Reborn in demon slayer as an Uchiha

New life

I woke up and looked around, all I saw was wood in a mini rengoku sleeping in the background.

Let me get my facts straight, so I didn't experience the baby phase, thank Jesus for that because I don't think I can do that, I look like I'm a toddler. I suddenly get a surge of memory that doesn't look like my own, but there are, my name is Atoru meaning sun or flame or whatever you want to put it. I also got adopted, it was pretty simple it was something about my family being close with the rengoku family, all of them died due to a demon killing them because he saw them as a threat, so if he knows I'm alive, no amount of plot or Jesus would save me from him, cause right now I look like a toddler and I'm weak as hell.

The kid that sleeps here, wait is that rengoku kyujuro Rengoku, from what my memory is telling me, he is one year older than me so he is 10 right now, considering I'm one year younger I'm 9huh, I have an older brother that I will not let die, so even if I know he gonna be a pillar in the future, I'm saving him from akaza even tho he started training in flame breathing a while back, his dad and my adopted father would not teach us the flame breathing, so he started training in secret.

From my memory so far. Shinjiro rengoku is still a Hashira but he refuses to teach rengoku anything, and me also for that matter I don't get any special treatment sad.

So I did the only thing reasonable for a human to do after having an existential crisis. I went back to bed and went to sleep.

The next day

"Atoru wake up," said a voice an energetic voice

"Ok," I said as a started to wake to see rengoku looking at me with a beaming smile, it caught me off-guard.

"Morning how was your night my brother," I said with the brightest smile ever, trying to mimic his

"Good just like always," he said with energy in vigor, I was amazed at how he can keep that personality up for so long.

"So hum would you mind if I start training with you," I said

"There would be no problem with that I will gladly accept a partner in my training "he reply

"Thanks, You rengoku it means a lot to me," I said

"You're my little brother so it's my job to watch over you"reply rengoku

"I'm taller than you and its only 1year sheesh"I reply

"But I was born first meaning I'm the elder brother, "he said like he was stating facts.

I got out of bed looked at him and said "rengoku you know today is senjuro third birthday, right you got him anything "

"I made him his favorite food," he said looking at me with the smile

I smiled back, and started walking to the bathroom when I got there I cleaned myself up and look in the mirror, I saw my reflection and I look decent .im kinda dark with black hair. I looked like a black shisui this is nice, guess I won't have too many problems getting a girlfriend.

Now I know I'm an Uchiha, having a great body and potential, I may also have chakra but I don't know how to access that yet? I may be the ninja hashira later excluding Tengen of course.

I got out of the bathroom and went to say hi to dad who was drinking.

I looked at him to say hi, but he didn't even look at me, and continued drinking, and it hurt me somehow. I know he cares, he just can't show it. I then see a picture of a woman on the wall she looks familiar. I notice tears falling out my eyes, I'm crying why would I cry over a picture but then I  remember she was my mother figure in this world, and I loved her. I wipe my tear and continues on my merry way to find rengoku to train with him to become strong. but first I went to senjuro and took care of him for a while, in after a while, I went to meet with rengoku who was reading a book on flame breathing because that was the only way he can learn it. I came to him with a smile on my face.

I don't know much of the demon slayer timeline so I did some research and found that rengoku became a demon slayer at the age of 12to13 so he must have started training pretty early like 9or10 years old and that he 7yearld older than Senjuro, I don't know exactly when the mom dies tho. I will appreciate any help or criticism.
