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? In the desperate battle with All For One and his minions, the U.A. students are pushing themselves to their absolute limits.

Everywhere, the villains have the upper hand. While Ochaco and Asui fight Himiko Toga, and Midoriya squares off with Tomura, the floating U.A. island falls out of the sky.

All For One's new form appears all but unstoppable, and if he reaches Tomura, all is lost. But one hero stands in his way.
