Natsume's Book of Friends Vol. 8 (manga)

Nyanko Sensei is recovering after being wounded in the last yokai incident, so Takashi is on his own when he accidentally releases a yokai right before the school festival. With new friends and his ever-strengthening relationship with the Fujiwaras, Takashi has more reasons than ever to keep the supernatural at bay. But does he stand a chance without Nyanko Sensei's power to back him up?
