Natsume Yuujinchou: Itsuka Yuki no Hi ni

As the first snow settles over the countryside, Takashi Natsume goes out to enjoy the quiet winter air while Nyanko-sensei stays warm at home. His walk is interrupted by a small white yokai shaped almost like a snowman, which desperately searches for something it can describe only as warm and sparkling.

Natsume agrees to help despite having little idea what the spirit wants. Their gentle search through the snow becomes another encounter with the fragile desires yokai leave behind, and with the warmth that can exist in a brief connection between two beings who may never meet again.
