The Case Study of Vanitas
ヴァニタスの手記
In 19th-century Paris, a young vampire's quest for the Book of Vanitas sparks a dark crusade to 'cure' the vampire race.
It’s 19th-century Paris, and young vampire Noé hunts for the Book of Vanitas. Attacked by a vampire driven insane, a human intercedes, rescues Noé, and heals the sick creature. Commanding the book and calling himself Vanitas, this doctor tempts Noé with a mad crusade to “cure” the entire vampire race. Allying with one who wields arcane power so easily may be dangerous, but does he have a choice? (Source: Funimation)
