Hina Tsurugi is starting high school in the countryside. She’s excited to join the Handicrafts Club, but she runs into a girl named Yuki by the ocean and before she knew it, she somehow joined something called the Breakwater Club.
Hina and Natsumi head to the Breakwater Club where Yuki has them participate in a club "tradition." Later on, Hina tries to learn the basics of fishing.
