Plot
Rumors revolving around The Book of Vanitas, a clockwork grimoire of dubious reputation, draw Noé, a young vampire in search of a friend's salvation, to Paris. What awaits him in the City of Flowers, however, is not long hours treading the pavement or rifling through dusty bookshops in search of the tome. Instead, his quarry comes to him...in the arms of a man claiming to be a vampire doctor! Thrust into a conflict that threatens the peace between humans and vampires, will Noé cast in his lot with the curious and slightly unbalanced Vanitas and his quest to save vampirekind?
