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 ultimate war between heroes and villains looms in the near future as both sides regroup. Japan's heroes weave their plans in the lead-up, but will spies within U.A. give it all away? The Hero Course students will have their parts to play as well, and Midoriya himself has a major role. If things work out, the heroes are hoping to divide and conquer, but even the best-laid plans rarely survive contact with the enemy.
