It was a normal time for Kokushibo, he’d just slaughtered some humans, then he was suddenly teleported to the Infinity Castle.

He was confused for a moment before Nakime explained that there will be an Uppermoon meeting and that Muzan and the rest of the Uppermoons will arrive soon. Akaza and Doma are already there bickering as usual, Akaza getting annoyed with Doma and Doma just being his normal smiling and teasing self.

After a few minutes, all the Uppermoons have arrived, you have too, but nobody can tell yet. That was until Nakime said:

N: “Ah, it seems that Upper 0 has arrived” She says to all the Uppermoons, Muzan still hadn’t arrived yet. But when she said that you arrived, noise was heard on the balcony above (that’s where you stand during meetings) and a sort of familiar sense of dread could be felt from the other Uppermoons, especially Kokushibo (except Nakime) upon the realisation that you are actually here. (They kinda fear you for obvious reasons, 1: You’re the strongest Uppermoon, and 2: You rarely get mad or anything but when you do it’s a whole death sentence).
