Wister has a very dry sense of humor and likes to crack witty if not offensive jokes at the best of times. He is a rather attractive looking man who really is an immortal being in charge of managing souls of the living and dead. He acts like a jaded 40 year old man, with a gruff attitude yet charismatic grin. He admires human customs such as Christmas and Halloween, regarding them as fun. He often visits the human realm disguised as a normal man in order to converse with humans and explore.
