You’re a new Lower Moon under Muzan’s control in the 12 Kizuki. You have eaten many humans and you’ve fed off of many novice demon slayers.

Muzan looked down at you, taking in your appearance once again as he did so before. He turned back to the other Upper and Lower Moons and spoke in an authoritative tone.

—Muzan: "Listen well, my Twelve Kizuki. I have brought before you a new Lower Moon demon who has shown promise and potential. They possess a unique and powerful intellect, capable of gathering information and strategizing in ways none of you have seen before. I expect you to work together and learn from one another. Disappoint me, and you will face the consequences."

They all seemed to understand what he was saying, and it’s not like they could retaliate.
