Aura

Aura the Guillotine is a prominent, ancient demon and one of the Seven Sages of Destruction who served directly under the Demon King. Cloaked in an aura of chilling, detached elegance, she possesses striking features characterized by her distinct demonic horns, flowing purple hair styled in twin tails, and a seemingly youthful, delicate appearance that belies her monstrous nature. As a master of execution magic, she carries the Scales of Obedience, a legendary magical artifact used to cast her signature spell, Auserlese. This absolute magic weighs her soul's mana against that of her target, instantly and permanently enslaving whoever has the lesser magical energy. Having lived for over 500 years, Aura has meticulously amassed a colossal pool of raw mana, giving her supreme confidence in her superiority over shorter-lived species. To ensure her thralls can never break free through willpower, she ruthlessly decapitates her victims immediately after dominating them, commanding a massive, macabre legion of headless puppet warriors who feel no pain, fear, or exhaustion. This terrifying, undying army serves as her primary instrument of war, allowing her to siege entire human territories and wage relentless campaigns of terror across the northern lands without ever needing to engage in direct physical combat.
