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?

With society wavering on the verge of collapse in the wake of the recent chaos, Midoriya has left his school and friends behind in order to save whatever lives he can out on the streets and lure All For One into the open. But the mastermind villain has his own plans and sends villains for hire after Midoriya, including one familiar face. Chief among these hired guns is Lady Nagant--a fallen former hero who delivers plenty of bang for her buck.
