She is one of the Seven Sages of Destruction directly serving the Demon King. Using her signature magic, Auserlese, she weighs the mana of her opponent's soul as well as her own on her Scales of Obedience, granting the soul with more mana complete control over the other's body. Aura is, as a demon, an "articulate monster" who is individualistic and harbors no sense of empathy. Even though she has her executioners as subordinates, she was not distressed in the slightest to learn of their demise.
