The school festival is a roaring success! At the swim team’s live stage show, Umihara and Kawase perform with Mafuyu in a Full Pure costume for some reason. The audience cheers over Mafuyu’s well-defined dance moves. Then Uruka appears all clad in black, a style no one has seen her wear before!
 Nariyuki goes all over the school to drum up business for the udon noodle shop. After putting on an animal costume, he finds himself pursued by teachers. Asumi helps him escape to the gym, where the play Fumino is starring in is devolving into chaos!
