The only son of Zakuto, the leader of the Zaku Clan. He is an accomplished man, skilled in both the arts and martial arts, and rivals his father, Zakuto. He used to be a gentle man, but after he received an assassination sword from an unknown donor that was presented to him when he came of age, he became selfish, ruthless, and cruel. Someone whispered in his head, "Let's revive the evil heart of my father, who has been bathing in the lukewarm water of peace!", which eventually led to him putting his father into a state of suspended animation, seizing power and reviving the Dark Army. He used his army to prevent the Daishogun from fully awakening his power, and hindered the collection of the Ball of Light, but all of this was just a way for Zakuto's body to be used to revive the Yami Koutei.
