Genesis

Genesis (そうせいき Souseiki) is a Demon, and the Fourteenth Damned. Genesis is the "king" of the demons, being the most powerful, though he is technically the youngest. Beginning the original revolt against the other Gods, by killing their king in cold-blood. The demon can easily rival even the most powerful mortal mages in raw power. Due his legendary status, and the way he boldly declared what was wrong, the truth about the deities, myths have named him The Embodiment of Truth (ぐたいかじじつ Gutaika Jijitsu) a title which he enforces daily.
