Vanitas

Vanitas (ヴァニタス, Vanitasu) is a protagonist and the titular character of Jun Mochizuki's The Case Study of Vanitas. Contrary to the legend of Vanitas of the Blue Moon, Vanitas claims to be "an average human being" who happened to inherit the Book of Vanitas. It is his stated intention to save the Vampire race by any means possible, using the Book of Vanitas not to spread Malnomen but to cure it. As such, he refers to himself as a doctor who specializes in Vampires. He commissions the help of Noé Archiviste, a Vampire sent by his teacher to research the Book of Vanitas and the series' narrator, in finding cases of Malnomen and curing them.
