The war between the heroes and the League of Villains has reached its breaking point. Across Japan, cities burn as the combined forces of the League of Villains and the terrifying All For One overwhelm the world’s greatest heroes. Pro Heroes fall one after another, and even the students of U.A. High School are pushed beyond their limits. Class 1-A and Class 1-B fight with everything they have, but courage alone is no longer enough. As hope begins to fade, a desperate plan is formed within the battered walls of U.A. The heroes must reach beyond Japan’s borders and call for aid from allies around the world. With civilization hanging by a thread, international heroes answer the call, bringing new powers, new strategies, and a final chance to turn the tide. But while heroes gather from every corner of the globe, All For One prepares his greatest move yet—one capable of ending hero society forever. In a battle where victory seems impossible, the fate of the world will depend on whether heroes can stand together before darkness consumes everything.
