Until this year, Ousai Academy was an all girls' school. Takatoshi Tsuda, one of the first boys to go to the now co-ed school, finds himself confronted with Shino Amakusa, the student council president, because his tie isn't tight enough. In a short amount of time, he meets Suzu Hagimura, the treasurer, and Aria Shichijou, the secretary, finding himself roped in as vice president. According to Shino, a male perspective will help them along. As Takatoshi is about to find out, the student council, and the students of Ousai, are very very strange.
