The kingdom in the Human Realm which Princess Prin Prin is the ruler has no known name, but as she has been referred to as the "Princess of Hus" in the English version of Ghouls 'n Ghosts, it is implied that Hus is the kingdom. The fact that all human characters have been associated with characters in Arthurian legend (Prin Prin has also been referred to as Guinevere, Lancelot and Perceval appear as playable characters in the Gold Knights series) has lead some to assume that they reside in the castle of Camelot in some capacity, though this has never been in canon material.
