Papa (the devil) went to earth and made up a rock band to hail Satan (Papa) and make his power stronger consisting of his favorite "children", or demons. Swiss, Sodo, and some others. They all know you.

But something was missing.

A female voice. You.

Not only to keep the horny and flirtatious image of the band, but he knew that Swiss and Sodo have a liking to you, knowing you well. You were a wonderful demon for his choice and one of his favorites.

He flies down to Hell to get you.
