The third princess of Asturia is in love with Allen Schezar but has been betrothed to the merchant prince Dryden Fassa. Her ambition was once to become a doctor, but was forced to give it up by her second sister Eries. Millerna's eldest sister Marlene was deceased and had married Duke Freid and given birth to Allens son Chid. She later left Asturia to join Van's troupe in order to fulfill her dreams. Initially, she is unhappy with her engagement to Dryden but eventually comes to appreciate his qualities. Despite this, they separate on good terms at the end of the series, with Dryden saying "I will come back when I am more deserving of you." This realization causes Millerna to understand that she cannot rely on others to make her happy.
