A nurse with unorthodox methods. Once served as the grand empress' royal servant alongside his sister before the prince went mad and stole her powers. Now waking up with a splitting headache and a parasite attached to his head, he has to trudge forward to knock some sense back into the prince before things get even worse.
Ludwig is deadpan, and aloof. But not because he doesn't like socializing with others. It's just that he has never spoken to earthlings before. Thus, in reality he is very much awkward but tries his best to catch up with everyone. He has a hard time changing his facial expression.
That thing on the back of his head is named Mr Hyde.
