Santa Company: Manatsu no Merry Christmas

Santa Company secretly delivers Christmas presents to children around the world, helped by trainees known as tonttus who wrap gifts, care for reindeer, and prepare for delivery missions. Mint Rondo arrives at the company’s tropical island branch hoping to become a Santa like her older brother, but her clumsiness leaves her struggling to keep up with the other trainees.

Before Christmas, Mint, Thomas, and Noah discover that the island’s shore and surrounding ocean have become buried in accumulated trash, threatening wildlife and the branch itself. Their usual training gives way to a problem created by countless small acts of carelessness over time. For Mint, it becomes a chance to prove that helping others does not require being perfect; sometimes it begins with being the person willing to start cleaning up.
