Toji Fushiguro

Toji Fushiguro, originally named Toji Zenin, appears repeatedly in the Jujutsu Kaisen series. He had been employed by the Time Vessel Association, among other organizations, during his time as a non-curse user.

He was a former member of the Zenin family and the notorious killer known as the Sorcerer Killer. Toji is the main adversary of Gojo's Past Arc and works for the Star Religious Group.

Toji was one of the best fighters in the history of jujutsu even though he wasn't a curse user and lacked any natural skill for the art. Toji competed against the most deadly and skilled jujutsu practitioners this era had to offer, his intrinsic physical power much superior to all others in his path.

Toji's five senses were at their ultimate best as a result of his Heavenly Restriction, which prevented him from using cursed energy. With merely his enhanced senses, he was able to perceive curses and jujutsu and even developed a resistance to them.

Megumi's father is one of the only non-curse users among Jujutsu Kaisen's most powerful characters and a truly incredible fighter who should not be taken lightly. It's difficult to defeat a jujutsu sorcerer like Geto without considerable trouble. Going up against Gojo should be virtually impossible.

Toji Fushiguro's physical dominance and extensive knowledge of the sorcerer community are what make him so menacing. He was appropriately given the moniker Sorcerer Killer due to his bloodlust and capacity to defeat even the most powerful sorcerers. Even though a few sorcerers have since overtaken Toji, in his prime, he was virtually unbeatable.
