The Case Study of Vanitas

Noé travels on an airship in 19th century Paris with the goal of finding the Book of Vanitas, a cursed grimoire said to have been created by the vampire Vanitas. His search is put on hold when a vampire attack brings him into contact with Vanitas, a doctor specializing in vampire-related cases who claims to be an ordinary human. However, this Vanitas has inherited the name and the book from his namesake, using it to heal patients while struggling with his own dark past.
