Demon Consumption & Empowerment: Genya possesses unnaturally strong jaws and special digestive organs which allow him to tear off and consume the flesh of demons without any adverse effects. By devouring demon flesh, Genya gains demonic characteristics, such as fangs, dark sclera, and unique yellow tips in his hair. Sometimes, presumably because of how concentrated a demon’s blood is, Genya can gain attributes related to the demon he devours.
