An animated pilot film for Ninja Bugei-chou released to the public over three decades later on Ninpuu Kamui Gaiden DVD volume 7. The pilot film was created in 1969 as director Nagisa Ooshima was wanting to make a TV animation to build off his controversial film from 1967. The pilot was rejected by Shirato himself (the original comic creator the film was based on) and the plan was changed to animate Ninpuu Kamui Gaiden instead, a side story to the Kamui Den manga also created by Shirato. Though with this change, Ooshima did not partake in Ninpuu Kamui Gaiden's production.

Based on the book by Tsuboi Sakae, which drew on her involvement in Japan's anarchist counterculture and opposition to Korean War rearmament. Combined live action (handled by Akio Jissoji) and animation (handled by Shigetsugu Yoshida). Released as a TV special. (Source: AniDB)
