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.

Ms. Kotani stops by again and asks the girls to fish for some li’l horsies so they can have some for dinner. Later on, Hina’s mom finds some old fishing gear and Hina attempts to go fishing all alone.

Hina suddenly becomes assertive and tells the Breakwater Club that she wants to fish for whiting, so they go to Takohigeya to get the proper supplies. But to Hina’s dismay, fishing for whiting usually requires real worms.

Hina is determined to catch some whiting after doing some research online on how to catch them. Later on, Hina teaches Natsumi how to make some felt plushies.
