It boasts a time-honored sense of discipline in its filmmaking, bringing in a rather complex plot in at just 83 minutes and setting it against a historical setting with a mixture of villages and towns a la the Zatoichi movies. However, the violence is a few notches more aggressive than what you'd see in Zatoichi film, including bursts of arterial spray that act as an exclamation point at the end of a sword duel and the occasional shock like a severed limb or a bit of eye trauma. There's also a memorable ninja trap for the hero where he is attacked by a squad of topless female ninjas posing as fishing girls.
