Assisted by his old comrades and newfound allies, Takashi Natsume - the expert on youkai and holder of the Book of Friends - is on a journey towards self-awareness and self-acceptance. While his associates play a role, his greatest support comes from the grumpy wolf spirit, Madara; he loves sake and food and goes to great lengths to protect Takashi, whether that means transforming into a pudgy feline or not. However, Takashi's world is turned upside down when he is taken away and held hostage in a woodland lair by face-obscured, simian youkai. Nyanko-sensei puts together a daring plan to rescue his dear master with the help of Takashi's youkai squad, but their mission is fraught with danger, including the nefarious Matoba Clan, Takashi's arch-enemies. Natsume Yuujinchou Shi takes us from the Matoba Clan's massive stronghold to Takashi's childhood home, offering a familiar yet thrilling backdrop of danger and camaraderie. For Takashi, it's an opportunity to fight his inner demons and win.
