The Sixth Spell

During their fight against Dr. Riddles, Kiyo and Zatch launch their Sixth Spell, but they cannot identify its powers. Finally, the spell subsides and Dr. Riddles casts his own spell, which causes multiple Mini-Kidos to emerge and attack Kiyo and Zatch. Kiyo asks Zatch to remember what he thought about when they cast the Sixth Spell. Whatever it is, it might be the basis for the power of the spell. Zatch realizes his power and attacks the Mini-Kidos with speed, stopping another powerful attack.

Every thousand years, hundreds of Mamodos descend upon Earth to take part in an epic battle to be crowned "King of the Mamodo World." Each one possesses a book of spells that can be read only by a human. When a Mamodo teams up with a human partner and a spell is read out loud, the spell book unleashes incredible powers- but if their spell book is destroyed, the Mamodo disintegrates and returns to their world in defeat.
