Viscount Druitt is a Noble that was one of the main suspects for the Jack the Ripper murders. He graduated from Medical School but does not practice medicine. He is later revealed to be kidnapping women and using their body parts for the Black Market and was arrested by Scotland Yard. He returns as a curry judge and a ice sculpture judge, with Ciel believing that he must have bribed his way out of jail. He has a habit of relating anything he sees as beautiful to that of women. Comically Ciel keeps getting creeped out when he refers to when he had to dress up as a girl for a disguise.
