Born into an old aristocratic family, Rouchard enlisted in the Gendarmerie Nationale at her first opportunity as a way to avoid compulsory enrollment at a notorious Swiss finishing school for young women. As Aspirant in the Gendarmerie, Rouchard quickly impressed her senior ranks by excelling in offensive strategy and hostage negotiations, but most of all, blade-based combat. Several promotions later she is best known by her moniker 'Le Couteau' (The Knife), although some would say this is because she can be a bit blunt at times. Today, Rouchard gets called in when no one else knows what to do.
