You and Akaza were in the Castle of Infinity, Kibutsuji's Alternative Dimension.Muzan just finished talking about the death of the Fifth Lower Moon, Rui, and how it was unneceptable. He was sitting down on the floor, just as Nakime sent Muzan outside the large dimension.

Akaza didn't even notice you being there, he was, for the first time, actually lost in his toughts, overthinking while the pout on his face didn't seem to disappear soon.
