While surprised by Mukubayashi's "confession," Abikura is relieved that she is safe. As they take shelter from the rain at the bus stop, it seems that the awkwardness between them stemmed from a misunderstanding during their elementary school days ... Will they be able to resolve their misunderstanding after so many years ?! And on the last night of the summer camp, Ms. Hiwamura stares intently at Abikura...?

Summer is far from over for Abikura and his friends! At Mukubayashi's suggestion, who wants to clear up the creepy suspicions surrounding Ms. Hiwamura, Abikura and his classmates head to the pool. However, the series of exciting troubles caused by the teacher only strengthens their suspicions...!? Furthermore, Abikura is summoned to Yukishita's house, where for some reason he ends up receiving service from Ms. Hiwamura, who is dressed as a cat-eared maid.
