Darkside Blues (Japanese: ダークサイド・ブルース, Hepburn: Dākusaido Burūsu) is a manga series by Hideyuki Kikuchi. The story has been adapted into an anime film directed by Yoshimichi Furukawa. The film was originally licensed by Central Park Media and then later licensed by ADV Films. The story involves the town of Kabuki-cho, home of a resistance faction called Messiah. In the futuristic setting, Kabuki-cho is one of the last places of freedom because the Persona Century Corporation has taken control of the majority of the Earth. Kabuki-cho is hence known as "The Dark Side of Tokyo". Furthermore, a mysterious stranger called Darkside appears to protect the citizens of Kabuki-cho.
