Courage, friendship, and adventure meet when high school student Kiyo and Zatch Bell, a strange boy with magical powers, team up to win the ultimate battle! There's a new mamodo on the scene...and he has bunny ears. Momon is a somewhat cowardly character who's been able to avoid competing in the battle to become king thanks to his radar-like abilities that allow him to pinpoint other mamodo's locations. But when he uses his skills to catch the ever-ready-to-strangle-someone Tia off guard, he risks earning himself a fast trip to the hospital. What's a naughty bunny in the big city to do?
