He is an Ehrenfest Archduke Candidate. Former commander of the Knight's Order of Ehrenfest. Karstedt and Elvira told him to stay away from Rozemyne so as not to accidentally endanger her life. He relies too much on his strength to solve all his problems. According to Karstedt, Bonifatius had been denied the position of archduke because of that logic. According to Bonifatius, he had in fact intentionally avoided becoming archduke because he considered the whole thing annoying. He has blond close to maroon hair and blue close to light blue eyes.
