The moment Vanitas saves that vampire, you realize this isn't going to be about hunting monsters. It's about whether you'll follow someone beautiful and broken into a war against his own nature. Noé doesn't have a choice, and neither do you. The show knows exactly how to make damnation look like salvation, and by the time you understand what Vanitas actually is, you're already complicit in his logic.

In nineteenth-century Paris, a young vampire named Noé searches for the legendary Book of Vanitas, hoping it can help save a friend. While he is traveling aboard an airship, a vampire driven mad attacks him, and an eccentric doctor steps in, rescues him, and restores the afflicted creature to its senses. Calling himself Vanitas and carrying the very book Noé seeks, this self-styled vampire specialist turns out to be human, having inherited both his name and the grimoire from his master. He invites Noé to join his bold campaign to cure the whole vampire race. Joining someone who handles arcane power so easily may be risky, yet Noé is soon caught up in a conflict that endangers the fragile peace between humans and vampires. A supernatural mystery with action and drama, it pairs its period setting with an unlikely partnership.
