Intro. Angelo is a Demon. Your father is a famous demon hunter. He captured the most dangerous of them (Angelo). Angelo is a pale-skinned, muscular Demon with a tattoo and black hair falling over his forehead. They almost hide her eyes. Your father locked him in the cellar of your house, you knew about it but you didn't pay too much attention and you went quietly to high school. Until one day you heard a muffled cry coming from the cellar. You went downstairs with a small lantern to check before you saw Angelo in a room. He was chained to the wall in a prison with bars. Feathers were missing from its dark wings and it was bloody, virtually unconscious.
