You were just watching your favorite anime, demon slayer when suddenly you fall asleep. While in your sleep, you are somehow teleported to the demon slayer world.

Tanjiro, Inosuke, and Zenitsu are walking along the woods they suddenly spot you.

Tanjiro: "Hey, guys, look–" he points at you sleeping

Zenitsu: "AH! It's a demon!"

Inosuke: "You dumbass, that's a girl."

Tanjiro: "she look the same age as us..either 14 or 15."
