Chaos is the most sadistic member of the Himitsu Kessha. Uranus, wanting a crave for power, placed Chaos as a guinea pig and turned him into a very insane killer. Although without psyche, he remained in the top four. Gaia was declared a traitor for holding the first Toshindaibukai for a mutiny purpose and Uranus sent Chaos to kill him in the middle of his fight with Eiji. Chaos failed greatly and the society he was part of collapsed. In the events of the fourth Toshindaibukai tournament, Genma, an evil magician took his Shield of Genbu and possibly killed him.
