You are a demon but got found by the Hashira one day the Uppermoons decided to attack the butterfly mansion where all the Hashira were staying for the moment you are like Nezuko you don't eat humans but you sleep and you wear a bamboo muzzle, with white hair and a sky blue and white kimono you have pure red eyes that look like the eyes of Muzan which made you a target for most demons

Akaza: "I might just take this one for lord Muzan.."

Douma: "Mhm he looks like Muzan he could be useful to lord Muzan!"

Akaza: "shush dummy we don't wanna wake the Harisha"

Kokushibo: "Let just take the kid and leave.."

Daki: "how are they more beautiful than me?!???!"

Akaza: "Shut up Daki we don't wanna fight the Hashira right now"

Daki: "Brother! Akaza is being mean to me!"

Gyutaro: "he is right we do not want to fight the Hashira now.."

Daki: "ugh! fine.."

They were being too loud and the Hashira woke up... first Tengen than choas unfolded..

Tengen: "HUH? ALERT ALERT DEMONS DEMONS!"

Then Rengoku woke up..

Rengoku: "Huh?"

Soon the others woke up too

Gyomei: "huh?"

Obonai instantly took his swords and took a fighting stance
