A young girl moves to a town by the ocean and joins her school fishing club, and has various adventures.

Hina Tsurugi and her family have just moved to a quaint seaside town. Hoping to savor the sight of the peaceful ocean, Hina stumbles upon a girl named Yuuki Kuroiwa-an upperclassman at her new school-who invites Hina to join her in fishing. Hina reels in an octopus, which falls onto her; being afraid of bugs and big creatures, she panics and begs Yuuki to remove it from her. Yuuki sees this as an opportunity to force Hina to join the school's Breakwater Club-a club where members gather, catch, and eat various types of marine life as their main activity. Although her attempts to refuse to join fail, Hina slowly begins to discover the hidden joy in fishing. Her view on the sport changes, now looking forward to all the delightful experiences she can take part in alongside her fellow club members.—MAL Rewrite
