Beside Takashi Natsume, Nyanko-sensei takes a nap on a hot-water bottle as the first delica te snowflake touches the frigid ground. Meanwhile, Natsume's aunt prepares a comforting meal while he takes a leisurely stroll in the frosty weather, enjoying the snowfall. However, his peaceful walk is interrupted by a yokai snowman with eerie black eyes. The fuzzy creature seeks something warm and shiny, and without hesitation, Natsume sets out to help the spirit find what it's looking for.
