Her Majesty Princess Elza Bittencourt von Ferretous
Born out of wedlock, Elza is actually the elder sibling to Elzo the VIIIth. Except, she was snubbed as the legitimate heir to the throne when Elzo was born, despite the fact that according to a lot of people she is much more worthy of the position. She was kidnapped by Iron-Hand Gareth during the Dark Lord's assault on Bittonia. The scoundrel!
But apparently, she actually wasn't. And is still out there, somewhere.
