Zatch Bell!

Penny's Revenge! Assassins on the Loose! (2x5)

Air date: May 02, 2004

Penny reveals that her three minions are a thousand-year Mamodos from the previous battle, to attack Kiyo and Zatch. Overpowered, Kiyo and Zatch lead them to a narrow alleyway and use "Bao Zakeruga", but it is nullified by the Mamodo's attacks. Penny begins to explain the origins of the thousand-year Mamodos. She explains that a Mamodo named "Stone Goren" turned the Mamodos and their books into stone. When Milord-Z freed them, he found a way to get humans to read their books. By controlling their minds and hearts to match the book's wavelength, the humans then are able to read the spells from the book. Penny orders the Mamodo to deliver a final attack, but they are saved by Tia and Megumi Oumi's "Seoshi".
