Upon beginning her middle school journey, Akari Akaza joins the Amusement Club alongside friends from her childhood, Kyouko Toshinou and Yui Funami. Along with them, Chinatsu Yoshikawa, a fellow classmate, also joins the club after stumbling upon the disbandment of the Tea Club. The club operates in a former tea room with no set agenda, allowing the girls to participate in leisure activities at their own discretion.
