This is less a show than a rescued artifact, and watching it feels like reading someone's rejection letter out loud. Nagisa Oshima had already turned Sanpei Shirato's Ninja Bugei-cho into that notorious 1967 feature built out of the manga's own pages, and in 1969 he wanted to push it into television animation. Shirato said no. The plan pivoted to Ninpuu Kamui Gaiden instead, a side story off Kamui Den, and this pilot sat in a drawer for over thirty years until it surfaced as a bonus on volume 7 of the Kamui Gaiden DVD. That is the whole appeal: a few minutes of the anime industry's road not taken, killed by the creator whose work it was adapting, preserved because someone doing DVD extras decided it deserved better. Slept on for obvious reasons, and worth digging up anyway if you care where things could have gone.
A ninja operates in the shadows of feudal Japan, moving between warring clans and personal vengeance. When director Nagisa Ooshima adapted Sanpei Shirato's controversial manga into animation, he envisioned something raw and uncompromising: a portrait of a shinobi caught between duty and survival, with action sequences that mirrored the visceral violence of his provocative live-action work. The pilot captures a single, brutal mission as the protagonist navigates hostile territory, facing enemies who blur the line between ninja and common soldier. Ooshima's vision prioritizes gritty realism over heroic spectacle, grounding the ninja tale in political intrigue and moral ambiguity rather than fantastical flourishes. Though ultimately rejected and shelved for decades, this fragment reveals what could have been: a darker, more challenging interpretation of the genre. Fans of grounded action with historical weight and those curious about experimental animation from this era will find something genuinely different here, a road not taken in anime history that finally emerges from obscurity.
