Early life
Alia was evidently born in the world of the Gamma at some point by the mid-19th century at the latest, the secondborn child and only daughter of the Emperor Adonis and his wife. She was joined by two younger brothers, Adel and Alain; and an older brother, Argos; before their mother died.

Ghost
Alia found two humans, Makoto and Kanon Fukami, soon after the two were sucked into the Gamma World. She was shown bringing them to an unknown location, running into her brother Alain along the way. When Alain coldly ignored the humans, she told them not to mind him and to keep going. Alia subsequently assured the siblings that they didn't need to worry anymore and that they could live with her.

She first appears in the present day alongside her younger brothers and her father, Adonis, as they are met by the Gamma magistrate, Edith, who had requested an audience with the royal family. Later, Alain confided with her his confusion with his father's advice to follow his heart. Alia stated that Adonis must have his reasons, before asking Alain about Makoto and Kanon, wondering if they could meet again. She seemed distraught when Alain dismissed the idea, saying that Specter and Kanon could never return. Adel informs Alia that their father are assassinated by Alain. However, Alia disbelief that Alain would never do something on their father. In the same time, Makoto visits Alia for her kindness on raising him and Kanon. As her debt, Makoto offers Alia to visit human world, the Earth. Despite Makoto's offer, Alia cannot leave her homeworld due to being needed, while also informing Makoto that Alain is being framed by Adel for assassinating Adonis.

She noticed that her father was never being killed due the former was in his Gamma Eyecon body. Alia soon found her father being kept hidden, but Adel warned her to stay back, as he is now in his original human body and being held a prisoner in a barrier that could have hurt her by Adel, learning that Adel is indeed lying to her and their people all along for his regime. Without any option, she must follows Adel's play until the time has come to get a reinforcements like from Alain.

Once Alain finally arrived on time with a reinforcement, Alia reveals to her younger brother that it was a set-up by their brother, Adel on making their homeworld into imperfect world/dystopia, not a perfect world/utopia they tried to achieved.

After she learns from Takeru that her father was killed at the hands of his own son, Adel, leaving Alain to become broken, Alia defends both Takeru and a broken Alain from Adel's army, asking Takeru to take care of Alain for her before he left, as Takeru already kept his promise to Makoto to begin with, and thanks her for her similar advice and promises.

Wondering what was happening to Adel, Alia confronted Edith, asking what he was trying to do. Edith replied simply that he wanted to create a utopia.

She later confronts Adel, Gammaizer Climate and Gammaizer Planet as Dark Necrom P. But her power is no match for that of the Gammaizers and she's forced to cancel her transformation which causes her Gamma body to be destroyed leaving the shattered remains of her Eyecon to be absorbed by Gammaizer Magnetic Blade. After she awakens from her stasis tube, she is held captive by Adel.

Alia witnessed Emperor Adel begin his transformation into the core of the Demia Project, advising her younger brother that he could still turn away from this only to be silenced by Adel who rendered her unconsciousness with his power.

Personality
Unlike her brothers, Alia does not have an inherent hatred of humanity. She showed genuine kindness to Makoto and Kanon, and remember them as fondly as they do her. Alain seems to have a better relationship with her than with Adel, as he went to her for advice on something their father said. This is further evident as she begged Adel to stop with his plans, much to it falling on his deaf ears.
