It's your fault I'm like this

THIS IS MY FIRST STORY! Deku was diagnosed quirkless at the age of four. He was bullied at school and ignored at home. When his life there gets to the point of Inko abusing him as well, he takes Bakugou's advice and jumps off the school roof. But in doing so, he gained his quirk. So, with this quirk, he runs away and takes japan by storm and becomes the number one vigilante!
