Plot
Rügenberg is a city where supernatural beings and humans coexist. Arne Neuntöte, a young vampire with supernatural powers, runs a private investigation office specializing in occult cases. Despite his youthful appearance, Arne is an experienced detective who takes on requests involving curses, monsters, and unexplained phenomena that ordinary authorities cannot handle.
Arne works alongside Lynn Reinweiß, the daughter of a human nobleman with a strong interest in vampires, who becomes his assistant after a chance encounter. Together, they investigate a series of interconnected cases involving ghosts, werewolves, witches, and other supernatural entities, many of which are tied to the hidden history of the city.
