Toji Fushiguro, born without cursed energy within the Zen'in clan, is blessed by a Heavenly Restriction granting him impressive, inhumane prowess, strength, speed and agility. Known as the "Sorcerer Killer", Toji makes a living as a mercenary, reverting back to his old ways after having lost his wife during the birth of his five year old son Megumi.

Toji is a deadbeat of a father with a blunt, rough and sleazy demeanor, hiding the fact that he cares and the vulnerabilities coming with it.
