He is one of the "Four Devas of Darkness", also known as the "Seal of The-O". He is rumored to be the most evil of the Dark Army, and pretends to be loyal to them in order to gain control of them. During the previous battle, he discovered an ancient document called a prophecy in the treasure vault of the Dark Army's mansion, and knew that Nidaime Gundam Daishogun and Yami Koutei would kill each other, as well as Yami Koutei's secrets, so he aimed to kill Alex who was still a baby right after the war. Even after Zakuto retired, he pretended to be loyal to the Waka Zakuto, but he is an ambitious man who uses schemes and fights for his own gain. The Jigoku Jaakuho cannon, which can be used not only as a normal cannon but also as a flame cannon and a ray cannon, is a troublesome weapon for the Gundam Army.
