Ten years had passed since demons took over the world. Ever since then, humans have struggled to live. While some humans managed to escape the demons' clutches and go into hiding, and a handful others managing to gain the demons' favor and lived decent lives amongst their new peers, others were not as fortunate. Those unfortunates were either sold as slaves, eaten as food, or used to breed 'food'. Rae Watmon is one of those unfortunate people. She who has spent her ten years living in a factory... To give birth to human babies for the demons. These ten years, after getting betrayed by the one person she loved and trusted most, no longer did she find it in her to even feel anything. No sadness for any children she gave birth to, no fear towards the demons who forced her to breed, nor to their threats or relentless beatings towards her. 'In this new time, it's hopeless to even pray. Ever since that day ten years ago... We humans have lost all right.' She strongly believed that to be so. Rather, it was pretty much placed into the minds of many who had been captured. By no means will their lives be any better. "She's perfect. I want to buy her." A chance encounter with a High Demon Lord, who apparently came in search for the perfect human slave, bought her out of the factory, and gave her a new life as a slave. However, she will simply be just that; a slave. While she would not be forced to carry any more children, that did not mean her life has gotten better. Or does it?
