Camille is Mosquiton's wife from three centuries before the main events, retaining profound romantic feelings for him. She actively seeks to reignite their relationship despite his current contract with Inaho. Her first appearance occurs on a cruise ship, where she immediately attempts physical intimacy upon reuniting with Mosquiton. This act provokes intense jealousy in Inaho, sparking confrontations between the two women. During these clashes, Camille openly declares her spousal history with Mosquiton, escalating tensions further.

Three hundred years prior, Camille actively desired to become a vampire through Mosquiton's bite, driven by her wish for eternal companionship with him. After Mosquiton aligns with Inaho, Camille pursues them to Shanghai. There, she negotiates with Inaho, pledging obedient service in exchange for proximity to Mosquiton. Camille assumes the domestic duties previously handled by Mosquiton, including household chores and cooking. Her culinary skills exceed Inaho's, intensifying their rivalry.

Camille professes a philosophy of eternal love, stating she accepts Mosquiton's other relationships as expressions of his vitality. She employs passive-aggressive tactics against Inaho, notably suggesting that Inaho's eventual aging and death will naturally resolve their conflict over Mosquiton. In one incident, triggered by Inaho's blood causing Mosquiton's violent transformation, Camille endures physical abuse from him. Her narrative presence concludes without resolution to her romantic pursuit.

In the television adaptation, Camille's role is significantly reduced. Her backstory as Mosquiton's wife is omitted entirely. She appears solely as a subordinate within Germaine's faction, lacking meaningful development or connection to Mosquiton's past.
