In contrast to her sister who is cheerful and open, Meyrin is shy and somewhat closed off even from her own sister. Despite this she does maintain a friendly relationship with everyone on the ship but only seems to hang around her sister more than anyone else, however despite her closeness to her sister Meyrin carries somewhat of an inferiority complex to Lunamaria; this seen when Lunamaria is in the shower and Meyrin trys on her miniskirt and is annoyed when it doesn't fit her. Also like her sister she has a crush on Athrun Zala, however due to her shy nature she is unable to express herself.
Meyrin is the youngest member of the bridge crew, but she supervises the ship's mobile suits and communications. Her greatest asset is multi-tasking in tactical coordination and hacking systems. She was trained to delegate information between the bridge, the MS pilots, communications between Minerva crew members for tactical coordination, and their complex launching procedures with professional efficiency.
