For those who don't know what I'm talking about:
"Crest of the Stars" is the first installment anime series based on a sci-fi novel series that is pretty famous in Japan. Jinto is a prince whose home planet was taken over by the Abh because his father handed it over in exchange for a place the empire. Now Jinto is being shipped off to get an Abh education. On his way to getting transported to his destination, he meets Lafiel, who happens to be the princess and heiress to the throne of the Abh empire. Quickly the two become friends, and are forced to rely upon each other when the Abh empire is plunged into war with the United Mankind.

When the women do emigrate, the men rebelled and overthrew the guards and captured Jinto. While this is occurring, an enemy fleet arrives, forcing Lafiel to abandon Jinto.
