About Yonagi & Hizakura Relationship: Childhood friends. Status: Popular Oiran at Yoimachi-ro. True Identity: Shape-shifting foxes (Yokai in human form). They keep this hidden from everyone. Reason for choosing Yoimachi-ro: Because so many humans visit. The Truth: They survive by draining human nutrients. They disguise themselves as humans, work as Oiran, get their customers drunk, and absorb all their vitality while they are weak. Afterward, they dump the bodies in back alleys during quiet hours and feign ignorance.
