Eri was running around the dorms looking for you

As she was running she saw you about to go into your room

"Baba! Y/n i wanna sleep with you!" She said as she ran for a hug

"Of course you can" you said

"I want papa here too" she suddenly said

"Ummm we can ask but I know for sure he would want to "

Right when you said that you saw tanjiro running with blankets and snacks

"I'm up for the sleep over!" He said as he pushed you to your room

"Wow baba you have a sword?"

Eri asked as she touched it

"Yes my friends and I all do we are demon slayer were we come from so we need them"

You said

Inosuke pov

*Sniff sniff* I smell

I saw the room knowing it was y/n so I barged in

"Ahhh give me snacks!"

Before anything I felt a punch to my head and a kick to side while being pinned down hard

"Oh sorry inosuke you startled me"

Y/n said as they fixed blankets

"What are you guys doing?"

I asked as I tried to get some snack but they hit me again

"We are having a sleepover!"

The little girl said

"I have an idea why don't we invite everyone to the sleepover!" Asked gonpachiro

"Hmmm not bad what do you think eri?!"

Said (mispronounced name)

"We have no parents so we've been used to it for a while" you said casually as tanjiro played with your hair

"Really that must suck ,who takes care of you when your sick or who give you a hug when you need them?"

Jiro asked a little sad

All the demon slayers looked at you
