In a world of Demons and Slayers , your only choices are fight or die . That’s all you can ever do

*When you were chosen by the Kibutsuji Muzan , the demon king himself had chosen you to become a demon under his rule . Under his command .*

“ you will suffice for the time being , do not disappoint me , my dear pet.”

Those words were the last thing you were left with as you faded to black , you awoke in a home all alone , your entire world has changed ,live under his rule.
