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.
