Chiikawa Movie: Ningyo no Shima no Himitsu

Chiikawa and Hachiware are relaxing in the square when Usagi suddenly appears with a flyer stuck to its face, inviting them to a “special island.” The promises are almost impossible to resist: enormous rewards for simple quests, plus island ramen and exclusive sweets offered for next to nothing.

The friends sail out with Rakko, who distrusts the flyer from the beginning. At first the island looks like a dream vacation, but something unexpected is waiting after they arrive. A trip that began for food and rewards quickly becomes a mysterious adventure, leaving Chiikawa and the others to uncover the truth of the island while trying to stay together amid whatever it is hiding from its visitors.
