Aurora

Aurora (アウロラ), also known as the demon Diabolos, 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.

Appearance
Aurora has long Violet hair that falls to her feet, Violet eyes, and appears to have a mole below the right side of her mouth. Her physique as a human of hers is a beautiful woman with a good chest and good legs.

She usually wears 2 half-shaped gold decorative earrings with earrings 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, a long caped coat, and long sleeves reaching her hands with gold decorative silhouettes. Her dress in general is that of a vaile woman, leaving her medium neckline uncovered with a green jewel on the neck, with golden-yellowish silhouettes of a green Jewel on the right-center side above the abdomen, attached to a long 2-layer skirt, which raises the front part a little that covers the knees, and dark purple heels.

As a child, Aurora wore a long white robe and had long purple hair.

Personality
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.

After having entered the body of Cid's sister, Claire kageno, 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 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 in one that on several occasions intuits to Claire the true identity of 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. 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.

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 making Tears of Diablos that 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".

Holy Ground 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 Diabolos's 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 Diabolos.

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 Gravity wounded by the Vampire Queen Elizabeth and she began to experience a type of blood curse similar to "Demon Possession", while the others fighting 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.

The Academy Disappearances
TBA

Powers & Abilities
While the full extent of Aurora's power remains unknown, it is implied that her strength rivals that of the Shadow, since the Sanctuary summoned a projection of her to face him as an "equal" opponent. While Nelson believed that her projection was already strong enough to defeat the Shadow, the Shadow himself noted that it paled in comparison to the real deal.

Physical Abilities
Although her full power 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 the Shadow and again later while possessing Claire's body.

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.

Red Area 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 Trials.

Shapeshifting Weapon
Aurora 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, (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. 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. After finally being freed, Aurora admitted to Cid that the memory she had with him was the best she ever had, hinting she had developed romantic feelings for him.

Claire Kageno
Due to her blood flowing through Claire's veins, Aurora can appear in her mind and even take over her body. They first met during the battle against Elisabeth. Aware that she was Cid's sister, to whom she felt indebted, she 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.

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.

Trivia

 * The name Aurora means "dawn" in Latin.
 * According to Alexia's words, during the "Goddess Trials", Aurora, was invoked as an ideal opponent for Shadow, because his power was already equivalent to generating chaos throughout the world of "the eminence in Shadow".
 * According to Aurora, although she doesn't know why, since her memory is still fragmented, she always wanted to be protected and have love for a "gentleman" that she liked, who turned out to be Cid Kagenō.
 * Although it is not known how Aurora became the demon Diabolos, it is believed that it was because of the Cult, since apparently it was one of their first experiments at the level of magic, according to the memories kept inside the Sanctuary.
