Veronica de Sade is a high-ranking vampire aristocrat from the de Sade family, serving directly under the Vampire Queen as a Beastia. She is the second child of Count de Sade and granddaughter of the enigmatic figure known as "The Shapeless One" or "Teacher." Her siblings are Antoine (eldest brother), Dominique (younger sister), and Louis (deceased twin brother of Dominique). Born into a family notorious for hedonism and sadism—inspired by the historical Marquis de Sade—Veronica embodies capricious behavior, casual sexual relationships, and an interest in torture devices, personally owning implements like an iron maiden. Her name, derived from Greek, means "she who brings victory" and "true image," reflecting her assertive nature. Veronica possesses silver hair styled in a hime cut reaching her thighs and distinctive cross-shaped pupils. She has a mature, feminine figure and favors elaborate clothing, such as a Bal Masqué costume blending Japanese-inspired elements (a furisode and fox mask) with European aesthetics. Later scenes show her in a revealing bathrobe, smoking a kiseru pipe, emphasizing her casual disregard for modesty. She exhibits extreme misandry and contempt for humans, reacting violently to their presence—declaring a "human hunt" upon encountering Vanitas due to his dual status as human and male. Veronica displays sadistic tendencies, taking pleasure in others' suffering, particularly psychological torment. Her cruelty focuses intensely on her younger sister Dominique, whom she verbally abuses as the "family failure" and physically restrains during confrontations. Despite sporadic moments of shock at Dominique's distress (like her haircut breakdown), Veronica shows no consistent protective instinct, instead reinforcing Dominique's insecurities about her role in Louis' death and the family's rejection of twins as "bad luck." Her actions drive key plot points: at the Bal Masqué, she incites vampires against Vanitas before shifting focus to curse-bearers during a mysterious illness outbreak. She later ambushes Dominique, Noé, and Vanitas, using her powers to subdue them. In flashbacks, she reveals to Dominique that their father spared her over Louis on a whim, deepening Dominique's guilt and self-loathing. Veronica wields cryokinesis, manipulating ice to create weapons or immobilize foes. Her "exceptional eyes" grant advanced perception even with limited vision, allowing precise alteration of the World Formula. Relationships define her motivations: - She shares a casual, sexual relationship with Marquis Machina, exchanging political information during encounters. - She despises August Ruthven, calling him an "eyesore," but halts attacks when he intervenes, acknowledging his power. - She antagonizes Vanitas for his humanity and gender. - Dominique endures her scorn for perceived weakness and association with Louis' fate.
