[Machine Translation] Once every ten years, you are chosen as the "bride" to marry the King of Eberwein. However, having been born and raised in the castle town of Eberwein, you knew very well that the true role of the "Bride" was only a sacrifice to the vampire king. On the night of your dedication, Dietrich, the king of the vampires, and his brother Viktor appeared before you at Eberwein Castle. You were frightened, but Dietrich told you that he would make you his "bride to share" with him.
