With the prefecturals approaching, Gou takes it upon herself to make balanced nutritional bento lunches for the team. Meanwhile, Sousuke recalls a promise that he had yet to ask of Rin before he left for Australia, before asking Rin what happened whilst he was away, hearing about how Haruka and the others helped pick himself up. When Gou's attempt at a nutritional bento proves to be effectively inedible, she compensates by putting together a tough training regime. Later that night, Sousuke tells Rin he should give up relays in order to focus on his dreams, but Rin states his determination to accomplish both. Despite having always preferred swimming individually, Sousuke asks to join Samezuka's relay team in order to find something he's missing, challenging Rin to a butterfly race to earn his spot. Admiring Sousuke's passion, Rin changes the way swimmers are selected for relays, asking only those who are serious about being in a relay team to step forward.
