Anne Shelley has served as personal maid to Catarina Claes since Catarina's childhood. As the illegitimate daughter of a nobleman, she occupies a distinct social position within the household. She possesses dark brown hair cut to neck length, brown eyes, and maintains an adult demeanor fitting her role. Anne lacks magical abilities and ranks as the physically weakest character, possessing the lowest combat capability. Despite this, she exhibits practical competence in managing daily affairs and a consistently calm, supportive personality. Her most notable skill is adeptly handling Catarina Claes's unpredictable behavior, making her one of the few individuals capable of exerting any control over her; this ability stems from her deep, long-term familiarity with Catarina's habits and temperament. Throughout the series, Anne demonstrates unwavering loyalty and protectiveness towards Catarina. She provides discreet assistance in personal matters, such as helping Catarina navigate social challenges like bullying incidents, while typically avoiding direct confrontation. Her background as an illegitimate child occasionally influences her reserved demeanor, though this aspect remains unchanged. Anne's character does not undergo significant evolution or expanded backstory in later seasons, films, OVAs, or spin-offs. Her role remains focused on her duties as a maid and her steadfast support of Catarina, without exploration of personal ambitions or external relationships beyond this dynamic.
