Veronica de Sade holds a high rank within the aristocratic House de Sade and serves directly under the Vampire Queen as a member of the Bestia. She is the second child of the family, granddaughter of the enigmatic "The Shapeless One," younger sister to Antoine de Sade, and elder sister to twins Dominique and Louis de Sade. The family name draws inspiration from the historical Marquis de Sade, reflecting thematic connections to power and extremity. She presents as a pale young woman with silver hair styled in a hime cut featuring straight bangs and thigh-length strands. Her distinctive features include cross-shaped pupils and a mature, beautiful face with angular eyes and long lashes. Veronica often wears elaborate, culturally blended attire, such as a costume combining Japanese furisode kimono elements with fox mask motifs during the Bal Masqué, later appearing in loosely fastened robes exposing cleavage and thighs, incorporating Japanese aesthetic influences despite her European origins. Veronica displays pronounced misandry and human hatred, reacting with visceral disgust to human presence—particularly males—stating Vanitas's scent made her "nose may just drop off." Her personality is cold and malicious, demonstrating enjoyment of torture through ownership of devices like iron maidens and her use of a specialized collar on Dominique. She verbally abuses Dominique, labeling her the "family failure" and criticizing her lack of lineage knowledge and reluctance toward violence, though showing surprise at Dominique's drastic actions like cutting her hair. During the Bal Masqué arc, Veronica attempted to eliminate Vanitas for intruding into Altus, rallying other vampires for a human hunt. She later confronted Dominique for collaborating with Vanitas and Noé Archiviste, leading to a physical altercation where she incapacitated and bound Dominique before attacking Noé and Vanitas. Her cryokinetic abilities allow precise manipulation of the World Formula to conjure and control ice—forming spiked pillars, levitating blocks, and freezing targets—alongside exceptional visual perception enabling formula editing despite limited vision. Veronica shares a casual, physically intimate relationship involving blood-drinking with Marquis Machina, which she dismissed as a "fling." She harbors open disdain for August Ruthven, glaring at him when interrupted and calling him an "eyesore," though complies with his commands due to respect for his authority. Her interactions with brother Antoine appear cordial. Her name, meaning "she who brings victory" in Greek, aligns with her assertive role in vampire society. Her background reveals involvement in family dynamics; she disclosed to Dominique that their grandfather, the Teacher, intervened to take Louis as an experimental subject based on their father's arbitrary choice. This reflects the family's internal power structures, where Veronica holds authority as a Bestia member while Dominique occupies a lower status. Veronica's actions consistently reinforce her alignment with vampire aristocracy and its hierarchies.
