The Case Book of Arne

Shido Tatsuhiko is not only a private eye... he is also a vampire with no real memory of his past. Joined by Yayoi Matsunaga, a female government agent, Riho Yamazaki, an orphaned teenage girl working as his girl Friday and Guni, a little green imp, Shido must face demonic creatures known as Nightbreed. Meanwhile, Cain, the vampire who made him what he is now, is seeking him...

It’s 19th-century Paris, and young vampire Noé hunts for the Book of Vanitas. Attacked by a vampire driven insane, a human intercedes, rescues Noé, and heals the sick creature. Commanding the book and calling himself Vanitas, this doctor tempts Noé with a mad crusade to “cure” the entire vampire race. Allying with one who wields arcane power so easily may be dangerous, but does he have a choice?

The 19th century — a world inhabited by vampires, golems, werewolves and other paranormal creatures. Immortal beauty and disembodied head Aya Rindo, along with half-human-half-demon "Demon Killer" Tsugaru Shunichi and her loyal maid Shizuku Hasei, travels through Europe as supernatural detective "The Cage User," solving supernatural mysteries while she searches for her lost body.

Kindaichi and the gang are on their way to a hot spring, but get lost and end up at a run down and sinister hotel. They are told that a vampire used to live in the hotel way back. Someone even died (was found with bite marks on the neck). Six years ago a girl was found in the cellar with bite marks on her neck, and the villagers killed her. When one of the guests is killed and Miyuki is attacked by a creature with fangs, it would seem like the vampire is still there...
