Chevreuse grew up in Fleuve Cendre. She is the present Captain of the Special Security and Surveillance Patrol and a frequent customer at Beaumont Workshop, often purchasing expensive materials to maintain her musket. According to Riqueti, Chevreuse has commented about the Patrol's scarce usage of Gardemeks while under her command, claiming that "Gardemeks will only block our bullets!" In her spare time, Chevreuse enjoys reading, particularly books in which justice prevails over evil.
