Cat-Eyed Boy is the son of Nekomata, a cat demon, and a human mother. Half-demon, half-human, he is shunned by both worlds. He is raised by a foster mother, Miya, who has to beg for food, and he becomes a mischievous nuisance to the village he lives in. When a demon called Nadare-Maneki (the Landslide Summoner) attacks, Cat-Eyed Boy must try to save himself and his foster mother from its relentless attacks.
