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.
