Yako

Yako (ヤコ) is a supernatural haunting a set of stairs at Kamome Gakuen. She is the current representative of the 2nd School Mystery, The Misaki Stairs.

Appearance
Yako first appears as a beautiful woman with long beige hair worn, tied up with a red and white ribbon that has small bells on it, reminiscent of fox ears. Her eyes are bright green. She wears a patterned kimono with a white outer gown and white gloves.

Her real form is a small white fox with a red bib tied around her neck. She has bell earrings, similar to the ribbon in her human form. In the past, she was an inari statue in front of a temple gate, presumably near Misaki's schoolhouse.

Personality
Yako is prideful supernatural who thinks little of humans other than her beloved deceased Misaki. She was willing to do anything to bring him back. She has little understanding of humans and their anatomy. As a result, she employed the help of students to rebuild Misaki's body and had no qualms with removing them if she deemed the bodies they created inadequate.

Later, she admits while her rumor was altered by Tsukasa, she retained full control of her actions. She describes it as a side of her that she often kept bottled up, but was then dragged out by force.

She prefers to be treated with respect, asking others to call her by her name instead of calling her "Fox". In moments of vulnerability, she lashes out by biting others or verbally berating them. However, she still has a bit of a soft side, as seen when she comforted Kou after hearing about the incident with his friend, and even allows him to call her "Nee-san".

Transformation
Yako is able to shapeshift between her human and fox forms at will, although the fox form is her true one and it is the one she assumes outside of her own boundary.

Number 2's Powers
As the School Mystery Number 2, Yako has command over the Misaki Stairs — her boundary. It can be accessed by stepping on the fourth step of the stairs.

In the boundary, Yako is unbeatable and other School Mysteries are not able to use their own powers unless she permits them to. Her weapon of choice is a giant pair of scissors. If one were to get clipped by them, the impacted body part will turn into a doll part. Additionally, Yako has small kokeshi dolls that she can control to perform tasks. The dolls are often used to restrain her subjects while the pair of scissors attack.

It is later revealed in the Mirror Hell arc that she has control over space in the Seven Mysteries. Within her boundary, she is capable of accessing other areas, such as Number 3' s boundary. With Yako removed from her School Mystery seat, her boundary is still accessible despite the lack of care.

 * "My goodness, you're fragile. Did our little game upstairs take that much out of you?"
