The Dungeon Core's Butler

A haughty dungeon core, that either pretends, or believes, to be a young noblewoman. A beleaguered customer service employee, given a second chance in another world as a monster in service to said dungeon core. Both working together to fend off the forces of boredom in an abandoned manor that hasn't seen a guest in years. Will the Ojou-sama Dungeon Core manage to restore the wealth and prestige she never had? Will the Customer Service Worker be able to enjoy a life of servitude in a world that at least appeals to his love of isekai fantasy and RPG mechanics? Will they ever have a guest? Find out all of this and more in: The Dungeon Core's Butler!
