Izuku Deku Midoriya and his fellow students in Class 1-A of UA Highs hero course have been chosen to participate in a safety program on Nabu Island. To further improve their skills and gain experience in more ordinary heroics, the students aid the kind citizens with small services and everyday chores. With the low crime rate in the quiet community, all seems well and good, but the rise of a new villain threatens to put the students courage to the test and challenge their capabilities as heroes.
