Season: 1

Natsume meets a spirit who used to be friends with a man who could also see spirits, but one day lost this ability.

Natsume goes to a hot spring for a school trip, with an errand from Shigeru to pick up teacups from a near by pottery. While there he meets and helps a little fox spirit, who quickly grows attached to him.

Natsume goes to a dam and finds a town that had been submerged in water. Just then, Natsume gets possessed by a yokai and falls unconscious.

Natsume comes across an old ticket in Reiko's belongings and decides to go to the abandoned train station to see why she kept it. There, he meets a slow witted spirit named Santo, who was waiting for Reiko the entire time to go Kiriganuma, to see and make up with his friend, Mikuri, but the trip isn't as easy as it first seems…
