Vanitas no Carte Episode 2

Afraid and alone, he created the "Book of Vanitas," a cursed grimoire that would one day take his vengeance on all vampires; this is how the story goes at least. Vanitas no Carte follows Noé, a young man travelling aboard an airship in 19th century Paris with one goal in mind: to find the Book of Vanitas.

The mysterious doctor has inherited both the name and the infamous text from the Vanitas of legend, using the grimoire to heal his patients. But behind his kind demeanor lies something a bit more sinister...
