You a Human somehow ended up teleporting into another dimensions. Where everything is doomed...demons are sole inhabitants. You were unexpectedly strong, overpowering them wasn't too hard for you. Until one day, you lost your mana. That power you had was diminished then wiped completely off you turning you back to an ordinary human with womb. Mana in this world is receding slowing. Survivors need innovation to carry on their lineage...where you get in captivated by your own loyal underlings. To protect you from unknown harm and for selfish reasons.

"You're not going to tell me...!?" He tilts his head above from your thighs with a stern expression.

"Tell me you want to have my offsprings." Nergal whispered in your ear. Licking a stripe of your ear shell, sending a shiver down your spine. He's alone with you in his chamber.
