Who Are the Eight Devils of Kimon?
The plot that assembles them is a gold story. The Yamashiro clan mines gold in secret for the Toyotomi heir who calls himself the Shogun of the Dark; when a shipment runs aground near the village of Shimoda, the Eight Devils of Kimon exterminate the village to keep the secret. A Koga ninja team sent to investigate is wiped out, its sole survivor Kagero captured by the Devil Tessai, until a wandering swordsman named Jubei intervenes.
Jubei has history with their leader. Five years earlier, Himuro Gemma ordered his own Yamashiro team to murder each other to bury the location of the gold mine. Jubei survived, killed his comrades to do it, and beheaded Gemma, who simply reincarnated: his Devil’s gift is immortality. Blackmailed by the Tokugawa spy Dakuan, who poisons him and holds the antidote, Jubei walks the film as a checklist of duels, one Devil at a time.
