Proclaiming herself as Zatch's girlfriend, Patie had been in love with him since discovering him fishing in a private beach in the Mamodo World, ultimately trying any means possible merely to interact with him. Upon arriving in the human world, she made partners with Uri, a poor man trying to get food for his family under one condition: she would help him out in any way possible as long as he helped her find Zatch. Yet when she finally tracks Zatch down to Japan, Penny discovers the hard way about Zatch's lost memories, going absolutely berserk and forcing herself to fight him either to make him remember their (one-sided) love or to eliminate him from the tournament.
