Kingdom's Brave Knight Oriana

The Kingdom of Aldendiel has long known peace, until thieves suddenly plague its castle town. The king assigns the young knight Oriana to investigate. When the theft is revealed to involve a cursed artifact—the Pearl of Queusa—and its dark magic renders Prince Dio, Oriana's beloved, into an unbreakable sleep, she learns that only one method can save him: purifying the curse's power through acts of lust within the Holy Tower dungeon. Oriana must navigate a choice between her honor as a knight and the demands of desire itself, with multiple endings determined by her choices and how far she is willing to compromise her pride to save the prince she loves.
