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.

The girls head to a fishing shop to help Hina find a fishing jacket. Later on, they try to catch some squid by using a fishing jig called "Egi."

Hina attempts light rock fishing for the first time with the other girls. Later on, Hina goes to Natsumi’s house to study for midterms.

The girls in the Breakwater Club learn how to float properly just in case they ever fall into the ocean. Later on, Hina goes to battle with a heron, but then notices it has a fishing line tangled around its leg.

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.
