The Darkness Hashira (demon slayer females x Male reader)

Prologue

*Y/N was a typical teenager who is Hella perverted, lazy and loves video games. He's doing bad at school and doesn't have many friends, he's also out of shape. He was adopted by his aunt and was a huge dweeb*

                         - Y/N POV-

I was walking down the street while looking through my phone

"oh, a new episode of demon slayer came out, gotta watch it" I said excitedly

I entered a website where I watched demon slayer, then I clicked on the episode as it started

"man... I wish I was in demon slayer world too Y'know? Maybe I'd be super strong demon slayer, or a demon... Maybe I'd get a good looking milf as my wife" I said... To Noone In particular. I was used to talking with myself since I didn't have many friends

As I walked and thought of how cool it would be to live in a demon slayer world, I walked through pedestrian crossing and didn't notice a truck speeding on the road, I looked up from my phone

"oh shit!" I yelled, fear encasing my body as I was frozen... It was too late to dodge!

I turned to look at the drivers seat 'wait, nobody is driving this thing... Can this be the mighty truck-Kun?!' i asked myself eternally as I got hit with the truck

And then it got dark... Real dark, I saw a light approaching, it was trippy but when I opened my eyes... I was a child?!

Yes, that's right, I was a child, held in the arms of a kind woman with brown hair, red eyes and  a white haori, who I presumed was my mother, she gently patted my head and kissed my forehead, I couldn't help but giggle

"aw you sweet little boy, look at you... Not even crying, so calm and cute!" my now mother said and held me in her arms

Then I saw a manly face poking from the side of her, he had black hair and red eyes also, he wore a nobleman outfit that was black, he was probably my father

" well... It appears he inherited my good looks at least" my new father said as he got elbowed by my mother

"don't say it as if that's the only good thing about him" mother scolded father

"I apologize" father said, from first glance I could tell he was a huge simp for mother so he was super polite in front of her

My eyes then got heavy and I struggled to keep them open

"Aw, looks like our sweet child needs some sleep, go ahead little one" mother said with a warm and kind voice, making me even more sleepy and so I fell asleep

Now why don't I just skip the part where I was a baby? Probably for the best.

So 4 years later I basically grew accustomed to my new family, father was rather nice and wise and mother was kind and caring. Since I had memories of my old life, I was a very quiet and behaving type of child, wanting my new life to be great since I was born in Japan apperently. In 4 years, I learned how to read and write kinda, it was hard learning such a language but i never stopped trying, my parents where impressed by my 'learning skills', they didn't know that deep down, I was now a 20 year old man in a kids body who was very untalented and will only be complimented at childhood.

But to my surprise i noticed that I had better strength, speed and durability then even some other teenagers in this world.

Also for a kid I sure slept a lot, so my parents called a doctor and he explained that I had a new type of condition that made me sleepy all the time, I guess that's a pain in the ass for me after finding out my buffs.
