He is a powerful mentor and teacher at Tokyo Jujutsu High, dedicated to protecting his students and reforming the corrupt leadership of the jujutsu world. He possesses both the Limitless technique (allowing him to manipulate space, create an absolute barrier, and telekinetically distort gravity) and the Six Eyes, which grant him flawless perception and virtually infinite energy efficiency. His ultimate technique is the domain expansion, Unlimited Void. He is highly confident, playful, and irreverent toward authority, but switches to a ruthless, unstoppable force when facing dangerous curses and enemies.

He was originally a student at Tokyo Jujutsu High and the best friend and classmate of Satoru Gojo. However, the psychological toll of his duties and witnessing the cruelty of ordinary humans pushed him to a breaking point. He defected from jujutsu society, massacred a village, and became a cult leader to amass power.Ideology: He possessed a severe hatred for non-sorcerers, whom he derogatory referred to as "monkeys". His ultimate goal was to eradicate all non-sorcerers to force humanity to evolve, creating a world where jujutsu sorcerers would no longer have to suffer or die protecting the weak. He was a master tactician and close-quarters combatant whose innate technique was Cursed Spirit Manipulation. This allowed him to swallow defeated curses to freely control and deploy them in battle, culminating in his ultimate attack, Maximum: Uzumaki.

Unlike human users of this technique, his hybrid biology allows him to convert cursed energy into blood, meaning he can fire lethal, pressurized blood attacks (like Piercing Blood and Supernova) without ever risking bleeding to death.

The Vessel: He has the rare capability to safely ingest the fingers of Ryomen Sukuna, functioning as a living cage for the King of Curses.Abilities: He possesses freakish natural physical strength, excels at landing devastating Black Flash critical hits, and eventually awakens his own cursed techniques.Drive: He fights selflessly, guided by his grandfather's final wish to protect people so they can experience a "proper death."

Goal: Instead of hunting individual curses, she travels globally to research how to eliminate the root cause of cursed energy entirely.Abilities: Her technique, Star Rage, adds crushing, virtual mass to herself and her shikigami beast, allowing her to deliver devastating physical strikes that ignore standard durability.Stance: Fiercely independent and carefree, she openly defies the higher-ups and refuses to take assignments from Jujutsu High to focus purely on her own goals.

Background: A former corporate salaryman, he returned to the brutal world of sorcery because he wanted his daily work to directly save lives.Abilities: His Ratio Technique enforces a 7:3 mathematical split on targets to create an artificial weak point, while his Overtime binding vow increases his power once the clock runs past standard working hours.Core Drive: Stoic and professional, he works under a strict moral code to act as a shield for young students, keeping them from bearing the weight of adult responsibilities too early.
