A homunculus whose body Mireille made that, by coincidence, possessed a will of its own at birth. Due to her creator's insufficient knowledge, Risette once suffered a state of hunger resulting from genetic factor deficiency that led to her consumption of the people in town as a means of survival. Afterward, she was reborn into a mortal person with the power of Cagliostro and a complete philosopher's stone. Upon becoming mortal, although she lost the ability to use the existential dissolution she once acquired from Clarisse's genetic factors, Risette has since learned to practice the basics of alchemy from Mireille. She has also gained characteristics of her own separate from her creator, including a talent for reproduction—an ability that allows her to create copies of things she can observe.
