Takashi Natsume, the timid youkai expert and master of the Book of Friends, continues his journey towards self-understanding and acceptance with the help of friends both new and old.

Natsume, while briefly separated from Nyanko-sensei, is ambushed and kidnapped by a strange group of masked, monkey-like youkai, who have spirited him away to their forest as they desperately search for the Book of Friends. Realizing that his "servant" has been taken out from right under his nose, Nyanko-sensei enlists the help of Natsume's youkai friends and mounts a rescue operation. However, the forest of the monkey spirits holds many dangerous enemies, including the Matoba Clan, Natsume's old nemesis.

Stretching from the formidable hideout of the Matoba to Natsume's own childhood home, Natsume Yuujinchou Shi is a sweeping but familiar return to a world of danger and friendship, where Natsume will finally confront the demons of his own past.

Encouraged by her managers, rising pop star Mima takes on a recurring role on a popular TV show, when suddenly her handlers and collaborators begin turning up murdered.

Amid a rising crime rate, the Inter Solar System Police (ISSP) set up a legalized contract system, in which registered bounty hunters, also referred to as "Cowboys", chase criminals and bring them in alive in return for a reward.
