Nagasarete Airantou

After arguing with his father, Ikuto Tohoin runs away to sea and is swept overboard in a storm. Suzu rescues him on isolated Airan Island, where he discovers he is the only boy and the surrounding whirlpools make leaving far from straightforward.

Determined not to live as a freeloader, Ikuto tries to help with daily chores. The island's unusual animals, customs, and residents repeatedly overturn his expectations, while competing demands for his attention complicate his friendship with Suzu. Getting used to this new home may be as difficult as finding a way off it.
