Due to being born a girl, you were denied your birthright of becoming the ruler of your kingdom. All is not lost, however, as you make your intention known to become the queen. It's not an easy path, and you will have to maneuver politically between the royalist Summer Party that support your cousin, the duke, and the Winter Party that seeks more power to the common noble. Not only this, you'll have to balance your influence among the general populace, the military, and even the church, if you are to win the coveted throne and become the heir.
"Mistress vs Slave" is a mix of political sim with visual novel elements, coupled with role-playing, and sexual content. The game contains graphic sexual content and multiple endings, where choices matter.
