The initial episodes of Vandread shows Meia as a morose, silent crew of Nirvana. She rarely smiles (the couple of times could be counted in one hand), and only speaks when spoken too, unless she was reporting to the Captain or issuing orders. At the beginning it was shown that she despises men and was disgusted of herself when she needs help from the them. Along with the time, this hatred fades and she developed a strong bond with Hibiki based on the respect both of them had for each other.
Her unfeeling, cold persona was caused by her bitter past, and has caused her to avoid being close to someone in fear of being hurt. Thanks to the warm atmosphere in the Nirvana and the arrival of Kahlua and Misty, she softened up, and by the end of the series had changed into a kinder person, to her old team-mate's surprise.
As the Chief/Leader of Nirvana's Dread Team, she shoulder a heavy responsibility when in battle. She kept a close eye on the apprentice pilots (especially Dita) and held great concern to her team's safety (she even used her Dread as a decoy to lure the enemis away from Dita and Jura). Her quick thinking and sharp mind earned her the crew's respect.
Unknown to the others, except for Duerro, Meia suffers from claustrophobia.
In the past, her Fama abandoned her and her Ouma after getting involved in a public controversy. The two of them then lives under the blame and scrutiny of the public regarding of her Fama's mistake.
A short while later, a sudden system-failure in their living unit forced a mass evacution. This is when Meia lost her mother, who was left behind with the adults due to the capacity of the evacuation ships. She was left to witness an explosion which devoured her mother and the other adults who were left behind.
Since the incident, Meia was left alone to survive in the streets in her new unit. She then led a life in gangsters and street fights until the point where she met up with Magno Vivan, who recruited her as a pirate.
