Aurora

A woman known by the alias "Witch of Calamity." She is said to have brought destruction and chaos to the world, but no specific actions are recorded, and her actions remain unknown.

In the goddess's trial in Lindblum, she was summoned as a being fitting for Shadow. At this time, Shadow did not know her name and temporarily called her "Miss Violet" based on the color of her eyes. She attacks with a spear-like object formed from a red liquid, but Shadow, observing her, realizes she is not fighting at full strength and defeats her with a counterattack.

Later, she meets Cid in the sanctuary, who releases the restraints on her, and they start acting together. After being released from the sanctuary, it also meant her death, but she thanked Cid for the freedom and set off on her journey.

Afterward, as a consciousness, she travels around the world and, during a battle with the Blood Queen Elizabeth where Claire is critically injured, she temporarily borrows a body to repay her debt to Cid, helping to buy time until Shadow arrives. She then unilaterally makes a contract with Claire, agreeing to lend her power in times of need.

In fact, she is the true form of Diabolos. About 1000 years ago, she was isolated by the Holy Church as a subject due to her unparalleled magical power, and it is unclear whether it was due to a magical outburst or some other cause, but she mutated into Diabolos.

In the web version, Cid discovers "Diabolos's Little Finger" in the ancient castle of Ragitta and heals it back to its original human size using a method similar to exorcism due to demon possession, making it easy to possess because it's his own flesh, and then he and Cid start searching for "Parts of Diabolos."

In the TV anime version, in Season 2, Episode 3, when making a contract with Claire, for some reason, she appears in a space with advanced technology like computers, recreating a real-world school's infirmary, dressed like a school nurse. Also, during the battle with Elizabeth, she tries to mimic Shadow's "I Am The All-Range Atomic" that she witnessed in the sanctuary, but Claire's body cannot withstand the immense magical power and self-destructs, resulting in a failure.

One of the few who can fight on par with Cid. She is one of the few people outside of Shadow Garden who knows that Cid is Shadow, and she is able to interact with Cid, even though communication seems to be one-way even among the Seven Shadows.
