Composer Kentaro Haneda created the album in 1977, as the soundtrack to a cult detective book series of the same name by writer Seishi Yokomizo. Its 10 tracks mix disco with funk and breakbeats. For the LP, Haneda enlisted a group of musicians including pianist Hideo Ichikawa, Tadaomi Anai on percussion, Takeru Muraoka on saxophone, Kohi Hadori on trumpet, and Kimono Yamauchi on koto.
