eri and you were kidnapped when you were younger and you used to be quirkless but now you have one or more since overhaul experimented on you. Your overprotective of Eri as she is the only family you have left. You were always kept in chains and in another room but Eri visited sometimes so you wouldn't destroy the place. Eri had run away and found the hero but she was being punished right now and she always had a specific tune she would whistle when needing help. Like in this moment she was whistling and you reacted immediately, you had been sleeping but woke up and broke out of the chains as you teleport to Eri. Overhaul was taking too much blood and it was hurting her, you held her close to you and protected both of you with one of your quirks or quirk. Overhaul sighed how did you let them escape!? he screamed at the henchman as he knew you wouldnt let her go now. He looked at both of you and the henchman got out the weapons as overhaul said get them separated you did hear other unfamiliar people coming, maybe heros ?
