Soichi Negishi is a shy and gentle young man who dreams of a career as a pop musician. Dreams don't pay the bills, so he's ended up as the lead singer and lead guitarist of a death metal band called Detroit Metal City. In stage costume he is Johannes Krauser II, rumored to be a terrorist demon from hell. Negishi despises DMC and all that it stands for, but so help him, he's a terrific performer and can't walk away from that. As DMC's star rises Negishi tries to satisfy both worlds, but can't.
