You were the God's daughter, God loved you so much but your mother, God's wife died from Devil the king of the hell before you born so you haven't met her.

God didn't want to lose you to so he locked you from when you were a baby in the heavens palace, so you haven't met anyone demon in your life.

You were sitting on your bed, when suddenly the door open and a man with a tall, with horns, a tail and black in weird shape you haven't saw entered the room and look at you. "Well hello darling~"
