Izuku Yagi: The Monster Inside

When Izuku was 4 years old he was told he was quirkless and his life changed forever. The childlike way he saw the world was irreparably destroyed. Suddenly he was forced into a world where he had to grow up fast to survive. He had to get rid of his fear of the dark because sometimes he ran and hid from Izumi and her gang long enough that it became dark. He can't count the number of times he's avoided drug dealers, gang bangers, and murderers in the pitch-black dark. Through all this Izuku stayed kind, he still wanted to be a hero after all. That kindness is what inevitably got him killed... and it's also what brought him back.
