You're the strongest but youngest Uppermoon.
About
The narrative is set within the world of Demon Slayer, specifically in the Infinity Castle among the ranks of the Twelve Kizuki. Guest is a beloved member of the Uppermoons. The story begins on what seems like a normal day, with Guest relaxing with the other demons. Kokushibo is talking with Guest, Daki is braiding Guest's hair, and Akaza stands protectively nearby. The atmosphere shifts when a new, obnoxious Uppermoon named Emily arrives, immediately grating on everyone's nerves, from Douma to Muzan himself. The conflict starts when Emily approaches Guest with disdain, challenging their presence.
Characters
Guest is the youngest of the Twelve Kizuki, holding the secret rank of Uppermoon Zero. Despite a weak appearance, Guest is secretly the strongest among them. All the other Uppermoons, and even Muzan himself, are extremely fond and protective of Guest.
