Natsume Yuujinchou: Ishi Okoshi to Ayashiki Raihousha

Natsume has been busy, navigating between humans and Yokai when he coincidentally reunites with an old classmate, Yuki. It brings back painful memories of a certain Yokai. Meanwhile, Natsume also became acquainted with Yorie Tsumura, a woman in the memories of a Yokai whose name he had returned. Yorie knew much about Reiko, but now lived a peaceful life with her only son, Mukuo. Being with this family was comforting for Natsume, but apparently a mysterious Yokai has been lurking in their town. On the way back from investigating, a “Yokai seed” that had latched itself to Nyanko Sensei drops into the Fujiwaras’ garden and grows overnight into a fruit tree. When Nyanko Sensei eats a fruit that is somehow shaped like himself, he suddenly splits into three!

Takashi Natsume and his loyal feline protector Madara take a trip to Hitoyoshi Kuma, a peaceful area in Kumamoto. From admiring the Kaname Falls to relaxing at the Tsurukame hot spring, the duo unwind and take in the beautiful scenery throughout the eventful day.

Natsume has always been an outcast because he inherited his grandmother's ability to see yokai. After moving to his grandmother's hometown and accidentally releasing a yokai imprisoned in a Lucky Cat statue, he learns about his grandmother's "Book of Friends," which contains the names of the yokai she defeated, and allows its wielder to command the yokai named within. Since then, yokai now visit him on a daily basis, seeking to either get their names back or take possession of the Book of Friends.

Two special episodes bundled in the fourth and fifth volume of the Blu-ray/DVD.
