History
In the manga, there is nothing known about his history.

In the anime, however, Yō said Kōzuji was a succesful Taekwondo and a Mixed martial arts fighter. His nickname at that time was "The Ultimate Warrior". When he met an actress on a variety show and she wouldn't give him her e-mail, he lost his temper and attacked her. He was sentenced into Deadman Wonderland after that.
