Aurora also known as the demon Diablos, is a mysterious person from the distant past, regarded as the "Witch of Calamity" who plunged the world into chaos. At present, the eponymous "Cult of Diablos" is trying to harness her power for their own ends. Following the "Red Moon Incident", her spirit began residing within Claire Kagenō's body as a vessel. Aurora has a beautiful face with long black hair (violet in the anime), her eyes are a vivid shade of violet, and has a mole under the right side of her mouth. She was tall and slender as a beautiful woman with a good chest and good legs with pale skin are almost translucent. Aurora wears 2 half-shaped golden decorative earrings with a earrings drop in both ears, with a tied-up hairstyle of 3 large tails that reach down to her feet, being the one in the middle length and more collected than those of the other 2 sides. She wears a semi-purple black dress with gold accents, a long black robe coat that had long sleeves that reached her hands accented with a gold decorative silhouette that covered the back, and black high-heeled shoes. Her dress is generally looks like a veiled woman, leaving her medium neckline uncovered with a green jewels around the neck, with a golden-yellowish green jeweled silhouette on the right-side of the middle above the abdomen, attached to a long 2-layer skirt, which raised the front part a little slightly to cover the knees and dark purple heels. As a child, Aurora wore a long white robe. Due to Aurora's amnesia, little is known about her past or motives. She is playful, humorous, and seems to be fond of Cid Kagenō. She had lost most of her memories from centuries of isolation by the time the current day of the "Goddess's Trial" happened. However, it's revealed she retained a lot more memories than she lets on. While reviewing the past memories, she has shown disappointment and is probably apathetic towards her younger self. Following her freedom from the Sanctuary, she requests Cid to kill her. After having entered the body of Cid's sister, Claire Kagenō, she spends her time in an observant way and having fun watching Claire interact with other people, especially with other girls, who try to flirt with her brother. Aurora shows herself concerned with Claire when she gets into dangerous situations and has her sometimes to train her body so that she can use it to draw out and use more magical power, even if it is for a limited period of time. Aurora, on several occasions, hints to Claire about the true identity of her own brother, Cid and the things he really does, but does not tell her directly for certain reasons, which according to her, it is better for her not to say, and she replies to Claire not to risk so much and to trust more in that "person", since he has always been protecting her since she was little.
