Futaba and Hikari invite Ai to hang out with them as they go shopping for logbooks and swimsuits. Afterwards, the girls go to the beach, where Futaba tells Kino about all the things she has learned since meeting Hikari. Futaba expresses her concerns about whether she can become a suitable buddy for Hikari, though Hikari expresses that she's had times when she lost her way as well, saying that it is a chance to have more fun. Afterwards, Futaba finally manages to pass the pool course, allowing her to move on to the Open Diver course with everyone.
