The anime tells an original story based on Yuki Midorikawa’s Natsume’s Book of Friends (Natsume Yūjin-Chō) manga.
Amazon Japan is listing the November issue of Hakusensha’s LaLa magazine with a cover image that states that Yuki Midorikawa’s Natsume’s Book of Friends (Natsume Yūjin-Chō) manga is getting a theatrical anime with limited screenings in early spring 2021.
The anime seasons and Midorikawa’s original manga revolve around Natsume, a boy who has been able to see yōkai since he was little.
Midorikawa’s Natsume’s Book of Friends manga debuted in Hakusensha’s LaLa DX magazine in June 2003.
