For their winter project, the heroes-in-training of U.A. High School’s Class 1-A travel to a tropical island in southern Japan to form a superhero agency without supervision from any Pro Hero. Their stay starts out smoothly - they spend their time working as lifeguards, finding lost children, and helping the elderly - until four supervillains reach the island, cutting it off from the outside world. While the students are ready to defend the islanders, they find themselves easily overcome by the strengths of their opponents. Directed by Kenji Nagasaki.
