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 to Cid Kagenō

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.

Powers & Abilities
Although the true extent of Aurora's abilities remains unknown, it is implied that her strength rivals Shadow since the Sanctuary summoned a projection of her to face him as an "equal" opponent and Nelson believed that it was already strong enough to defeat him. While said projection was ultimately defeated, it kept Shadow on the defensive for most of their fight and Cid himself noted that it paled in comparison to the real deal. Whilst possessing Claire's body, though still unable to use her full strength, she easily overwhelmed Elisabeth.

Physical Prowess
Although her full prowess in this field remains unknown, Aurora seems to be deficient at hand-to-hand combat, although this was only seen with her projection. While fighting alongside Cid during the test at the Sanctuary, she could only stomp on her enemies with her heels.

On the other hand, Aurora is skilled with medium-range weapons, like polearms, though it is speculated that she uses magic to make it easier. Her primary weapon appears to be a scythe, using one in both her projection's fight against Shadow and again later while possessing Claire's body.

Despite Aurora being of the most famous mages in history, she is still physically weak. Cid notes that she's not particularly good with a sword.

Supernatural/Demonic Biology
Due to the multiple magical experiments that were carried out on Aurora since she was a child, by introducing all kinds of chemical substances and demonic properties into her, Aurora developed both a physical and a magical biology that gave her all great powers that gave her the title of "the witch of Ruin", the woman who caused chaos in the world.

After becoming the Demon King Diabolos, his biology became demonic with great magical vitality, that even if his limbs were severed, they still lived indefinitely, containing a part of the consciousness and soul of what Aurora once was, attacking anyone nearby at hostility level, and continuing to regenerate their flesh and demon cells, as long as they were in low numbers.

Ancient Mystic Knowledge
Aurora has a vast knowledge related to the ancient scriptures of the world, which allows her to create and formulate powerful spells that can help her in many ways. It is speculated that this was compulsorily learned while she was the victim of the Cult's experiments, researching her into magic. While Aurora and Cid Kagenō were looking for a way to get out of the Sanctuary, as they reached its core, Aurora was able to easily read the ancient rune writings that were written on the Hero's sword, which she supposed, that Cid had also read them. , in just an instant, (without knowing that he only guessed it).

Magic
While her full power remains unknown, Aurora is one of the strongest magic users in the series. Her fighting style appears to revolve around summoning and telepathically manipulating several different weapons. Whilst possessing Claire, she was also capable of taking control of Elisabeth's blood manipulation, redirecting her attacks and causing her body to explode.

Despite having been imprisoned for so long, her projection was capable of manifesting a magical door to summon the Shadow to her side. Aside from this, she can read magic runes.


 * Spell Caster: Aurora being a master of witchcraft, has the ability to cast strong spells of any kind either to support, or curse in extreme cases, when she came face to face with Shadow's older sister in her mental space, In the Red Tower of the Lawless City, Claire Kagenō, placed a spell mark on her right hand, to help her control and manage Elizabeth's cursed blood, allowing Claire, in certain circumstances, to use the blood spells she could use are presented to him and other things.


 * Witch Possession: Through the lineage of the Three Heroes, plus the compatibility of this, and the magic spells, it is speculated that Aurora can possess them and use them as temporary or permanent vessels, in order to exercise her witch powers to some extent, Until now she has only been able to do so with Shadow's sister during her fight with Elizabeth, being able to slow her down enough before the body she possessed reached its limit, due to the magical pressure exerted, she now inhabits Claire, making her her Body-Soul host. (It is not yet known if this was only possible, due to her witch power, or just because Claire was the most compatible as a host, for Aurora).

Blood Magic
Aurora can project a blood-colored magic spear from any direction unpredictably at such a fast pace that no magic knight can evade or stop it, even for an elite magic knight. Its attack speed is 2 to 5 times faster than that of ordinary bullets, rivaling that of rifle weapons.

This ability gives her such a fierce and almost inescapable attack power, that it is as if one were trapped in a kind of net, from which it is very difficult to get out or even survive. Usually, Aurora begins to project these attacks from below the ground feet, either at her enemies or at herself. When she first appeared, Aurora in memory form, used this ability against Shadow during the Goddess's Trial.

Blood Magic is her specialty. Her blood also forms the catalyst for Monster Progenitor situations and believed to be an important component for humans to achieve immortality.

Shapeshifting Weapon
Using her magic, Aurora is able to to summon wave after wave of weapons onto her target as she can project, change, control, and modify all kinds of weapons from spears to swords and scythes that she can use to launch them as projectiles or wield them with her hands through magic, even redirect them anywhere she wants (as a curious fact, all these tend to turn red).

Blood Manipulation
Aurora can manipulate or control the blood of those who carry her genes (usually the female descendants of the 3 heroes), to the point that she can control the blood of others who come into direct contact with her and use it against themselves. When Cid sister, Claire began to suffer from a type of "Vampire Curse" cast by Vampire Queen, Elizabeth, Aurora helped her to controlling it's curse through a spell and after she possessed Claire's body to fight Elisabeth, Aurora was able to stop her blood attacks from it and redirect them to her.

Trackable Perception
Somehow, Aurora can identify people and be able to locate them through her magic, even if they are covering their identities. When Cid in his Shadow alias defeated Aurora in the Goddess Trials and he left quickly, Cid was found shortly after by a magical door that prompted him to enter and after entering, Cid saw Aurora chained and Aurora she quickly identified him as Shadow.
