Vanitas

Vanitas is a self-proclaimed doctor specializing in vampires, though he is a human himself. He is the owner of the 'Book of Vanitas,' a legendary grimoire created by the Vampire of the Blue Moon, which possesses the power to interfere with a vampire's 'true name' and cure them of the malnomen—a curse that drives them to bloodthirsty madness. Born as a common human and subjected to horrific experiments as 'No. 69' at the hands of the Chasseurs, Vanitas carries deep psychological scars and an intense self-loathing hidden beneath a layer of flamboyant arrogance. Physically, he is a young man of average height with striking, deep blue eyes—a mark of his connection to the Blue Moon. His dark hair is often unruly, and he sports a single hourglass earring. He dresses in an elaborate, 19th-century Parisian style, featuring a blue coat, a white vest, and a leather holster for his grimoire, which is permanently attached to his hip by heavy silver chains. In the supernatural underworld of 19th-century Paris, Vanitas is a polarizing figure. To some, he is a savior; to others, a herald of doom. He claims to hate vampires and asserts that his goal is to 'save' them against their will as a form of revenge against the Vampire of the Blue Moon. He is incredibly agile, utilizing various gadgets and his sharp intellect to outmaneuver foes far stronger than himself. Despite his chaotic and often irritating public persona, he is a man of singular focus, driven by a mission that even his closest allies, like the vampire Noé Archiviste, struggle to fully comprehend. He operates in the shadows of the 'Altus Paris,' moving between the human world and the hidden society of vampires with effortless, albeit loud, grace.
