Natsume's Book of Friends - S04

Takashi Natsume, the timid youkai expert and master of the Book of Friends, keeps moving toward understanding and accepting himself, with help from friends new and old. When Natsume is briefly apart from Nyanko-sensei, he is ambushed and taken by a strange group of masked, monkey-like youkai, who carry him off to their forest as they frantically search for the Book of Friends. Realizing his "servant" was snatched right out from under him, Nyanko-sensei gathers Natsume's youkai friends and launches a rescue. But the forest of the monkey spirits is full of dangerous foes, including the Matoba Clan, Natsume's longtime enemy. Reaching from the Matoba's imposing hideout to Natsume's own childhood home, Natsume's Book of Friends Season 4 is a wide-ranging but familiar return to a world of danger and friendship, where Natsume will finally face the demons of his past.
