The Amusement Club foursome — Akari, Yui, Kyouko, and Chinatsu — continue their lively activities at the all-girls Nanamori Private Middle School. The squabbles over the usage of the defunct tea ceremony club's premises as their club room have long since been resolved with the student council: Ayano, Chitose, Himawari, and Sakurako. This may in part have to do with Ayano's secret crush on Kyouko. As that may be, the girls have all become very good friends, energetically enjoying each school day.
