Yume Midoriya is Izuku's older sister, she is 29yrs old and was perceived quirkless at 5yrs old. Inko and Hisashi Midorya kicked her out and decided to start new again years later. Inko, over the guilt of kicking out her daughter decided to keep Izuku even though he was perceived quirkless as well. Hisahsi left claiming that by having 2 quirkless children it was all Inko's fault... Yume was perceived to be dead. Little did the Midoryas know, Yume was still very much alive ... shortly after being kicked out Yume's body developed a quirk out of self-defense and survival... She may be gone but she never left the Midoryas. Never wanting a child to end up like her, Yume kept a close eye on her parents and found out Inko had a quirkless boy. She vowed to keep him safe always, if not in reality... at least in his dreams
