Midoriya inherits the superpower of the greatest hero in the world, but greatness will not come easily.

What would the world be like if 80% of the population exhibited superpowers called "Quirks"? Heroes and villains would fight everywhere! Being a hero means you have to learn to use your power, but where would you go to study? At the Hero Academy, of course! But what would you do if you were part of the 20% born without a Quirk?

The joint battle training of Class 1-A with Class B continues! Class 1-A wins the first victory in the five-match series with full Quirk battles, but after some comments from the teachers, the students face off again for a second round, and real rivalries form.
