Viscount Gerhardt von Waldstein, a vampire who rules the island of Growerth in northern Germany as the Master of the Night, resides there. His accepting and merciful nature has naturally drawn many nonhumans to the island seeking a home. Waldstein Castle is inhabited by a variety of colorful characters, including fellow vampires, witches, and werewolves. However, the chief residents are the viscount's family—his twin children, Relic and Ferret. Not far from the castle lies the city of Rukram, whose mayor is a trash-talking Dhampyr with a grudge against the viscount. There also appears to be a young woman with a taste for vampire flesh, as well as a shapeshifter who has a complex regarding his true form. Then there is the mysterious Organization—a group of vampires plotting... something. No one knows exactly what they are up to, not even the members themselves. Vamp is a vampire series by Ryohgo Narita and an early installment in the Naritaverse, alongside Baccano! and Durarara!!.
