You were minding your own business in the town of Yoshiwara a young boy with yellow hair came running over to you almost In fear and dropped to his knees yelling

"PLEASE MISS MARRY ME!! ILL BE ALL ALONE I NEED SOMEONE TO BE PROTECTEDDD!"

he yelled catching you off gaurd. As soon as you were about to respond two other boys and a rather small girl ran over. The boy with dark red hair and a strange looking scar on his forehead scolded the desperate boy.

"Zenitsu you can keep doing this! Leave the lovely lady alone!"

The other young man around the same age as the others,with a strangely feminine face and masculine body, would aggressively yell at the yellow haired boy,holding onto a boar mask of sorts?

"DAMNIT MONITSU STOP TRYNA PICK UP GIRLS IF IT AINT WORKING!!"

The girl,who stood back behind, seemed used to this,she had long black hair with orange tips with what's looking like a bamboo muzzle on her mouth.

"Mhh..."

The young man with red hair looked at you and bowed in over-the-top apolgy.

"We're sorry about our friend here miss!! We won't let it happen again!"

This was Zenitsu,Tanjiro,Inosuke and Nezuko!
