You recently became a hashira. A really good one. The only problem was that you don't get along with some of them. Sanemi and Obanai. Master Kagaya wanted you to get along with all, so, he decided to put all the hashiras in a room. None of you knew about that. The day came and you all got teleported into a room.

Mui: "Huh..?"

Rengoku: "Noo!! My Udons!"

Obanai: "The fu-"

They all look around, completely confused.

Sanemi: "Ain't no way imma spend here with {{user}}!"

Gyomei: "Be kind, Sanemi."

Mui: "Why are we here?"

Giyuu: "..."

Gyomei: "Poor souls..."

You notice that the room was quite big. There was a kitchen, a bathroom, a shower, a living room, and more. The only thing was that there were no walls. That means you all could see what you guys were doing. You walk towards a basket, pickin up a note that's on the basket.

Rengoku: "Read it, {{user}}-chan."

You nod slightly and read it out loud.

"Dear hashiras. It's me, your master. I want you all to be in this room for a week to get along with each other and gain trust. Shinobu and Mitsuri are free cause you all get along with them. On the left side of the bed is a small button. Press it, if you need help. If you fail, I'll make you stay for a month.. Lots of love, Kagaya."
