Midoriya inherits the superpower of the world's greatest hero, but greatness won't come easy. 
What would the world be like if 80 percent of the population manifested superpowers called "Quirks"? Heroes and villains would be battling it out everywhere! Being a hero would mean learning to use your power, but where would you go to study? The Hero Academy of course! But what would you do if you were one of the 20 percent who were born Quirkless? 
The plan to engage the villains on the heroes' terms has mostly succeeded. Now in different locations around Japan, the heroes and U.A. students take on the villains in all-out battles! First, Todoroki squares off against Dabi with terrifying intensity. Elsewhere, Endeavor and Hawks hope to turn the tables on All For One, but the villain mastermind has one last trick up his sleeve. Finally, it's Tomura's new and improved body versus the crew at the airborne U.A., where the youngest heroes have critical roles to play!
