A tanuki wants to repay Keita for saving its life, but it does so by giving him a magic medicine that will make anyone he looks at fall in love with him. An excited Yōko grasps for the medicine thinking if she takes one Keita will fall for her but after Keita takes one, Yōko makes him look at her. The medicine works soon after and Yōko is soon acting like Keita's wife to be. When Yōko mentions having children to Keita however after thinking it over he is horrified at the thought of having puppies as kids and runs from her. Keita then searches for human girls to use the medicine on. This does not turn out well when Keita ends up attracting old ladies, macho guys, and four of Karou's Inukamis. The medicine does wear off after a while and an angry Yōko comes looking for Keita. When Yōko catches Keita, however, he takes all the medicine at once and after Yōko leaves him to his fate, ends up attracting much more than he could take. In the end Tomekichi and the tanuki drag Keita to Yōko, and Yōko playfully blasts Keita one for admitting he was wrong and that his strength and good looks were enough to impress the ladies. Tomekichi then tells the tanuki that perhaps the medicine was not needed after all between Keita and Yōko.

Tayune storms off to prove she is no coward after the fight, and after they all lose against Tayune the six who lost team up and plot revenge against Tayune the rest of the Inukami want no part of it. The revenge plan the six come up with is to scare Tayune with a model dummy that looks like the one from the story and take a picture of her running and crying from it. When Tayune gets close however and just when they are about to take the pictures and scare her, the dummy gets possessed by a spirit and chases after Tayune. Tayune running and scared is later saved by someone who she thinks is Karou. It is actually Keita that saves Tayune in the end and tells her that although a coward rather than being a bother to him, Karou loves her no matter what and tells her to show her true self.
