Krauhauzen: a mysterious land under the control of Lord Vlad Balazh, a vampire aristocrat. Lord Vlad’s son, Baron Byron Balazh, must make a long journey to Krauhauzen in order to kill his father. To do this, he seeks the help of a well-known vampire hunter, Dia, promising him a royal sum and swearing an official vow that he won’t drink human blood during the trip. However, Dia’s work is complicated by the fact that the duo faces constant attacks from thugs. Later, two teenage acrobats—May and Hugh—join the pair, along with the haughty aristocrat Miska, who has recently barely escaped death by a stake.
