Zatch Bell! Mamodo Fury
Right after Zofis is sent back to the Mamodo World by the once again victorious Zatch Bell, a mysterious figure appears. The figure is a mamodo child who looks like Zatch, named Zeno, who claims to hate Zatch more than anything. The doppelgänger and his partner, Dufort prove to be tough for Kiyo and Zatch, and finally, Zeno declares that he will leave them alone for now, stating that he wants Zatch to "suffer" another "living nightmare" before finally defeating him. Zeno and Dufort leave, and although Zatch is initially worried about the "nightmare" his lookalike mentioned, Kiyo encourages him to become strong and that they will never give up. Zatch agrees, and the two proceed on, prepared for another adventure.
