To Be With You Forever (Douma x Kotoha)

"Muzan or not Muzan?"

{Today is Muzan past and present Pov}

Hi I'm Muzan Kibutsuji but actually I got reincarnated to an alternative universe of the original anime that is Demon Slayer I was a fan of the anime and I felt bad for Muzan because he only wanted to live he became irritable maybe because of how he was treated I watch how we were given a little of his back story he was desperate to live and it made him into an annoying person. I can understand him somewhat after reading the manga the fact he was barely living every day he could die anytime but he kept on pushing just to be healthy and the doctor that turned him a demon is a mad man he had intentions of using Muzan as a tool after perfecting him a tool with no will but Muzan with his inpatient self killed him before he could fully turned him into a monster though he got so obsessed to walk in the sunlight how desperate he is to just do one thing but it's not a good reason to kill and people though he may have turned demons like Gyutaro and Daki and I'm happy he did but his obsession to be this kind of perfect demon is so much and I started to wonder what if he was slowly going insane because they're are voices inside demons heads to make them do this monstrous things and I was right

I was any kind of adult work, eat, go home, sleep and repeat I was like a robot till I got an illness I felt so vulnerable and angry how people pitied me and looked down on me and then I watched Demon Slayer I was captivated I watched every season and read every manga and I got to like Muzan he is somehow similar to me and when I learned his past I cried out thinking how much people treated him just by being borned sick because I thought about how parent's in Muzans era only use they're children for political issues and using them to marry off just to high statued family, all they thought were appearance and I observed how Muzan was secluded being an embarrassment to the family because of being how he is when he also didn't wanted to be who he is then when I closed my eyes and open them again I was inside Muzan Kibutsuji's body after he was turned into a demon I felt so hungry and crave to eat meat and it's human flesh but I bit myself going back to my senses as I fled far away from human society then memories just flowed into my mind and I really was right I was reincarnated into demon slayer but this time Muzan didn't kill the doctor before he was turned the doctor got into an accident that is after I had learned the truth and am now in the present after telling my grandson my story

Though I can't get used to it sometimes how I can see what the demons I turned to see and feel they're emotions I feel such connections is this how Muzan in the original went through? Feeling every emotions like an overwhelming waterfall I got used to it after a few centuries I really didn't ate humans and actually I am able to hear demons thoughts  when the first time I've met the first demon that was an error with no rationality but it was just he doesn't have any will he was like a berserked animal I heard his thoughts he was begging to be killed and that he didn't want to hurt me he couldn't talk but I could hear his thoughts I tried to make him rational but it was useless the only option was to kill him but I remembered how in Demon Slayer the only way to kill a demon is to use a ninchirin sword or leaving the demon in the day to burn but I was in a vulnerable spot on both choices It was the beginning of the night and I'm not that strong Muzan was a beginner demon when he got turned I must eat humans to get stronger and the demon Infront of me back then ate many humans but I was a bit stronger because I was the Demon King also the Villain so I chose an option I read in some fandom stories of the anime I ate his heart but it was not a good solution so I ate him whole it felt disgusting but then he really died and I could here him that he finally got his wish that was death after he got turned into a demon he killed his family and killed people he loves

I thought if I can change Muzans faith so I went and tried becoming a good demon this alternative universe of Demon Slayer was so different just by how Muzan didn't kill the Doctor the Doctor had created many errors and after so many times I felt kinda happy being a vigilante kind of demon where I set error demons free and saving more humans though it's disgusting how I need to eat the demons to kill them I got used to it and then I tract the doctor I won and that was when I had the ability to turn human to demons I know I can do it all this time but I wanted they're consent I worked hard but that stupid doctor made to many demon errors and one was somewhat like me but crazy ass like Original Muzan many things changed instead of me killing Tamayos family and forcing her into being a demon I saved her by turning her into a demon which she consented to and her family was killed by demon errors and I made a deal with her since I know she can turn demons back to humans because of how intelligent she is, since Muzan had to die in the original so every demon is gone I thought of instead of killing demon errors what if we turn them back to being human like how Tanjiro was like this demons when he became a demon

Me and Tamayo were now somewhat friends she was so different from the original she was cheerful and energetic not like the original modest and mature but it doesn't matter, I am now not alone then we met Yorichi and dang he really was scary Muzan was not overreacting but thankfully Tamayo rescued me she really is the best we became friends and I was glad that in this universe Yorichi and Kokushibo as in Michikatsu didn't became like the original Kokushibo he and Yorichi are great brothers he really is a good older brother here it was cool being with all three of them fighting side by side we tried to help join sides with the Demon Slayer Corps but they disagree and saw Yorichi and Kokushibo as traitors and kicked them out for being friends with us but the two didn't care and Kokushibo was a badass like he swung his sword at the headquarters and the headquarters was dang like sushi sliced and Yorichi as well did the same and damn me and Tamayo watched they're breathing and was amazed I was so greatful reincarnating into a demon because only demons can see sword breathing humans who does not wield the breathing can't see it and dang they're swordsmanship and duality are so great the corps regret ever kicking them out they said names to us but couldn't come and fight knowing how powerful the two are I mean the sun breathing was where breathing techniques were derived from but Moon breathing dang it was also cool I tried to learn them but it was an epic fail but oh well

We of course had a great journey together traveling and defeating the ass demon that doctor created kiling and turning other demons back to humans and some wanted to be demons to be protectors which people mistook them as mythical creatures and I mean demons are mythical creatures as well and the demons I've turned into that cannot be like me and Tamayo not needing human flesh and blood we turned them back to being humans as Kokushibo that we turned into a demon said he also wants to stay as a demon to stay in check with some demons and in this universe he always visits his family he didn't had six eyes when visiting them the theory was right Kokushibo manipulated his body to have six eyes to be able to see his brothers moves more well when they both spar when practicing. Yorichi didn't want to be a demon which we respected he really is a good man till the end I know how he will visit a family then in the future and making a friend that continued his line of sun breathing and thats where the main character shows up after few generations. Later after this parting but we all promise to adventure together again after our break of hunting since we aren't the only ones subjugating demons and after like a decade we met Kokushibos family know of him being a demon but accepted him and Kokushibo introduced us I am so happy to be an Uncle and Kokushibo is a great father here as well as a husband we all stayed till Kokushibos son grown and started to live on they're own while we stayed to mourn his wife's death she was really a kind soul

Yorichi was now on his 60's but it seemed he didn't change we continue our promise and finally emerged victorious the bad demons were gone but we were still not welcomed by most of the world we know that so we secluded ourselves but they killed one of my own and the connections I felt with every human I turned is so strong I felt losing an important part of myself I now understand a mother's gief why do you ask it felt like that to me because I felt a thread of myself being cut and I felt it like a stab to my heart my body going numb my children were being killed and they never fought back because of my orders to never hurt humans they're really good demons I then had enough since the world so want me to be the Villain I originally am why not. I discussed it with the three and they agreed because they also had enough Yorichi, Tamayo, Kokushibo know that not all humans were bad but it felt unfair that they deem us evil when they see us in bare eyes that we did it all unlike the corps that originally was open to good demons because that was only in Kagayas era but the master of the Demon Slayer Corps at the time was abusing his power we aren't letting any of our kin to be killed any longer I let them lose to protect is to attack and defend when needed that's what I gave as my final order letting them do as they wish and I do not regret it now I'm Muzan Kibutsuji the Villain of Demon Slayer I accepted that fate but then how surprisingly I am Inosukes Grandfather and he had brought the boy that Yorichi reincarnated to well that's my theory but it's firm I can feel Yorichi is back his finally back to us Tamayo will be so glad will visit her immediately after she comes back
