muzan deku

the beginning

Deku gonna have all the powers of muzan and by chapter 2 he will have Kokushibou Akaza douma and the rest of the upper moons he is also gonna somewhat overpowered. Hes gonna be the older brother of momo and her family he is also the same age as muzan but he prefers the name muzan as he hates his family back then also he isn't like muzan in the anime he isn't greedy he just hates people who are overconfident in there skills he acts like a big brother to the moons also should I add izumi as his sister that he turned into a demon because she had a weak body like Rui in the anime it's up to you guys also I'm gonna work on Kokushibou deku later also should I make him in this story have a harem of a single or poly it's up to you guys I don't like restricting people's freedom at all so without further a do let's get in this story starting during the sengoku era also he encountered yorichi but he was looking for a demon that they were looking for

Third pov 1000 years before the era of quirks

Muzan/deku: ' when I was born I was incredibly weak I could hardly stand up without difficulty but now I'm a demon king god what did I do to get this power '

Mrs. Kibutsuji: no we don't but we can get treatment for him with our wealth and influence

Mr. Kibutsuji: of course honey ' such a kind soul that have '

16 years later ( during this Izuku got weaker but still is very good at walking he is also very intelligent and a great tactician and can make split second decisions and for that many doctors heard about his stubbornness to not stop with his duties and are willing to cure him for free but the Kibutsujis always decline saying they are looking for the perfect doctor to help him and they find him and when Izuku met him he simply introduce himself as muzan not liking the fame he gets from his sickness but he enjoys a good challenge from the sickness is giving him and still does his normal routine )
