高溝 八輔

Hachisuke, otherwise known simply as Hachi, is one of Yuuma's close friends and hangs out with him and Jun Watarase constantly. He seems to be desperate for any affection from girls, as the closest chance he has at getting a girl is with his friend Jun, who, despite his feminine appearance, is in fact male. He is often very perverted as well.
