Teito Monogatari Gaiden

Teito Monogatari Gaiden is a Japanese horror/dark fantasy film. It is a spin-off of the Teito Monogatari franchise. It is not based on the original novel, but rather adapted from a side story novel, Karakuri Doshi. Like the animated adaptation which preceded it, the film is much darker, more violent and sexualized than its predecessors, and deviates greatly from its source material. It was released through V-Cinema in 1995.
The film was advertised as being a direct sequel to Tokyo: The Last War going so far as to include a silhouette of actor Kyusaku Shimada in many of the promotional materials. However the movie was produced by a completely different studio and worked on by a different creative staff from the Toho distributed adaptations.
