Millerna Sara Aston is a supporting character in the film Escaflowne: The Movie. She is the third princess of the kingdom of Asturia. In this darker retelling of the story, Millerna undergoes a notable shift in personality: whereas she is typically reserved and well‑mannered in the original series, the film presents her as more aggressive and assertive. Her appearance and clothing are also redesigned to reflect this change. Within the film’s plot, Millerna plays a minor role. She travels alongside the knight Allen Schezar, supporting his efforts against the Black Dragon Clan. Her key relationship is with Allen, toward whom she harbors strong feelings. The film does not elaborate on her medical aspirations or betrothal to Dryden Fassa, as those elements belong primarily to the television series. Millerna’s development in the movie is limited, but her shift from a reserved princess to a more combative participant in the conflict marks her primary character arc. She does not exhibit any special abilities beyond her royal status and willingness to engage in the struggle.
