As the first delicate snowflake touches the cold ground, Nyanko-sensei dozes on his hot-water bottle next to Takashi Natsume. While his aunt prepares a warm dinner, Natsume takes a walk, welcoming the snow and the chilly weather. However, his peaceful promenade is disturbed by a white, fluffy snowman yokai with perturbing black eyes, searching for something warm and sparkly. With no further information, Natsume sets off to help find what the spirit desires.
