My brother is working to hard

I need to help him

Tanjiro is being strangled by this weird looking man I think his name was hagenzuka or something I stared at him

I quickly ran over to tanjiro headbutted the man

"UGH!-" the man groaned

"Y/n that's not nice to do I'm so sorry for my sister's behavior"tanjiro said loudly scolded me then bowing to the man

"I DON'T CARE ABOUT THE GIRL WHY IS YOUR BLADE BLACK DAMNIT!!" The man yelled poking my brothers face

I huffed angrily

I'm inside this small box

Tanjiro is speaking to someone then silence

I kicked open the box fast I just wanted out of the box

I accidentally kicked a demon

Oopies

"Y/n get back over here"tanjiro yelled a little

I jogged over to him but the swamp demon snatched me

Dragging me under the puddle

I panicked kicking the demon swimming up but I was grabbed again

"So you're the one he wants your pretty for a weakling I think I'll take you as my own slave"the swamp demon 1 said

I kicked the swamp demon 1 in the face trying my hardest to get out of the swamp dome

Then I saw my brother dive in looking for me

Then he saw me his widened stare told me to get out of the swamp

I hurried up inhaling a deep breath

Jumping in front of two people I took a second glance and saw my siblings hanako.....shigeru I gently cupped the two people's face's frowning against my muzzle

Then my brother came out of the puddle swamp for some reason no demons came out I huffed in angry

I charged at my brother

"UH Y-Y/N STOP- I-I DIDN'T MEAN TO RUIN THE HAORI" my brother shouted because of my headbutt to his stomach

After my brother took the humans back to their estate

My brother stop for some dinner because hes hungry I'm sleepy but I chose to stay up for my big brother's protection

Suddenly my brother ran off

I'm confused just waiting of course he came back after 34 minutes

I huffed in angry

"Sorry y/n I didn't mean to leave you behind I just-.... never mind don't worry about it"my brother said

Later the owner of the ramen stall yelled at my brother for wasting his tasty food my brother apologized after inhaling his food like it was nothing sometimes I worry about him

We were walking I stopped grabbing my brothers haori confusing him a little until a young man came out of nowhere you can tell he's a demon from his aura

It's a demon aura

"Oh you're the demon that was with the other one right"my brother said

"Lady tamayo asked me to bring you to her and did you know the person beside you is a demon and not a good looking one to be honest"the demon boy said
