She is a hacker who uses a technique called Aether Editing. By using a cassette labeled "LV.999" in her right gauntlet, she can transform by manifesting futuristic blue mechanical wings. Since using the cassette is powerful enough to be life-threatening, Elio—the leader of the Stellaron Hunters and a black cat who cannot speak human language—has confiscated it. Normally, she fights with an arm-gun that can switch between Blade Mode and Cannon Mode, large enough to bury her arm. She loves games and often mixes gaming terminology into her conversation.
