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.
