In Enid Blyton's original St. Clare's book series, Miss Roberts serves as the twins' form mistress—a strict yet fair educator who identifies prank instigators and enforces classroom discipline. The anime adaptation "Mischievous Twins: The Tales of St. Clare's" depicts the O'Sullivan twins, their family, classmates like Janet, Kathleen, and Hilary, and faculty such as Mam'zelle. Srta. Roberts does not appear in any iteration of the anime, including seasons, films, OVAs, or spin-offs.
