Kenkou Zenrakei Suieibu Umishou – Season 1

The team attends the local swim competition and ends up in last place. The team captain can't concentrate on the swim meet that they're at because his father's restaurant is in financial trouble. To help his family out, Amuro and the other swim team girls spend a few days serving customers wearing only aprons and swimsuits. Naturally, this attracts a lot of men.
