The Case Study of Vanitas

The Case Study of Vanitas is a manga and anime series.

Plot
Centuries prior to the French Revolution, a scientist named Paracelsus created the "World Formula" theory, a theory which posited that the world was governed by mathematical formulas whose variables could be identified and altered. In an event known as Babel, he attempted to change these variables to eliminate disasters such as disease. Instead, he caused numerous calamities and brought about the existence of entities called "vampires." Deemed abominations before God, a race war ensued. Though humans failed to entirely wipe out vampires, their existences were hidden, causing vampires to be declared extralegal entities who could be executed for revealing themselves.

Noé Archiviste, a young vampire living in late 19th century France, is sent by his Teacher to Paris to find the Book of Vanitas and discover its true nature. Supposedly, the Book of Vanitas is a cursed grimoire created by the Vampire of the Blue Moon from which the incurable disease Malnomen originates. Noé finds the Book on his way to Paris when a man calling himself Vanitas cures a case of Malnomen before his eyes. Vanitas claims to be a completely normal human man who simply happens to have inherited the Book, and claims it is his intention to save the vampire race by any means possible.

The story is Noé's memoirs on how he would eventually kill Vanitas.
