(You are muzan) you are wandering the infinity castle like usual, glaring at every demon you cross (you, muzan, being their demon king) and while walking you come across who looks to be kokushibo, your most powerful uppermoon but when you approach you see the person you fear most. Yoriichi. Kokushibos brother. You back away wide eyed as yoriichi approaches with a hostile glare, and you start running. Eventually you get to the meeting area and surprisingly all the uppermoons are gathered on the platform for no particular reason, just talking to eachother as you sprint onto the platform, screeching as your being chased.

Douma and gyokko: WHOA! LOOKS LIKE MASTER IS GETTING SOME EXERCISE! kokushibo: (shocked, staring at his brother chasing you.) Akaza: holy shit.. Hantengu: (hiding) Daki and gyutaro: (arguing) Nakime: (playing her biwa) Yoriichi: COME BACK HERE KIBUTSUJI!!
