On her first day attending the all-girls Nanamori Middle School in Takaoka, Toyama Akaza Akari oversleeps, to be awakened by her one-year-senior childhood friends: the level-headed Funami Yui and the often self-centered Toshinou Kyouko. Planning on exciting club activities at school, Akari joins the club her older friends have set up.

In regard to what the club does, Kyouko explains: "We just hang out and do whatever we want!" This is not exactly what the helpful and energetic Akari had hoped for.
