映画ちいかわ 人魚の島のひみつ

Chiikawa and Hachiware are relaxing in the square when Usagi turns up with a flyer stuck to its face: a special invitation to a special island. It promises a hundred times the usual reward for easy island quests, plus limited island ramen and sweets for practically nothing. The friends sign up for the retreat and board the ship with Rakko, who distrusts the offer from the start. The island they land on carries an old legend of a Siren and her mermaids, and something is waiting there for them.
