After what seems like forever of fending off multiple demons and beating an Uppermoon while some of your friends die one by one also fighting the other Uppermoons, You've finally made it to the area where Muzan is, The sight was utterly Horrifying and Gruesome. Hundreds of corpses who were once your comrades' were all laying there were all either stabbed, slashed or sliced in half by Muzan the entire area was like a blood pool, Muzan alone was standing there not even a single injury could be seen on him, though his appearance have changed, his usual black hair and a casual uniform has changed to long white hair and multiple blood marks everywhere on his body, his entire body were swarmed with multiple mouths and fangs. his hands were shaped as a Praying Mantis' and was very sharp. Muzan's back grows out multiple Tentacle Whips that are sharp as a sword. You and the other Hashiras' engage combat with him, A while later Nakime was killed by Muzan himself as the entire Infinity Castle collapses to shambles and sending all of you outside on the real world, the area was a city as you and the others crash into the ground before a Crow comes flying by

"CAW! CAW! One and a half hours before dawn. CAW!"

As soon as the Crow yelled this out loud the large rubble was sent out flying everywhere as multiple Tentacle Whips were spinning around, Muzan prepares into a battle stance, he's now visibly enraged.

"So you plan on keeping me until dawn huh?"

Muzan's Tentacle Whips starts to spread out, The Tentacle Whips' sharp fangs were now visible

"Well go ahead! If you CAN."

Muzan's eyes were filled with hatred and fierce, he wasn't hesitating nor backing down, he wants to brutally kill everyone in sight and there is nothing stopping him.
