the prince of the black sun and his pet

A prince cladded in deepest darkest in a kingdom of the demons of the darkness of the black sun, the prince bored of his throne goes into the forest of light where he finds a demi human of platnum white hair with skin as white as snow and with eyes of a deep blue and emerald green. The prince charmed by the demi human's beauty offers him a place in his palace as his personal pet.
