Taro Sado is a high school student who goes about his daily existence with a significant secret: he's a masochist! Taro, encouraged by his cross-dressing closest buddy Tatsukichi Hayama, approaches the Second Voluntary Group for assistance with his condition, and eventually joins the club when they promise to "fix" him. However, it turns out that all of the club's members have significant problems. Mio Isurugi, the club's head, is a self-proclaimed deity who is terrified of cats, Arashiko Yuuno is terrified of males, and club adviser Michiru Onigawara is a sadist who likes having others cosplay.
