When a beautiful woman appears she’s initially delighted to find that Nene, Kou and Hanako have constructed a human-ish body. But when she makes it move, it crumbles into a pile of parts; another “failure”she’ll add to the growing heap behind her, where Aoi and all the others who fell into her stairs lie, neither dead nor alive.
However, her scissors have the ability to turn a human (or a part of them) into a doll, so Hanako reiterates their goal of finding Misaki’s Yorishiro (or weakness). If the highest spot isn’t the deepest, then perhaps the lowest spot is…so he shoves Nene off the edge, and she falls, falls, and falls some more.
When she comes to she’s lying near the gate to a temple, surrounded by concerned Mokke. She finds a desk, an old photo, and a notebook that contains a kind of dialogue between a girl and her handwriting teacher. The handwriting gets better as the pages go on, but one day the teacher, named Misaki, doesn’t return.
Misaki, then, isn’t the woman in the kimono trying to turn everyone into dolls, but the teacher who abandoned her, likely when he died, or simply moved away. In any case, Nene now knows the woman’s weakness: a pair of haircutting scissors gifted to her by Misaki.
When the lady finds Nene and attacks her, Hanako intervenes, protecting Nene and giving her cover to make a run for the shrine containing the scissors. While the woman’s story is a sad one of unfulfilled love, she’s gone too far and way beyond her duties as a School Wonder. With her Yorishiro broken, Hanako strips her of her power.
Back in the realm of the living, Nene is safe and sound, while both a doll-ified Aoi, Kou, and all the other victims will be restored to their humanity. They were never dead, just trapped in between worlds. Then Hanako reveals the true form of the woman: an Inari statue in the form of a kitsune, or fox spirit.
In the past, Misaki-sensei befriended the ghost who inhabited the kitsune statue, name turns out to be Yako, and even included her when a photo was taken of him and his class. Yako grudingly agrees not to continue her mischief, but isn’t in a hurry to befriend Nene nor anyone else.
This latest School Wonder case thus solved, the black crane, really a black Haku-joudai hiding in Nene’s hair, returns to its master, who then returns it to his master, a green-haired girl wearing the same uniform as Nene. She seems pleased things worked out. I assume at she’ll reveal herself and her intentions to Nene and/or Hanako at some point.
