The youngest daughter of Duke Medaiyu, the monarch installed by the London IMA to serve as the ruler of the Siberian Domepolis, Princess Ana was kidnapped, albeit willingly, by Gain and Gainer just prior to launching their great Exodus to Yapan. While technically, Ana is considered to be a hostage, she is far from treated like one, having pretty much free reign to do as she likes aboard the city units in the Exodus convoy. Due to this, she seems to be having a lot of fun being a hostage, despite the constant danger that she and her new friends find themselves facing.
