Succubus Kingdom

You play as a man who has lost everything, but in your moment of need, a pink-haired woman offers you the gift of a new life.
But of course, nothing is that simple as this woman turns out to be a devious succubus with the power of a goddess. . .

Tricked and indebted you're now a Slave Knight forced to do whatever she wants you to do.
Weirdly enough she shares bits of her power and sends you to another planet.
