Hiroto becomes a replacement teacher at Shuuou private girls’ school, the leading school in Japan for young ladies. Within this school, there’s a special place run by the students for themselves, a place where the maidens of high society mingle. This is Cure Mate Club. The owner of the club, Erina, meets him and makes him dress up as a girl.
