Zatch Bell!

Attack of the Iron Army! (2x45)

:

Maestro tells his servant to call Brago in to talk. He tells Brago how in the In-between World, Mamodos with spell books are able to cast spells without their human partners. He then asks Brago to join him. Elsewhere Kiyo, Zatch, and Ponygon search for a way to return home, when they come upon an army. The army led by Kurogane, requests the three to surrender and be taken to Maestro. Kiyo refuses, and the three battle against the army. During the battle, Kiyo realizes the Mamodo army are unable to cast spells and that they all have iron armor. Kiyo then casts "Jikerdor" and defeats the army. Kurogane manages to resist the magnetic pull of "Jikerdor" and continues the battle. Zatch defeats Kurogane soon after. They learn that Maestro lives in the castle at the North, and they decide to head there. Brago meanwhile tests to see if spells could be cast without a human partner reading the spell. Realizing it to be true, Brago takes the book and leaves Sherry.
