Toji

Toji Fushiguro, the "Sorcerer Killer" from Jujutsu Kaisen, is a non-sorcerer from the Zenin clan born with a Heavenly Restriction, giving him immense physical power but no cursed energy, making him undetectable by sorcerers; he's a ruthless, mercenary assassin driven by hatred for the jujutsu world, yet showed kindness by leaving the Zenin clan, taking his wife's name, and caring for his son Megumi, until his wife's death led him back to his violent life and ultimately his fatal confrontation with Satoru Gojo. He's a tactical genius, using cursed tools like the Inverted Spear of Heaven and storing them in a cursed spirit inventory, and his fight with Gojo inadvertently led to Gojo's power-up
