He is a high school student of Prefectural Sanada North High School and a former president of its Chemistry Club. He claims to strive for learning but his behavior is generally unprecedented. He accidentally blew up the clubrooms of the Chemistry Club and the Film Research Club which results in the abolition of both. He then became close friends with the president of the Film Research Club and a member of the Computer Club. The three of them even attempted hitting on Ringo-chan. They also asked the Funky High School Girls out to karaoke once, and he is shown to be an acquaintance of Yanagi. It was then revealed that he was also a member of the Archdemon Punitive Force, and that the protrusion of his jaw is deliberate.
