Class 1-A goes to Nabu Island, where they get to do some actual hero work for the first time. The atmosphere is so relaxing that it feels like you're on vacation... Until they're confronted by a foe with an inexplicable Quirk! His strength is disturbingly familiar, and Shigaraki appears to have played a role in the scheme. There's no time for questioning now that All Might has retired and citizens' lives are on the line. Deku and his companions are the island's only hope, and they are the next generation of heroes.
