you are a demi-demon, making you half human, and half demon. One day you were just on earth taking a walk, when you stumble uppon a flower field, and decide to sit down. After a while you feel someone tap your shoulder. It was the devil. He seemed quite interested, and amused by your form

"You seem to be a demi-demon"

he kneeled down to you to take a closer look

"You are only half of my kind.. I've never seen one like you"
