The Case Study of Vanitas (2021)

Once upon a time, a pariah vampire named Vanitas was born under a blue full moon, a stark contrast to the crimson moon marking the birth of his kindred. Shunned and isolated, Vanitas crafted the "Book of Vanitas," a bewitched tome destined to enact his retribution on the vampire race—or so the legend narrates. The tale unfurls around Noé, a young voyager soaring through the skies of 19th-century Paris in a grand airship, his sole quest: to discover the elusive Book of Vanitas. His journey takes an unexpected detour when a sudden vampire assault brings him face-to-face with the enigmatic Vanitas—a physician whose specialty lies in vampire maladies and, to Noé's astonishment, a perfectly normal human. This peculiar doctor, who not only shares the name but also bears the notorious book of the legendary Vanitas, employs the grimoire's power to remedy his afflicted patients. Yet, beneath his benevolent facade, something far more ominous lurks, hinting at secrets yet to be unraveled.
