"Everyone watch out!"

Flashback

We have been sent out on a mission master told us that this demon had an ability to make anyone and anything disappear out of this universe Kinda scary when you think about it

Small time skip

All of us plus pillars went to kill the demon as well as tanjiro and his friends

"Guys the demon is over here!" Called out Muichiro

We all then proceeded to take out our weapons to slay the demon, well that's until it saw all of us running at it, the demon then created a black puddle that had opened up right beneath us

Back to present time

"AHHHH!!!!!"

Everything went dark for about 5 seconds until

!ᗷᗩᗰ!

You were first to fall on the floor face first

"Ow"

You looked up to see tanjiro fall on top of your back

"Son of bitc-!"

then zenitsu fell on him

"Wait wait wait inosuk-!"

then last inosuke was on you like a dog pile

You then felt hands drag you out

"Thanks giyuu"

He just nodded

"Thats so cute!" Thought Mitsuri

"Where the hell are we!?"

Yelled Sanemi

"It seems we are still in japan " stated Shinobu

"Is everyone ok? No broken bones?"

You asked

"They are so awesome to check up one everyone!" Mitsuri whispered to herself

"Your arms bleeding let me wrap it up Mitsuri.."

Y/n said as they grabbed Mitsuris arm

"Ahhh their so kind I never even noticed my arm!"

Mitsuri though with a red face

"Alright everyone I think we should walk around to see where we are right now" said Rengoku

"Agreed" everyone said

As you all where walking threw a ally a small rat peeped out which caused Zenitsu to yell and jump and your back

" you'll protect me right!?! Y/n!"

"Yeah yeah whatev..."

Y/n said as they carried Zenitsu on there back

When you all had gotten got out of the ally you walked into a bright area with lights, cars, and many other things

"Make sure to hide your weapons"

You stated

All of your friends including you were very confused, everyone having fun as if there was nothing wrong as if no demons even existed like all your problems disappeared

Then you all spotted a ramen shop knowing you had money on you you told everyone to head there knowing that they where all freaking out about not knowing where they where

you decided to buy them some food to help relax them

As you where ordering you saw many pictures of random people with weird clothes

"Alright everyone just stay calm they will bring us the food so then once we eat we'll try to find out where we are"

You stated

As everyone was eating you saw a teen boy with yellow hair with a black stripe on it

"Heyy babe I saw you lookin cute and I was wondering if I could you know get your number " he winked at you

You all gave him a confused look

"What the hell do you mean by their number?"

Asked inosuke

With his boar head on it freaked out the other kid

"Y-you know like their phone number?" he stated back before getting pulled away by a red head with sharp teeth

"Sorry about him please enjoy your food" the red head said

"Tsk idiots " said Sanemi

"Pray for them" said gyomei

"Yo bro don't you think it's weird the clothes they are wearing, like isn't that for traditional or something like one of them has a (favorite color) one" kirishima said as denki sat back down

"Hey you punks don't be talking about my y/n like that! you guys have weird clothes too!" Shouted zenitsu while walking towards them

Right when the blond was going to do something the (hair color) person stopped them by hitting the side of there neck causing them to pass out

"Sorry about that" y/n said quickly

"Excuse me but what is this place exactly?" Y/n asked the red head

"Um where at ___ "

Kirishima replied

"Do you think you can help us get back to the demon slayer corps?" Shinobu asked as she stood next to y/n

"The what now?"

Denki asked
