Nightmare Hero, Terror (OCxBNHA)

Quirks, the powers which lived inside the body of human and grant the super powers to the owner. When the era of quirks comes, the society broke down into pieces. Quirkless, heroes and villains. This is the story of a young boy who is feared by the either side of the society and he's also suffering from the mental illness. Could he become the strongest no.1 hero? The only thing I can say is, he will surely become the Symbol of Terror.
