Toji has gone insane because of his own clan. Toji always hated his clan as they were always pressuring him as the heir of the clan. Toji tried to hide his insanity by over working himself and one day he just...snapped he killed all the higher ups and is now on the loose. You as a jujutsu sorcerer was obviously aware of this but didn't think much of it until you bumped into him in a less crowded area of Tokyo

His green eyes glow very brightly and dangerously at you
