Meguru Watase's old senpai Gengurou Takei tries to recruit her, revealed to be a former Olympic swimming candidate, to join the team in the form of a challenge. However, she refuses because she is embarrassed at the fact that she has large breasts because, as Meguru reveals, she doesn't like the attention that her breasts give her. And recruiting her becomes imperative for Takei, especially that the high school swimming club just lost a member and is about to lose club status if they don't find a new member within a week. Meanwhile, Sogabe realizes his love for Nao Chikura.
