Demius is a fat, jolly man with an ever-present twinkle in his eye. It is almost impossible to maintain a serious demeanour in his presence as he is an incorrigible flirt, often complimenting females or smacking the ample bottom of his wife in public.
With his wife, Maryll, Demius operates a quaint shop called Demi and Maryll's Baked Goods in Hashan which sells an assortment of delicious pastries.
