Boku no Hero Academia the Movie 1: Futari no Hero

All Might takes Izuku Midoriya to I-Island, an advanced artificial city where scientists and hero-support engineers gather for the massive I-Expo. There Midoriya meets Melissa Shield, the Quirkless daughter of All Might's old friend David and a gifted engineer in her own right. He also discovers that several of his Class 1-A friends are visiting the island.

The celebration becomes a hostage crisis when armed villains seize the security system and neutralize the professional heroes. With the adults trapped, Midoriya and his classmates must move through the island on their own, protect Melissa, and uncover a scheme whose most important target is tied directly to All Might's past.
