Camilla serves as a supporting character working alongside Yor Forger at Berlint City Hall, part of a female clerk group with Millie Myers and Sharon. She has blonde hair, amber eyes, and light skin, typically wearing the city hall uniform: a green vest over a white long-sleeved shirt, green skirt, and black heels. Outside work, she favors fashion, donning a purple sleeveless dress with a golden butterfly brooch and blue heels for parties, or a purple long-sleeved shirt with a white skirt during home cooking lessons. Her two-story residence, spacious enough for gatherings, implies personal wealth.
Initially snobbish and mean-spirited, Camilla gossips with Millie and Sharon, mocking Yor's social awkwardness and unmarried status. She invites Yor to a dinner party expecting her to arrive alone, then joins ridiculing Yor for lacking a partner, even suggesting Yor might be a spy undermining the birthrate. After Yor reveals her marriage to Loid Forger, jealousy drives Camilla to attempt spilling hot gratin on Yor and insinuating Yor’s past involved illicit work. She reluctantly agrees to teach Yor cooking at her boyfriend Dominic’s urging but grows frustrated by Yor’s culinary struggles.
Camilla’s relationship with Dominic, a fellow city hall employee, reveals vulnerability. She acts possessively, pulling him away when he speaks to Yor at the party, and blushes when he calls her cute for assisting Yor. During cooking lessons, her softer side emerges: despite exasperation, she perseveres after noting Yor’s dedication to improving for her family. She adapts a stew recipe for Yor’s Eastern Nielsberg background, adding sour cream to recreate a childhood dish for Yor and her brother Yuri. Camilla also observes Yor seems "more lively" post-marriage, hinting at grudging acknowledgment of Yor’s happiness.
Over time, Camilla’s hostility lessens. When overwhelmed with overtime work, she accepts Yor’s assistance and calls her an "angel" in sincere gratitude. At a group dinner, Camilla and others tease Yor about her marriage but ultimately accept her "lovey-dovey" dynamic with Loid, finding Yor’s reactions endearing. During a charity bazaar for disabled veterans, Camilla acts deferentially toward the Lady Patriots Society to avoid conflict. She appears stunned when Melinda Desmond acknowledges Yor, confirming Yor’s prior claim, and swiftly intervenes when Millie confronts Melinda, covering Millie’s mouth to prevent escalation.
Though Camilla continues backhanded remarks—like suggesting Yor divorce Loid during marital worries—she gradually integrates Yor into her social circle through shared dinners and work camaraderie. This marks a nuanced shift from hostility to reluctant acceptance, though her sharp-edged personality lingers in subtler forms.
