Because of a traumatic incident in the past, Sado Tarou has turned into a masochist, deriving pleasure from when cute girls violently beat him up. He will never be able to normally love if he stays like this though and his friend Hayama Tatsukichi suggests to look for help. So to cure his condition, letting him confess his love to Shihori-hime, he visits the Second Voluntary Club, that supposedly fulfils the wishes of students. Arriving there he only finds Isurugi Mio, a deluded girl believing she is a goddess, and Yuuno Arashiko, the girl that unintentionally turned him into a masochist...
