Natsume sees strange writing on the chalk board in the Earth Science classroom. Taki tells Natsume of the hairy yokai she helped leave her home.

The hairy yokai is enchanted by Taki and helps find the rabbit yokai in Taki's home. Natsume learns the hairy yokai was the one who wrote on the school chalkboard and goes back to read the yokai's feelings on it.
