On the way home from her Hatsumōde visit, Mana witnesses a yōkai dragging a human corpse. According to Medama-Oyaji, that was the yōkai called Kasha. Kasha is a yōkai that loves to eat corpses. In the past, he used to steal corpses from funerals and crematories, causing havoc. However, the one Mana saw was weak and immediately dropped the corpse, fleeing upon being noticed. Perhaps he has gotten old... Nezumi-Otoko was eavesdropping, and comes up with yet another nasty plan.
- Black Comedy Cannibalism: More of Black Comedy To Serve Man for Kasha, as Nezumi-Otoko's buisness of getting rid of unwanted corpses is played relatively light. Becomes a more straight example and drops the Black Comedy, when Kasha in Kitaro's body is about to eat a corpse.
- Bluff the Impostor: Mana uses this to figure out if the one beside her is Kitaro, by asking what fortune she got at the shrine as she never told Kitaro her fortune.
- "Freaky Friday" Flip: Kasha has the power to switch bodies by grasping the person's hand. He goes through several bodies, being Nezumi-Otoko and Neko-Musume, before deciding to take Kitaro's body. Later after he's returned to his original body, he finds the man who tried to get away with tax fraud and switches with him.
- How Do I Shot Web?: Averted. No one has trouble using the powers of the bodies they've switched into.
- Ineffectual Sympathetic Villain: Kasha is this in his old age at first. However he becomes a Not-So-Harmless Villain after gaining enough yokai power to switch bodies.
- Out-of-Character Alert: Happens several times.
- Neko-Musume notices something different about "Nezumi-Otoko" and doesn't feel the urge to hunt him like she usually does.
- Kitaro and Medama-Oyaji are confused by "Neko-Musume"'s firm advances.
- Shipper on Deck: Medama-Oyaji blushes when "Neko-Musume" is being more assertive to Kitaro that day.
- Showing Off the New Body: When Kasha switches to Neko-Musume's body, he is amazed by the agility and fighting prowess.
- Voices Are Not Mental: All of the characters who have swapped bodies uses the bodies' voices instead.
