Aurora better known as the demon Diablos, was an enigmatic person from 1000 years ago, known as the Witch of Calamity who plunged the world into chaos, and is an exceptionally beautiful and exquisite woman of unparalleled elegance and radiates a class that distinguishes her. Her striking features epitomize her captivating charm. She boasts a stunning face framed by long, violet hair. Her eyes are a captivating shade of violet, and a beauty mark on the right side of her mouth. With a tall and slender figure, she embodies the quintessential image of a beautiful woman, complete with an ample chest, gracefully curved legs, and nearly translucent skin.

Aurora wears 2 half-shaped golden decorative earrings with an earring 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 green 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 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 dress-robe similar to a patient at a hospital.

Though long dead, the eponymous Cult of Diablos exploited her corpse for their own ends. Due to Aurora's amnesia, little is known about her past or motives. She had lost most of her memories from centuries of isolation in the white void memory prison by the time the current day of the "Goddess's Trial" happened 1000 years later. 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. Although the extent of Aurora's true power remains unknown, it is implied that her strength rivals Shadow, Aurora also 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.

Despite Aurora being of the most famous mages in history, she is still physically weak.

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. 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 Calamity", the woman who caused chaos in the world.

After becoming the Demon Diablos, her biology became demonic with great magical vitality, that even if her 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. 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. Aurora being a master of witchcraft, has the ability to cast strong spells of any kind either to support, or curse in extreme cases and 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,Aurora can identify and locate people through her magic, even if they hide their identities. Blood Magic is her specialty. Her blood also forms the catalyst for Monster Progenitor situations and is believed to be an important component for humans to achieve immortality.

Shapeshifting Weapon: Using her magic, Aurora is able 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: her own blood, those who can trace their lineage to the Three Heroes, and even Vampires, whose blood are a result of divergent adaptation of the blood of Diabolos.

Similar to Shadow, Aurora possesses the ability to copy and execute the powerful magical techniques of other users she knows just by seeing their techniques once. Aurora is able to reproduce or reinvent their techniques with just her body and magical power without depending on an artifact or a magical catalyst in it.
