Future HASHIRAS react to the PAST | AU explained in desc | KNY | kvromi !

Au: In this AU when Tanjiro became a demon, instead of going back to being a human he became the next demon king (since muzan was already defeated), the new hashiras objective is to kill him, except for nezuko,Zenitsu,inosuke and kanao they want to find a way to turn him back to a human being.(some of the breathing techniques are made by me and are not canon) ALSO the pride hashira is my friend @cuteaforrealsie 😭 Not original 🏃‍♀️
