...So that's why... I seem to recall... The G... Gear Project... Long, long ago... ...!?... That's right... Heh heh. H... How could I have forgotten you? If only if we could have talked one last time... Just the three of us...
Evil...? How dare you call me evil!? ...I fight for my own existence. No more, no less... .... ...Look at my body. I was created by humans to kill humans. ...I'm a weapon. Yet, the same humans that created me never thought about mind, or soul. I'd have been used as a tool... and if I refused, I'd have been dismantled! Ask yourself... Can you truly blame me? I was born into this world as a slave... And now you're here to destroy me. I know humans loathe me violently... and always will. I could do nothing but live on, if for no other reason than to scorn my creators! But what do you think I've been living FOR? My duty. My assigned role! I was created to kill, and so I do. It's justice!
Justice is a major antagonist in the Guilty Gear series. Created by That Man, Justice is the first "complete" Gear with free will and with the power to control all of her own kind. She was the instigator of the Crusades, a hundred-year war against humanity, until she was finally sealed by the Sacred Order of Holy Knights.
In 2180, the United Nations decides to reform the Holy Order, fearing for Justice's revival, and hosts the Second Holy Order Selection Tournament—a farce orchestrated by the Conclave to take control of Justice. During the event, Justice is freed from her prison by Testament thanks to the blood shed druing the matches. She immediately fights the contestants, plus Baiken, until she is ultimately destroyed by Sol Badguy. As she dies, she seems to regain her memories and wishes that the three of them could have talked one last time. It is unclear whether or not Sol actually realizes that Justice is Aria, but he vows revenge on That Man for everything he has done.

Justice's moves, Michael Sword and Michael Blade, are likely references to the archangel.
Due to a mistranslation in the original Guilty Gear game, her male voice actor and the blue ischium on her armor between her legs, it was previously believed that Justice was male, though in the original Japanese script, she was never referred to with any gender-specific pronouns.
Justice is the only character that can air dash from one end of a stage to the other.
In the original Guilty Gear, Justice had no respect action; she simply froze momentarily.
Justice's Saperia Trance from Λ Core Plus somehow has its sound effect removed.
Curiously, she shares this move with Valentine, who uses it after transforming into her Gear-like form.
Justice's role as the feared commander of all Gears hearkens to the idea of an evil overlord or demon lord in RPG/European Medieval fantasy; her mechanical and technologically advanced features, being Black Technology in-world, also draws upon the idea of said villains using forbidden and forsaken evil powers beyond common knowledge for their advantage.
