Human or demon, a question for one Midoriya Izuku. Well, certainly not demon... not entirely. He was just another aspiring Pro-Hero, ignoring his sharper than usual canines and the displaced air whenever he took a deep breath. Kokushibo was well aware he had raised a monster. Not an evil monster, but a monster nonetheless. This is a fic I found on ao3 written by SpiritArchive. All credits go to him I just wanted to move this onto Wattpad.
