Millia

Millia (ミリア) is the daughter of the late Viscount Grease. Ever since contracting the Demon Possession, she becomes a research experimental subject while her father working for the Cult of Diablos that he tries to cure her. After her encounter with Alpha, she is retrieved by the Cult of Diablos and turned into a more potent weapon. She is then cured and defected to Shadow Garden as No. 711.

Appearance
Millia is a beautiful young girl. She has gray hair similar to her father's. She wears a dress and two bows, one on her head while the other tied behind her back. She also carried a teddy bear. She has a petite build, resembling a thirteen-year-old girl.

The Beginning of a Cursed Life
Millia is the daughter of Viscount Grease and has a wonderful life with her father. Millia also enrolled in the Midgar Royal Spellsword Academy.

At some point in time, Millia was afflicted with Demon Possession much to her father's horror. This caught the attention of the Cult of Diablos who abducted Millia and forced her father to work for them, in exchange for not only her safe return to him but also the means to purge the curse from her body.

Eventually, Grease reluctantly joined the Cult and was forced to go along with their wishes in the hope that her disease symptoms could be cured. But tragically, Grease was killed by Shadow Garden and Millia remained under the mercy of the Cult.

Princess Alexia's Kidnapping
About 2 years later, Millia still becomes a test subject for the Cult and was treated as a failed experiment in which her body was intentionally demonized until become heavily mutated due to Demon Possession, that she barely looks human at all. Millia was kept in a laboratory hidden at Midgar Kingdom under the royal capital, where she was subjected to horrendous experiments and constantly abused by a scientist that work for the Cult. On that time, Millia was imprisoned next to the Second Princess Alexia Midgar, who had been kidnapped by Zenon Griffey.

When Millia later hears the commotion made by Shadow Garden, the scientist who has tormented her for a long time tries to inject Millia with a prototype serum that can increase her powers which she uses to kill the scientist. Before escaping, Millia freed her fellow captive, Alexia by destroying the Magic Sealing Chains on her limbs.

Later, the now monstrous Millia rampaged across the royal capital, eventually being confronted by First Princess Iris Midgar and her knights. Despite receiving several attacks, she was able to survive and continued fighting. Alpha arrived and cured Millia, freeing her from her Demonic Possession and allowing her to rest.

Powers & Abilities
During her rampage across Midgar Kingdom's capital, the mutated Millia exhibits superhuman strength and razor-sharp claws for offensive purposes. Her most unique on Millia's demonized state is a high regenerative ability, allowing her to survive even from multiple fatal slashes. But her overwhelming power is no match for Iris Midgar until she eventually returned to her normal state by Alpha. After the Cult retrieves her body, they performed numerous experiments transforming Millia into the "Cult's strongest human weapon", a huge monster with numerous amounts of tentacles that possess great strength and magic. After Shadow defeats and heals her, she reverts back into her human body, hence losing her monstrous appendages. After training in Shadow Garden for a brief period, she is noted to be a prodigy in swordsmanship but struggles to remain calm initially.
