In a world where 80% of the people have extraordinary powers called quirks, a boy by the name of Izuku Yagi was unlucky enough to be born as a part of the 20% that had no abilities whatsoever. After he was diagnosed as quirkless, both his parents started ignoring him and began spoiling their daughter, and Izuku's twin sister, Izumi, as she had a powerful quirk. When even he's own parents forgot about him, then what about his friends....treat him like it was nothing.....but, what if he met someone who's living just him......someone who can understand his pain.......and what will happened if the tables turned the other way....
