Souichi Negishi is a shy musician whose dream is to become a pop singer. Instead, he ends up as Johannes Krauser II -- the lead singer and guitarist of the death metal band 'Detroit Metal City'. What follows is a series of comic events involving the geeky Negishi's transformations into the death metal icon he hates so much.
Both deal with a young man who despises one style of music, but becomes involved in it. He wears a mask when he performs, therefore no one other than the people around him knows his real identity. While being involved with the music he hates, he unknowingly starts to like it and becomes a star.
