A female Zunbera appears in episode #15 of the sixth anime adaptation, Zunbera Spirit Surgery. She appears before a running Kirara Fusano while resembling an old woman and realizing the girl is suffering as a result of the mistreatment she gets due to her ugly face, Zunbera offers to do Spiritplastry to help her overcome her problems. At her home, Kirara is not convinced that she can be change her face to resemble one of her artworks, until Zunbera removes her old woman appearance and adopts a younger and more beautiful one and claims she can help her. Kirara is disturbed from this and claims she does not have any money, but Zunbera claims she has no need for it. She prepares Kirara a "Soul Tempura" for her to consume, and as she is unconscious Zunbera performs the procedure and is successful. As she was doing this, Nezumi-Otoko was watching from out the window and forms a scheme from this.
She had formed a partnership with Nezumi-Otoko after this, and does her Spiritplastry on another girl who was jealous of Kirara. She is visited by Nezumi-Otoko after this, enjoying that he can get money from sending people to her and asks if she is really okay with having no share of the money, which she states to him that she has no need for money. However when Kirara is left faceless, Mana Inuyama requests Kitarō's help and they bring the jealous fan as well, requesting Zunbera to explain herself. She reveals how Spiritplastry works, where it has the patient wear the face of dead people, showing a box of faces. When asked if there is away to return to normal, she simply states that all they have to do is wear their original faces again.
Kitarō finds her compliancy strange and asks what her end goal is, which she merely responds that she is not after anything, but that she finds human women's desperation for beauty to be precious. Medama-Oyaji tells them of a rumor he heard of her origins, in which she was a human who drank mercury to become a yōkai. The jealous girl takes her face back, but Zunbera asks if that is what she really wants, as she came to her for to be beautiful, stating that the procedure can be reapplied as many time as needed, but Neko-Musume warns that doing so could turn them into yōkai, questioning whether she would be happy smiling with her own face, which she wears her face again. She watches as Kirara is visibly conflicted as she believes her face has brought her nothing but trouble, dropping it and running away.
After Kirara decides to put her face back on, Kitarō requests she stops taking people's faces, but she claims she will not do anything, unless women com to her for help, leading Neko-Musume to claim she is a "foxy" one. Later it is seen that Kirara is with her beautiful face once more, though it is unknown if she underwent Zunbera's services again or normal plastic surgery.
Spiritplastry (霊形手術): Also called Spirit Surgery, Zunbera has the ability to remove people's faces and grant them the face of dead people, thus effectively performing her own kind of plastic surgery. The process does not look to be painful, as after Kirara consumed a "Soul Tempura", she was unconscious as Zunbera was performing the Spiritplastry. However the effects are temporary and the procedure must be reapplied. Doing so consecutively however, may turn the human into a yōkai.
- Face Preservation: Through an unknown technique, Zunbera is capable of preserving the face of dead people, which won't decay with the passage of time. Even faces removed from living people can be preserved and reapplied if needed.
Zunbera was based on Zunberabō (ずんべらぼう) which was depicted as faceless humans similar to Nopperabō in Shigeru Mizuki's artworks. In fact, it is often regarded as either an alias or subspecies of Nopperabō, however Zunberabō in Aomori Prefecture shocked a man to death while Nopperabō tends to scare humans.
