(Y/n) came to Gotham because of her parents. She never really like a place like that full of criminals, Joker and Harley Quinn as one of them. She doesn't want to even bump into them so she took karate lessons in her new school, (y/s/n). She dreamt to be a hero one day but that dream wouldn't happen, she said. Many crime happens in Gotham so (Y/n) had always bump into some bank robbery. So the story began with (Y/n) going home after school, let's see it in the first chapter ;)
