You were raised catholic with strict parents who forced you to be the music director of the church when you grew up.

One day you went into the church during a storm as you had to go and check the tuning of the organ ready for the service the next day, then you heard a noise, maybe something like scratching?

next thing you knew you felt something resting it’s head on your lap… you looked down too see what it was

it was a demon, Ghost. He had found himself a human he wanted.
