Yako's Yorishiro

Yako's Yorishiro was the most precious possession of Yako, and what gave her the supernatural powers she possessed.

Appearance
Yako's Yorishiro is a pair of gray scissors that are used to cut hair. The scissors are very ancient looking, hinting towards Yako's long lifespan. After it became a yorishiro it got a black seal with red japanese letters spelling "封" or "seal" when translated to english.

History
The scissors were previously owned by Misaki, and he used them to cut Yako's hair. Yako was very moved by this act of kindness that she wasn't used to, and forms a crush on Misaki. After Misaki's death the scissors became very precious to Yako, as they were the only thing she had left of him.

During The Misaki Stairs Arc Yako's powers have gotten out of control due to a change in her rumours. Because of this, a few students have gone missing and Hanako, Kou and Nene decide to go rescue them. Yashiro Nene rips the seal off Yako's scissors, which ends up destroying it. This weakens her powers greatly and returns the kidnapped students back to normal.

Trivia

 * Yako's scissors are the first yorishiro to be destoyed in the story and by Yashiro Nene.
