Risette is a young woman with light azure hair and yellow eyes. She dresses in a blue maid style outfit consisting of a headpiece, blue dress with white frills and puffed sleeves, dark tights held by suspenders and white and blue heeled shoes. She also wears long black gloves of a similar material to her tights and blue and white gloves above them. Risette uses both a pistol and blade in combat known as gun & blade gear.
Despite her appearance giving off a cold impression, she is actually very social and polite, and has a cute sense of humor.
Risette is an employee of M.T.S.C.
Unlike her graceful appearance, she has superhuman strength, speed, and combat capabilities that at times surpass even seasoned jaegers. Her relationship with Spriggan Van Arkride is "strictly business", giving him weapons and exclusive Xipha apps free of charge, and in turn collects data from his usage as an external tester.
During the course of the story, it is revealed that Risette is a cyborg.
- Her pre-order outfit is reminiscent of 2B, a character from NieR Automata. It's a nod to the fact that Risette is a cyborg.
- Risette being a cyborg references both the main character of the book series Heartless Edgar and Lapis Rosenberg, both of which were also mechanical humans.
