Failure-Intolerant

“	This is my single question for all of you: Why is it you demons of the lower ranks are so utterly weak? You shouldn't be satisfied merely being among the Twelve Kizuki. That is only the start. You must devour more humans, gain more power. THAT is the path to becoming useful to me. For over a century, the upper members of the Twelve Kizuki have remained unchanged, and it has always been those members who have disposed of the Hashira. Meanwhile, how many times have YOU been replaced?	„
	~ Muzan Kibutsuji admonishing the lower ranks of the Twelve Kizuki, before mercilessly killing them, after Rui's death.
