Natsume's Book of Friends the Movie: Ephemeral Bond

Natsume continues to balance his life between the human world and the realm of Yokai when he unexpectedly meets Yuki, an old classmate, which brings back difficult memories related to a particular Yokai. At the same time, he becomes acquainted with Yorie Tsumura, a woman connected to the memories of a Yokai whose name Natsume had returned. Yorie, who now lives a quiet life with her son Mukuo, knows a lot about Reiko, Natsume's grandmother. Spending time with Yorie's family provides Natsume with comfort, but a mysterious Yokai has been appearing in their town. After investigating, a "Yokai seed" attached to Nyanko Sensei falls into the Fujiwaras' garden and grows overnight into a fruit tree. When Nyanko Sensei eats a fruit shaped like himself, he unexpectedly splits into three separate beings.
