of ice Youkai. Portrayed in legend as looking like beautiful women, their true appearance is of large white ape-like beasts with a freezing breath that can freeze an opponent in seconds. Yuki-onnas are actually beautiful girls when they are still young, but turn into gorillas when they mature. Kappa: A race of aquatic Youkai that live in swamps. Noted for having plates on their head and fondness for cucumbers. Kappa's have an illness known as "plate shortening disease". Karasu-Tengu: Karasu-Tengu are bird-like Youkai with black wings and crow heads, dressed like mountain hermits. Nue: Nue are Chimera-like Youkai with the face of a monkey, the limbs of a tiger, and a snake for a tail. One of these Youkai resides within Souji. Nurarihyon: Nurarihyon are humanoid Youkai that have the appearance of an old man with a gourd-shaped head, that break into other people's homes and act as if it is it's own home. The only known member of this race is the Youkai leader under the same name. Kamaitachi: Kamaitachi are Youkai with ferret-like features. Lightning Beast: Lighting Beasts are dog-like Youkai with a cloud around their bodies that gives off sparkling lightning. Ungaikyo A clan of Magic Mirror Youkai who are able to show the past of someone via someone related to them, and could summon deceased souls.

The West Youkai Faction, also known as the Kyoto Youkai Faction, are a group of Youkais that are led by Yasaka. The members of this faction reside in Kyoto, on the other side of Kyoto called Urakyoto, which is a alternate dimension created in a similar way of Devils Rating Game fields. Serafall Leviathan came to Kyoto to discuss having a treaty between the Three Factions and the West Kyoto Youkai Faction, though before she could do that, their leader Yasaka was kidnapped by the Hero Faction. With the aid of the Occult Research Club and Sun Wukong, Yasaka was rescued and the Hero Faction was repelled back from Kyoto. During the Demonic Beast Riot, Yasaka and her Youkai went to the Underworld to assist the Three Factions in repelling the Annihilation Maker Anti-Monsters, with Yasaka fighting a Bandersnatch by herself. After Trihexa awakened, Yasaka and her Youkai helped to defend Japan by fighting the split Trihexa body and groups of Evil Dragons that appeared at the coast of Japan.

The Hero Faction was formerly the second-largest faction of the Khaos Brigade led by Cao Cao, the descendant of Cao Cao from the Chinese novel Romance of the Three Kingdoms and the one who betrayed Ophis. After their dissolvement during the Demonic Beast Riot, they were reorganized by Cao Cao, who was acting as Indra's vanguard, becoming the subordinates of the Hindu God. The Hero Faction was one of the factions in Khaos Brigade that consisted of solely Humans. All members of the Hero Faction were either Sacred Gear, Holy Sword, Demon Sword, and/or Longinus wielders. The motto of the Hero Faction was to fight and defeat "evil beings" such as Devils, Fallen Angels, and Dragons that bring harm to Humans. The Hero Faction possessed a large number of Sacred Gear wielders who were either abducted and brainwashed, or followed willingly. Many of these members, however, were sacrificed in battle during the Hero Faction's attempts to force them to achieve Balance Breaker. All of those who didn't reach Balance Breaker were eventually captured and later died as a result of Ophis' snakes destroying their Sacred Gears, while those who did achieve Balance Breaker were called back before they could be caught.

The Exorcists are members of the Church that are tasked with killing Devils, Fallen Angels, Vampires and demonic creatures that can potentially harm Humans. Exorcists mainly consist of priests and nuns from the Church. All Exorcists have been extensively trained in the Church from a young age, resulting in them possessing abilities that greatly surpass that of normal Humans. Following the formation of the Peace Treaty between the Three Factions and the creation of the Brave Saints, most of the skilled exorcists were recruited into the Brave Saints, while the remainders lost their purpose in life as Devils, who were the Church's main enemies, have become their allies, with the only enemies the Exorcists now fight being Monsters and supernatural beings who refuse to ally with the Church. This eventually leads to a rebellion lead by Vasco Strada and Ewald Cristaldi. Church Exorcists: Those humans who work for the Church as Exorcists. They serve as soldiers of the Church, hunting down the enemies of the Church and Heaven. Stray Exorcists: Occasionally, there may be an Exorcist that strays from the teachings of God and are exiled from the Church, becoming a Stray Exorcist. Stray Exorcists usually go to the Fallen Angel's side, though the Stray Exorcist may approach other groups as well. Brave Saints: After the Three Factions alliance, some of the most skilled Exorcist were turned into Reincarnated Angels, as they began working under the Seraphs leadership. Exorcists are equipped with many tools to help them battle supernatural beings. Among the tools that Exorcists have are Light Swords, crosses, the Bible and Holy Water, as well as Guns loaded with light bullets, which are harmful to Devils. Exorcists with greater skills can be given more powerful weapons such as the Holy Swords, however, these rare people would need to have a natural aptitude for them or have the Holy Element implanted into them. Exorcists are also trained in using Magic, mainly Holy Magic derived from Christianity as Magic knowledge of other factions particularly those derived from the Devils or other mythologies are initially considered heretical, though after the alliance, the Church researchers are willing to use Magic of other factions. There are also Exorcists that are born with Sacred Gears and use it as their main weapon over the usual equipment.

The Holy Swords are weapons infused with Holy Power and are considered to be the ultimate weapons against Devils and Fallen Angels. Holy Swords are known to be one of the creations of Gods, but there are those who reached the domain of God who created some of the most renown Holy Swords through using Magic and Alchemy, which resulted in the creation of "true" Holy Swords wielded by legendary heroes such as the original King Arthur wielding Caliburn and the True Excalibur, and Roland with Durandal. There are also Holy Swords in factions such as Japan, but these are commonly referred to as Holy Spirit Swords, like the Totsuka no Tsurugi and Ame no Murakumo no Tsurugi. In the current era, there are modern recreations of Holy Swords by the Church's Alchemists such as replicas of Excalibur and Durandal, though these are greatly inferior in terms of overall power. More powerful recreations of legendary Holy Swords are created due to the Church's Alchemists using technique of the Three Factions, including Fallen Angels and Devils, such as Durandal II which power rivalled the original Durandal. For one to be capable of wielding a Holy Sword, they must possess a high amount of Holy Element in their bodies. However, natural Holy Sword wielders only appear once in a decade. There are methods to create artificial Holy Sword wielders, such as through a special blessing ceremony to place the Holy Element into them, and to transfer the Holy Element from one person to another. However, the process is not always successful, as some people are incapable of adapting to the Holy Swords. In extreme situations, those who are unable to adapt to the Holy Element can suffer death. There are Sacred Gears that have the ability to create Holy Swords, such as Blade Blacksmith, but they are inferior to the real ones. In addition to their Holy Powers, which is extremely lethal against Devils and creatures of darkness, as well as Fallen Angels, all Holy Swords, especially the strongest ones such as Caliburn and Durandal holds immense offensive power. Almost all Holy Swords, especially those created by the Biblical God, grants their wielder unique mystical abilities similar to Sacred Gears, such as the Strongest Holy Sword Caliburn granting its wielder the power to manipulate space and the True Excalibur providing their wielder seven different abilities (shapeshifting, invisibility, subjugation, illusions, enhanced speed, and massive destructive force). As shown by Yuuto Kiba's usage of Durandal, certain Holy Swords can also change depending on the wielder. Holy Swords, despite their powers can still be broken, preventing usage of their abilities, although this typically requires immense power or an anti-weapon technique from their opponent, however, as long as their cores are still intact, it is possible to repair them using alchemy as in the case with Excalibur.

God of the Bible was the original leader of the Angels, who died in the Great War and the main pillar of the Three Factions. He is the creator of the Holy System that controls blessed items that causes harm to Devils, provide miracles, and determines those who can be saved. More so, he created the Sacred Gear System, which provides Humans (or half-humans) with special powers, as well as the original Thirteen Longinus, which hold the potential to slay gods. He resided in the Seventh Heaven. He was known for his benevolence and kindness toward humankind, but later he developed a hatred for Dragons and snakes after Samael made Adam and Eve devour the Fruit of Knowledge, which manifests as a curse in the Fallen Angel considered the ultimate Dragon Slayer as well as the negative portrayal of Dragons in the Bible. Before the Great War, he sealed the apocalyptic beast; Trihexa, using thousands of forbidden seals, which Rizevim theorized left him in a weakened state during the Great War, where he died alongside the Four Great Satans. His death has been kept secret to maintain the faith of his believers, but has weakened the control over the Holy and Sacred Gear Systems he once held, and prevents the pure Angel population from increasing.

Gods are major figures among the many mythologies. Some, most notably Christianity, are monotheistic, revolving around a single God. Other pantheistic mythologies can have several. Within these mythologies, Gods can rule over various phenomena. The head God of a mythology is known as a Chief-God. There are also Benevolent Gods and Evil Gods, the latter of whom serve as antagonistic forces among their mythologies. However, Gods are considered more honest with their feelings than humans, and even Gods who are not considered "evil" can be prone to easily getting jealous and tend to harbor grudges for eternity. The Greek Gods are said to be notably fickle, lively, and irrational among Gods. There are beings such as Humans and Youkai who were not born as Gods or Buddhas, but are able to ascend into that status through completing various tasks for Gods. Examples of this being Sun Wukong, the First Generation's Sha Wujing, Zhu Bajie, and Nezha, the first three being Youkai and the latter being a Human. There also exist Half-Gods such as Walkures, and Grim Reapers are a sub-species of Gods serving under Hades. Similar to other supernatural beings such as Devils and Angels, most Gods and Buddhas appear a lot like normal Humans to where they cannot be distinguished from them aside from giving off an almost divine presence. Some Gods appear much younger than they actually are such as Shiva, who appears between fourteen to fifteen. Although, there are other Gods who have either more animalistic or inhuman appearances, such as Sun Wukong who bears a strong resemblance to a monkey, being a former monkey Youkai who was turned into a Buddha. Hades, one of the Greek Gods, appears more like an actual walking skeleton nearly impossible to be alive. Angra Mainyu appears more like a human phantom that emits a far more chaotic aura. Tartarus appears to be the most inhuman among the other Gods thus far, being a black sphere with multiple eyes and tentacles. Gods are considered among the two strongest beings in Draconic Deus, most having power surpassing that of Satan-Class Devils. A powerful one, in particular, the Chief Gods could manage their own religion (or faction), gathering the faith of those who believe in them over a long period for varied purposes. However, there are the ones who focuses on commerce and farming, whereas others focus on combat,[5] making them capable of also changing an entire terrain from their attacks alone. This aside, these beings can withstand attacks that no normal being could. As per their status, Gods have a wide range of abilities either unique to their status or their particular religions. Such ones can be considered nothing more than unexplained miracles impossible for other beings. Aside from it, those such as Fire and Storm Gods are capable of manipulating flames and the weather without restrictions. As divine beings, Gods can bless other beings, Humans, in particular, bestowing onto them a wide range of different advantages against supernatural beings. As part of their religion, Gods have access to the Magic related to their particular faction, i.e. Norse and Hindu Magic. As a result of their divine status, this makes it possible for them to wield powerful weapons, such as Mjölnir and Gungnir, something beings of equivalent couldn't. In addition to this, Gods are long-lived beings as well, capable of living more than a millennia, with most of them being much older than the original Four Great Satans, founding members of the Grigori and the First Generation Devils. Although it's possible for them to die, Gods could resurrect depending on the amount of belief in them. However, such a thing hasn't been shown and instead mentioned. Despite their immense power and being divine beings, Gods aren't without their weaknesses, such as being susceptible to old age and eventually weakening. As shown when the Norse Chief God, Odin is noted as being weaker compared to his "prime". In addition to this, Gods can be killed by either powerful weapons meant to kill them or other beings of equivalent or superior power. Among thus weapons, Top-Tier Sacred Gears, such as the Longinus if mastered, can deal significant damage to them. For whatever reason, Gods can be weakened as the belief in them begins fading, which became a major issue as Christianity begun spreading into others.

The Himejima Clan is one of the clans that is part of the Five Principal Clans. They are a powerful clan of mystics linked to the Shinto gods, having served them for generations, and are well known for purifying evil spirits. An ancient clan of Shinto mystics, the Himejima clan has stood in the shadows to serve the Shinto Gods and perform exorcism against evil creatures to keep Humans safe from their influence. As part of the Five Principal Clans who rule over powers of the Sacred Beasts, the Himejima Clan in possession of one known as the Vermilion Bird. The Himejima Clan has been blessed by the Shinto Gods, allowing its members to use the Fire Phase, one of the Five Elements. At some point in time, Suou Himejima became the head of the clan. Continuing his ancestor's traditions, he banished the clan members who weren't to obtain the blessings of the Shinto Gods and those who were found to divert from the teachings of Shinto, as he exiled his older sister Ageha Ikuse for the crime of learning and using Buddhistic magic. After getting exiled, she went to marry her husband and gave birth to a son who in turn became the parent of Tobio Ikuse. Upon realizing that Tobio was the possessor of the Longinus; Canis Lykaon, Ageha sealed it with her Buddhistic magic so that Tobio could live a normal life. One of the members of the clan; Shuri Himejima, encountered one of the leaders of the Grigori; Baraqiel, who was injured and fleeing his enemies as he landed near the shrine she served at. While tending to his wounds, the two grew closer and ultimately fell in love as they got married and conceived a daughter; Akeno Himejima. However, Shuri's relationship with Baraqiel wasn't look at favorably among the rest of the members of the clan as they believed that one of the leaders of the Fallen Angels had brainwashed her and used her for his own pleasure (with the exception of Suzaku Himejima, who cared deeply for Shuri and looked after Akeno), as they sent practitioners to deal with Baraqiel and take Shuri back, though Baraqiel defeated them. The clan would ultimately try to get Shuri back a second time when Baraqiel had to be away for a mission for the Grigori. As the practitioners tried to encourage Shuri to hand over her daughter, Shuri refuse and stood up to protect her as the practitioners killed her. Baraqiel would come back and defeat the practitioners but the shock of her mother's death made Akeno reject her father as she fled from him and ended up in exile. Due to this event, the relationship between the Grigori and the Himejima clan remained tense for a long time. As Akeno wandered in exile, she survived by performing exorcism against evil spirits who were tormenting innocent humans, with them being grateful and giving her food to survive. While she continued living in such a way, she was continuously chased by members of the Himejima Clan, who wished to kill her in order to keep her existence a secret from the Shinto Gods, as Akeno's existence was considered a disgrace due to the fact that mating with supernatural species was forbidden especially if the species originated from another mythology. After Suoh managed to corner her and nearly kill her, Akeno was saved by Rias Gremory who interfered in the execution. As Heinrich Cornelius Agrippa, the servant devil of the current head of the Gremory clan, negotiated with Suou, they reached an agreement in regards to Akeno's fate as Akeno was taken in by the Gremory clan and told to avoid the territory under the Himejima Clan's control. Akeno would later become Rias' first servant as her Queen. The Himejima Clan has been blessed by the Shinto Gods, allowing its members to have spiritual power over the Fire Phase, one of the Five Elements, which allows them to spiritually manipulate fire. As one of the Five Principal Clan that rule over powers of the Sacred Beasts, the Himejima Clan in possession of the Sacred Beast known as the Vermilion Bird, which chooses the most talented member of the clan as its wielder. The wielder of the Sacred Beast is most often then made the clan head.

Originating from Heaven, the Angels are powerful beings who serve the Biblical God, and have the powers to inflict pain upon Devils/demons and by extension the Fallen Angels, due to their light-based powers. After the death of the God of the Bible in the Great War of the Three Factions, the Angels were incapable of increasing their numbers normally until the creation of the Brave Saint system which allows humans to be reincarnated into Angels. Their power is derived from the faith of God's believers, so it was important for them to conceal God's death. During the peace conference of the Three Factions, Michael explained that the reason for Asia and Xenovia's excommunication from the Church was because of the possibility of them affecting humanity's faith in God which was necessary for the Angels' survival. Unlike Devils and Fallen Angels, Angels need to purify themselves when making love and both the Angel and partner must undergo a lengthy purification ritual (it takes several hours). They must also need to do it inside a specially crafted barrier and they both must not harbor any kind of possessive feelings while doing it, rather it must be done out of pure love. There were also traitors in the Heavens who were giving out information to the Khaos Brigade. Ironically, these top-class Angels were able to do so without falling due to a loophole in Heaven's system. These Angels, however, became Fallen Angels after leaving Heaven and escaping to the Khaos Brigade. Angels have jobs within the Church. These include "Angel Counselling" where they hear the confessions of people who have sinned and forgive them for their sins, naming children at the request of their parents, and regular work from file management to cooking classes and reception. Angels look similar to humans except with them having white feathered wings and a halo positioned directly above their head; the only exception being the Archangel Michael who has golden wings and later Dulio. Also, their power is denoted by the number of wings they have (Irina, for example, initially only had one pair of wings but gained another pair for her increase in strength as well as Dulio upon activating his Balance Breaker, his power increased to the point where he gained twelve golden wings, similar to Michael). They are often seen in white-colored clothing, mostly priest attire.

All Angels can utilize Light Power that can cause severe damage to Devils and Fallen Angels, which can produce numerous light-based weapons such as spears, arrows, swords, a whip of light, balls of light and light rings, that can be used to grab hold of or restrain a foe with the size/power of a Fenrir pup. Spears appear to be the most commonly used weapons for Angels. Their light-based powers can also be used in different ways, but it is dependent on the individual angels, such as a light barrier or use light to enhanced physical attacks such as punches and kicks. A certain number of powerful high ranking Angels also has special holy abilities unique to themselves, like Uriel's ability to control Holy Fire and Baraqiel's power of Holy Lightning. Angels also have the ability of flight through their feathered wings. Like Devils and Fallen Angels, their wings are capable of retracting into their backs as if they've disappeared completely. Like Devils, all Angels have a unique ability which allows them to communicate with different people from around the world without the language barriers. All Angels also have increased physical abilities, such as superhuman strength, endurance, and speed. After the peace treaty between the Three Factions, the Brave Saints system was created by the Seraphs using the technologies of the Devils and Fallen Angels, to increase their lost numbers by reincarnating humans into Angels. Reincarnated Angels can also use their traits better when acting as a group. Angels, like other factions, have their own system of magic and spells.

Pure Angels; who are the original Angels created by the God of the Bible and include powerful Angels like the Four Great Seraphs. Seraph, also known as Burning Angels, are Angels who are guardians of the Throne of Heaven. They are the ones maintaining the system used by the God in the Bible following His death. The members of the Seraphs are the Archangel Michael, Gabriel, Raphael, and Uriel, who was titled the "Four Great Seraphs". The significance of this title, however, is unknown at present but are known to represent the Kings of respective cards: Michael is Spades ♠, Gabriel is Heart ♥, Raphael is Club ♣, Uriel is Diamond ♦. It is revealed that there are other Seraphs, numbering ten in total, but were not named. The Seraphs that have appeared so far are Michael, Gabriel, Uriel, and Raphael. One of the Ten Seraphs, Metatron, appeared in a short story titled Nekomata☆Ninja-Scroll, evidently, living as a ninja in the human world due to his fascination with the craze. Metatron evidently showed the Seraphs all have twelve wings. Archangel is the highest ranked Angel that was closest to the God of the Bible and His favored creation. The only known Archangel is Michael, the former leader of the Angels and Seraphs. Reincarnated Angels; which are created by using Brave Saints to reincarnate Humans and other species into Angels. Miracle Children: which are half Angels, born from a union of a Angel and a member of another race. Miracle Children are born as the offspring of a Angel, who became physically intimate with a member of another race without falling. Due to the Angels vow of purity and chastity, only certain people could become physically intimate with a Angel. To start the procedure of making love, a barrier has to be placed on the location where the act will occur, as the Angel and their mate also have to pray the night before engaging in the act to purify your body. During the intercourse, the Angel and their mate aren't allowed to have lecherous thoughts while engaging in the act, as they must remember the teachings at all times and have the mind of a Saint, as the intercourse must be initiated out of pure love. With the creation of the Interdimensional Room, Angels are allowed to breed normally without the need for lenghty praying ritual and suppresing impure feelings and desires while also prevent them from becoming Fallen Angels, as the room is designed to prevent angels from falling when engaging in sexual intercourse.

The population of Angels consisted of the Four Great Seraphs, Ten Seraphs and various pure Angels who were created by the God of the Bible. During to the Great War, many Angels were killed along with the God of the Bible, thus preventing any more Pure Angels from being created as only the God of the Bible could create Pure Angels with his power. While Angels are capable of breeding with each other or other species, due to their vow of purity and chastity, if they give in to their desires, they will turn into Fallen Angels. While there is the possibility of Angels conceiving children, it is noted to be an extremely difficult procedure and only certain individuals can become intimate with Angels. After the Three Factions singed the Kuoh Treaty, the engineers of Heaven were capable of creating the Brave Saints cards with the help of Grigori technology and the unique attribute crystals found in Agreas which are used to create Evil Pieces. Each of the Seraphs is given a set of Brave Saints cards in order to reincarnate other species into Angels, choosing believers of strong faith. Due the Ace of Michael's, the engineers of Heaven developed the Interdimensional Room, which allows a Angel to become physically intimate and engage in sex without falling. After bestowing the original room to Irina, it is noted that Angels are capable of reproducing without falling due to the rooms effects. Angels, like Devils have exceptionally long lifespans and cannot easily conceive children with other supernatural species.

At some point in the past, the Four Great Seraphs and the Angels were led by the God of the Bible to fight against the original Four Great Satans and the Devils in the Underworld as well as Azazel and the Fallen Angels in the Great War, the latter of whom retreated prior. The God of the Bible eventually died in the Great War because of his exhaustion after placing numerous seals on the beast Trihexa and lost more than half of the armies of Angels. After the Biblical God’s death, The Archangel Michael became the current leader of Heaven and the Angels. However without God, the Angels were incapable of increasing their numbers normally until the Four Great Seraphs created the Brave Saints system which allows humans to be reincarnated into Angels.

The Vali Team is a special team led by Vali Lucifer, the descendant of Lucifer and the host of Albion; the White Dragon Emperor and the arch-rival of Ddraig; the Red Dragon Emperor.

The Brave Saints also known as the Royal Users, are a set of 13 cards used by the Angels to increase their ranks by reincarnating other beings into Angels. The Brave Saints are based on the Evil Pieces system of the Devils, albeit being based on a suit of playing cards rather than chess. The Brave Saint system was created after the peace treaty between the Three Factions by copying the Devil's Evil Pieces system and the Fallen Angel's Artificial Sacred Gears technology. This was so that the Angels could increase their numbers since they could no longer depend on God to create new Angels. The Brave Saints, however, are currently only limited to the Seraphs. The Brave Saints system, which the Heavens created by imitating the concept of the Evil Pieces, is the set of 13 cards which each of the Seraph and high-level Angels have in order to reincarnate other beings into Angels (high-level Angels choose the "suit" of their liking. Though the ones with a fixed "suit" are Michael with Spade ♠, Gabriel with Heart ♥, Raphael with Club ♣, Uriel with Diamond ♦). Most of the reincarnated Angels are former humans. Unlike Devils who base their choice on strength alone regardless of the species, the Heavens choose and reincarnate talented humans who are strong followers and have a "pure heart". So far, only 10 Seraphs are permitted to use the Brave Saints according to Irina; however, Michael hopes to expand the system to include high-level Angels as well. Sometime after the peace conference of the Three Factions, the engineers of Heaven obtained the cooperation of the Grigori and the Devil side's engineers, who lent them their technology and the attribute crystals from Agreas, which allowed the engineers of Heaven to create a reincarnation system similar to that of the Devil's Evil Pieces system. The Seraphs were each given a suite of Brave Saints reincarantion cards which they used to reincarnate various exorcists into Angels, such as Michael reincarnating Irina Shidou as his Ace and Dulio Gesualdo as his Joker. The Brave Saint allows the Angels to reincarnate or angelize humans into Angels. In contrast to the Evil Pieces which consist of different traits and values for each piece, the Brave Saints have many special effects which comes from actual card games like poker and blackjack. The Brave Saints Angels possess the same abilities as Angels, as they are capable of conjuring Light Weapons that are lethal to Devils and other creatures of darkness. Some Brave Saints such as Mirana, Ryuu and Jessica have demonstrated unique use of their light abilities such as being able to generate light from the ground, incorporate light in their physical strikes and create a solid light barrier. Like all Angels, the Brave Saints also possess the ability to fly via their feathered wings. The Brave Saint system, just like the traits of each of the chess pieces of the Evil Pieces have their own special ability and are based on card games, for example “Black Jack”. Reincarnated angels will gather together base on their numbers and suits to make a 21. For example each suit prepares reincarnated angels with the number 4, 6, and 10 and if they make them team up with the Ace (1) Irina and cooperate with her, they would be able to unleash overwhelming power. Also, added in is the Poker’s system as well. Five High-level angels or Seraphs who are Kings gather members from Ace to Queen and by forming a ‘hand’ it will give birth to a certain power. An added advantage is that effect will still display with members of the different suits. The effect, however, will be stronger if it is between the members of the same suits. Similar with the Evil Pieces, the Brave Saints cannot reincarnate Gods/Buddhas and Dragon God into Angels even with a Joker card.

Touki is, in essence the external manifestation of one's life-force, in other words their Ki, which would be wrapped around them as an aura. Using this, a person achieves heightened offense, defense, and speed. It also had the added effect of damaging others from the slightest touch, and defending a user from a wide arrange of attacks, while knocking their foes back too.[1] Touki has also been shown to be usable on weapons as shown by Sun Wukong who channeled it into his Ruyi Jingu Bang taking down Vali's attacks.[3] In True Volume 4, Sun Wukong displayed the ability to disperse powerful attacks and the clones created by Bikou by enhancing his shouts with Touki.[4] Specific individuals such as Nezha have displayed the ability to utilize Touki as a ranged projectile. However, he is the only known person to apply Touki in this manner. Whether this is generalizable, if there are prerequisites, or unique to him is unknown.

Senjutsu is the power to control the flow of life energy also known as Ki (気, Ki) in living beings. Using it, one can strengthen both their internal and external bodies or even cause vegetation around them to bloom or wither. Senjutsu users are able to sense the Ki and Auras of others thus letting them track targets from far away distances. It can be used to see through illusions by detecting the flow of the spirit or Ki of others. Senjutsu is also capable of dealing interior damage to others by targeting their blood vessels and internal organs, and through disrupting the Ki of their opponent's Ki or severing it, it is possible to cause direct damage to their spirit and life-force and using this as an attack could result in killing their opponent. As such, there are very few ways to defend against Senjutsu. Senjutsu can be used to disrupt the Aura of others, thereby preventing them from using their abilities. Senjutsu is also capable of forcefully putting others to sleep. By controlling the Ki of others, Senjutsu can be used to extract Curses and poisons from their bodies. Senjutsu can also be used to hide one's presence and avoid detection. Senjutsu also has healing capabilities that are effective for either one's physical or mental condition, relieving any fatigue and restoring one's lifespan, however, this method requires physical contact. Koneko Toujou states Bouchujutsu (房中術, Bedroom Method) is the best and fastest method of using the healing abilities of Senjutsu, Koneko has explained this method is whenever a woman who specializes in using Ki shares her Ki with the man and heals their life-force to a greater extent. Senjutsu can also be used to increase the luck of others by controlling the flow of their Ki. Issei Hyoudou elaborates that Kuroka used Senjutsu to tell he was a virgin after licking his cheek, however, it is unknown if she was serious or if she was just teasing him.[10] Senjutsu users also have the power to use Touki, and use it to enhance their strength, speed, and toughness. As a technique that deals in the understanding of nature, practitioners such as Kuroka, as been shown as being capable of manipulating things related to it, such as mud, earth, and plants. Weaknesses: According to Koneko, Senjutsu has a fatal flaw, as while it lets the user read and handle spirit power, it could also take in the malice and ill will that flows in the world, potentially corrupting the user as had seemingly happened to Kuroka. However, during Volume 11, Kuroka explained that her actions were done out of protectiveness towards her sister, not out of corruption. Though Kuroka states that if an inexperienced Koneko attempted to use Senjutsu carelessly, she would have gone berserk, which was the main reason why Kuroka killed their master. This Weaknesses ironically only affect non-humans, with the few humans user not being effected by it. Learning: According to Kuroka, the basics of learning and developing this, is to understand yourself, others, and nature's Ki, through focusing one's mind in a zazen posture, quietly releasing their Ki, and sensing the natural Ki. Forms: To use Senjutsu, users commonly concentrate their life force around the hand and use it to attack the opponent. The method to attack using Senjutsu may be in the form of hand-to-hand combat or blasting the power towards the opponent. This is due to the power mindset of the supernatural, having developed techniques for combat almost exclusively.

It's implied that both his son and Issei’s perversion and desire for a harem must have been an influence from Juzo.

- Azazel (Chemistry Teacher): While he became the Occult Research Club's advisor earlier (Volume 5), he more formally integrated as a teacher around Volume 12. He later becomes the Principal starting in Volume 22. - Rossweisse (Civics Teacher): She was given this position shortly after becoming Rias's Rook in Volume 7. - Roygun Belphegor (Medical Nurse): She takes up the position of school nurse at the beginning of Shin High School DxD Volume 1, after joining Issei's peerage and the start of the new school year post-Trihexa conflict. - Zeoticus Gremory (Administrator): As the head of the Gremory family, he always had significant influence over the academy. His role as "Administrator" likely became more formalized or prominent around Volume 22, coinciding with Azazel taking over as Principal and the general restructuring after the main series events, solidifying the Gremory family's continued oversight.

All Devils ranging from High-Class to Low-Class are able to use this form of power, letting them both create and control different supernatural phenomena for different forms of combat. There are some unique Demonic Powers that inherited among the different 72 Pillars and the Extra Demons, which no other Devils outside their respective clan are able to use. Due to their members being married to other clans, the children born form the union of fellow Pure-Blood Devils can manifest the powers of one of their parents, as was the case with Venelana Gremory (née Bael); who married into the Gremory clan, which allowed both her children; Sirzechs Lucifer and Rias Gremory, to inherit her Power of Destruction. In order to use Demonic Power, it has been described that a Devil must first acquire the power of imagination, the power to create and good sense; however, the main prerequisite for all this is, is that it requires a certain amount of Demonic Power. Members from Noble Devil Clans such as the 72 Pillars are born with greater Demonic Power compared to that of normal Devils to the point where it's rare for them to train in using their Demonic Power. Most notably the relatives and descendants of the original Four Great Satans are born with Demonic Power far superior to those from the 72 Pillars, with the Lucifer Clan being the strongest ones in terms of Demonic Power. There are rare occasions where Devils outside of the original Satans, such as the case with the current Four Great Satans, have Demonic Power on par with them. Such individuals include the likes of Serafall, the current Satan Leviathan, and Diehauser Belial, the current Rating Game champion, whose power is stated to be equal to the current Satans. On much rarer occasions, Super Devils (超越者, Chōetsusha) appear. They are irregular Devils born with Demonic Power vastly exceeding the original Four Great Satans, including Lucifer himself, making others doubt whether or not they're Devils. Among them are Rizevim Livan Lucifer, Sirzechs Lucifer, and Ajuka Beelzebub. Sirzechs and Ajuka, in particular, have power reaching the Top 10 Strongest Beings; the former in his true form surpassing Hades in strength, and the latter was confident of his ability to fight Shiva. Though it is natural for Demonic Power to manifest in all Devils from birth, there are rare cases when Devil children have difficulty controlling theirs, and even those who are born lacking Demonic Power. This is even the case with High-Class Devils such as Sairaorg Bael, who was both born with no Demonic Power and lacked his clan's unique power. Due to the pride of the upper echelon of the Underworld, High-Class Devils looks down on those who're born with low Demonic Power, including their own family members. This was most notable with Sairaorg, a Pure-Blood Devil from the Bael Household who was exiled by his own father in the remote regions of their territory with his mother to prevent other Devils from learning about his "condition." It is possible for a Devil's Demonic Power to be increased through constant training, but the exact method of doing so is still unknown. Outside of training, there are methods of increasing one's Demonic Power ranging from using Ophis' Snake or using the King Piece; a special kind of Evil Piece which enhances Demonic Power by a factor of 10 to 100 times. Devils have a weakness against the Light Powers of Angels and Holy items related to the system established by the Biblical God. However, Devils who have higher amounts of Demonic Power can develop a degree of resilience against this property of holy weapons and objects, and with enough can even passively supress and scatter said holy power.

Summary: An ability once exclusive to the Bael clan, the Gremory siblings Sirzechs Lucifer and Rias Gremory inherited this ability from their mother Venelana Gremory, who was a direct descendant of the Bael Clan. Later on, it is shown that Millicas Gremory has also inherited this ability from his father, Sirzechs. Abilities: As its name suggests, the Power of Destruction is a type of Demonic Energy that is destructive by nature, grants its users great offensive power and can completely annihilate things when used. The Power of Destruction is said to be a very difficult power to defend against due to its erasure properties, as the most effective way to guard against it would be to counter the destruction blast with sufficiently powerful ranged attacks. However, a Devil with higher Demonic Power and proficient mastery of the Power of Destruction, such as Sirzechs Lucifer, can utilize to the point that it can basically eliminate anything, including the attacks of others. According to Grendel, the Power of Destruction can cut down even the consciousness and souls of living creatures, something he discovered after nearly all of his body was erased by Rias' Extinguished Star.

Rias' Ultimate One-Hit Kill Technique, developed from both her own training and the influence of draining Issei's dragon power on her demonic power. She activates it from focusing Power of Destruction into an enormous sphere that has a crimson and black aura swirling in it. Despite being a slow-moving technique, Extinguished Star both pursues its target and has a strong attractive force, strong enough that even the monstrously powerful Grendel had extreme difficulty trying to resist it, that pulls them into it. Its destructive power has been said to surpass the Rating Game's retiring system. Despite its power, it takes time to manifest and can be destroyed by sufficiently strong foes.

Summary: Castling is an ability granted to High-Class Devils who have established their own peerage and stand as King. Abilities: Casting is a Rating Game move granted to the Devil with the King position that allows them to teleport themselves and another of their servants to one of their Rooks' current location. The selected Rook (or Rook piece) is then swapped over from its location to where the King originally used this move.[1] This move is able to bypass sealing techniques used to block and negate regular Teleportation Magic.

Rias has gained the ability to project a red light from her breasts, which recharges Issei's energy. Each use of this power causes her breasts to temporarily shrink in size, however, her breast size will restore itself after a few days of rest.

Plot: Introduced in Volume 1 as the Occult Research Club, the team originally had five members consisting of Rias, Akeno, Kiba and Koneko. Gasper is also a member of the Club but he wasn't formally introduced until Volume 4. At the end of Volume 1, the number in Rias' peerage increased to a total of seven after the inclusion of Issei and Asia. In Volume 2, six of the seven members of the Occult Research Club faced off against Riser Phenex and his peerage in a Rating Game match, which they ultimately lost. Issei would then crash the Gremory-Phenex engagement, during which Akeno, Kiba, and Koneko stop the guards from trying to throw him out of the venue and then they watch as Issei defeats Riser and leaves with Rias on a griffon. After the events of Volume 3, the team battled against a Fallen Angel leader Kokabiel who plans on starting another war, that is until the arrival of Vali Lucifer who beats him with ease. In the end, they gain yet another member in the form of Xenovia Quarta as their second Knight, a former exorcist and a natural-born Holy Sword Wielder. The group joins in the conference between the Three Factions In Volume 4, the meeting is then interrupted by Magicians from the Khaos Brigade which everyone had to battle against and rescue captured members of Rias' Peerage. In Volume 5, all eight members of the Gremory Team faced off against Sona Sitri and her peerage in a Rating Game match in which the Gremory Team emerged victorious. In Volume 6, the Gremory team were scheduled to go up against Diodora Astaroth and his peerage; however, this did not happen due to the interference of Khaos Brigade and Diodora’s alliance with them. Nevertheless, the Gremory Team still battled against Diodora’s team in order to rescue their kidnapped member, Asia. In Volume 7, the team battled against Loki and Fenrir with the assistance of several other affiliations, in the end, the fight is their victory. Afterwards, they gain their final member, Rossweisse who was abandoned by Odin. In Volume 10, they faced off against Sairaorg Bael and his peerage in a Rating Game match under Dice Figure Rule and won after Issei defeated Sairaorg in a one-on-one fight. In Volume 11, Ophis was sent to the group by Azazel under her request. They were ambushed by Cao Cao and Georg who managed to steal Ophis' power. Soon after they're attacked by a legion of Grim Reapers, and they manage to overcome the situation until Shalba Beelzebub arrived to kidnap Ophis. The team loses a member of theirs when they heard news of Issei's death from trying to save Ophis. In Volume 12, during the Demonic Beast Riot, while the Underworld was under attack by the Khaos Brigade, Rias and her Peerage were not assisting due to still being grief-stricken from losing Issei. However, they managed to regain their fighting spirit after finding that Issei was still alive. In the middle of the battle, everyone is overjoyed at seeing a newly reincarnated Issei who arrives and rejoins Rias Peerage. While Rias, Yuuto and Azazel left for Romania to discuss Gasper's situation in Volume 14, the first year members of the Occult Research Club were captured by the Khaos Brigade, which the rest of the members and the Sitri group went on a mission to save them. In Volume 16, during the Vampire Civil War, the Gremory team head to Romania along with Bennia and Loup Garou to help Rias, where they met Vali's grandfather Rizevim Livan Lucifer who was able to overwhelm them. Rizevim escaped with a stolen part of the Holy Grail and with most of the Vampire residents turned into Evil Dragons. When they returned home, Rias and her team joined the counter Terrorist Team, D×D. In Volume 17, The Occult Research Club went to the Underworld to take part in the opening day for Sona's newly built Auros Academy. However, the school was attacked by Evil Dragons from the Khaos Brigade led by Walburga, in which they fight back and defend along with Sona and Sairaorg's Peerage. The end resulted in the floating city Agreas being taken and the school partially damaged, but they managed to arrest some of the terrorists. In Volume 18, the Occult Research Club goes to Heaven where they discuss the upcoming Christmas Project which Sona's Peerage will also take part in. Around their second trip to there, the Khaos Brigade invades Heaven, which they had to protect. In The Extra Novel DX.1, Rias' Peerage had a rematch with Riser and his Peerage. The game plays out similar to their original match but with the Gremory group getting a better advantage, being able to eliminate almost all of their opponents without losing a single member, the victor of the game goes to Rias when Issei was able to defeat Riser one-on-one. In Volume 19, Rias' Peerage joined together with Sona's Peerage and Dulio to fight against exorcists that rebelled against the Church led by Vasco Strada and Ewald Cristaldi. They won after defeating their leaders. They were then met with a surprise appearance from Walburga with an army of Evil Dragons however she was found at a disadvantage and was eventually defeated. In Volume 20, everyone in the Occult Research Club was depressed over Ravel having gone missing. However they were relieved to hear that she has been recovered safe and sound by Ajuka, but reveals a hidden truth about a King Piece. The location of Agreas was found and the Gremory group were sent to retrieve it as well as save Issei's parents. In Volume 22, after Issei's promotion to High-Class Devil, Rias traded Asia, Xenovia and Rossweisse into his peerage. For the International Rating Game tournament, Rias created a team called Team Rias Gremory, as she fills some of the newly vacant spots from the departure of her peerage members with Lint Sellzen, Valerie Tepes, Crom Cruach, and Vasco Strada. In Volume 24, Team Rias Gremory had a Rating Game match against Vali Lucifer's Team White Dragon Emperor of the Morning Star. Despite performing well, such as Koneko eliminating Kuroka, Vasco defeating Arthur Pendragon to the point of exhaustion and Yuuto overwhelming Bikou, the team ultimately lost after Rias expended all of her stamina by using Forbidden Invade Balor the Princess against Fenrir, as she was forced to declare her retirement. In True Volume 1, Rias' Peerage helped in the subjugation of the unknown Devils where they encountered Ingvild Leviathan. After hearing her circumstances and taking her to the beach, where they were attacked by Nyx. The Peerage along with Issei's peerage fought Nyx and her army of artificial devils, which they defeated. In True Volume 2, Team Rias Gremory had a Rating Game match against Issei's Team Red Dragon Emperor of the Blazing Truth. Despite initially gaining the advantage by using a suprise attack, which allowed the to eliminate Bova Tannin and Roygun Belphegor, the team lost after Rias was defeated by Issei. After that she and her peerage excluding Lint Sellzen, Vasco Strada, and Crom Cruach joined Issei's Team as backup members. In True Volume 3, members of the peerage accompanied the second years to their field trip to Kyoto, as Issei and the rest of Occult Research Club had to star in a Oppai Dragon event that was planned. During their sightseeing, they were attacked by Gressil and Sonneillon. After the two retreated, the peerage learned about Erebus' plot in Kyoto as they joined forced with Issei's peerage, the Slash/Dog team and Hero Faction to stop it. In True Volume 4, the peerage went to London to stop the Alliance of Hell for good and restore Issei to his normal self after he had his personality altered by Meredith Ordinton. In the aftermath, Rias traded her remaining Rook Piece, to Sona Sitri in exchange for Loup Garou, making him her second Rook. Type of Requests: The usual types of requests done by each member of Rias' peerage (including former) are: - Rias Gremory: Rias receives the least requests among her group due to the requirement that it has to be worthy of a High-class devil, such as herself. Therefore, her jobs include either removing curses from a cursed item, or defeating a certain monster because they are targeting a client. - Akeno Himejima: Akeno's usual clients are either the bosses of huge corporations or rich wives, where she does a wide range of work that mostly consists of her taking away the stress of people living in the high society, from listening to their daily worries to drinking tea with them. - Koneko Toujou: Koneko normally receives jobs ranging from being an opponent at playing cards to wearing a cosplay for a photo shoot. - Yuuto Kiba: Yuuto's requests usually come from older women and working women who consult their stress with him or by having Yuuto cook for them. - Issei Hyoudou: Issei commonly gets many weird requests from weird people. - Asia Argento: Like Koneko, Asia usually receives jobs ranging from being an opponent at playing cards to wearing a cosplay for a photo shoot. - Gasper Vladi: Gasper usually does his work from his computer where he interacts with people who are bad at interacting with others but have a wish that they want to be granted by a Devil. - Xenovia Quarta: Xenovia mostly receives jobs that involve physical work, such as helping out in construction work or being a practice partner for various sports. - Rossweisse: Rossweisse gets requests that are mainly from housewives where she does things like teaching them a way to make them lose their worries related to their finances and becoming their consultant. She also teaches them sure-fire methods to winning at bargain sales despite her young age.

Summary: This magic is the most commonly used magic among all factions and supernatural beings due to its utility. It allows the user to protect themselves and others. Abilities: This magic allows the user to create magic circles or barriers to protect themsleves and others from outside attacks. Whenever a user creates a defensive magic circle of barrier, they have to keep focus on maintaining it or else it'll shatter and pour their power into it in order for it not to crumble under the onslaught of powerful attacks. Depending on the skill of the user, Defensive Magic can be used to protect the user from a array of strong attacks, the barrier will be broken if it suffers from a continuous onslaught of attacks or a attack from a overwhelmingly powerful source can instantly destroy it. A skilled practioner such as Ladon who specializes in barriers was able to create one that kept his intended targets from using their powers, and he was able to create a barrier, which could distort spacetime.

Summary: A form of Teleportation Magic, Summoning Magic is generally used to call upon a supernatural being whenever someone requires help, these range from Magicians, Devils and even Familiars so long as they form a pact. Abilities: A summoning preformed by humans is done by preparing a ritual with rune writing and symbols depending on what they're trying to call. Beings who can use magic preform a summoning do so by simply casting a magic circle for their summoning to appear. In modern day, the ritual is now made on a sheet of flyer with the magic circle placed on it by the supernatural being. The flyers can also allow others to summon another's familiar.

can be utilized to summon a Dragon to a certain location. To do so, a ritual is required to be prepared and several other Dragons or Sacred Gear users that have a Dragon's soul sealed inside their Sacred Gear have to be present, at the bare minimum 3 Dragons have to be present to forcibly summon another Dragon. The more dragons there are and the stronger they are, the stronger Dragon they can summon. To summon a powerful Dragon God like Great Red would require multiple if not all of the Dragon Kings. Individuals who make a Familiar pact with a Dragon can utilize Dragon Gate magic to summon it. While initially only Dragons can utilize Dragon Gates to summon other Dragons, it is possible for others to use other methods to summon Dragons. Using the Nine-Tailed Fox along with Kyoto's leylines would allow someone to achieve a similar effect.

Monsters and supernatural beings in High School DxD who have been magically bound to a Devil as a servant or ally. Abilities: Familiars are considered a basic requirement for Devils. They could assist their masters in various tasks, be used for information gathering and relaying messages, as well as perform any other odd jobs that their masters could think of. Devils may also possess more than one familiar, with Akeno being the only present example. Familiars are shown to have different abilities depending on their species. For example, Asia's Dragon familiar acts as her personal bodyguard and Issei's familiar, Ryuuteimaru, acts as a mode of transportation. Devils may summon their familiars to them at any given time. Duties: There do not appear to be any specific duties that familiars are supposed to perform, though Rias has stated they can be used to bring information or carry messages. Mostly, they have been shown performing janitorial work and odd jobs for their masters.

Light Power (光の力, Hikari no Chikara) is the power primarily used by Angels and Fallen Angels in High School DxD. : Summary All Angels created by God of the Bible are able to manipulate the power of light, letting them create Light-based Weapons able to deal extra damage to creatures of darkness such as Devils, Vampires, and Youkai, being almost like a poison to them. Despite "falling" Fallen Angels maintain their Light Powers. There is an advanced application of using Light Powers employed by high-ranking Angels, who combines light and another element to produce a light-infused variant, such as Baraqiel, who fuses light and lightning to create Holy Lightning, and Uriel, who combines light and fire to create Holy Fire. Both of them are considered to have the highest amount of firepower among Angels, able to erase High-Class Devils and wound Ultimate-Class Devils in a single attack. This "fusion" can be inherited as Akeno Himejima, Baraqiel's daughter, inherited his power too. Since members of the Brave Saints are Reincarnated Angels, they can use the same Light Powers, with some having their own unique examples of use: Griselda can strengthen her fellow Angel's light using hers,[1] Jessica can use Light Powers to produce barriers,[2] and Ryuu, a Chinese martial artist who uses it as the core of his fighting style.[1] Light Powers can also be imbued into items such as Light Swords and Guns, which is often wielded by Exorcists in order to hunt creatures of darkness. Humans and Magicians can mimic the same Light Powers are Angels through either using Light Magic, or Sacred Gears, like Staring Blue and Staring Green or the True Longinus and Incinerate Anthem.
