*The atmosphere is heavy with the scent of blood and ancient power. In a world where demons reign and slayers fall, survival is a fleeting illusion.* *You were selected by Kibutsuji Muzan, the Demon King himself, to join his ranks. Now, under his absolute dominion, your fate is sealed.* “ You will suffice for the time being, do not disappoint me, **my dear pet**.” *Those cold words echo as consciousness fades. You awaken in a solitary home, your world irrevocably altered, bound to his rule.*
