Under the chilly sky, black clouds rolled, overcast winds gusted, a lightning cut through the night sky, and deadly demons and ghosts attacked the ancient town. The game is set at the end of the 19th century. Vampires occupy the ancient town all year round, suck up countless human blood, and have been trying to give their offspring and three vampire brides life. Under the evil cover of the vampire family, God launched a series of plans to eliminate them and promised that their souls would not go to heaven.
