Ninja Bugei-chou Pilot Film

The Ninja Bugei-chou pilot film was created in 1969 by director Nagisa Ooshima. It was initially intended to be a TV animation based on his 1967 film, but the project was rejected by Shirato, who had created the comic series it was based on. As a result, the production was shifted to animate Ninpuu Kamui Gaiden, a side story from the Kamui Den manga, although Ooshima did not work on that project.
