Moto no Moto no Ana no Naka (2006)

Oni blood flows through Kiichi’s veins, and he has exceptional strength and a horn on his forehead as proof of that. He has never been outside the village - not even with his late mother - until a traveling librarian Mototaro comes with his little assistant Hana, and Kiichi decides to join them on their way to the book depositories in order to know more about his origin. Mototaro has the ability to draw living things from books and put them back. Soon an amamori (who train birds and traditionally protect the librarians) called Mori comes along. Protection is just what they need when several parties are trying to catch Kiichi because of an old tale.
