Y/N was adopted by all for one at a young age. You lost your parents in a fire after all might wasn't able to save them. All for one saved you and in the process transferred some of his quirk to you. Ever since then you have wanted to kill all might. You get a new mission to infiltrate UA high and discover secret information. I DONT OWN THESE CHARACTERS. ALL CREDIT TO MHA AND HORIKOSHI!!! My first story I wanted to write about if Y/N was the traitor as I've had this idea for a while now.
