Fics like Heart of Peace | A Kny x reader insert |

A world and body not your own. Demon slayer, a simple enjoyment in your last life. Yet here you are. Is there a chance to save all your favorites? Life and death are around every corner, and you become the one factor unaccounted for. You know the future of every major fight. Do you have time for romance, time to get to know the people around you that you adored in your world? Your knowledge needs to be kept hidden, except, what if you forget to account for the Demon King himself? When you become the common face in every major failure, always waiting for an exact moment, like you know it’s going to happen, you can’t expect Muzan not to take notice. A target rises easily on your back, but not an order to kill you. Will you survive and save your beloved characters turned friends, or fall into Muzan’s grasp dooming them? At the moment, there is no dedicated love interest, all characters over 18 are considered possible love interests. (Demons with child-like appearances or who act like a child/turned as a child are not considered) Reader will be referred to as she/her and female anatomy will be mentioned. This is an Isekai type story. might end up Rengoku x Reader focused
