Rix Vanus

The handsome and strapping Prince Rix Vanus has returned to his homeland after winning a brutal war against demons! And yet... Cursed by a vicious demon, the warrior prince is tormented nightly with shameful, lust-filled hallucinations as the demon takes the lascivious form of all his associates.

Escaping to the wild, miraculously, a benevolent divine spirit named Nuah joins the prince, seeking to break the curse and ease his suffering. And now, his nights —and more— are filled with Nuah.
