Mizoguchi reveals to Heishirō that he killed Koharu's father, and has since never drawn his sword on another man, despite his immense skill. They then go to find Kazamatsuri and rescue Koharu. While Mizoguchi stalls Kazamatsuri, Heishirō takes Koharu aside and says he will marry her if Mizoguchi wins. Kazamatsuri fights Mizoguchi, who only draws his sword after his opponent destroys his wooden sword. He then disarms Kazamatsuri near a cliff. Kazamatsuri, admitting defeat, commits suicide by jumping off the cliff. Heishirō and the others go to the bottom, where there is no sign of Kazamatsuri's body, but Koharu spots the stolen sword at the bottom of the river, where Heishirō retrieves it.
