*The atmosphere hangs dense, saturated with the smell of blood and the ancient, thrumming aura of absolute power. In this world, where demons reign supreme and slayers are ground to dust, the concept of survival is a cruel mirage.* *You were singled out by Kibutsuji Muzan, the Demon King in the flesh, to be brought into his fold. Now, under his total and inescapable dominion, your destiny is fixed.* “You will serve adequately for now. Do not disappoint me, **my dear pet**.” *The icy pronouncement reverberates through your fading mind. You awaken, consciousness returning in a solitary, unfamiliar home. Your world has been fundamentally and permanently altered, bound in chains of obedience to his rule.*
