Born December 7, 1989, into the prestigious Gojo clan, Satoru Gojo inherited both the Limitless technique and the rare Six Eyes for the first time in roughly four hundred years. The Six Eyes granted him extraordinary perception, heightened ability to see and manipulate cursed energy, and immense brain processing power. His birth shifted the jujutsu world's balance of power, earning him a bounty exceeding a hundred million. Bounty hunters remained powerless against him, even in his youth. An early encounter with Toji Zenin, who possessed zero cursed energy due to Heavenly Restriction, marked the sole instance anyone detected Toji's presence while standing behind them; Gojo turned to look directly at him during surveillance. As a second-year student at Tokyo Jujutsu High, Gojo worked alongside classmates Suguru Geto and Shoko Ieiri. During a mission to escort the Star Plasma Vessel, Riko Amanai, for merging with Tengen, they faced attacks from groups Q and the Time Vessel Association. After bonding with Riko and accommodating her request to visit Okinawa, they were ambushed upon returning to Tokyo by the sorcerer killer Toji Fushiguro. Toji exploited Gojo's momentary distraction concerning Riko's safety, stabbing him through the neck with the Inverted Spear of Heaven and delivering fatal slashes. On the verge of death, Gojo awakened the reverse cursed technique, healing his injuries completely. He confronted Toji at the Star Religious Group's headquarters, killing him with Hollow Technique: Purple before retrieving Riko's corpse. When Geto arrived, Gojo suggested massacring the cult members clapping over Riko's death, but Geto dissuaded him. This event profoundly impacted both; Gojo's arrogance grew after perfecting his abilities, while Geto began questioning the morality of protecting non-sorcerers. Approximately a year later, Geto massacred a village and killed his own parents, declaring his intent to exterminate all non-sorcerers. Gojo confronted him in Shinjuku, where Geto questioned the connection between strength and identity. Though Gojo considered killing his best friend to prevent further calamity, he could not do it, allowing Geto to leave. This failure haunted Gojo, contributing to his later downfall. He later took responsibility for Megumi Fushiguro, paying utility bills for Megumi and his sister Tsumiki after their mother's money ran out and occasionally bringing Megumi on missions. During one mission, Megumi rescued Hana Kurusu, with Gojo teasing him about her potential romantic interest. As a teacher, Gojo sought to reform the jujutsu world by fostering a new generation of sorcerers. He intervened to save Yuta Okkotsu, a cursed teenager bound to the special-grade spirit Rika Orimoto, from execution by the jujutsu higher-ups. Convincing them to postpone Yuta's sentence, Gojo brought him to Tokyo Jujutsu High and mentored him alongside classmates Maki Zenin, Panda, and Toge Inumaki. He similarly protected Yuji Itadori after Yuji became the vessel for Sukuna, the King of Curses, by proposing Yuji consume all Sukuna's fingers before execution. This strategic delay allowed Gojo to train Yuji, believing he could reach his level of strength. Gojo's influence over the higher-ups stemmed from their fear of his power; he stated he could kill them all and overthrow the system if desired, though he considered education a more sustainable path to change. Gojo's personality combines laidback playfulness toward students and allies with ruthless cruelty toward enemies and sorcerer executives. He exhibits extreme confidence in his abilities, frequently declaring himself the strongest sorcerer and referring to himself as "the honored one throughout heaven and earth." This arrogance emerged after his near-death experience against Toji, temporarily overshadowing his grief for Riko. During intense battles, he occasionally enters a manic state, prioritizing victory and destroying enemies over saving innocent lives if he deems sacrifices unavoidable, though he avoids causing lasting harm to non-combatants. Despite his aloof exterior, he harbors deep humanity, seen in his sorrow over Riko's death, horror at Geto's descent, and distress when Yuji appeared to die. His trauma over losing Geto directly contributed to his sealing during the Shibuya Incident. Widely recognized as the strongest modern sorcerer even among special grades, Gojo possesses immense cursed energy reserves and unparalleled efficiency in its usage due to his Six Eyes, allowing near-limitless stamina. His physical prowess includes mastery of hand-to-hand combat rivaling the millennia-old Kenjaku, immense strength demonstrated by ripping apart special-grade curses like Jogo and Hanami, blinding speed exceeding Naobito Zenin, and extraordinary endurance enabling survival of near-fatal injuries. His capabilities were feared by enemies; Kenjaku admitted he could not defeat Gojo in direct combat, while Sukuna acknowledged his strength during their duel. His techniques center on the Limitless, which manipulates space through cursed energy. Infinity creates an impermeable barrier by converging infinite space around him, automatically filtering threats based on mass, speed, and cursed energy. Cursed Technique Lapse: Blue generates attractive forces for implosions, gravitational pulls, or high-speed movement, while Cursed Technique Reversal: Red produces repulsive forces. Combining both creates Hollow Technique: Purple, an imaginary mass that erases matter in its path. His reverse cursed technique enables instantaneous regeneration, even healing brain damage or replenishing burnt-out techniques mid-battle. His Domain Expansion, Unlimited Void, floods targets with infinite information, immobilizing them. He also employs barrier techniques like Curtain and Falling Blossom Emotion to counter enemy domains. He can spam domain expansions multiple times in quick succession thanks to his reverse cursed technique efficiency, a feat impossible for most sorcerers. Key battles highlight his dominance. He effortlessly overpowered and killed Jogo, forced Hanami to flee with a single attack, and fended off multiple special-grade curses simultaneously before being sealed in the Prison Realm during the Shibuya Incident when Kenjaku exploited his emotional connection to Geto's body. After his release, he immediately challenged Sukuna in the Shinjuku Showdown. During this duel, he demonstrated superior hand-to-hand combat and domain techniques, repeatedly damaging Sukuna and temporarily knocking him unconscious with a Black Flash. He adapted his domain's barrier rules at incomprehensible speeds and fought Sukuna, Mahoraga, and Merged Beast Agito at once. Though ultimately defeated, his performance cemented his reputation. A previously unseen aspect of his youth involved a formal genpuku ceremony orchestrated by the Gojo clan as a political statement against rival families like the Zenin. This ritual, a condition for his enrollment at Jujutsu High, framed his "rebellion" as a calculated move by the clan rather than genuine personal freedom, emphasizing his lifelong entanglement with jujutsu politics and contributing to his isolation despite his strength. This context adds depth to his later focus on mentoring students to create the supportive community he lacked.
