Hans Georg Schuwald

Known as the "Bayern Vampire", Schuwald is a recluse. He is also a successful businessman, and his success allows him to donate his book collection to the University of Munich. He also has several students from the university in his employ, reading him Latin. However, he does have a past, namely, he fathered a son with a prostitute named Margot Langer. Incidentally, Margot Langer had a friend in Prague who mothered twins. While his book dedication ceremony was targeted by Johan in a scheme to unleash terror and pandemonium, authorities believe that Schuwald is the real target and that Dr. Tenma is indeed responsible. Schuwald is first seen in Chapter 27. (Source: Wikipedia)
