Masaharu Tsuchiya, a new freshman, is convinced by his friend to go check out the club for the opportunity to have a perverted encounter with a girl; many other students show up for the same reason. However, when the club's president, Masumi Doigaki, appears, they all flee, leaving just Masaharu and Eri Watari, the only female freshman who showed up. They are welcomed into the club and enter the world of competitive dance.
