Set in 19th century France in a world where humans and vampires exist, a young vampire named Noé is on his way to Paris in search of a grimoire called the Book of Vanitas, which is said to be able to curse vampires. However, on the way there an incident leads to him meeting a self-proclaimed doctor specializing in vampires named Vanitas, and it seems he is in possession of the book. Soon, Noé finds himself thrust into a conflict that threatens the peace between humans and vampires!
