Umi Monogatari: Marin no Kore Naani?

Life on land gives Marin plenty of questions, especially when it comes to unfamiliar clothes and everyday customs. Alongside her friends, she discovers aprons, school uniforms, pajamas, and maid outfits through a succession of comic encounters.

When everyone tries to help Kanon prepare a boxed lunch for Kojima, their conflicting ideas about ingredients turn a simple favor into confusion. Marin’s attachment to sea creatures makes even an ordinary cooking suggestion a cause for alarm.
