Natsume Yuujinchou: Nyanko-sensei to Hajimete no Otsukai

Separated from Takashi Natsume in the forest, Nyanko-sensei encounters two young siblings who have wandered away from home. Children are not among the great youkai's preferred responsibilities, and his first instinct is to escape the trouble. But dangerous spirits roam nearby, and even Nyanko-sensei cannot bring himself to abandon them. Escorting two energetic, curious children to safety proves to be a test of patience unlike any supernatural battle.
