Vivian serves as captain of Saint Patrick Academy's equestrian club. Renowned for her exceptional horsemanship skills, she has earned the nickname "Queen of Horseback Riding." Her peers admire her talent and dedication to the sport. Despite being strict and demanding, Vivian is a gifted rider with aspirations to obtain the Lady Crest. She was previously Andrew's rider but now currently trains Elizabeth.
Vivian initially viewed Lynn as a threat when she successfully tamed Andrew, leading her to become harsher towards Lynn. Her dislike for Lynn intensified after noticing that Edward showed more interest in Lynn than herself. To further distance herself from Lynn, Vivian allied with Mary, who also harbored resentment against Lynn due to her role in ruining her mother's marriage arrangement.
Following an accident, Vivian's perspective on Lynn gradually shifted, and she began accepting her and even supporting her through her struggles. She is often accompanied by two assistants.
