He is a master of Doga-ryu spear and sword techniques who trained in Doga Village. He vowed to raise his late master's child well, and puts that first. Due to Jiaku's despicable scheme, his child was taken hostage, so he joined the Hyakki Yakou Shuu. During his time with the Hyakki Yakou Shuu, he became the heartless demon Psycho Doga and slashed away at the members of the Gundam Army. He fought with the resolve to go to hell himself, but when his child was rescued by Tallgeese, who hated Jiaku's methods, he became Saiga Gundam and fought against the Hyakki Yakou Shuu with the Gundam Army. His deadly Tendo technique is Kaiten Taiji Ranbu. He swings his Kabuto Saiga with blinding speed, slashing his opponents without giving them a chance to counterattack.
