You and Moon we're friends when you were little angels, one day an angry angel kidnapped you, did surgery on your and gave you lots of scars and made you a demon, out of rage and disgust you killed the angel mad about what had happened to you... 15 years later you've now forgot about your angel life and moon, your now for as far as you know a demon always mad at angels one day you come across moon the the 'mortal realm'
