The core traveling party typically consists of Lina Inverse, Gourry Gabriev, Zelgadis Greywords, and Amelia Wil Tesla Seyruun. Lina provides destructive magical power and leadership, Gourry offers reliable swordsmanship and loyalty, Zelgadis contributes knowledge, shamanistic magic, and cynicism, and Amelia supplies white magic support, combat assistance, and unwavering (if dramatic) moral drive. Their contrasting personalities create both effective teamwork and frequent comedy.

Lina Inverse is brilliant, extremely confident, short-tempered, greedy for treasure and gold, and obsessed with food. She is quick to anger when insulted (especially about her physique or abilities) but is also courageous, quick-thinking, and fundamentally heroic when the world is truly threatened. Her arrogance is backed up by genuine skill.

Beyond the Demon Barrier lies a wider world where the influence of the mazoku is weaker and Holy Magic functions more freely. Black magic becomes significantly less effective outside the barrier. Knowledge of the outer world is limited for most people living inside, and travel between the two sides is difficult.

Xellos is completely loyal to Greater Beast Zelas Metallium. While he frequently manipulates, teases, and withholds information from Lina’s party, his actions ultimately serve Zelas’s interests. He will follow her orders even when they conflict with temporary alliances or personal amusement.

Amelia Wil Tesla Seyruun combines white magic with hand-to-hand shamanistic combat. She often mixes physical strikes with magical effects and frequently shouts justice-themed attack names. While not as purely destructive as Lina, she is a capable and energetic fighter who prioritizes protecting others.

Zelgadis Greywords’s primary personal goal is to find a way to reverse his chimeric transformation and become fully human again. This quest drives much of his involvement with Lina’s group. He is willing to pursue dangerous knowledge, including information related to the Claire Bible, in hopes of finding a cure.

Gourry Gabriev is one of the most skilled pure swordsmen in the world. Even without relying on the Sword of Light’s special properties, his technique, speed, strength, and combat instincts are exceptional. When using the Sword of Light he becomes a major threat even to high-level magical opponents and lesser mazoku.

Death Fog is one of the four great Ma-ō created by the Lord of Nightmares and rules one of the parallel worlds. Like Chaotic Blue, almost no detailed information about Death Fog or its opposing Dragon God appears in the main series. It is mainly mentioned when discussing the broader cosmology of the four worlds.

Chaotic Blue is one of the four great Ma-ō created by the Lord of Nightmares and rules one of the parallel worlds. Very little detailed information about Chaotic Blue or its opposing Dragon God is given in the main Slayers series. It is primarily referenced in cosmological discussions alongside Ruby-Eye Shabranigdo, Dark Star, and Death Fog.

Airlord Valwin (Sky/Air Dragon King) and Earthlord Rangort (Earth Dragon King) are the remaining two aspects of Flare Dragon Ceiphied alongside Aqualord Ragradia and Flarelord Vrabazard. Together the four Dragon Lords were left behind to continue opposing the mazoku after Ceiphied sank into the Sea of Chaos.

Eris (full name Erisiel Vrumugun) was an assistant and subordinate of Rezo the Red Priest who was in love with him. After his death she sought revenge against those who defeated him and was involved in the events surrounding Copy Rezo and the destruction of Sairaag.

Lina Inverse and Gourry Gabriev form the core partnership. Gourry acts as Lina’s bodyguard and traveling companion. Their relationship is close and enduring, mixing bickering, mutual reliance, comedic misunderstandings, and genuine care. Romantic development is subtle and understated.

The Slayers series blends high-stakes fantasy adventure with strong comedy. Humor frequently comes from character personalities (Lina’s greed and temper, Gourry’s denseness, Amelia’s dramatic justice speeches, Xellos’s trolling), slapstick, exaggerated reactions, food-related gags, and light parody of traditional fantasy tropes. Serious and comedic moments often sit side by side.

Flarelord Vrabazard is one of the four aspects of Flare Dragon Ceiphied and represents the Fire Dragon King. The Golden Dragon priestess Filia Ul Copt serves under the Fire Dragon King’s temple. He is one of the remaining divine powers opposing the mazoku.

Aqualord Ragradia is one of the four aspects left behind by Flare Dragon Ceiphied and represents the Water Dragon King. He was defeated during the Kōma Sensō. His residual consciousness and knowledge persist in the form of the Claire Bible. He is one of the most significant Dragon Lords in the history of the Red World.

Gourry Gabriev is kind-hearted, loyal, and protective, but extremely dense and forgetful. He frequently fails to understand complex situations, forgets important details (including names or recent events), and takes things at face value. Despite this, he is a highly skilled and reliable swordsman who genuinely cares for his companions.

Lina Inverse is an 18-year-old young woman with bright red hair (often tied in a high ponytail or similar style), large golden/amber eyes, and a relatively petite build. She typically wears a distinctive outfit featuring a headband, cape, gloves, and practical traveling clothes suited for adventure. Despite her small stature she projects immense confidence and presence.

“That is a secret” (Japanese: “Sore wa himitsu desu”) is Xellos’s signature catchphrase. He uses it constantly to avoid giving straight answers, hide his true motives, and frustrate those around him. It is one of the most recognizable traits of his character.

Every mage has a limited magical capacity, sometimes referred to conceptually as a “bucket.” This determines how much magical energy they can safely channel. High-level spells require a large capacity. The Demon Blood Talismans temporarily expand this capacity dramatically, allowing Lina to cast extremely powerful spells with less personal strain.

Magical research and experimentation are common among ambitious mages. This includes the creation of new spells, chimeras, homunculi, magical items, and attempts to unlock forbidden knowledge such as that contained in the Claire Bible. Such research often leads to dangerous consequences, as seen with Rezo and other powerful sorcerers.

Inns, taverns, and restaurants are important social and practical locations in the Slayers world. They serve as places to rest, gather information, eat large meals, and recover between adventures. Lina and Gourry’s enormous appetites often make dining a memorable (and expensive) event at these establishments.

Bandit groups are common threats and targets throughout the lands. They frequently attack travelers and villages. Lina Inverse has built a strong reputation as the “Bandit Killer” by repeatedly locating, defeating, and looting such groups.

The royal family of Seyruun is deeply dedicated to the ideal of justice. Known members include King Philionel El Di Seyruun, his eldest daughter Gracia (Naga the Serpent), and his younger daughter Amelia Wil Tesla Seyruun. The family wields significant political and magical influence within the Holy Capital and values moral righteousness highly.

High-level black magic, especially spells like Dragon Slave, frequently causes massive collateral damage. Lina Inverse is particularly notorious for destroying large areas, enemy forces, and sometimes parts of the landscape as a side effect of her battles. This tendency contributes heavily to her reputation as the Empress of Destruction.

Most spells in the Slayers world require spoken incantations. The longer and more complex the chant, the more powerful the spell generally is. Skilled mages can sometimes shorten or accelerate chants through practice and talent. High-level spells such as Dragon Slave, Giga Slave, and Ragna Blade have distinctive, dramatic incantations that are widely recognized.

A homunculus is an artificially created human-like being produced through advanced magic and alchemy. Copy Rezo is the most notable example. Homunculi can sometimes develop free will and independent personalities, especially if experimental or imperfect methods are used in their creation.

Golems are magically animated constructs, typically made of stone or earth. They are durable and strong but usually lack true intelligence unless specially created. Zelgadis Greywords has golem components in his chimeric body, giving him stone-hard skin and enhanced physical resilience.

Mazoku feed on and draw strength from negative human emotions such as fear, despair, hatred, anger, and suffering. The more intense the negative emotions in an area, the more powerful and comfortable mazoku become. This is one reason they seek to create conflict, terror, and despair among humans.

Adventuring, treasure hunting, bandit killing, and mercenary work are common lifestyles in the Slayers world. Skilled mages and swordsmen can make a living by defeating monsters, criminals, and rival mages and claiming their valuables. This lifestyle is dangerous but offers freedom, wealth, and frequent encounters with both opportunity and world-threatening crises.

The common currency of the lands inside the Demon Barrier is gold coins and local coinage. Exact denominations are rarely emphasized. Wealth is often measured more practically by the ability to afford good food, inns, equipment, and magical items. Treasure taken from bandits is a frequent source of income for adventurers like Lina.

“Justice” is the core ideology of Amelia Wil Tesla Seyruun and the royal family of Seyruun. Amelia constantly declares her dedication to justice, often delivering long, dramatic speeches from elevated positions. In her view, justice means protecting the innocent, punishing evil, and upholding moral righteousness, sometimes to an exaggerated or comedic degree.

Food and large appetites are major recurring elements of daily life and comedy in the Slayers world. Both Lina Inverse and Gourry Gabriev are infamous for their enormous appetites and ability to consume vast quantities of food. Meals, eating contests, and the search for good restaurants frequently drive side plots and character interactions.

The Five Great Sages were legendary master mages of the past who achieved extraordinary levels of magical knowledge and power. Rezo the Red Priest is the most famous among them. They are regarded as historical benchmarks of human magical achievement.

A chimera is a magically created hybrid being composed of multiple different creatures or substances. Zelgadis Greywords is the most prominent example: one-third human, one-third golem, and one-third mazoku. Chimeras often possess enhanced physical durability and magical aptitude but suffer from identity issues and a desire to reverse the transformation.

The Astral Plane is the spiritual dimension where mazoku primarily exist. High-ranking mazoku are astral beings that project physical forms into the material world. Spells that directly attack the astral body (such as Ra Tilt or certain shamanistic spirit magic) are especially effective against them. Physical attacks and many conventional spells are far less effective against pure astral entities.

The Hellmaster’s Jar is a powerful magical artifact associated with Hellmaster Phibrizzo. It is capable of storing souls and was used in plots involving resurrection and the containment of dangerous spiritual entities, including aspects related to Rezo and Shabranigdo.

Zanaffar is a powerful ancient demon beast created in the distant past using incomplete knowledge from the Claire Bible. It was responsible for one of the early destructions of Sairaag. A warrior wielding the Sword of Light eventually defeated it. Later incidents involving Copy Rezo also reference or recreate similar chimeric threats linked to this legend.

Luke and Mileena are a pair of skilled mercenaries and treasure hunters. Luke is an arrogant but capable swordsman who can also use some magic, while Mileena is more reserved and cautious. They occasionally cross paths and work with Lina and Gourry.

“Empress of Destruction” is a title associated with Lina Inverse due to her tendency to cause massive collateral damage with high-level black magic, especially Dragon Slave. Entire landscapes, towns, or enemy forces have been devastated as a side effect of her battles, cementing this fearsome reputation.

“Bandit Killer” is one of the titles and reputations earned by Lina Inverse. She is infamous for hunting down groups of bandits, defeating them with overwhelming magical power, and taking their treasure. This reputation often precedes her and causes both fear and hostility from criminal groups.

Wizard Guilds and magical associations exist throughout the major cities of the continent, with particularly strong influence in Atlas City. These organizations regulate magical research, training, and political power among mages. Atlas City itself is governed in part by a council of powerful sorcerers and merchants, leading to frequent intrigue and power struggles.

Taforashia is a small kingdom whose people were placed in a suspended, frozen state due to the actions of Rezo the Red Priest. Reviving the people of Taforashia is the central goal of Pokota.

Volphied (also called Vorfeed or Night Dragon) is the supreme god (Shinzoku) of the Black World and the counterpart to Dark Star Dugradigdu. In that world the two eventually fused or Dark Star consumed him, resulting in the unstable destructive entity.

Dark Star Dugradigdu is the Ma-ō of the Black World and one of the four great Demon Lords created by the Lord of Nightmares. In his world he fused with or “devoured” his opposing god Volphied, becoming an uncontrollable force of destruction. He is the original creator of the five legendary weapons, including the Sword of Light.

The Spear of Light (Galveira / Galvayra) is an ancient weapon of immense power designed as a counterpart to the Sword of Light. It releases dense, piercing holy energy capable of shattering barriers erected by high-ranking mazoku and tearing through spiritual entities. It is one of the five legendary weapons created by Dark Star Dugradigdu.

The Sword of Darkness is the dark counterpart to the Sword of Light. It manifests a blade of pure void capable of absorbing incoming magical attacks and tearing rifts into the astral plane. It is far rarer and more dangerous than the Sword of Light.

“Zoamelgustar” is the dramatic and often nonsensical catchphrase frequently shouted by Martina Zoana Mel Navratilova. She uses it as a personal slogan or battle cry, usually in an exaggerated and comedic manner.

Frequently used mid-tier spells include: Flare Arrow / Fireball / Burst Flare: Fire shamanistic spells that launch arrows or exploding spheres of flame. Freeze Arrow / Howl Freeze: Ice/water shamanistic spells that fire freezing projectiles or create blizzards. Ray Wing: Wind shamanistic flight spell that allows the caster to fly. Elmekia Lance: Astral shamanistic spear of light effective against spiritual beings and mazoku. Ra Tilt: High-level astral shamanistic spell that attacks the target’s astral body; very strong against mazoku. Blast Bomb: Extremely powerful fire shamanistic explosion, among the strongest pure elemental spells. Dill Brand / Mega Brand: Earth shamanistic spells that violently upheave the ground. Recovery: Standard white magic healing spell. Lighting: Basic white magic spell that creates a floating ball of light. Flow Break: White magic that disrupts and cancels other spells in an area. These spells form the everyday toolkit of skilled mages alongside the higher-tier black and chaos magic.

The Flagoon is a massive sacred tree that once stood in the city of Sairaag. It purified the surrounding area of miasma and evil influence by absorbing it. The tree has been damaged or destroyed multiple times alongside the city itself during major magical disasters. It is closely tied to the history and repeated reconstructions of Sairaag.

Lei Magnus was an extremely powerful ancient sorcerer who became the host of one of the seven fragments of Ruby-Eye Shabranigdo. He is the original creator of the Demon Blood Talismans. The fragment within him awakened and played a key role in the events leading to the Kōma Sensō. He is one of the most significant historical human mages in the setting.

Holy Magic draws power directly from the Shinzoku (gods). It was largely unusable inside the Demon Barrier until after the defeat of Hellmaster Phibrizzo. It is rare and powerful, especially against mazoku. True Holy Magic is distinct from White Magic, though the two are sometimes confused by humans living inside the barrier.

White Magic focuses on healing, barriers, purification, and anti-undead or anti-mazoku effects. It draws on the caster’s own life force or residual holy power. It has limited direct offensive capability against living beings but is highly effective for support and against spiritual or undead threats. Key spells include Recovery, Resurrection, Flow Break, Holy Bless, and Lighting.

Shamanistic Magic manipulates the five elements: Fire, Water, Earth, Wind, and Spirit (Astral). It includes both physical elemental attacks and pure astral spells. Astral shamanistic magic is particularly effective against mazoku because they exist primarily on the astral plane. Common examples include Flare Arrow, Fireball, Freeze Arrow, Ray Wing, Elmekia Lance, and Ra Tilt. It is the most versatile category of magic.

Black Magic draws power directly from the mazoku. It is primarily used for pure destruction and is generally the most offensive form of magic. Higher-tier black magic spells require invoking the name or power of a specific mazoku. It is largely ineffective or weakened against mazoku of equal or higher rank unless the spell draws from a stronger source. Dragon Slave is the ultimate conventional black magic spell usable by humans.

Approximate power hierarchy from strongest to weakest: 1) Lord of Nightmares, 2) Fully awakened Ma-ō (Shabranigdo, Dark Star, etc.), 3) Five Lord Mazoku and the Four Dragon Lords, 4) Luna Inverse and Xellos (Luna is stated to be stronger), 5) High-ranking Golden Dragons and top human mages with strong amplification (such as Lina using the Demon Blood Talismans), 6) Elite human mages and warriors (Zelgadis, Gourry with the Sword of Light, Filia), 7) Average skilled mages and swordsmen, 8) Ordinary humans and low-level monsters. Specific matchups, preparation, and items can significantly alter outcomes.

Philionel El Di Seyruun is the ruler of the Kingdom of Seyruun and the father of Amelia and Naga (Gracia). He is an extremely muscular, justice-obsessed man who is surprisingly powerful in hand-to-hand combat. He shares his daughter Amelia’s dramatic flair for declaring justice and is a supportive, if overbearing, parent.

Zangulus is a skilled human swordsman who initially appears as a rival to Gourry Gabriev. He is proud, competitive, and highly competent with a blade. Over time he reforms and becomes a more positive figure. He is one of the stronger pure human swordsmen encountered by the main party.

Martina Zoana Mel Navratilova is the former princess (later queen) of the kingdom of Zoana. She begins as a comedic antagonist seeking revenge on Lina Inverse but eventually becomes an ally. She is overly dramatic, spoiled, and frequently uses the catchphrase “Zoamelgustar.”

The Kataart Mountains are a frozen, perpetually snow-covered northern mountain range. They serve as the absolute stronghold of Dynast Grausherra, one of the Five Lord Mazoku. The area is an incredibly dangerous wasteland teeming with icy monsters and high-ranking demons, and it is one of the key points of the Demon Barrier.

Dragon’s Peak is a treacherous, isolated mountain range that serves as the sacred sanctuary for the Golden Dragons. It is heavily guarded, fiercely isolationist, and functions as a major holy site. It contains ancient prophecies and knowledge related to the fate of the world and the conflict between shinzoku and mazoku.

The Philosopher’s Stone is a powerful magical amplifier capable of greatly boosting a mage’s power. Rezo the Red Priest sought it in an attempt to cure his blindness, which ultimately led to the awakening of the Shabranigdo fragment sealed within him.

Pokota (also known as Korba or the Prince of Taforashia) is a small creature capable of casting Dragon Slave. He seeks to revive the people of his kingdom, Taforashia, who were placed in a suspended state by Rezo’s actions.

Copy Rezo is a homunculus/chimera created by the original Rezo the Red Priest for experimentation. He developed free will and a sense of pride, seeking to surpass the original Rezo. He is responsible for one of the destructions of Sairaag.

Valgaav is a tragic ancient dragon warrior who was saved by Chaos Dragon Gaav after his race was slaughtered by the Golden Dragons. He was transformed into a mazoku-like being and served Gaav. He harbors a deep vendetta against both gods and demons, seeking to destroy the current world order and reset everything to zero.

Chaos Dragon Gaav is one of the original Five Lord Mazoku. Unlike the others he rebelled against the mazoku cause, became partially human, and sought his own path. He is deceased by the time of the main story. His actions and legacy play a major role through his former subordinate Valgaav.

Deep Sea Dolphin is one of the Five Lord Mazoku and the Sea Queen / Ruler of Water. She is one of the two female Demon Lords (alongside Zelas Metallium). Like most of the Five Lords she rarely appears directly and usually acts through subordinates. She helped raise the Demon Barrier after the Kōma Sensō.

Dynast Grausherra is one of the Five Lord Mazoku and the Ruler of Ice, War, and the North. His stronghold is the frozen Kataart Mountains. He is one of the Demon Lords who helped raise and maintain the Demon Barrier after the Kōma Sensō.

Golden Dragons are the highest-ranking dragon race that serves the Shinzoku (gods). They are isolationist and live primarily at Dragon’s Peak. They can take human form and possess powerful holy magic and physical strength. They harbor a deep, lasting hatred for mazoku—especially Xellos, who slaughtered thousands of them during the Kōma Sensō. Filia Ul Copt is a member of this race.

Atlas City is a bustling, highly political mercantile hub governed by a council of powerful sorcerers and merchants. It is a major center of commerce, magical research, and intense power struggles among its elite wizard guilds. Lina and Gourry first head there at the beginning of the series after their initial meeting.

The City of Sairaag is historically known as the Sacred City. It was famous for the massive Flagoon tree that purified the area and protected it from evil. The city has been destroyed and rebuilt multiple times due to devastating magical conflicts, including incidents involving Zanaffar, Copy Rezo, and Hellmaster Phibrizzo. It is the hometown of Sylphiel Nels Lahda.

The Kingdom of Seyruun (also spelled Saillune) is known as the Holy Capital. It is a peaceful nation governed by a deeply religious royal family dedicated to justice. The capital city is designed in the shape of a massive hexagram that naturally amplifies white and holy magic throughout its borders. It is the home of Amelia and (secretly) Naga.

Greater Beast Zelas Metallium (also called the Beast Queen) is one of the Five Lord Mazoku. She is the creator and master of Xellos. Unlike the other Demon Lords she created only a single servant (Xellos), pouring double the usual power into him. She rarely appears directly and usually acts through Xellos. She rules over beasts and shadows.

Hellmaster Phibrizzo is one of the Five Lord Mazoku and the Ruler of Souls/Death. He is considered the most powerful of the five. He often appears in the form of a young boy. He engineered the Kōma Sensō and later serves as a major antagonist, where he attempts to force Lina to cast an uncontrolled Giga Slave in order to destroy the world.

Rezo the Red Priest is a legendary blind healer and one of the Five Great Sages. He was famous for performing miracles and traveling the world helping people. Secretly he hosted a fragment of Ruby-Eye Shabranigdo and sought the Philosopher’s Stone in an attempt to cure his blindness. He is Zelgadis Greywords’ great-grandfather and the creator of Copy Rezo.

Luna Inverse is Lina Inverse’s older sister and the Knight of Ceiphied. She possesses a fragment of Flare Dragon Ceiphied’s will, making her one of the strongest beings in the world—stated by Word of God to be stronger than Xellos. Despite her immense power she prefers living a quiet life as a waitress in their hometown and rarely intervenes in world-threatening events. Lina is openly terrified of her.

Filia Ul Copt is a former priestess of the Fire Dragon King and a member of the Golden Dragon race. She can take human form and is usually extremely polite and refined. However, she has a fierce temper and harbors a deep racial hatred for mazoku, especially Xellos. When enraged she pulls out a massive mace hidden under her skirts and attacks with surprising violence.

Sylphiel Nels Lahda is a gentle, soft-spoken shrine maiden from the city of Sairaag. She is a master of white magic, including powerful healing and the rare Resurrection spell. She is deeply in love with Gourry Gabriev. Despite lacking high-tier combat magic, she is one of the few people besides Lina Inverse who can cast Dragon Slave. She is kind, polite, and often serves as a calming presence in the group.

The Kōma Sensō (Resurrection War or War of Demon Conquering) occurred approximately 1000–1013 years before the main story. Hellmaster Phibrizzo engineered the revival of one fragment of Ruby-Eye Shabranigdo (the Demon King of the North). The mazoku attacked Dragon’s Peak, defeated Aqualord Ragradia, and raised the Demon Barrier. During this war Xellos single-handedly slaughtered thousands of Golden Dragons, earning their lasting hatred.

The Demon Barrier (also called the Mazoku Barrier or god-sealing field) is a massive spiritual barrier raised by the remaining Demon Lords after the Kōma Sensō approximately 1000 years ago. It seals humans inside the main continent, blocks most Holy Magic, and greatly weakens the influence of the remaining Dragon Lords. Outside the barrier, black magic loses much of its effectiveness while holy and divine powers function more freely.

Flare Dragon Ceiphied (also spelled Ceifeed) is the supreme god (Shinzoku) of the Red World and the counterpart to Ruby-Eye Shabranigdo. After a long war he split Shabranigdo into seven fragments and sealed them in human souls, but the effort exhausted him. He sank into the Sea of Chaos, leaving behind four aspects: Aqualord Ragradia, Flarelord Vrabazard, Airlord Valwin, and Earthlord Rangort. A fragment of his will resides in Luna Inverse.

The Claire Bible is the residual consciousness and complete knowledge of Aqualord Ragradia (the Water Dragon King). It exists as a multidimensional collection of information, often appearing as stone tablets in a pocket dimension. It holds the absolute truth of the universe, deep magical secrets, and knowledge of the Lord of Nightmares. Multiple incomplete copies exist; the true original is extremely difficult to access and highly sought after by both humans and mazoku.

The Sword of Light (Gorun Nova) is a legendary heirloom of the Gabriev family wielded by Gourry. Its physical metal blade can be detached, allowing the hilt to generate a blade of pure, indestructible holy energy that slices through spells and deals massive damage to mazoku. It is one of the five legendary weapons originally created by Dark Star Dugradigdu.

The Demon Blood Talismans (also called Boost Talismans) are a set of four magical gems worn by Lina Inverse. They amplify the caster’s magical capacity by drawing on the power of the four Ma-ō of the four worlds. They were originally created by the legendary sorcerer Lei Magnus and later came into Xellos’s possession before he sold them to Lina. They also function as magical beacons that can be tracked by those familiar with their signature.

Ragna Blade (also called Laguna Blade) is a Chaos Magic spell that creates a blade of pure black void capable of cutting through space, dimensions, and the astral bodies of high-ranking mazoku. It heavily drains the caster’s life energy. Invented by Lina Inverse. Incantation: “Lord of the Darkness, shining like gold upon the sea of chaos... I call upon thee, celestial fragment! Void that steps forth, blade of frozen blackness! Synch with my power, synch with my body, and let us walk the path of destruction together! Deliver a strike that will shatter even the souls of the gods! RAGNA BLADE!”

Naga the Serpent (true name Gracia Ul Naga Seyruun) is Lina Inverse’s former traveling companion and self-proclaimed greatest rival. She is a voluptuous sorceress known for her booming, distinctive laugh and revealing armor. She specializes in ice and earth shamanistic magic. Secretly the eldest princess of Seyruun and Amelia’s older sister.

Amelia Wil Tesla Seyruun is the third princess of the Kingdom of Seyruun (also spelled Saillune). She is a hyperactive champion of “Justice” who loves delivering dramatic speeches from high places. She is highly skilled in white magic and hand-to-hand combat shamanism. Optimistic, stubborn, and idealistic, she frequently joins Lina’s party and prioritizes protecting the innocent and upholding justice above all else.

Zelgadis Greywords is a stoic sorcerer-swordsman who was transformed into a chimera (one-third human, one-third golem, one-third mazoku) by his great-grandfather Rezo the Red Priest. His skin is stone-hard and his hair is wire-like. He is an expert in shamanistic magic (especially astral spells) and swordsmanship. He desperately searches for a way to restore his fully human body and travels with Lina’s group largely out of convenience and shared goals.

Gourry Gabriev is a highly skilled and incredibly strong mercenary swordsman who acts as Lina Inverse’s bodyguard. He possesses the legendary Sword of Light. He has a heart of gold but is comically dim-witted and frequently forgets important details. Despite his denseness, he is loyal, kind, and one of the most formidable pure swordsmen in the world.

Lina Inverse is an 18-year-old genius sorceress known as the “Empress of Destruction” and “Bandit Killer.” She is short-tempered, fiercely greedy, obsessed with food and treasure, and extremely arrogant, yet fundamentally good-hearted and brilliant. She travels the world hunting bandits for their loot. She is the inventor of both Giga Slave and Ragna Blade and wears the Demon Blood Talismans. Her signature spell is Dragon Slave.

Giga Slave is an apocalyptic Chaos Magic spell invented by Lina Inverse that channels the power of the Lord of Nightmares. It can cut through any defense and destroy nearly any opponent, but risks destroying the entire world or universe if control is lost. Incantation: “Darker than black, darker than a starless night. King of Darkness, who shines like gold upon the Sea of Chaos, I call upon thee! I swear myself to thee! Let the fools who stand before us be destroyed by the power you and I possess! GIGA SLAVE!”

Dragon Slave is the ultimate conventional black magic spell that channels the power of Ruby-Eye Shabranigdo. It can obliterate entire cities or mountains in a single blast. It is Lina Inverse’s signature spell. Incantation: “Darkness beyond twilight, crimson beyond blood that flows. Buried in the stream of time is where your power grows. I pledge myself to conquer all the foes who stand before us, in accordance with the fools who choose to oppose us! DRAGON SLAVE!”

There are four main types of magic plus Chaos Magic. Black Magic draws power from mazoku and is highly destructive. Shamanistic Magic manipulates the five elements (Fire, Water, Earth, Wind, Spirit/Astral). White Magic focuses on healing, barriers, and purification. Holy Magic draws on the power of the gods (Shinzoku) but was largely unusable inside the Demon Barrier. Chaos Magic (Giga Slave and Ragna Blade) draws directly on the Lord of Nightmares and surpasses all other categories.

Xellos is the priest and general of Greater Beast Zelas Metallium. Because Zelas created only one servant and poured double the power into him, Xellos is the single most powerful mazoku beneath the Five Lords. He is a cunning trickster who hides his true intentions behind a polite smile and the phrase “That is a secret.” Extremely loyal to Zelas. Feared by Golden Dragons as the Dragon Slayer for slaughtering thousands of them during the Kōma Sensō.

The Five Lord Mazoku are the direct subordinates created by Ruby-Eye Shabranigdo. They maintain the Demon Barrier and rule the mazoku. They are: Hellmaster Phibrizzo (Ruler of Souls/Death), Greater Beast Zelas Metallium (Beast Queen), Deep Sea Dolphin (Sea Queen), Dynast Grausherra (Ruler of Ice/War), and Chaos Dragon Gaav (who rebelled, became partially human, and is deceased).

Ruby-Eye Shabranigdo is the Supreme Demon Lord (Ma-ō) of the Red World. Long ago he was split into seven fragments by Flare Dragon Ceiphied and sealed inside human souls so that reincarnation would gradually erode him. When a fragment fully awakens it possesses immense, world-threatening power. One fragment was sealed in the sorcerer Lei Magnus and later in Rezo the Red Priest.

The Lord of Nightmares created at least four parallel worlds resting upon the Sea of Chaos. Each world has its own supreme god (Shinzoku) and supreme demon (Ma-ō). The world of Slayers is the Red World. The other known worlds are linked to Dark Star Dugradigdu (Black World), Chaotic Blue, and Death Fog. If the mazoku fully win on a world, that world is destroyed and returned to the Sea of Chaos.

The Lord of Nightmares is the ultimate creator and the Sea of Chaos itself. Also called the Mother of All Things, the Golden Lord, or “He Who Shines Like Gold upon the Sea of Chaos.” Neither good nor evil; pure chaos. She created the four worlds and the opposing forces of gods and demons. Spells that draw directly on her power (Giga Slave and Ragna Blade) are the most dangerous in existence and can destroy the world if miscast. She has no fixed form or gender.
