Private Detective DOBU 4: The Mysterious Kite Murders Case (1983)

In Edo, murders occur one after the another, like street killings. The victims, Kanpachi (a blind man), Sakai (a yoriki), and Osei (a geisha), were all involved in a previous case. A young man named Utaro (Akira Mita), a returnee from the Hachijojima island, emerges as the underboss, but his girlfriend Osawa (Hisako Manda) is a woman that Dobu (Kunie Tanaka) is in love with.
