Natsume’s Book of Friends follows the story of high school student Takashi Natsume, who
possesses a strong ability to see spirits. He inherited this strange ability from his grandmother
and has had it as long as he can remember, which has made him introverted and shy. His life
changes one day when he receives a mysterious book that belonged to his now deceased
grandmother—the Book of Friends. Takashi soon discovers that the book is filled with the
names of countless spirits that were sealed away by his grandmother. Not only that—the
spirits who have their names written in the book must obey any order given by its owner. As a
result, the book becomes a prime target for all roaming spirits trying to gain control of the spirit
world. Believing it to be the right thing to do, Takashi takes it upon himself to return the names
of the spirits written in the book.
