Zatch Bell! is a Shonen Classic.

One hundred kids called "Mamodo" were sent to Earth to find the only human in the world who could read their spellbook, and that human would be their partner to assist them in battle.

The goal for most Mamodo is to defeat every other Mamodo, destroy their books, and be the last one standing. With an epic Mamodo free-for-all and the title of king on the line, it is a wonder why this classic anime was left in the past.
