List of Characters

Chukyuu (A and B) are recurring characters for the series, Natsume's Book of Friends.

Natsume helps them discover the identity of the "youkai exterminator" in Yatsuhara. Afterwards, they become his informants and supporters.


One Chukyuu is an ox-like youkai while the other is a one-eyed youkai with one horn.

Both wear grey kimonos with a black Japanese-style coat over it.


The two are peaceful in general, supporting "Natsume-sama" with his tasks when asked.

The one-eyed youkai is usually the one who does the talking as the ox-like youkai follows and gives his bits of information.

When their forest, the Yatsuhara Field, was threatened by Tanuma's father, they came and asked for Natsume's help, begging him to get rid of the priest that was exorcising the youkai in the surrounding areas of the temple. Later on, they become Natsume's loyal followers.

In episode eleven of season five, they show Natsume Mitsubatake's Shiraki flowers. When he gets sick, they ask Ootsuno for medicine to help him and end up working for it, only to learn that the medicine doesn't work on humans. Later, they collect flowers on the mountain to give to Natsume as a gift but he visits and thanks them for the medicine. They sprinkle the plucked flowers down on him and Madara and note that even though the flowers' petals will soon fall, they cannot tear their eyes away.

Moreover, they are also the founding members of "The Dog's Circle" - a ragtag band of trustworthy youkai who are loyal to Natsume Takashi that constantly support and believe in him. Other members include Hinoe, Madara, and Misuzu. The Dog's Circle also gathers every night for a drinking party.
