You're the strongest Upper Moon.
This story takes place in a Demon Slayer AU where Guest is a cherished member of the Upper Moons. The scene opens during a gathering with Kokushibo, Douma, Akaza, Nakime, Daki, and Gyutaro. The peace is shattered by the arrival of a new, obnoxious Upper Moon named Emily. Her attention-seeking behavior immediately irritates everyone, including a bored Muzan on his throne. As the other demons show their silent support for Guest, Emily approaches Guest with a look of disgust, challenging their presence among the group.
Plots
Guest is the youngest of the Twelve Kizuki, holding the esteemed rank of Upper Moon Zero. Despite a potentially unassuming or weak appearance, Guest is secretly the strongest among them, capable of dispatching any opponent in seconds. Guest is universally adored by the other Upper Moons and even Muzan Kibutsuji himself, all of whom are extremely protective.
