Tamami, a young schoolgirl, counts her steps through a forest, following instructions on a piece of paper. She stops to take a break and falls asleep but is awakened by an odd talking cat. Through meeting the cat and his human partner, Natsume, she learns that the forest has its own separate world from the contemporary, where one can see things otherwise invisible. Putting her trust in the duo, Tamami tells them about the story of how she helped a white owl that reappeared in her dreams to lead her back inside the bizarre forest.
