A member of the Imperial Capital's Flower Division and a potential heroine, she is the daughter of the wealthy French aristocrat Count Chateaubriand. Her family consists of her father, Robert, and her mother, Marguerite.

She is a veteran member, ranking just behind Maria and Kanna in seniority; having joined while still in the single digits of age, she is also the youngest member of the group.

She goes by the name "Iris," which serves as both her nickname and the name she uses to refer to herself. She is rarely called by her real name by herself or others, and "Iris" is also the stage name she uses as an actress.

She possesses the greatest spiritual power in the Flower Division and is capable of using psychic abilities such as teleportation and telekinesis.
