Aurora

Aurora (アウロラ), 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.

Appearance
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.

Personality
"There’s a beautiful woman bound before your very eyes."

- 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 Kagenou. 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.

Background
Not much is known about Aurora's past since her memory was fragmented. According to herself, she was a tearful girl isolated from everyone alone in a research area, unknown to her, at the mercy of some experiments by some bad scientists (presumably, the original members of the Cult of Diablos). According to Beta, several natural disasters that struck the world in the distant past were, in fact, caused by Aurora.

At some point in her life, as Alpha speculated, believing that her Master Cid knew, Aurora transformed into the Demon King Diabolos (although it is not known how or why), and began to cause destruction in the world until that was defeated by the Three Heroes of the world sent by the Cult, where it turned out that the Hero Olivier cut him her demonic left arm. But before dying, she unleashed a powerful curse on the them and their descendants, which provoked that the magical power of their bodies went come out control, causing them to begin to mutate horribly and in the end they became rotten monstrosities and then died, (it is not known if he did it intentionally or not). His amputated arm was still alive and the cult sealing the arm used powerful artifacts to immobilize it inside the Sanctuary, to carry out their experiment by extracting Diablos Cells in order to make Tears of Diablos, which will grant tremendous power and immortality.

A short time later without knowing it, a fragment of her being was trapped inside the sacred Sanctuary of the cult, becoming a prison and storage of past memories of Aurora, the Three Heroes and of the Cult of Diablos's member. She was locked up there for centuries (according to her, since she does not remember it but she supposes it), until that he will find someone with enough power to free her, in which the cult used her and the Sanctuary, to perform what would become known as the "Goddess Trials".

Sanctuary Infiltration
Nothing is known about Aurora's past except that she was a war orphan. Very few members among the church know of her story. She first appears as a memory when Shadow is forced to participate in the goddess trial at Lindwurm. Shadow defeats Aurora and uses the ensuing chaos to flee the premises.

Later, Cid Kagenou is surprised when a magical door crosses his path and stops him from going further. Cid opens the door and finds Aurora chained. He reluctantly saves Aurora who admits that she has been imprisoned for over a millennia. The two work together to escape the prison, which is actually a labyrinth of memories. They are arrived at the chained door with the Holy Sword. But, they were assailed by Acting Archbishop Jack Nelson and the memory of Olivier, but Cid defeats them and destroys the core of the prison, which is actually Diablos's left hand.

The prison is destroyed and Cid has a conversation with Aurora. Aurora tells him that she will cease to exist, but doesn't regret it at all. She also reveals that she was the one who summoned Cid and is glad to have met him. Before disappearing, Aurora tells Cid that if he ever finds the real her, he should kill her. Unknown to Cid, Aurora is the true identity of the great demon Diablos.

Red Moon Incident
When Claire went to the top of the red tower of the Lawless City, to rescue her brother Cid, (unaware that he was not in danger), Claire was gravely wounded by the Vampire Queen Elizabeth and she began to experience a type of blood curse similar to "Demon Possession", while the others fighting while she was unconscious. Aurora appeared to her in a sub-space inside Claire, starting to talk to Claire and helping her with her current state, giving her a spell that will allow her to control the 2 types of blood that flow and now inhabit her body, to later provide her support in combat.

By borrowing Claire's body, Aurora joins the battle manifesting a slight change of character Claire's eyes color from red to violet, with a portion of her power, enough to slow down, damage, and push back the vampire queen Elizabeth, until Claire's body she has possessed reaches its limit due to the magical pressure exerted on it. But luck of all and as Aurora expected, Shadow appears to face and defeat Elizabeth once and for all.

But then at the end the battle the next day, Aurora disappears again, leaving the mark of the Spell on Claire, so that she can help her in the near future.

Oriana's "Black Rose" Civil War Wedding Incident
Later, after learning of the existence of parallel universes from Mordred the 9th Seat Knight of Rounds, Beta questions him whether Aurora also came from one of these other worlds. However, he claimed that her assumption was false and that Aurora was a genuine inhabitant of their world, and telling her that the demon isn’t true form of the original Diablos. Mordred elaborated that they were the organism that became the basis for Diablos and theorized that Diablos called the original in from the First Realm.

The Academy Disappearances

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.

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 Kagenou 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 Kagenou, 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 identity. 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.

Cid Kagenō / Shadow
Having noticed his incredible power, Aurora summoned Cid to her in hopes that he could free her from the Sanctuary, even she acknowledged that Cid is the most powerful person she's ever encountered and would have been the one who could defeat her if he was born during Aurora's time.

The two immediately developed an amicable relationship with each other with Aurora affectionally calling Cid her gallant knight. Aurora became worried for Cid when he was seemingly overwhelmed by the Sanctuary and impaled through the heart by a clone of Olivier. When she thinks Cid is about to be killed, she offers herself to the Cult of Diablos to save him. Cid however shows Aurora why she doesn't have to worry.

After finally being freed, Aurora reveals that she's the one who summoned Cid in the Sanctuary and admitted to Cid that the memory she had with him was the best she ever had, hinting she had developed romantic feelings for him. Aurora request him to kill her if he find the "real" her.

Claire Kagenō
They first met during the battle against Elisabeth, due to her blood flowing through Claire's veins, which Aurora can appear in her mind and even temporarily borrowed her body. Aware that she was Cid's sister, to whom she felt indebted, she then unilaterally signs a contract with Claire and lends her strength in times of emergency, even aided her by taking over her body and fighting on her behalf. She also gave her a hint regarding her brother's true identity, though she did not pick up on it.

Since then, Aurora protects Cid's sister Claire from harm as thanks for him. She even admits to Claire about being a little envious on her for being always protected by a very powerful warrior like Cid. Aurora continued appearing in Claire's mind following their first meeting, regularly disrupting the latter's daily life. However, she refuses to elaborate to Claire what is happening to her, believing that Cid is trying to protect her. When Claire declares that she'll protect Cid with her newfound power only for Aurora trying to stop her because it's embarrassing since Aurora knew how powerful Cid is and not because it's an awkward moment for Claire.

Alexia Midgar
When Aurora saw Alexia, she thought to herself as she and Claire had shown how similar the two of them were.

Zeta
Aurora is very nervous when she saw Zeta as she warned Claire to stay away from her, when she didn’t know that if she is friend or enemy.

Fenrir
Long ago, Aurora had met Fenrir when he was a greedy assassin who only wanted to increase his own power to the point of being feared as the "Midgar Devil".

When Aurora saw Fenrir's true appearance, she was surprised because in her memory he should have been very old, even Aurora herself warned Claire about this while protecting her from Fenrir's attack.

Olivier
Despite having no proper recollection of Olivier in her memories, Aurora has an unexplained fear for Olivier. Aurora is aware that Olivier is extremely dangerous to the point that she rules out any possibility of a human being able to best her in combat.

Due to this, Aurora warns Cid not to engage in combat with Oliver, and even momentarily agrees to work with Nelson to save Cid.

Trivia

 * Aurora's mana color is "Blood Red".
 * According to Beta words, they suspect that the vampire curse of her blood has a certain similarity with the curse of Diabolos, but that is not yet known exactly, since according to Marie, this is blasphemy against her vampire queen, since she and yours are sure they have nothing to do with it.
 * According to Alexia during the "Goddess Trials", Aurora was invoked as an ideal opponent for Shadow, because his power was already equivalent to generating chaos throughout their world.
 * It is speculated that Aurora is the second most powerful being or creature in the world, before becoming the Demon Diabolos, only below Shadow, since according to Alexia, he had already reached a level of power that could only be rivaled with her, and then Shadow, managed to beat her in her "projected" state, during the "Test of the Goddess". and only above Elizabeth, being able to hold her back for as long as possible, implying here that if she were at her best, she would have been able to beat her without problem, in the red tower, of the Lawless City.
 * So far, it is speculated that Aurora may be the first witch in the world and also the most powerful of her class, having a vast knowledge of ancient runes and strong spells.

 * As Diablos, Aurora is indirectly responsible for causing the Cult of Diablos to be formed and placing the curse on the Three Heroes' descendants.
 * Aurora is considered to be the Cult's first success in creating a powerful superbeing with immense power, but this was accidental, as they were unable to control it.

 * Aurora's attire evokes a subtle resemblance to the Shadow Garden attire.
