Description
Vanitas, a human wielder of the ancient grimoire tied to the Vampire of the Blue Moon, dedicates himself to curing vampires plagued by Malnomen—a corruption of their true names. Born to a physician father and a performer mother who died in childbirth, he grew up among traveling entertainers until a vampire attack orphaned him. The Catholic Church later inducted him as a Chasseur, honing his skills as a vampire hunter, before his abduction by the manipulative Doctor Moreau. Designated "No. 69," he endured brutal experiments, forming a protective bond with Mikhail ("No. 71"), another subject. Both received injections of the Blue Moon vampire’s blood, granting them rapid regeneration.

Rescued by the Vampire of the Blue Moon—later known as Luna—they learned the experiments would prove fatal. Luna offered to transform them into their Kin to survive. While Mikhail accepted, Vanitas rejected immortality, clinging to his humanity. When a violent clash forced Luna to mark him as Kin to save his life, Vanitas mistakenly believed he had slain both Luna and Mikhail, fueling his self-hatred and driving his vengeful mission to heal curse-bearers.

Androgynous in appearance, Vanitas possesses pale skin, unevenly cropped black hair, and piercing blue eyes. His attire—a dark blue vest, voluminous black coat, and Luna’s hourglass-shaped earring—complements his arsenal: the Book of Vanitas, concealed blades, and medical instruments. His combat style blends Chasseur-trained precision with deceptive tactics, exploiting vampires’ vulnerability by targeting their eyes to disrupt their manipulation of the World Formula. Enhanced healing from Moreau’s experiments grants him resilience beyond ordinary humans.

Charismatically reckless, Vanitas veils self-loathing and distrust beneath playful flirtation and sarcasm. He avoids sleeping near those he doubts, yet forges fraught alliances, such as with Noé Archiviste, a vampire ally, and Jeanne, a vampire he initially manipulates before genuine affection emerges. Reunions with Mikhail reignite guilt and rage, pushing Vanitas toward violence before tentative reconciliation.

Alternate media portrayals depict him as a cross-dressing student pursued by an oblivious Jeanne in an audio drama, while stage adaptations expand his dynamic with Noé and Jeanne—though these exist outside primary canon.

His journey grapples with trauma, hatred, and the paradox of saving those he resents. The Book of Vanitas symbolizes both his tether to Luna and his desperate redemption, propelling him to heal others even as it mirrors his own fractured soul.
