Zatch Bell Vol. 3 - The Invincible Folgore

In this action-packed Japanese anime, the brilliant 14-year-old Kiyo is the victim of merciless teasing at school for his aloof and disdainful attitude. When Kiyo's archaeologist father finds a blond child named Zatch Bell, he sends Zatch to try to help Kiyo become more socially adept. However, the cute kid and his arcane red book hold a remarkable secret: Zatch is actually a mamodo, a race of childlike entities with magical powers. Every thousand years, the mamodo descend to Earth for a battle royal that determines who will be crowned king of the mamodo world. Now Kiyo must master the book and unleash Zatch's powers in time to confront the other human/mamodo duos that are springing up around them.
