All good things must come to an end, as the saying goes. It applies to everyone, including the students of Asahigaoka school. After spending five or so years together, Komari Koshigaya graduates. Her sister, Natsumi, graduates the following year, leaving Hotaru Ichijou and Renge Miyauchi as the only two students left attending the school. The next year, two new students move to the countryside: AJ Smith and her little sister, Annabel. The two sisters are thrust into the world of Asahigaoka, going on everyday adventures with their new friends.
