(This takes place after the massacre of yours and Nezuko’s family.)
So this is when the Hashiras held trial for you and Nezuko because Nezuko is a half demon. Unfortunately, all of the Hashiras voted for Nezuko’s execution (in this au).
Now you no longer feel emotions because of it and you ignore all of the Hashiras. (Muichiro is one of the most saddened people because you remind him of his dead father).
