Aura

Aura (アウラ), also known as Aura the Guillotine (断頭台のアウラ) is one of the Seven Sages of Destruction directly serving the Demon King. Using her signature magic, Azerilyse (Subjugation magic), she weighs the mana of her opponent's soul as well as hers own on her magic scales, which grants the soul with more mana complete control over the loser's body. Aura became a Sage of Destruction more than 500 years ago and built an army out of the people whom she subjugated with her magic. She is famous for decapitating every person she successfully controlled, after finding out that a person with sufficient willpower could partially defy her magic; this tendency granted her the title of "Guillotine". After her retreat from the battle against Himmel and the defeat of the Demon King, Aura had remained in hiding until the Hero Himmel had passed away. After which, she reappeared and began to wage a war in order to take over Graf Granat's domain.

Personality
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. Typical of her race, she has strong confidence in the superiority of her magic and seems to enjoy battles where she thinks she has the upper hand. However, Aura has also shown to be a cautious person. When she is up against enemies whom she could not beat, such as the Hero Party, she will opt to choose to retreat instead of trying to face them head-on. This tendency has probably contributed to her survival when the Demon King was defeated.

Appearance
Aura has magenta hair that reaches to the middle of her back. Her hair is gathered in two pigtails tied at the shoulder. The remaining hair in the pigtails is sectioned off into three braids. Aura has dark blue eyes and two light brown horns protruding through her hair. She wears a dark, sleeveless bodice with white trimmings that has a cutout at her navel and a ruffled white skirt underneath. A magenta skirt tail is fastened at her waist with gold buttons, complementing the golden accessories at her neck. Her opera gloves are the same color as her bodice and wrap around her upper arm in a series of threads, and her boots are striped and reach mid thigh.

History
After the Demon King was defeated, Aura disappeared without a trace but showed up in the Northern Lands again after Himmel's death. She has been in a bitter war with the humans there since then. Seemingly tired of war, she sends three of her executioners as messengers to sue for peace by the time Frieren's Party arrives in Graf Granat's Domain.

Abilities

 * Auserlese (Spell of Obedience): Aura's special magic. It manifests as a pair of Scales with which she weighs her and her target's souls. If Aura possesses more mana than her enemy, she can control their body forever using her Scales of Obedience. However, the subordination can be broken by someone with an indomitable will. Aura foregoes this problem by simply beheading the people she controls.


 * Aura's magic is incredibly powerful, though it does have very high risk. As the soul with more mana can permanently take control of the loser's body, Aura puts her own life on the line when she uses her Scales of Obedience. If she ever makes a mistake in judging the amount of mana her opponent has, she will stand to lose everything.

Trivia

 * Like all demons, she cannot comprehend the fact that an extremely powerful mage exists who would limit their mana their entire life just to deceive demons. This leads to Aura losing to her own submission magic, giving Frieren free reign over Aura's body.
