Creation- Demon slayer fanfic

Chapter 2

I follow Tanjiro as he walks in front of me, holding the kid's hand. Apparently, we have to return him to his parents before Tanjiro introduces me to someone he knows. He said that this person might know something about me, something about where I'm from.

" You are so cool how you killed that thing  Mr. Tanjiro!" The little boy exclaims.

Due to the fact that the little boy's father was in the same profession as Tanjiro, we decided it'd be best if some random person wasn't the one to kill the demon. However, that wouldn't stop Tanjiro from trying to credit me.

" Oh I had plenty of help," Tanjiro explains.

The little boy frowns at the ground. Once we get to the house the door opens and two people rush over in a blur.

" Oh my little boy!" the woman cries.

She hugs the boy tight.

" Mama!" the kid hugs her back.

The man stands, rigidly, staring at the boy.

" Where's my daughter?" he asks Tanjiro.

" I-I'm sorry sir... the demon got to her before I could," Tanjiro responds, eyes filling with tears.

There was another kid? I couldn't smell her, nor pick up any trace of her scent. The woman looks up, fear in her eyes. She proceeds to sob, holding the boy tighter and pulling him away from the man. The man turns to the boy, brimming with anger.

" You see what happened, son? She's dead. All because she went to save you!" The man screams.

I take a step back, concerned. You should not yell at a child for the death of your daughter.

" Just leave it Akemi, he didn't know that one would come after him," the woman says, between sniffs.

" She had potential! This good-for-nothing doesn't! He killed her!" the father says, spitting in the kid's face.

Tanjiro lowers his head and stands his ground solemnly.

" You should have died! Maybe I'll make sure you do!" the man slaps the kid.

The woman stands up, protectively positioning herself in front of the scared, little boy. 

Do something.

A voice echoes in my head. It's the same one from when I first saw Tanjiro and Nezuko in the forest.

" You will never amount to anything Genki! You will always be some useless scum who needs others to be strong! You are nothing!" The man screams again.

That hit way too close to home, like I had heard those words before.

" Sir," I say, taking a deep breath.

The man turns to me, furiously. I can feel Tanjiro's stare burning into me, warning me to shut up. However, I can't just stand here and let this poor kid get blamed and beaten.

" Are you supposed to be his father?" I ask, not making eye contact.

" As if I'd consider that useless being my son," he snaps.

"Fathers are supposed to love their children, no matter if they may seem useless at a young age," I speak in a calm tone, hoping to get my point across.

" Excuse me?"

Screw it. Obviously, a direct approach is more suited for this situation.

" Maybe, the problem isn't your son... it's you, " I spit, now staring him down.

The father hurls himself at me, but I simply step aside and he lands on his stomach, flopping on the ground. Some demon slayer.

" You have no right to have a family, " I say, gritting my teeth, fists clenched.
