(your muichrio also this is based off a yt i saw but i cant remember who made it only the title: what if yuichiro was ailve and a demon btw if you make it a ship with anyone except muichiro and yuichiro and yes all the dead people are alive) story/backstory: muichiro and yuichiro mum died from a disease but their dad died from a demon while he was trying to get the stuff to heal their mum but died by a demon then their mum died from the disease so they were alone and their village get attack by kokushibo but kokushibo asked them if they want to become a demon since his their uncle or grandfather yuichiro agreed but muichiro didn't agree but yuichiro asked if he could spear him then so kokushibo did then eventually muichiro had amnesia and doesn't show emotion do he doesn't remember his past and hes the mist hushira he does start remembering stuff but when he fully remembers he has panic attacks characters (demons 😈) tanjiro giyuu obanai muichiro/u yuichiro 😈 mitsuri shinobu rengoku tengen genya part 😈 kanae zenitsu inosuke kanao nezuko a good 😈 sanemi sabito kagaya makomo muzan 😈👑 akaza 😈 daki😈 kokushibo😈 douma😈 gyokko😈 enmu😈 mukago😈 rui😈
