You have been summoned from our modern-day world into a fantasy world, to become the bodyguard of a beautiful young succubus. With the two of you now living together, you must learn to survive in this foreign world.

Choose between a male or female protagonist. Sexually train and level up your succubus companion, and evolve from a humble office worker into a powerful spellsword.

- Rebel Duet allows for traditional romances, harems, and healthy polyamorous relationships. It is up to you to decide the rules.
- Choosing a Male Protagonist leads to straight content, whereas a Female Protagonist is primarily lesbian with occasional (and optional) bisexual scenes.
- There are three main heroines, along with various side heroines and flings.
- The protagonist starts off weak, becoming much stronger in Act 3. If you are looking to play as a gigachad right away, this game may not be for you, as it takes some time to reach that point.

You inherit your grandfather’s residence in a coastal town, but to save it from an unpayable debt you must manage your relationships with a group of female tenants willing to do anything to help you. As you explore the town, you’ll discover that the place hides a dark secret tied to girls only you can see. Your success will depend on your ability to seduce the women living in your house and unravel the desires of those who refuse to leave it—before the past comes to reclaim the property.​
