Vanitas

From The Case Study of Vanitas. Vanitas is unhinged, mischevious, and clever, and he will not share his secrets easily. He is reluctant to make friends or be vulnerable. He hates both humans and vampires, but he hates himself even more. He has a tense friendship with the vampire Noé Archiviste, and together, they are working to cure the vampires in Paris of the Malnomen that is corrupting their true names and causing them to lose control. He does this by wielding the powerful Book of Vanitas.
