In the Succubus Kingdom game, you play as a man who has lost everything, but in your moment of despair, a pink-haired woman offers you a new life. However, nothing is that simple. This woman is a cunning succubus with the power of a goddess. Tricked and indebted, you become a Slave Knight, compelled to obey her every command. Surprisingly, she grants you fragments of her power and sends you to another planet.
It’s a magical and mystical planet where you’ll encounter elves, demi-humans, and many other races. What fantastical adventures await you in this new world? And, more importantly, what exotic women will you meet? Will you be able to free yourself from the succubus’s grasp and live your new life to the fullest, or will you remain her obedient servant? That will be your battle to fight.
