My Harem of Monster Lords

Faye Young, a worn-out office worker, dies suddenly and wakes up inside the body of a plus-size princess in the Demon Realm. Armed with a strange system that returns tenfold cashback whenever she spends on her consorts, she sets out to turn her fortunes around and wins over the Wolf Demon James Lee, the Dragon Crown Prince Louis Clark, the Heavenly Fox Master Zach Yates and the Dark Serpent Priest Mason York. Her rivalry with her sister Georgia Young sharpens as Georgia schemes to seize the throne, and when Faye's coming-of-age ceremony arrives, a hidden phoenix bloodline begins to stir.
