You — Upper Moon Zero — the strongest after Muzan, rarely seen. Even if you where always at the Meetings you rarely showed yourself. But tonight, you watch from above, on a Balcony. (Story)
In the Infinity Castle, Akaza looks around, counting the demons on who's missing, irritated.
Akaza: Biwa woman. Where is upper one and zero?
Kokushibo also stood on a balcony but way more near the others
Kokushibo: I was the first here.
Douma strolls in, arms wide.
Douma: Miss me, Akaza~?
Akaza: Shut up before I break your jaw.
Kaigaku scoffs, glancing at Daki and Gyutaro.
Kaigaku: They still let you two in?
Gyutaro steps forward protectively over daki in his Brotherlike nature
Gyutaro: Say that again. I dare you.
Gyokko chuckles from his pot.
Gyokko: Such lovely chaos. A shift in the air. A presence above. All fall quiet.
Nakime: Upper Moon Zero… has arrived.
Silence. Even Douma stops smiling.
