A famous private school located in a certain ward in Tokyo, where high-income people gather, has a swimming club that has top-notch financial resources but no track record or ambition. Yuuri Adachi is the new member of the school's club, where the sons of rich people are having fun. There's no point in half-baked reinforcements...She has a hot-blooded side, and decided to choose the ``most rational attire for a competitive swimming coach.'' She appears by the pool in a competitive swimsuit with her breasts completely exposed, which can only be described as something that can only be said to be beyond common sense. Will she save the struggling swimming club and the adolescent boys? Or will she eat them?
