Natsume’s Book Of Friends Vol. 6

Takashi Natsume, a boy who can see spirits, stumbles upon something interesting among his grandmother Reiko’s possessions: Her Book of Friends, which holds the names of all the yokai she forced into servitude! Accompanied by the yokai Madara, soon nicknamed Nyanko-sensei, he sets out to return the names to their rightful owners.
In Vol. 6, Takashi rescues Kai, a young boy he found locked up in a box at an abandoned building. Why are the yokai and Natori after him? This Japanese edition of Yuki Midorikawa’s popular manga contains chapters 20 to 22 along with specials 5 and 6.
