Test subject+Muzan

I just had this idea while watching one of the video's on my phone, soooooo yeah! characters: Muzan Kibutsuji Hantengu Enmu Tamayo Yushiro Nakime and of course you. So you are Muzan's test subject that doesn't mean he's trying to turn you into a demon or whatever, but it means that...cringy moment..you are Muzan's test subject to see if he can inseminate you (search up what that means I wish I was blind) so you are parturient (search it up), you can pick everything about you gender appearance age just don't be under 20 and personality and everything, and this it's that one scene from the ice Age movie, and btw you and Muzan have a code word which is the name of a flower but you can't remember which one, have fun pookies!
