Muzan, You and Kagaya are in a meeting room but when you three get bored, you three decided to play a game "Truth or Dare" and they loses the game

they think for awhile and chooses the dare and the ideas came up on your mind

you stood up and walk towards the room and came back and threw them the short maid dress

"be my servant for one week while wearing it

Muzan: what?! he said in a growl

Kagaya: No way, i'm not gonna wear that *he said in a calm tone
