Natsume Yuujinchou Roku

Takashi Natsume has grown more accustomed to the youkai drawn to the Book of Friends, the volume left by his grandmother Reiko containing names of spirits she defeated and bound to her. He still intends to return those names to their owners, but the book's power attracts both youkai and exorcists who would rather use it for themselves. Each encounter reveals more about Reiko and the lonely world she once inhabited, while Natsume slowly allows the people closest to him to see parts of his own life he has long hidden. Protecting the book becomes not only an inherited burden, but a path toward understanding his past and accepting who he wants beside him.
