During their rest day, Mayu suggests to Ryota that they go on a double date upon learning of Yoshioka and Honoka's date. Ryota keeps a close watch over Yoshioka as Honoka and Mayu have fun. Yoshioka shows up to the training session the following day ready to battle. Meanwhile, Mayu asks Honoka to join her sumo club, but Honoka insists on staying with Kyoritsu. On the last day of the training camp, something unexpected happens while Ryota is walking Saki home.

Ryota trains hard for the tournament, with Honoka advising him. Natsuko and Arisa are deeply moved to see the team united. Honoka's graduation is approaching, and the thought of parting ways with Ryota saddens her. Meanwhile, she hears that Natsuko and Aoki are planning the first-ever co-ed tournament. She meets with the director and expresses her desire for Kyoritsu to join but is told that they would have to win a league tournament in order to do so. On the day of the tournament, Yuma fails to show up. Without any other choice, Ryota and the remaining members compete and go up against Shikokukan University.
