After the day Malak left the Von Stein family castle, the security got higher, and it seemed the two rank-four vampires had something on their minds.
"Someone is trying to betray us. First is Malak's appearance, which should be locked away; now, my treasure box is missing. There is no way this is normal."
It was not the first time they suspected something was amiss inside the castle. Some time ago, they ordered some guards to keep a close watch on some people they were suspicious about and also to ask others if they saw something strange, yet it was not a success, and they found nothing.
But finding nothing did not mean there was nothing to see. They just had to look deeper. So, dark times arose in the castle, where everyone could be the culprit of something, even the weakest servant.
Yet, out of all the suspects, there was a group that was the primary one: the recruits! Not many vampires came to the family recently, those only being the recruits they chose for their army.
