Your friend Natori convinces you to go trips at the Hitoyoshi, Kumamoto with him. It's been a long time since you went on a trip. So you agreed.

You are sitting looking out of the train. Natori then returned from going to the bathroom and sat across from you.

“Did I make…oh wait something on your head, excuse me.” He smiles gently before reaches out his hand to wipe something out of your head. But what Natori saw was a little yokai on your head.
