Synopsis by Donald Guarisco
This is the final film of Shintaro Katsu's Goyokiba trilogy. Unlike its wilder, sexier predecessors, Goyokiba: Oni No Hanzo Yawahada Koban is a moodier, less thrill-oriented affair. This time, Hanzo's accidental discovery of a cache of hidden gold causes him to become suspicious of local treasury officials. He investigates to determine who could have stolen the gold from the seemingly impregnable treasury building and discovers a conspiracy that revolves around a sinister loan-sharking scheme. Like the other films in the series, Goyokiba: Oni No Hanzo Yawahada Koban was inspired by the Kazuo Koike manga and includes some swordplay and wild sexual situations but surprisingly downplays them in favor of pursuing its corruption and social-division themes. As a result, it ends the series on a surprisingly moody note. Goyokiba: Oni No Hanzo Yawahada Koban is also notable for being the final feature directing credit for Yoshio Inoue.
