Reflecting the Japanese fascination with western culture, this musically-charged comedy concerns Souichi, a sweet natured, slightly backward pop fan who aspires to recording stardom. He naively moves to the city of Tokyo expecting to hit the charts overnight as a pioneer of soft, sentimental romantic ballads. Naturally, that doesn't happen, but Souichi encounters even greater success with an oddball gig that involves donning demon makeup and a black cape as a front man for the band Detroit Metal City. By day, Souichi remains the ineffectual and timid young man well-liked by everyone; by night, he's a crass, loud, frightening monster named Johannes Klauser II who earns his paycheck screaming rants onstage about rape and murder, to the delight of thousands of shrieking goth metal fans, some of whom actually believe he is a demon incarnate. His life grows problematic when he reencounters and falls hard for a university crush, Ms. Aikawa (Rosa Kato) - an equally timid, beautiful young pop critic who will almost certainly disapprove of his lifestyle after dark - if she ever finds out.
