Uppermoon 0 tanjiro x muzan

Newly born

Tanjiro POV:
When I was four years of age I was abused by my parents. I had no idea what I had done wrong to them. Tanjiro was my name but I was called 'mistake' or 'disappointment'. So when I turned six I starred to use a katana a wooden one just to show them that I wasn't weak. When my siblings were born then were spoiled to the core. They made me sound like the bad guy so much that I lost my emotions. Until I met this guy with red cat like eyes he called himself muzan.
"You have nice eyes muzan"
Muzan POV:
I was socked that someone commented my eyes like that. I felt some heat touching my check "was I blushing" I thought to myself we talked for a bit and then he left me not noticing the earring he had on him.
Tanjiro POV:
When I got home from selling the things that my parents didn't need anymore. I heard my name being called so I turned around and saw someone. He asked me to stay in his house and then he told me about the demon that roam around at night, but I declined and went to my home slowly smelling blood. I had my katana on me I always had it on me when not by the house I ran to the house and saw my mom and four to five siblings laying there and then I was that the guy that I gave the compliment to was there killing the last one her name was nesuko and as she was a bout to be killed I asked him to stop he looked at me and asked me why and I replied with.
"Let me do it I want her to suffer the things that she has done to me in the past"
Muzan POV:
I was shocked then I smiled/smirked at him and threw the girl at his feet he didn't even flinch a bit and then he pulled out his katana and cut of her head slowly and painful. I walked over to him and he looked up at me the one thing in did not except to hear came out of his mouth and that was.
"Muzan I know you are the demon king I did my reaserch and I know that you are able to turn people into demons please turn me into a demon if that is ok with you of course"
3D POV:
Muzan was shocked that a human would have knowledge on him and be willing to be a demon. I was feeling like I had to make him a demon for some reason not sure why but I felt like it but I wanted to test something that I was not able to test for a while "memory changing" I was wanting to see what to do so I extended my nail and used my blood not even the uppermoons have this much blood in them so this will either make him a uppermoon or a demon prince but there is still a chance of him dieing but who knows. When I injected the nail into him he passed out immediately I'm not surprised. I'll find him in two days if he makes it that is I'll leave a note.
