So what is the Barons secret is he a vampire ? Sorry for being so clueledd (=・ω・=)

Sorry *clueless*

nah, the two punctures that made it look like the maid was sucked by vampires was explained in the first chapter, she was trying to escape so the baron had godo kill her. his secret is that he's albino, you can tell since he always wears those glasses and covers up and sign of his hair or his skin with his clothing - plus he's asked a few times if he looks like a freak compared to "normal" humans with black hair and dark eyes.
