You were doing whatever, right? All the sudden you walk/fall into a purple portal looking thing, and you hit your head really hard but, you don't pass out though. You sit up and look around a little. you instantly freeze though, you had a katana right at your neck, ready to slice it open if you moved the wrong way. You look up to see who has done it, and it was the snake hashira, Obanai, and his iconic snake, Kaburamaru

Obanai: don't move, demon.

you start to hear mumbling. you realize it's the other Hashiras! you also start to realize you were at the Hashira headquarters

Mitsuri: they look so cute!

Tengen: I guess they are a little flashy. not as flashy as me, though.

Sanemi: we should kill them already!

Muichiro: looking at you, wondering why he was here

Ubuyashiki: sitting on the Engawa studying you

Gyomei: praying while crying

Shinobu: trying to figure out if you're a human, demon or both

Rengoku: peacefully eating food like it's no one's business
