The story follows Kiyo Takamine, a 14-year-old boy in junior high school. His father, Seitaro Takamine, discovers an unconscious child named Zatch Bell while in a forest in England, and sends Zatch to live with Kiyo. Unlike the other Mamodo, Zatch lost his memory of the Mamodo world. Kiyo learns about the spell book when he reads a spell causing Zatch to fire lightning from his mouth (the spell is mentioned in the first episode). As Kiyo and Zatch begin to encounter different Mamodos and learn more about the Mamodo battles, they discover that there are those who do not wish to fight and there are those who fight for the wrong reasons.
