After Tami joins the yosakoi club, the group manage to convince Yaya to join in name only, allowing the club to become official with Sally as their advisor. Later, the girls decide to attend a yosakoi festival being held in Shōnan as their first club activity. With some time until the performance, Yaya and Tami spend some time getting to know each other, with Tami explaining how Naru taught her it's more fun to spend time with others than by yourself. As the festival gets underway, with Masaru also taking part, the girls pay close attention to another middle school yosakoi team that Masaru had helped out, inspiring Naru and the others to aim for the Hanairo Festival.
