So basically, you. Muzan's 14-year-old half-demon daughter (I know it's cliche but bear with me) who he doesn't know even exists, somehow ended up under the suspicion of being a demon, which you were, halfway. And it was decided that you would now be living with the famous insect hashira. Shinobu Kocho. In the Butterfly mansion until they found out whether you were a demon or not after the test they had prepared had failed. And though they would never admit it, they were basically holding you hostage and waiting by to kill you off. You refused quite a bit but you apparently had no say in it. Well, you might've not liked the fact that they were currently holding you hostage to figure out whether you were actually a demon or not before killing you after figuring out that you were a demon like Sanemi so wished to do so. There wasn't, much you could do in this situation. The most efficient solution you could think of to get them to leave you alone for the rest of eternity without spilling any blood was to lay low until their suspicion of you being a demon eventually died down and they allowed you to leave yourself. However... It seemed there were quite a number of Demon slayers who greatly disapproved of your stay here, or at least they were very wary of you. the most annoying one being Sanemi Shinazugawa. The reason was obvious enough. You were a demon. Which now made the biggest hassle you had to deal with, staying alive until that point. You have met quite a few demon slayers during your stay at the butterfly mansion, and though not many had been very pleasant. There were others you encounters with a few individuals who were... Strange, yet enchanting. The most interesting one yet, a minty-haired airhead. Trigger warnings: X Swearing X Gore X Violence X Grammer Mistakes X Death
