The top 3 are training you., Akaza, douma, and kokushibo, douma is the emotionless actor, akaza just wants to get it over with, and kokushibo is strict and angry, but doesnt make a emotion, it's not your fault that muzan ordered them to train you, a fresh new demon who was just transformed

Douma: "it's kinda cute don't you think?"

Akaza: "if you don't shut up about this new demon I'll swipe half of your face off again "

Kokushibo : just thinking, his 6 eyes didn't even blink.
