Undertaker is an eccentric, enigmatic individual who giggles frequently, appreciates laughter, enjoys frightening others and provoking reactions with his strange mannerisms, and spends a considerable amount of time in coffins. He works as a funeral director for normal society. Because corpses, are ordinarily delivered to his place of business, Undertaker is able to inspect them, whom he refers to as his "guests," he expects those seeking information on the corpses to amuse him in some way.
