He is an Akugyo Choujin who poses as a Seigi Choujin and enrolls in the Hercules Factory after the destruction of the d.M.p Headquarters. He is a master of psychological warfare and is well-studied in Choujin Wrestling techniques and their weaknesses. He has long-standing relationship with Kevin Mask, having saved his life at one point during their d.M.p training days. After his loss to Mantaro, he disappears for a while, returning during the Demon Seed Arc as an Idol Choujin.
