The creator of alchemy in the skydoms, Cagliostro sought to achieve immortality, and in turn, discovered a way to swap out her body at regular intervals. An extreme narcissist capable of creating her ideal body at will, she created her current self in the pursuit of idealized cuteness. However, her attempts at matching it with an equally cute voice often leave something to be desired. Cagliostro is supremely confident, which causes her to view others as incompetent buffoons. Forever greedy in the ever-changing world around her, Cagliostro pursues alchemic research with single-minded stoicism.

Some time prior to the war between the Sky Dwellers and the Astrals, Cagliostro lived as a sickly boy close to death. With the aid of his younger sister, he pursued methods to avoid his early demise regardless of how the people in village thought. After many failures, Cagliostro was able to create a new female body and transferred his soul into it. That wasn't the end. She refined the technique and kept at her research, coining the term "Alchemy," thus becoming the founder of the practice. Word spread as Cagliostro made her art grow, garnering awe and even disciples wishing to learn from her.

Cagliostro taught her younger sister alchemy and she continued to research with her aid. The younger sister, as talented as she was with destruction alchemy, had no interest in the immortality Cagliostro had created for herself. Once she settled down with a husband and children, Cagliostro's sister retired from alchemy. In return for her help and out of affection for her little sister, Cagliostro bought a secluded island for her to live out the rest of her days in peace. Eventually, she was put to rest there.

One day, Cagliostro was approached by the Astrals and was promised great power in exchange for following their commands. It is unclear whether this happened before her sister's death but Cagliostro declined and soundly trounced the Astrals when they tried to force the matter. That was not the last time Cagliostro had come to odds with others due to her infamy.

The Alchemists of Helmuth, using the image of Cagliostro's sister as their symbol, would corner Cagliostro. They found that Cagliostro had become too wild in her actions, sullying the name of her own practice. This guild utilized their founder's main weakness, destruction alchemy. Before she was sealed away for countless years, Cagliostro vowed to return and make heads roll.
