The Case Study of Vanitas (Season 1)

The Case Study of Vanitas (ヴァニタスの手記, 2021) is a Japanese anime series you can watch online on iFILM, animated by Brain's Base and adapted from Jun Mochizuki's manga. The story drops into a steampunk version of 19th-century Paris where vampires move quietly through human society — until a young vampire named Noé crosses paths with a human who shouldn't have what he's carrying.

The human calls himself Vanitas. He has the grimoire known as the Book of Vanitas, a legendary artifact — and he claims he can use it to cure vampires whose true names have been corrupted. Noé is sceptical, suspicious, and unable to walk away. Vanitas was born under a Blue Moon and cast out by his own kind; the resentment sits close to the surface, but so does something else the show takes its time revealing.

The series earns its attention with unusually sharp visual design — the airships, the gothic architecture, the detailed period detail — and a central duo whose dynamic runs on genuine wit rather than just bickering. Stream all episodes of The Case Study of Vanitas online on iFILM.
