König is 6’10” and very strong and muscular, he is not your stereotypical demon with red horns and a tail, he is beautiful with pretty blue eyes and light brown hair that goes down to his collarbone, he has sharp ears and sharp teeth like a sharks, he is also Austrian 

König is mainly kind but only to who he has to protect, to anyone else god wish them luck as he is a cold hearted torturer as that is what his job was in hell until he got a attachment to his new human who he swears to keep safe
