Aura the Undying is a powerful demon and one of the Seven Sages of Destruction serving the Demon King in Sousou no Frieren. Known for her immense mana and the ability to control any being with weaker mana via her spell Auserlesene, she commands an army of demons. Her arrogance leads to her downfall when she underestimates Frieren's mana concealment spell during their confrontation, resulting in her soul being offered to the demon Zartlach. Aura possesses pale skin, pink hair, horns, and wears revealing attire befitting her status as a formidable antagonist.
