Katagiri was created by a group of sorcerers in order to make the perfect fighter. However, not only were his powers vastly stronger than intended, he also was mentally unstable. When he gained consciousness, the first thing he did was torture, and kill the sorcerers that brought him to life. The best fighters in all of Kelad-Thor had been summoned to put him under captivity. He awaited there until the current war that Kelad-Thor has been fighting, he was released and added to a team of four as a leader. He is certainly one of the most powerful fighters in the world and least empathetic people in the world.
