Black Comedy Cannibalism: More of Black Comedy to Serve Man for Kasha, as Nezumi-Otoko's business 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.
