Souichi Negishi is a shy young man who came from the rural Ota Prefecture to Tokyo for college and wished to become a kindergarten teacher. However, for some reason he became the singer and songwriter of a metal band named "Detroit Metal City," with a stage name "Johannes Krauser II." Whenever he wears the heavy makeup, Negishi becomes a completely different person, shouting the most vulgar profanities beyond anyone`s imagination. With the popularity of DMC increases, Negishi starts worrying his double personalities can have negative effects on his (romantic) life off stage.
