For all of Takashi Natsume's life, he's been able to see spirits, or "ayakashi," thanks to a power he inherited from Reiko, his grandmother. When Reiko's end draws near, she hands her Book of Friends over to Takashi. This Book contains all sorts of contracts that Reiko had made, in her favor, between herself and a multitude of spirits. Due to the Book's nature and history, Takashi is constantly harangued by spirits by merit of being its new owner.

While Takashi's grandmother spent time binding spirits to contracts, Takashi seeks out ways of dissolving each one in both penance and a genuine desire to help the spirits. As some of these spirits are rather violent and homicidal toward Takashi, the cat-like spirit Madara appears. Madara, whom Takashi affectionately refers to as Nyanko-sensei, decides to protect and aid Takashi, while also seeking ownership of the Book for his own purposes.
