Toji Fushiguro

Toji Fushiguro, originally born into the prestigious Zenin clan as Toji Zenin, stands as one of the most consequential and formidable figures in Jujutsu Kaisen, known infamously as the "Sorcerer Killer" for his unparalleled ability to hunt jujutsu practitioners despite possessing absolutely no cursed energy. Defined by a Heavenly Restriction that completely eliminated his cursed energy in exchange for monstrous physical strength, lightning-fast speed, and heightened five senses that allow him to perceive curses and interact with the supernatural world through raw physicality alone, Toji became a pariah within his conservative family who valued cursed techniques above all else, leading him to leave the clan, take his wife's surname, and operate as a high-stakes mercenary. He compensates for his lack of magic with a cunning, tactical intellect and an arsenal of special grade cursed tools—most notably the Inverted Spear of Heaven, which forces the nullification of any cursed technique, and the Split Soul Katana—which he keeps hidden inside a tame, shrinkable cursed spirit wrapped around his torso to render himself invisible to magical detection. His narrative impact is monumental, particularly in the Hidden Inventory Arc where he masterminded the assassination of the Star Plasma Vessel, Riko Amanai, by wearing down Satoru Gojo over several days; he is the only man to ever defeat Gojo in combat, pushing the future "strongest sorcerer" to the brink of death and inadvertently causing Gojo’s awakening and mastery of Reverse Cursed Technique. Though he presents himself as a callous, gambling-addicted man who sold his own son, Megumi, to the Zenin clan, his motivations were layered with a twisted desire to protect Megumi from the discrimination he faced as a non-sorcerer, a complexity revealed in his final moments when he told the awakened Gojo about Megumi, effectively entrusting the boy’s future to him. Toji’s legacy persisted even after death, as he was temporarily resurrected during the Shibuya Incident where, acting as a puppet of pure carnage, he obliterated a Special Grade curse before regaining his sanity upon recognizing Megumi, choosing to commit suicide rather than harm his son, thereby cementing his status as a tragic, terrifying force of nature who broke the chains of fate and permanently altered the trajectory of the jujutsu world.
