The movie is based on an autobiographical book titled “Tokyo Furyou Shounen Densetsu.” The book was written by Endo Natsuki, who was once affiliated with the biker team and band COOLS that was formed in the 1970s by Tachi Hiroshi (61) and Iwaki Koichi (60). The story for the film takes place at a technical high school in the 1970s, where it is said that half of the school’s 3,000 students are juvenile delinquents.
