The boy is a kidnapped bought infant that was experimented in a nomu lab and was raised inside a glass tank, never seeing the sun nor leaving the tube, asleep. That was, until the heroes found him.

Izuku Midoriya, being quirkless, was told that he can't be a Hero like his peers will be. On normal high school hero-training means, that is. Determined to achieve his dreams and help those in need, Izuku took the old normal and longer way, starting by picking up the trash in their neighbourhood and helping the elderly cross the road.
