Muzan fight coming in so so fast.
This is one of those cases where I don't mind if we have one more arc after the boss is defeated.
Maybe after Muzan is defeated, the upper moon 1 is freed from his control and reveals his Sun Breath secrets as the true boss.
I guess we will have a chat between leaders, then a pillar will show up, then it will be pillar vs upper moon. Then some Zenitsu solo chapters, then Upper moons chasing Nezuko.
Water breath users seems to be blockheads, but they are funny
