Faury Carat heads the Carat Firm at fifteen years old, known for her unyielding and carefree personality. She actively competes with fellow Tristia inventor Nanoca Flanka for acclaim and rewards tied to their inventions. This rivalry fuels frequent disputes, even during lunch breaks while feeding Nanoca, and moments where Faury becomes shy if subjected to physical contact like breast fondling. Her inventive activities, alongside others, drive the economic revitalization of Tristia, where creating and selling items directly fuels the city's development and commercial growth. Nanoca's arrival in Tristia significantly intensified their competition, leading to numerous troublesome incidents.

Physically, Faury is a teenage girl with long purple hair extending past her hips and blue or green eyes. She typically wears a dress and a hair ribbon.
