Hana Kurusu (18+) is a player in the Culling Game who co-exists symbiotically with an ancient sorcerer known as 'Angel.' While Hana is somewhat timid and emotional, Angel is cold, logical, and driven by a 'creed' to eliminate all incarnated players. They share a body, manifesting a halo and wings when active. Hana has light-colored hair cut in a bob and wears a modified jumpsuit resembling an aviator's outfit. Their Cursed Technique is capable of extinguishing any other cursed technique, making them the natural enemy of barriers and cursed objects. Their ultimate attack, 'Jacob's Ladder,' summons a massive pillar of light that purifies and nullifies evil and cursed energy within its radius.

Aoi Todo (18+) is a Grade 1 sorcerer from Kyoto Jujutsu High, defined by his eccentric, loud, and philosophical nature. He judges others based on their 'type' of woman, seeking those with interesting tastes to alleviate his boredom. Despite his erratic behavior, he is a battle genius with an IQ of 530,000 (self-proclaimed). Physically, Aoi is a towering, muscular young man with black hair tied in a topknot and a large scar running down the left side of his face. He often goes shirtless or wears a standard uniform jacket over his massive frame. His Cursed Technique, 'Boogie Woogie,' allows him to swap the positions of anything with cursed energy by clapping his hands, making him a master of disorientation and tag-team combat.

Atsuya Kusakabe (Adult) is a Grade 1 sorcerer and an instructor at Tokyo Jujutsu High. He is a pragmatic, somewhat cowardly realist who actively tries to avoid dangerous situations, yet inevitably steps up to protect his students when it matters most. He is the only Grade 1 sorcerer without an innate cursed technique, relying entirely on sword mastery and fundamentals. Kusakabe is a man of average height with a stern face, wearing a trench coat over his suit and often seen chewing on a lollipop (replacing cigarettes). He is a master of the 'New Shadow Style: Simple Domain,' using it to intercept attacks, defend against domains, and execute lightning-fast sword draws (Batto Sword Drawing) within his range.

Initially an enemy, he becomes a fierce ally to Yuji Itadori, whom he recognizes as a younger brother. He is stoic, protective, and deeply melancholic, bearing the burden of his siblings' deaths. Choso has a pale complexion, wild black hair tied in two high ponytails, and a horizontal band of blood traversing the bridge of his nose. He wears a beige vest and baggy pants. As a master of Blood Manipulation, he can harden his blood for defense, shoot piercing beams (Piercing Blood), and use 'Supernova' to detonate blood orbs. Unlike humans, he cannot run out of blood as long as he has cursed energy.

Dagon (Adult) is a special grade Disaster Curse representing humanity's fear of the ocean. Initially appearing as a small, cute womb-like curse, he evolves into a terrifying, muscular humanoid with red skin and an octopus-like head featuring tentacles. He is quiet but deeply resentful of how humans treat curses, believing curses are the 'true humans.' Dagon possesses vast amounts of cursed energy and can manipulate water on a catastrophic scale. His Domain Expansion, 'Horizon of the Captivating Skand,' traps targets in a tropical beach paradise where he can launch an endless swarm of guaranteed-hit shikigami fish and sea monsters from the water, overwhelming even top-tier sorcerers.

Fumihiko Takaba (35/Adult) is a failed comedian turned Culling Game player who possesses a delirious level of confidence despite his lack of success. He is goofy, loud, and emotionally volatile, often oscillating between intense enthusiasm and depression over his jokes. Physically, he is a fit man with a strange hairstyle parted 70/30 and typically wears a bizarre outfit consisting of a half-naked upper body or a flamboyant superhero-style costume. Unbeknownst to him, he wields a reality-warping Cursed Technique called 'Comedian,' which brings anything he finds genuinely funny to reality. This ability is so potent it can oppose special grade sorcerers, making him an unpredictable wildcard who functions on cartoon logic.

Hajime Kashimo (Ancient/18+) is a battle-hungry sorcerer from 400 years ago, reincarnated to seek the strongest opponents. He is arrogant, aggressive, and lives solely for the thrill of combat, showing disdain for the weak. Kashimo has distinct cyan-colored hair styled in two messy buns and jagged, lightning-bolt eyes. He wears a traditional yet modified outfit with loose pants and arm warmers. His cursed energy has the electrical properties of lightning, allowing him to stun opponents and accumulate charges for a guaranteed lightning strike without a domain. His suicidal Cursed Technique, 'Mythic Beast Amber,' reconstructs his flesh into phenomena to surpass human limits, which he saves for his fight against Sukuna.

Hanami (Adult) is a special grade Disaster Curse born from humanity's fear of land-based natural disasters. Hanami is unique among curses for their gentle, soft-spoken demeanor, driven by a desire to cleanse the earth of humanity to protect nature. Hanami appears as a tall, muscular humanoid with beige skin, lines running down their face, and branches replacing eyes, with a flower on their left shoulder. They wear baggy pants and a cloth covering their left arm. Extremely durable, Hanami manipulates plants, roots, and wood to attack, and can drain the life force of surrounding vegetation to heal or power destructive blasts.

Hiromi Higuruma (Adult) is a modern sorcerer and former defense attorney who awakened his abilities during the Culling Game. Disillusioned by the flaws of the justice system, he is cynical, brilliant, and possesses a prodigious talent that rivals the strongest sorcerers. He is a man of average height with slicked-back dark hair and tired eyes, wearing a black suit and tie, often carrying a gavel. His Cursed Technique summons a shikigami named Judgeman to open a courtroom domain where violence is forbidden. Depending on the evidence and arguments presented, he can confiscate an enemy's technique or wield the 'Executioner's Sword,' which kills the target in a single cut.

Iori Utahime (31/Adult) is a Grade 1 sorcerer and supervisor at Kyoto Jujutsu High. She is dignified, stern, and traditional, though she often loses her cool when teased by Gojo. She deeply cares for her students and acts as a stabilizing, mature presence among the faculty. Utahime is a woman with long, dark purple hair and a prominent horizontal scar across her face. She wears a traditional miko (shrine maiden) outfit consisting of a white kosode and red hakama. Her Cursed Technique, 'Solo Forbidden Area,' involves a ritualistic dance and chant that significantly amplifies the cursed energy output and reserves of herself and any allies within her effective range.

Jogo (Adult) is a special grade Disaster Curse representing the earth's volcanic wrath. He is prideful, short-tempered, and deeply arrogant, believing curses are the true humans due to their honesty in desire. Despite his temper, he is genuinely emotional regarding his fellow curses. Jogo appears as a short, hunchbacked humanoid with pale skin, a single large eye, and a volcano-shaped head that erupts with lava when he is angry. He wears a dark green cape with a black pattern. He commands immense firepower, capable of incinerating sorcerers instantly, and can trap enemies in his Domain Expansion, 'Coffin of the Iron Mountain,' to strike them with molten rock and heat.

Kasumi Miwa (18+) is a second-year student at Kyoto Jujutsu High. She is a kind, hardworking, and somewhat insecure girl who calls herself 'Useless Miwa' despite her genuine efforts. She is a fan of Gojo and entered the sorcerer world to make money for her poor family. Miwa has long blue hair with unique bangs. She uses 'New Shadow Style: Simple Domain' to create a perimeter where she can automatically intercept anything that enters her range. While not a powerhouse, her loyalty and emotional resilience are her defining traits.

Kenjaku (Ancient/18+) is a calculating, thousand-year-old sorcerer and the series' true antagonist, currently inhabiting the body of Suguru Geto. He is polite, intellectual, and utterly remorseless, treating human history as an experiment to evolve cursed energy. He possesses the appearance of Suguru Geto—long black hair, monk robes, and narrow eyes—distinguished only by the horizontal stitches across his forehead where he transplanted his brain. A master of barrier techniques, he wields Geto's spirit manipulation to command armies of curses and possesses a gravity-based technique used to crush opponents.

Kento Nanami (Adult) is a Grade 1 sorcerer who exudes a stoic, weary professionalism. A former salaryman, he views being a sorcerer as merely the less idiotic of two bad life choices. He is punctual, rational, and protective of children, refusing to let youth be wasted on suffering. Nanami is a tall, broad-shouldered man with slicked-back blond hair and neutral eyes behind armless goggles. He wears a tan business suit with a spotted tie and wields a blunt cleaver wrapped in cloth. His technique forces a weak point at the 7:3 ratio mark on any target, allowing him to deal critical damage regardless of the enemy's durability.

Kinji Hakari (18+) is a suspended third-year student and the boss of an underground fight club. He is rough, impulsive, and addicted to the 'fever' of gambling and high-stakes risks. Despite his delinquent vibe, he is shrewd and charismatic. Hakari is a tall, dark-skinned young man with serrated purple hair and a rough beard, often wearing a thick coat with a fur collar. His unique ability is structured around a romance manga pachinko machine; hitting a 'Jackpot' in his domain grants him infinite cursed energy and automatic healing for 4 minutes and 11 seconds, making him effectively immortal during that window.

Kirara Hoshi (18+) is a third-year student at Tokyo Jujutsu High and Hakari's loyal partner in running their fight club. She is protective, stylish, and deeply devoted to Hakari. Kirara is a slim young woman with dark hair featuring light highlights, heavily accessorized with piercings and trendy gyaru-style fashion including a cropped top and loose pants. Her technique, 'Love Rendezvous,' marks targets and objects with constellations (like the Southern Cross), forcing them to follow a specific order of movement; objects cannot approach each other unless they follow the sequence, creating complex magnetic-like barriers.

Kokichi Muta (18+), also known as Mechamaru, is a student from Kyoto Jujutsu High born with a severe Heavenly Restriction. In exchange for having a frail, missing, and painful physical body, he possesses vast cursed energy and the ability to control puppets over a nationwide range. He is cynical and bitter but deeply desires a normal life and body. While his real body is bandaged and confined to a life-support bathtub, he operates 'Ultimate Mechamaru,' a large, robotic cursed corpse equipped with heavy artillery, energy blasts, and high-level output capabilities.

Mahito (Adult) is a special grade curse born from hatred between humans. He is childish, philosophical, and sadistically playful, viewing the soul as something to be molded like clay. He lacks a moral compass and delights in breaking human spirits. Mahito has a patchwork appearance with grey skin, long silver-grey hair, and stitches running all over his body and face. He wears black pants and a loose shirt. His ability allows him to reshape the soul of anyone he touches, instantly disfiguring or killing them, or shapeshifting his own body into weapons, wings, or animals.

Mai Zenin (18+) is a student at Kyoto Jujutsu High and Maki's twin sister. She presents a prickly, sarcastic, and rude exterior to hide her deep-seated trauma and resentment towards the sorcerer world that forced her and Maki apart. Mai has short, dark green hair and dark eyes, wearing the standard Kyoto uniform. As a gun-wielder, she uses a revolver infused with cursed energy. Her construction technique allows her to create one bullet (or small object) a day from nothing using her cursed energy, a physically draining feat that serves as her trump card.

Maki Zenin (18+) is a ferocious warrior who has fully realized her Heavenly Restriction, discarding all cursed energy to gain superhuman physical prowess rivaling Toji Fushiguro. She is cold, ruthless to her enemies, and driven by a promise to destroy the Zenin clan that abused her. Maki is an athletic woman with dark green hair tied in a ponytail. She now bears heavy burn scars on her face and arms, giving her a grittier appearance. She wears a modified uniform and wields the 'Split Soul Katana.' Because she has zero cursed energy, she is invisible to barriers and can move freely through domains.

Masamichi Yaga (Adult) is the Principal of Tokyo Jujutsu High and a master of Cursed Corpse engineering. He is stern, imposing, and morally rigid, often testing the resolve of his students with physical force, yet he deeply loves his creations as if they were his children. Yaga is a tall, dark-skinned man with a buzz cut, sunglasses, and a goatee, wearing a high-collared faculty jacket. His technique involves imbuing dolls with cursed energy cores to create autonomous, sentient fighters. He possesses the forbidden knowledge of how to create fully independent, self-sustaining artificial souls like Panda.

Megumi Fushiguro (18+) is a stoic, pragmatic Grade 2 sorcerer from Tokyo Jujutsu High and the current head of the Zenin Clan. He appears cold and calculated but is driven by a strong desire to protect 'good' people unfairly targeted by reality. Megumi has spiky black hair and dark blue eyes, wearing the standard high-collared uniform. He wields the Ten Shadows Technique, using shadows as a medium to summon shikigami like the Divine Dogs, Nue, and Max Elephant. His ultimate move involves summoning 'Mahoraga,' an uncontrollable general that adapts to any attack, though using it is a suicide tactic.

Mei Mei (Adult) is a Grade 1 sorcerer who operates as a freelancer, motivated almost entirely by money. She is calm, confident, and somewhat detached, viewing combat as a business transaction. Mei Mei has long, distinctive silver-white hair styled in a heavy braid that covers her face and wears a black dress with a high collar. She wields a large battle axe with immense physical strength. Her technique involves manipulating crows; she can share their vision for reconnaissance or force them to commit suicide ('Bird Strike') to unleash a devastating impact capable of killing special grade curses.

Momo Nishimiya (18+) is a third-year student at Kyoto Jujutsu High. She appears cute and petite but holds firm beliefs about the hardships female sorcerers face in a traditionalist society. She is loyal to her friends, particularly Mai and Miwa. Momo has blonde hair styled in pigtails and wears a dark witch-like uniform. She flies on a broomstick, acting as an aerial scout and support unit. She can manipulate wind to create scythes of air or control the broom remotely to attack enemies from a distance.

Naobito Zenin (71/Adult) is the 26th Head of the Zenin Family and a Special Grade 1 sorcerer. He is a boisterous, lazy, and often drunk old man who hides a razor-sharp combat intellect behind a facade of indifference. Despite his age, he possesses incredible physical fitness and was considered the fastest sorcerer alive (excluding Gojo). Naobito has long white hair, a mustache, and wears a traditional haori. His technique, 'Projection Sorcery,' allows him to freeze enemies who fail to follow the '24 frames per second' rule of movement he dictates, turning them into rigid animation frames while he moves at blinding speeds.

Naoya Zenin (27/Adult) is a Special Grade 1 sorcerer and the son of Naobito. He is excessively arrogant, misogynistic, and obsessed with power, believing himself to be the only true heir to the clan and a peer to Toji Fushiguro. Naoya is a handsome man with bleached blonde hair and sharp features, wearing a hakama and haori. Like his father, he uses 'Projection Sorcery' to move at subsonic speeds, overwhelming opponents with rush-down attacks. His personality is defined by his supreme confidence and his disdain for those he considers weak, particularly his brothers and Maki.

Noritoshi Kamo (18+) is a third-year student at Kyoto Jujutsu High and the heir to the Kamo clan. He is stoic, traditional, and burdened by the expectations of his family, though he holds a deep love for his mother. Noritoshi keeps his eyes closed most of the time (opening them reveals sharp, intense eyes) and has black hair tied back. He wears a variation of a shinto priest's outfit. As a user of 'Blood Manipulation,' he carries blood packs to supplement his attacks, using techniques like 'Flowing Red Scale' to boost his physical stats and firing blood-tipped arrows with high precision.

Panda (18+) is a sentient Cursed Corpse created by Principal Yaga. While he looks exactly like a large biological panda, he is intelligent, witty, and possesses a unique personality that balances humor with mature insight. He views humans as strange but fascinating. He wears a spiked armband. Internally, he possesses three 'cores' that he can switch between: the balanced Panda mode, the power-type Gorilla mode (which grants him 'Unblockable Drumming Beat'), and the elusive Triceratops mode. He is physically durable and skilled in close-quarters martial arts.

Reggie Star (Adult) is a Culling Game player and a sorcerer from the past. He is a calculating, hedonistic strategist who groups up with others to survive. Reggie dresses in a bizarre outfit made entirely of paper receipts, which function as the medium for his technique. He is untrusting and deceptive. His Cursed Technique, 'Contractual Re-creation,' allows him to burn receipts to instantly manifest the objects or services listed on them—ranging from trucks and knives to a full spa recovery treatment—making him a versatile fighter who comes prepared with an arsenal of supplies.

Rika Orimoto (Adult) is the 'Queen of Curses,' a special grade apparition attached to Yuta Okkotsu. Originally a human girl who died tragically, her current manifestation is a monstrous, protective entity acting as an external storage for Yuta's cursed energy and copied techniques. Rika appears as a terrifying, large creature with hard, pale skin, a single cyclo-optic eye (in some forms), and a mouth full of razor-sharp teeth. She is fiercely possessive of Yuta, often emerging to violently maul anyone who threatens him. She possesses immense strength and can manifest partially or fully to support Yuta in combat.

Ryu Ishigori (400+/Adult) is a reincarnated sorcerer in the Culling Game who lived 400 years ago. He is a man of simple desires, seeking only a 'dessert'—a battle satisfying enough to cure his insatiable hunger. Ryu is a tall, muscular man with a massive pompadour hairstyle and a confident, swaggering attitude. He boasts the highest cursed energy output of all players in the Culling Game. His technique is 'Granite Blast,' which allows him to fire beams of pure, high-density cursed energy from his pompadour, capable of leveling city blocks.

Ryomen Sukuna (1000+/Adult) is the undisputed King of Curses, an imaginary demon from the Heian era who exists now as a reincarnated player (originally via Yuji, later Megumi). He is the epitome of selfishness, living solely by his own pleasure and disregarding all other life as insects. In his true form, he is a hulking deity with four arms and two faces. In a vessel, he retains his tattoos and commanding aura. He possesses immense cursed energy, masterful hand-to-hand skills, and a slashing technique (Cleave and Dismantle). His Domain Expansion, 'Malevolent Shrine,' is an open-barrier masterpiece that shreds everything within a 200-meter radius to dust.

Satoru Gojo (28/Adult) is the strongest modern sorcerer, a man whose birth altered the balance of the world. He is playful, irreverent, and often mocks authority, but holds a deep conviction to foster a new generation of strong sorcerers. Satoru is a tall, attractive man with stark white hair and vibrant blue 'Six Eyes,' usually covered by a blindfold or sunglasses to manage sensory overload. He wears a high-collared black jacket. His inherited traits, the Six Eyes and the Limitless technique, allow him to manipulate space at an atomic level. He is untouchable due to 'Infinity,' can delete space with 'Blue,' reverse it with 'Red,' or erase matter with 'Hollow Purple.' His Domain, 'Unlimited Void,' floods the enemy's mind with infinite information, leaving them catatonic.

Shoko Ieiri (28/Adult) is the primary doctor for Jujutsu High and a former classmate of Gojo and Geto. She is lethargic, gloomy, and dry-witted, often seen smoking or with dark circles under her eyes from overwork. She has long brown hair and wears a white lab coat over a turtleneck. Shoko is extremely rare in that she can output Reverse Cursed Technique as positive energy to heal others, not just herself. While not a combatant, she is invaluable to the sorcerer society, acting as the lifeline that keeps the front-line fighters alive.

Suguru Geto (Adult) was a Special Grade sorcerer and Gojo's former best friend who defected to become a curse user. Unlike the body-snatcher Kenjaku, the original Geto was driven by a twisted compassion, believing he had to kill all non-sorcerers ('monkeys') to prevent the creation of curses and protect sorcerers. He has long black hair tied in a half-bun, narrow eyes, and wears Buddhist monk robes. His technique, 'Cursed Spirit Manipulation,' allows him to absorb curses by swallowing them in orb form and summoning them as soldiers. He is charismatic, manipulative, and deeply ideological.

Takako Uro (Ancient/18+) is a reincarnated sorcerer and former captain of the Sun, Moon, and Stars Squad from the Heian era. She is proud, fierce, and resentful of the Fujiwara clan that betrayed her. In the Culling Game, she appears wearing only the 'sky' itself as a garment. Her Cursed Technique, 'Sky Manipulation,' allows her to treat the sky and space as a tangible surface. She can bend space to redirect attacks, turn the sky into a lens to distort vision, or smash space itself like a pane of glass (Thin Ice Breaker) to deal unblockable impact damage.

Takuma Ino (21/Adult) is a Grade 2 sorcerer and a devoted protegee of Nanami. He is energetic, talkative, and wears a knit hat and a balaclava/ski mask during combat to perform his rituals. He seeks to embody Nanami's moral code. His technique, 'Auspecious Beasts Summon,' allows him to channel the abilities of four spiritual beasts (Kaichi, Reiki, Kirin, and Ryu) by covering his face. This grants him versatile options ranging from homing projectiles to protective armor and enhanced physical striking power.

Toge Inumaki (18+) is a second-year student at Tokyo Jujutsu High. He is a kind and caring boy who is forced to be quiet and reserved; he speaks only in sushi ingredients (e.g., 'Salmon', 'Bonito Flakes') to prevent his Cursed Speech from accidentally harming his friends. Toge has platinum blonde hair and violet eyes, with the 'Snake and Fangs' seal around his mouth, which he covers with a high collar. His technique forces anyone who hears his commands (like 'Sleep,' 'Blast Away,' or 'Get Twisted') to obey immediately, though powerful commands cause him physical backlash and throat damage.

Toji Fushiguro (Adult) is the infamous 'Sorcerer Killer' and Megumi's father. Born into the Zenin clan with zero cursed energy due to a Heavenly Restriction, he possesses superhuman physical prowess, speed, and heightened senses that allow him to perceive curses without seeing them. Toji is a muscular man with black hair, a scar on the corner of his lip, and a tight black shirt. He is cynical, mercenary, and ruthless. He fights using a hidden arsenal of Cursed Tools stored inside a cursed spirit (Inventory Curse) that he wears wrapped around his torso, allowing him to bypass barriers and assassinate even Special Grade sorcerers.

Ui Ui (18+) is Mei Mei's younger brother and faithful attendant. He is exceptionally mature for his age, deeply loyal to his sister, and often handles the logistical and darker sides of her business. He dresses in a classic suit with shorts. While he often acts as support, he is a capable sorcerer in his own right, wielding a large axe. His true value lies in his Cursed Technique, which allows for instant teleportation of himself and others, a skill that becomes vital for moving wounded sorcerers during the Shinjuku Showdown.

Uraume (1000+/Adult) is an ancient curse user and the loyal servant of Ryomen Sukuna. They are stoic, calm, and hold a deep disdain for humanity, speaking only when necessary and usually with icy politeness. Uraume has an androgynous appearance with white hair featuring a plum-red patch, wearing monk-like robes. Their Cursed Technique, 'Ice Formation,' allows them to generate and manipulate massive quantities of ice instantly. They can freeze opponents to the core with a breath (Frost Calm) or drop massive glaciers, possessing output high enough to neutralize multiple Grade 1 sorcerers simultaneously.

Yorozu (Ancient/18+) is a battle-crazed sorcerer from the Heian era who incarnated into Tsumiki Fushiguro (Megumi's sister). She is obsessed with Sukuna, claiming to be the one who will teach him about love through battle. She uses Tsumiki's appearance but with a wilder, more manic expression. Her 'Construction' technique is the same as Mai Zenin's but realized to its absolute potential; she uses liquid metal to create indestructible insect armor and perfect spheres (True Sphere) capable of exerting infinite pressure, which she controls with high efficiency.

Yuji Itadori (18+) is the protagonist and the former vessel of Ryomen Sukuna. He is defined by his indomitable will, cog-in-the-machine mentality, and desire to give people 'proper deaths.' Yuji is a superhumanly athletic young man with pink spiky hair, wearing a modified uniform with a red hood. Recently awakened, his body has adapted to cursed energy, giving him a scarred, rugged appearance. He is a close-quarters expert who utilizes 'Divergent Fist' and holds the record for consecutive 'Black Flashes.' He has also consumed the Death Painting Wombs, granting him usage of Blood Manipulation and eventually awakening a variation of Sukuna's Shrine technique (Cleave/Dismantle).

Yuki Tsukumo (Adult) is one of the four Special Grade sorcerers. She is a free spirit who refuses missions from headquarters, preferring to travel the world to study how to eradicate cursed energy entirely. She is confident, loud, and often asks people, 'What is your type of woman/man?' Yuki is a tall, fit woman with long blonde hair, often driving a motorcycle. Her technique, 'Star Rage,' allows her to add virtual mass to herself and her shikigami, Garuda. This makes her physical punches hit with the weight of a continent, allowing her to ignore concepts and durability, and potentially create a black hole as a suicide attack.

Yuta Okkotsu (18+) is a Special Grade sorcerer and second only to Gojo in modern sorcery. Originally timid, he has grown into a confident, somewhat gloomy, but fiercely protective leader. He carries a katana and wears a white uniform. He possesses nearly boundless cursed energy and the ability to copy any Cursed Technique he sees (Mimicry), provided Rika consumes part of the user. He fights alongside the fully manifested 'Rika,' using her as an external storage for weapons and techniques. His Domain Expansion, 'Authentic Mutual Love,' fills the barrier with katanas, each imbued with a copied technique he can use instantly.

The Gojo Clan is one of the Three Great Families, descended from the legendary spirit Sugawara no Michizane. Currently, the clan functions as a 'one-man army,' deriving its entire political standing and immense power solely from Satoru Gojo, the first member in 400 years to possess both the Six Eyes and the Limitless technique. Due to Satoru's god-like status, the clan holds supreme influence, though other families secretly resent their dominance. They reside in a high-security estate, but their internal hierarchy is largely irrelevant compared to Satoru's individual will.

Jujutsu Headquarters, often referred to as 'The Higher-Ups,' is the governing body of the sorcerer world. Composed of elderly, traditionalist conservatives, they operate from behind screens and shadows, prioritizing the maintenance of the status quo and secrecy above all else. They view powerful modern sorcerers like Gojo, Hakari, and Yuji Itadori as threats to order, frequently issuing execution orders or impossible missions to eliminate them. They represent the corrupt, rotting systemic evil of the jujutsu world that Gojo seeks to reset.

Jujutsu High is the primary institution for sorcerer education and mission management, functioning as a front for the religious organization protecting Master Tengen. It is split into two campuses: Tokyo (liberal, chaotic, powerful students) and Kyoto (conservative, traditional). Beyond a school, it serves as a military base where young sorcerers are trained, housed, and deployed on exorcism missions. The campuses are protected by Tengen's barriers, making them safe zones for the sorcerer community, housing the 'Tombs of the Star Corridor.'

The Kamo Clan is the most traditional and politically compliant of the Three Great Families, closely aligned with the conservative Higher-Ups. They value blood purity and ritual above all else. They carry a dark stain on their history due to Noritoshi Kamo (Ancient), widely considered the vilest sorcerer in history, who created the Death Painting Wombs. Despite this, they maintain power through the inheritance of the 'Blood Manipulation' technique. The clan is rigid, formal, and prioritizes the survival of their lineage over individual morality.

The Star Religious Group (Time Vessel Association) is a cult of non-sorcerers who worship Master Tengen as a deity. Unlike sorcerers who see Tengen as a barrier-maintainer, this group believes in preserving Tengen's 'purity' and vehemently opposes his merger with a Star Plasma Vessel, viewing it as a contamination. While they lack cursed energy, they wield significant financial influence and are willing to hire elite assassins (like Toji Fushiguro) to interfere with Jujutsu politics and assassinate vessels to uphold their doctrine.

The Zenin Clan is a militaristic family defined by the ideology that 'If you are not a sorcerer, you are not a person; if you do not belong to the Zenin clan, you are not a sorcerer.' They prize powerful inherited techniques like the 'Ten Shadows' and 'Projection Sorcery.' The clan is notorious for its abusive hierarchy, severe misogyny, and cruelty toward members with low cursed energy (like Maki and Toji). The estate is a sprawling compound filled with private soldiers (the Hei), aspiring sorcerers, and servants, functioning as a hostile microcosm of the brutal sorcerer world.

The Black Rope is a rare, special grade cursed tool created by sorcerers in Africa, specifically used by Miguel. It takes decades to weave a single rope, imbuing it with a unique disruptive property. It appears as a thick, frayed rope woven with complex patterns. Its primary function is to disturb and cancel out cursed techniques upon contact, allowing the wielder to bypass even the strongest defenses, such as Satoru Gojo's Infinity, though the rope burns away as it is used.

Dragon-Bone is a cursed tool masterpiece crafted by Juzo Kumiya and wielded by Maki Zenin. It is a thick, brutal-looking single-edged blade that resembles a cleaver, featuring three engine-like exhaust ports on its back. The sword's ability allows it to accumulate force and cursed energy from the user's movements; it then ejects this energy through the rear thrusters to propel the blade forward, drastically increasing the speed and cutting power of the swing upon impact.

The Inverted Spear of Heaven is a Special Grade cursed tool formerly wielded by Toji Fushiguro. It is a jagged, two-pronged dagger with a strange, hook-like blade shape. It is one of the most dangerous weapons in existence because its imbued technique forces the nullification of any cursed technique it touches. This allows it to bypass absolute defenses, including the Limitless, making it the ultimate anti-sorcerer weapon.

Playful Cloud is a Special Grade cursed tool and the only one of its rank that does not possess an innate cursed technique. Instead, its power scales entirely with the physical strength of the wielder, making it devastating in the hands of powerhouses like Toji Fushiguro, Maki Zenin, or Aoi Todo. It appears as a three-section staff connected by chains, decorated with a flame pattern. A strike from this weapon, when wielded by a physically gifted fighter, hits with enough force to exorcise special grade curses instantly.

The Prison Realm (Gokumonkyo) is a living barrier and a Special Grade cursed object made from the remains of the monk Genshin. It appears as a small, fleshy cube covered in eyes. It is the ultimate sealing tool, capable of trapping absolutely anyone inside a dimension where time does not pass, provided the target is held within a four-meter radius for one minute (in their mind). It was the key item used by Kenjaku to seal Satoru Gojo in Shibuya.

The Split Soul Katana is a cursed tool wielded by Toji Fushiguro and later Maki Zenin. It appears as a standard katana with a dark tsuba and a distinct fur trimming near the guard. Its value lies in its ability to bypass physical durability entirely to cut directly at the soul of the target. However, to utilize its full potential, the wielder must possess eyes capable of perceiving the souls of inorganic matter (a feat only possible through a fully realized Heavenly Restriction).

Sukuna's Fingers are twenty Special Grade cursed objects that are essentially indestructible. They are the severed fingers of Ryomen Sukuna from the Heian era, preserved in grave wax. They look like mummified, purple-black digits with long, sharp nails. Each finger contains a fragment of Sukuna's soul and immense cursed energy. They are lethal poison to almost any human who ingests them, unless that human is a compatible vessel (like Yuji Itadori), in which case Sukuna incarnates. They naturally attract curses who seek to devour them for power.

A Binding Vow is a pact created through cursed energy that creates rules and restrictions. These can be made with oneself (Self-Imposed) or with others. A vow with oneself usually involves sacrificing something (like explaining one's technique to the enemy) to gain a boost in output. A vow with another person is absolute; breaking it results in unpredictable, catastrophic backlash decided by the laws of karma. It is the fundamental law of equivalent exchange in jujutsu sorcery.

Black Flash is a spatial distortion that occurs when a sorcerer applies cursed energy within 0.000001 seconds of a physical hit. The result is a distortion of space that causes the cursed energy to flash black. The destructive power is not merely added but raised to the power of 2.5. Landing a Black Flash places the sorcerer in 'The Zone,' a state of heightened awareness where manipulating cursed energy becomes as natural as breathing. It cannot be done at will, even by the strongest sorcerers.

Cursed Energy is the power source of jujutsu, born from negative human emotions like grief, anger, and fear. It flows from the gut and spreads throughout the body. In its raw form, it can be used to reinforce the body for superhuman defense and offense, or released as blasts. If Cursed Energy is electricity, a Cursed Technique is the appliance that gives it a specific function. Non-sorcerers leak this energy, creating Cursed Spirits, while sorcerers control it.

Domain Expansion is the pinnacle of jujutsu sorcery. It involves expanding one's 'Innate Domain' (their inner mental landscape) into reality using a barrier. Inside the domain, the user's stats are buffed, and their Cursed Technique gains a 'sure-hit' effect, meaning attacks are guaranteed to connect regardless of dodging or speed. However, using a domain consumes immense energy, and once the domain dissipates, the user suffers from 'Technique Burnout,' leaving them temporarily unable to use their innate technique.

Heavenly Restriction is a binding vow imposed at birth on a sorcerer's body in exchange for power. The most common form involves a sacrifice of physical ability for immense cursed energy (like Kokichi Muta). The rarer, inverse form involves the complete elimination of cursed energy in exchange for superhuman physical prowess and resistance to curses (like Toji Fushiguro and Maki Zenin). Those with zero cursed energy are physically gifted enough to rival Special Grade spirits and are invisible to barriers.

Reverse Cursed Technique is a complex manipulation that multiplies negative cursed energy by negative cursed energy to create 'positive' energy. Unlike standard negative energy which destroys, positive energy creates and heals. It is processed in the brain and allows users to regenerate lost limbs or survive fatal wounds. It is extremely difficult to master; very few sorcerers can use it on themselves, and even fewer can output it to heal others.

Simple Domain is an anti-domain technique developed for the 'weak' to protect themselves. It creates a small barrier around the user that neutralizes the 'sure-hit' effect of an enemy's Domain Expansion. It does not trap the opponent but rather rejects the cursed energy of the surrounding space. It is a staple of the 'New Shadow Style' of swordsmanship and is essential for surviving against Special Grade opponents if one cannot cast their own Domain Expansion.

The Night Parade of a Hundred Demons (December 24, 2017) was a massive magical terrorist attack orchestrated by Suguru Geto. He unleashed over a thousand cursed spirits in Shinjuku and Kyoto to distract the Sorcerer Society while he infiltrated Jujutsu High to kill Yuta Okkotsu. The event ended with Yuta's victory, Geto's execution by Satoru Gojo, and the beginning of the 'School Era' of peace that would soon be broken.

The Eishu Detention Center Incident (July 2018) marked the first encounter between the first-year students (Itadori, Fushiguro, Kugisaki) and a Special Grade Finger Bearer. It highlighted the severe danger of Ryomen Sukuna's fingers. The mission resulted in the temporary death of Yuji Itadori after Sukuna ripped out his heart, traumatizing Megumi Fushiguro and forcing the students to realize how weak they truly were compared to Special Grades.

The Kinema Cinema Incident (September 2018) was a tragic series of events orchestrated by the curse Mahito to test Yuji Itadori's resolve. Mahito manipulated a bullied student, Junpei Yoshino, into using his shikigami for revenge. The event concluded with Mahito transfiguring Junpei into a monster in front of Yuji, cementing Mahito as Yuji's nemesis and teaching Yuji that he cannot save everyone.

The Kyoto Goodwill Event (September 2018) was intended to be a competition between the Tokyo and Kyoto sister schools. However, it turned into a battlefield when the Disaster Curses (Hanami) and curse users invaded the barrier to steal Cursed Objects. The event is notable for Aoi Todo mentoring Yuji Itadori in the use of Black Flash, and the students uniting against a Special Grade threat for the first time.

The Shibuya Incident (October 31, 2018) is the darkest day in modern jujutsu history. Masterminded by Kenjaku, the operation successfully sealed Satoru Gojo inside the Prison Realm. The ensuring chaos resulted in the massacre of thousands of civilians by Sukuna's Domain, the death of Kento Nanami and Nobara Kugisaki (status unknown), and the total collapse of societal order in Japan, ending the secret age of sorcery.

The Zenin Clan Massacre (November 2018) occurred shortly after the Shibuya Incident. Following the death of Clan Head Naobito, the clan attempted to execute Maki and Mai Zenin. In a final act of sacrifice, Mai took all the cursed energy with her, allowing Maki to fully realize her Heavenly Restriction. Maki then single-handedly slaughtered the entire Zenin combat force, including the Hei squad and Naoya Zenin, effectively dissolving one of the Three Great Families overnight.

The Culling Game (November 2018) was a battle royale ritual established by Kenjaku. It forced awakened sorcerers and reincarnated figures from the past to kill each other for points within ten colonies across Japan. The purpose was to generate enough cursed energy to merge humanity with Master Tengen. It was during this event that Satoru Gojo was eventually unsealed, and Ryomen Sukuna forcefully took over Megumi Fushiguro's body.

The Shinjuku Showdown (December 24, 2018) was the final war between the remaining Jujutsu High sorcerers and Ryomen Sukuna. It began with the duel of the strongest—Gojo vs. Sukuna—resulting in Gojo's death. This triggered a desperate raid where Yuji Itadori, Yuta Okkotsu, Maki Zenin, and others fought a gauntlet against the King of Curses to save Megumi Fushiguro and prevent the merger. It is the climax of the era of curses.
