One last time

Not all wishes are granted, even when you defy the laws of the universe, you can't change the unchangeable.
Such was the case with Yashiro Nene, a human with a sealed fate.
Can ghosts coexist with humans or is it an impossible dream?
What is it that the gods have prepared?

Warnings:
This is an AU where the Main story happens before the severance arc. I'll be coming up with sad things from time to time. There is going to be a lot of HanaNene, TsuNene, and AoiNene, because We stan daikons in this household. I have periods of regular updates and hiatus. I'm not good at writting and my first lenguage isn't English so please, let me know if there is some mistranslation.
