Sara Aston, Millerna

ミラーナ・サラ・アストン

The third princess of the kingdom of Asturia, who is in love with Allen Schezar, although she is betrothed to the merchant prince Dryden Fassa. Millerna's ambition was once to become a doctor, but she was forced to abandon her medical studies by her second sister, Eries.
Her eldest sister, Marlene, is deceased; she was the wife of Duke Freid and the mother of Allen's son, Chid. Millerna later runs away from Asturia to join Van's troupe and fulfill her dreams. She is upset by her engagement to Dryden, but gradually comes to appreciate her fiancé's good qualities. At the end of the series, however, they separate on good terms, with Dryden saying: "I will come back when I'm more deserving of you." Millerna then realizes that she can't depend on others to make her happy.
In the 1994 manga, Millerna plays a similar role. As princess of Asturia, she is engaged to Allen, and struggles to choose between complying with Zaibach for the sake of protecting the people from the threat, or siding with Allen, risking her people getting drawn into the war.
