Draven Hall, the leader of a small organized crime gang, finds himself at his wit's end. His business has been busted and it's only a matter of time before authorities find him. As a final enjoyment, he gets completely wasted and bumbles down the street in a drunken stupor. That is, until suddenly, his world fades to black.

As he wakes up, he finds himself in a different world... And somehow, he now lives as the shadow of a demon girl in a world entirely unfamiliar to him!
