With his horned head and pointed ears, young Kiichi resembles a demon. When his mother dies, he is ostracized from his village. Alone and with no clue to his true origin, he meets Mototaro, a traveling "Library Man" who goes from town to town, lending out books. When Kiichi spies some magical creatures literally jumping out of the pages of one of these books, he thinks he may be on the way to finding out where he came from. Mototaro and Hana, his young assistant, agree to let Kiichi accompany them. Together, they will encounter strange creatures and adventures while Kiichi tries to find his place in the world.
