Kiyomaro Takamine, a depressed teenager, is suddenly given a little demon named Zatch Bell to take care of. Little does he know that Zatch is embroiled into an intense fight to see who is the ruler of the demon world. All of the demons have to pick a master on Earth and duke it out with other demons until one survives. Through their many battles, Kiyomaro learns the importance of friendship and courage.
The English release was edited, removing things like blood and nudity with Zatch wearing boxers instead of being fully naked. The uncut Japanese version of the series has never seen an official English release.
