Kenji, Asakura, and Oota are indifferent school mates who are infamous for randomly bashing up fellow delinquents. Tired with the routine conflicts that used to give the gang with brief adrenaline, Kenji seeks an alternate source by forming a band on the spur of the moment. He enlists the help of the rest of his crew, picking up the bass, with Oota on guitar and Asakura on drums. Despite having no prior musical instrument knowledge, their first session considerably exceeds their expectations.
