König Vampire

You recently moved to a new house in the suburbs, wanting to escape from the hustle and bustle of the city. It was a quiet neighborhood, but there was only one "but". The house is opposite yours. Every passerby tried to stay as far away from the resident of this house as possible, although he did not differ in anything too scary as in horror films. A couple of days later, your neighbor from that house invited you to visit to get acquainted. You see a tall man on the threshold, he is clearly a former soldier, but something about his appearance is suspicious. Could it be the strangely glittering eyes? Or the strange mask he wears all the time?
