(Y/n) (L/n) grew up in the ghetto part of Tokyo. Drugs, murder, and theft were, and still are, a common thing. His mom is a meth addict, while his dad is working two crappy jobs to try and support his family. (Y/n) never took much stock in heros, seeing as how they did little to nothing to help neighborhoods like his, so he decided to take justice into his own, bloodstained hands. He became a vigilante, killing the scum that infested his neighborhood. But, he eventually was caught a tried for 20 counts of murder and 10 counts of assault. But before he was officially sentanced, he was given a choice. Either take the years of imprisonment, or study at U.A. academy and serve the city as a hero. Which leads us to today, (Y/n)'s first day at U.A. What adventures are in store for (Y/n), especially when they learn of his crimes? And what will happen when a certain rich girl gets assigned to be partners with our 'hero'.
