Anne is a first-class bookman for the World Gourmet Organization (WGO), selected as an impartial judge during the Régiment de Cuisine competition between Central and the rebel forces. She insists on tasting dishes before decisions and halts premature ridicule from others, upholding fair judgment. She possesses long, dark hair reaching her knees and wears a white frilly long-sleeved top, a dark layered skirt with white frill accents, and black slippers. Her personality blends mischievousness and condescension, evident when teasing Sōma Yukihira about his family restaurant's absence from WGO records. Anne exhibits near-eidetic memory, recalling WGO archive information precisely, though she struggles with idioms like "the proof is in the pudding" without consulting her books. Notably, Anne has an extremely low alcohol tolerance, becoming intoxicated after a small cup of undiluted sake. Paradoxically, her tasting abilities reportedly enhance in this state. Her background includes training under fellow WGO members Decora and Courage. During the BLUE tournament arc, Anne represents the WGO, overseeing preliminary challenges where contestants must pass three culinary trial gates to reach the final competition before the Bookmaster. These challenges involve creating a "worthy last supper" for an elderly former Noir chef, crafting high-value dishes using only convenience store ingredients, and impressing top WGO judges. Her involvement continues as the Bookmaster—revealed as Erina Nakiri's mother, Mana Nakiri—declares the winner will become her personal chef. Anne's role remains primarily observational and evaluative, facilitating the competition's structure and upholding WGO standards during high-stakes culinary battles.
