Natsume's Book of Friends

Natsume's Book of Friends (Japanese: 夏目友人帳, Hepburn: Natsume Yūjin-chō) is a Japanese manga series written and illustrated by Yuki Midorikawa. It started in Hakusensha's shōjo manga magazine LaLa DX in June 2003, where it ran until April 2008; it has been serialized in LaLa since July 2007. Its chapters have been collected in 31 tankōbon volumes as of September 2024. The manga is licensed for English release in North America by Viz Media, which released the first volume in January 2010.
The series follows Takashi Natsume, an orphan boy in his late teens who can perceive and combat yōkai. One day, Takashi finds a very old notebook called the "Book of Friends", left by his late maternal grandmother Reiko Natsume, an exorcist who possessed strong spiritual powers. The notebook was used to bind dozens of powerful demonic spirits, both good and evil, to follow Reiko's every whim and desire if called upon. Takashi resolves to give back all the names in notebook; in the process, he joins forces with another feline/wolf-like spirit called Madara (nicknamed "Nyanko-sensei"), who knew Reiko when she was alive. Madara takes the form of an overweight cat and intends to take back the notebook after Takashi dies. Until then, he agrees to protect Takashi from the nefarious spirits who want to harm him for being the grandson of Reiko.
The series has been adapted into a series drama CDs. An anime television series adaptation, produced by Brain's Base (seasons 1–4) and Shuka (seasons 5 onwards), have been broadcast on TV Tokyo in 2008, 2009, 2011, 2012, 2016, 2017, and 2024. Two anime films, Natsume's Book of Friends the Movie and Natsume's Book of Friends: The Waking Rock and the Strange Visitor, were released in 2018 and 2021, respectively. The first four seasons of the anime were licensed by NIS America for a North American release in 2012 and released on home video in Japanese with English subtitles. The series has also been streamed by Crunchyroll, who produced an English dub in 2022.
By September 2023, the manga had over 16 million copies in circulation.
For as long as he can remember, Takashi Natsume has had the rare spiritual ability to see and commune with yōkai and ayakashi, inheriting the powers from his late maternal exorcist grandmother Reiko Natsume. This ability resulted in his having a lonely childhood, because children his age considered him strange. He had also been passed from one paternal relative to another. Upon her death at a young adult age, Reiko bequeathed to her grandson her "Book of Friends"—a book containing the names of hundreds of spirits she had bullied into servitude.
The Book of Friends is considered a highly prized item in the supernatural world, and such demons and spirits—both good and malicious—hunt Takashi constantly because of it. Takashi spends his time dissolving the contracts that Reiko created and releasing the various spirits that come to him. Malicious spirits, on the other hand, try to kill him to obtain possession of the book, which is where Madara (called "Nyanko-sensei" by Takashi) comes in. Madara serves as Takashi's bodyguard and spiritual advisor of sorts, even though he is ostensibly motivated by his own desire to possess the book once Takashi dies. He later begins to become more attached to Takashi, with the latter forming a similar bond with Madara (despite the latter's attempts to deny it).
Takashi also finds a good friend in an exorcist named Shuuichi Natori, who is also one of the very few humans who is capable of perceiving and taking down spirits via certain banishing or sealing spells, but also finds a dangerous adversary in Seiji Matoba, who has plans for Takashi to join him and his nefarious clan of exorcists. Takashi is determined to release all of the names before the conniving Matoba clan or other malicious spirits attempt to use it for their own gain as he tries to learn whatever he can about his maternal grandmother and the strong spiritual connection they share.
Midorikawa created Natsume's Book of Friends as an episodic serial for a manga magazine published every two months, so that each chapter was a story that could be read on its own. As the result of earlier writing a ghost story that an editor made her revise to include more romance than she initially wanted, Midorikawa specifically created Natsume's Book of Friends as a supernatural story with less romance, containing supernatural elements that stir readers' imaginations the way stories about yōkai and local gods stirred hers while growing up in a rural area. For the basic story, she wanted to write about a boy and his non-human teacher, and include the incongruous element of the boy's grandmother in a school uniform.
This was the first series Midorikawa wrote in which the protagonist was also the central character. Midorikawa claimed that as a character, Takashi is almost as bad as herself at expressing his thoughts, which caused her to use more interior monologue than she was comfortable with for a male character.
Written and illustrated by Yuki Midorikawa, Natsume's Book of Friends was first published in Hakusensha's shōjo manga magazine LaLa DX from June 10, 2003, to April 10, 2008; it has been serialized in the monthly sister magazine LaLa since July 24, 2007.
