Usako, daughter of the incompetent Emperor Lei Lei, more or less runs things in Little Tokyo. Her one desire is that she always get her way, and people are usually more than willing to do so, because at even the slightest accidental slip, she is more than ready to send anyone to Prisoner Island. Sometimes, Usako gets bored and decides to do some wandering around (and the attendants can't do a thing about it), which usually provides the Big Cheese with a chance at kidnapping and the Pizza Cats a major headache trying to keep her safe.
