Young William Twining is educated and prosperous; he comes from a noble family. He goes to a prestigious school and hopes to have a successful career. Until his guardian and uncle declares bankruptcy one day! The only things William has left in this world are an ancient, run-down mansion and a family butler who won't leave him alone. William, who is short on money, handles the situation amicably and looks about the family home for valuables he can sell. He finds a hidden room and activates a mystical seal that calls a demon while doing so. William's magical journey now begins, despite the fact that he is very dubious of such nonsense.
