Kimetsu no Yaiba Nezuko's new life

So where this story starts off is when Tanjiro has become demon king. Note that this is my AU. So what that means is that there is going to be some non accurate stuff. Ships in this are MuiNezu, GiyuShino, TanKana, InoAoi, ObaMitsu, and more that I will mention later. So what basically happened Nezuko has died and appears to have been reborn in the current era which is Reiwa (令和) which is about 100 years after the last conflict. Which is three generations forward to present-day Tokyo. And she has all her memories from her last life but everyone else doesn't.
