Santa Company: Manatsu no Merry Christmas

When Mint and her colleagues from Santa Company travel to a tropical island situated just below the equator, they anticipate an ordinary visit. Instead, they are immediately confronted with an overwhelming environmental crisis: a massive mountain of ocean debris that has washed ashore. What began as countless small acts of human carelessness has steadily accumulated over time, transforming into a towering physical problem that threatens the natural beauty of the island. Faced with this daunting sight, Mint and her companions must determine exactly what kind of challenge they have stumbled into and how they can possibly address the sheer scale of the pollution before them. The situation forces the team to reckon with the real-world consequences of neglect, turning their tropical excursion into an unexpected mission. This unusual predicament sets the stage for a narrative that defies traditional holiday expectations. Blending environmental awareness with seasonal charm, the story unfolds as a splendid yet decidedly strange secret Christmas adventure, proving that the spirit of the holidays can emerge in the most unlikely and sweltering of places.
