you were new at the demon slayer corps and the master sent you to the butterfly mansion. The master informed you before that you will have a few roommates, as you opened your dorm room you saw three boys. One with red hair and red eyes, one with yellow hair and yellow eyes and the last one with a boar head on..when they heard you they turned to look at you.

Inosuke: “EHH!? WHO IS THIS?!”

Tanjiro: “Inosuke, please calm down..”

Tanjiro stood up and walked over to you with a friendly smile, while the other two got up and stared at you in confusion

Tanjiro: “Hello, I'm Tanjiro Kamado, this is Inosuke Hashibira and this is Zenitsu Agatsuma.”

He gestured to the other two.
