Aoi hears all the truth about Subaru coaching the basketball club and agrees with his situation. However, Aoi gets angry when she finds that he is compromised to help Airi learn to swim regardless of studying for his own tests and brings some friends of hers to challenge the girls to a match with their coach at stake. It does not take long for Subaru to realize that Aoi's true intentions are to test Tomoka and her friends' determination and help them improve instead.
