Gilbert durandal contacted Mia and hired her to impersonate Lax, thus improving his political status. After junius 7 crashed into the earth, Mia began to appease the people on the P.L.A.N.T When she accepted the job, Mia had plastic surgery, and her face looked exactly like Lax's. Although she doesn't look like Lax at all, many fans think she is Lax.
Mia is trained to be like Lax, but Mia regards Lax as a singer: singing some light music, dancing more, wearing sexy clothes and so on.
Realizing that Lux had more political influence than he did, Guibert used Mia as his political puppet to gain support for his policies. When she was respected, Mia was persuaded to play Lux, and everyone would love her very much and help promote peace. When most people can't tell Mia from Lux, Aslon Zara, kira yamato and other major figures in Aubrey know that she is not the real Lux, because Lux and most senior members of Aubrey's headquarters live on the Archangel. Gilbert durandal admitted to Aslan that Mia was a liar.
Although Lax was naive at first, Mia's personality was lively and silly. She is a little cheerful and naive, especially in front of Aslan. However, when she learned that Aslan had been framed as a traitor, she quickly warned Aslan.
In any case, playing the role of Lux may turn her into Lux, but it will also confuse her. When she first met Aslan, she immediately introduced herself as meer campbell and admitted that she was not Lax Cullen. When Aslan tried to persuade her to flee Gibraltar with herself, she refused, claiming that she was lax, preferring to be lax (this may also be an early sign of schizophrenia or a split personality). In the following story, Mia insists to Aslan and Lux that she is Lux. Mia was exposed to the public by Lux in a speech. After the incident, Guibert sent Mia and her bodyguard Sarah to Copernicus, an idle city in Moon City. Ironically, Archangel was chosen as Aubrey's second space fleet and landed in the moon city of Copernicus with Lux. Sarah informs Mia of the Archangel's appearance and tells her that Lux may be with the Archangel. Sarah suggested that Mia (the person who wrote to Lax) do something, and Mia, who was mentally unstable, accepted.
While Kira, Aslan and Mehring Hawke were shopping, Mia's red hello brought a note to Los Angeles International Airport, which read: "Miss Los Angeles International Airport, please help me! I will be killed! " . Aslan and Meiling thought it was a trap, but Lax decided to go anyway. She thinks Mia is asking for her help. The other three accompanied Lux to see Mia. Mia meets Lux and others in the empty amphitheater, and the assassination troops led by Sarah are waiting for an ambush. Mia threatened to shoot Los Angeles International Airport, but she was shot.
Aslan stopped it and shot the gun in Mia's hand. Mia insisted that she was Lax Cullen. Lax tried to calm Mia down and told her that even though she sounds like Lax, Mia and Lax are still two different people, and no one can replace anyone. Their dreams belong to them.
Lux accidentally entered Sarah's sight, but Kira's mechanical bird alerted Aslan to Sarah, and a firefight ensued. When Aslan killed most of the assassins, Sarah threw a Grenade, but it was shot back to Sarah by Kira and Meiling, and Sarah fell heavily.
When all the firemen were evacuated, fraga rushed Xiao, who didn't know the fire fighting equipment, to the coffin. When Lax took Shaw's hand, Kira invited Mia to run away with her, and Mia accepted. However, Sarah, who was dying, shot Lax and found that Mia tried to push Lax away, but was hit by a bullet. Aslan shot Sarah at once. Mia, who was in great pain, gave Lax a photo of herself before plastic surgery, apologized to Lax and begged her not to forget her songs and life. Tears welled up in Mia's eyes and she died on Lax's arm. Angry and sad, Aslan returned to the archangel with Mia's body, where she held a short and serious funeral.
