Georgie Saikawa, born Nae Saikawa, is Riko Saikawa's elder sister who adopts the alias "Georgie" while acting as a self-proclaimed family maid. She consistently wears an orange polka-dot maid dress with a white apron and cap, black striped stockings, and sports red twin pigtails, maintaining this attire for daily activities, family gatherings, and public outings.

Calm and supportive, especially toward her sister, Georgie developed an intense childhood passion for maid culture after reading a book on the subject. This led her to deeply study maid etiquette, tea service, and related knowledge, often causing her to forget her birth name "Nae" in her maid persona. To fund her handmade maid outfits—showcasing her sewing precision—she works part-time in an amusement park mascot costume.

She first appears in Episode 6 of the first season, inviting Tohru and Kobayashi to her home and bonding strongly with Kobayashi over shared maid enthusiasm, inadvertently excluding Tohru. Later appearances include attending Riko’s school Sports Festival, participating in New Year shrine visits where she draws a fortunate omikuji, arranging hinamatsuri dolls, advising Tohru on maid outfit design, and cosplaying as an amusement park mascot.

In the spin-off "Kanna's Daily Life," Georgie hosts Kanna for sleepovers, teaching her about dedication and service in maid culture. A notable moment occurs when Kanna fails to recognize Georgie in school uniform due to her habitual maid attire. The spin-off also shows Georgie studying for exams, experimenting with makeup, preparing chocolates for Kanna, and warmly engaging younger children.

Georgie addresses Riko as "milady" publicly and privately, occasionally slipping to use her first name. Her connection with Kobayashi centers on mutual interest, with both calling each other "comrades." Tohru initially sees Georgie as a rival but grows to respect her commitment. Across media, Georgie balances her maid identity with typical teenage experiences.
