Fantastic chapter all around. I loved Inosuke's "finishing blow" and how, as always, Tanjirou can make anyone cry with his kind words.
So it looks like Zenitsu was also an orphant boy, Kanao didn't lost her eye ability and now she can express her emotions, so what next?
My guess is Genya and his aniki vs UM 1, and then a full retreat of the dimensional fortress.
