Millia Rage

Millia Rage (ミリア＝レイジ Miria Reiji?) is a retired assassin, a character introduced within the Guilty Gear fighting game series. Millia participated in the first game of the series, Guilty Gear: The Missing Link, as well as every game thereafter. Easily noticeable by her long, "wild" hair and attractive nature, Millia is a favorite among fans of the series. Her weapon of choice appears to be her own hair, which is prehensile and able to change its size and shape.

Story
Background
Born of Russian descent, Millia lost both of her parents at an early age. She was thereafter adopted into a nearby Assassin Syndicate, where she practiced in the art of Hi-Deigokutsuipou, or the "Six Forbidden Magics". Using the Sixth Hi-Deigokutsuipou, "Angra", Millia's hair gained the abilities she currently possesses. Zato-1 practiced a similar technique, the Fifth Forbidden Magic, "Shokusei Kagejin", by sacrificing his sense of sight.
Due to Zato-1's rise in power within the Guild, Millia betrayed her "comrade", sealing him within a dimensional portal. Millia abandoned the Guild shortly thereafter, finding no comfort in the cruel ways of an assassin. The Guild leader eventually escaped, enraged at Millia's actions, leading to an overall hatred of women.

Guilty Gear: The Missing Link
Upon hearing of Zato-1's escape from the dimensional prison, Millia uses the Second Holy Order's Fighting Tournament as a method of tracking down Zato, determined to end his life once and for all. Manipulated much like the rest of the cast, the bloodshed from the Tournament releases Justice from her slumber. However, she is promptly destroyed by none other than Sol Badguy.

Guilty Gear X: By Your Side
Still in search of Zato-1, Millia hears mention of a Gear with free-will. Panicked countries establish another "tournament", with a prize of 500,000 World Dollars to he who captures, dead or alive, the aforementioned Gear. Rage uses this as yet another chance to find Zato. Canonically, the former assassin finally finds Zato, seemingly ending his life. Unknown to her, Eddie takes control of Zato's body thereafter, having been slowly gaining control over Zato since the bonding with its master.

Guilty Gear XX: The Midnight Carnival
After the "death" of Commander Gear Dizzy, as well as Zato-1, Millia continued living in her familiar solitude. However, it was not long before she received sightings of a being similar to that of Zato's Forbidden Beast, Eddie. Encountering many familiar, as well as new, faces along the way, Millia once again confronts Eddie.
In XX, Slayer "reveals" to Millia that her hair is of the same origins as Eddie, though Millia replies that "she knows this better than anybody."

Relationships
Comrades during her stay in the Assassin Syndicate, Millia was the one responsible for Zato's dimensional imprisonment. One of the major relationships throughout the story, Millia's hatred for Zato-1, and thereafter Eddie, will not cease until his utter demise.
In Guilty Gear X, as well as one battle during the story mode of Guilty Gear XX, Millia and Zato have a special theme song for the matchup, similar to the theme used when Sol Badguy faces Ky Kiske. This theme is called "Still In The Dark".

Venom
Venom is the comrade of Zato-1. Taken into the Assassin Syndicate by none other than Zato himself, Venom holds him in the highest of regards, respect, and honor. Moreover, as stated in the latest drama CD, Knight of Knives, Venom is indeed homosexual. Such would help to explain the extent of Venom's feelings for Zato, as they seemed more than platonic.
Millia observes Venom as a "lapdog" and nuisance, blinded by emotion and his love for Zato. Venom and Millia battle occasionally, though neither has yet to best the other. Venom blames Millia for the death of Zato, fueling his hatred for her even further.

Musical References
Millia Rage is named after the band Meliah Rage. Her Iron Savior, Emerald Rain, Silent Force, Winger, and Iron Maiden attacks are all named after bands. Her Bad Moon attack is named for Creedence Clearwater Revival's song "Bad Moon Rising". In her background story, Millia undergoes the 6th forbidden magic, "Angra", to gain control of her hair as a weapon, and this ritual bears the same name as the Brazilian heavy metal band Angra.
