Natsume's Book of Friends Season 6

Takashi Natsume has come to accept that the Book of Friends will keep drawing him into the world of youkai. The notebook holds the names of spirits his grandmother, Reiko Natsume, bound through contracts, and each new encounter deepens Natsume’s understanding of the youkai around him, of Reiko’s past, and of his own place between both worlds.

Because the Book of Friends can be used to command youkai, it attracts unwanted attention from spirits and exorcists alike. While Natsume longs for an ordinary, peaceful routine, the book’s pull continually interrupts his days, pushing him to learn more about its origins and the wider world of exorcism—and to gradually rely on the people willing to stand beside him.
