Zatch Bell!

Selfish Penny's Goodbye (2x32)

:

With Penny's water spells combined with Zatch's lightning spells, they are able to gain the advantage against Delmolt. It is revealed that Delmot was only using his weak spells, and when he uses a stronger spell, he knocks Kiyo, Zatch, Sunbeam and Ponygon out. Penny battles Delmolt and Byonko regrets assisting Zatch while Alvin is unable to cast spells. Alvin reveals that he purposely did not cast spells because Byonko was sided with the evil Zofis. Alvin tells Byonko he will help him fight Delmolt. Tia uses "Saifogeo" to heal the unconscious members. Delmolt uses an attack that causes Byonko's book to burn, and Penny's book catches fire. Penny manages to destroy the moonstone but sacrifices her pigtails in the process. As she is about to be killed by Delmolt, Zatch saves her. Penny asks Zatch and his friends to befriend Byonko, and she says that she will be okay. As Penny returns to the Mamodo world, Zatch tells her that she and Byonko are their friends too.
