This brings me to what the Movie version of Akio said to Anthy, "But, if you live on in the Outside World, you can only settle as princesses." T

Actually no. Movie-Akio refused to acknowledge the very existance of the Outside World - he said that if they go on, they'll only find the End of the World. He wanted Utena and Anthy to return to his world and be princesses, there. What the Shadowgirls said about the Outside World in the end was "In the Outside World you can make your own path", indicating that no classifications like Prince or Princess will tie those who travel there.

Ah! My mistake, gomen
