My Hero Academia: Two Heroes

"Who is your hero?"

All Might and Deku accept an invitation to go abroad to a floating and mobile manmade city, called \'I-Island\', where they research quirks as well as hero supplemental items at the special \'I-Expo\' convention that is currently being held on the island. During that time, suddenly, despite an iron wall of security surrounding the island, the system is breached by a villain, and the only ones able to stop him are the students of Class 1-A.
