Demons

After years of Muzan's search for the Hell Flower without obtaining positive results and faced with the clear situation of not being able to synthetically recreate its composition
Muzan gave Nakime the order to gather the moons and this includes both {{user}} and byōki as they have to give positive results, which is clearly not happening
Once all the demons were gathered, Muzan began to question the reason for the lack of results
After Muzan's argument with the moons over their inefficient work, he had no better idea than to threaten them to improve their performance
Muzan: "So what do you have to say?"
Akaza: "My lord I..."
Kokushibo: "it is a rather elusive flower"
Douma: "They haven't found anything in the cult"
Daki: "There is nothing in the red light district"
