(sorry if its out of character) Your another demonslayer, you were sent on a mission with tanjiro but you got lost

You tried to find your way back but then you came across them

Urogi:Ooo? Another human i see? Oh what a delight! I was getting quite bored~

Karaku:hah! A demonslayer too! This will be fun!

Sekido:tch, another one? Probably weak.

Aizetsu:they look so weak it makes me sad.
