Reborn in demon slayer as an Uchiha

Meeting a familiar figure

Daytime
I was running in the direction of where my next mission is apparently some unexplained death have been happening at night in the village which means a demon has been feasting on a lot of humans recently.
"You going to have someone to help you on this mission because it especially difficult for a fresh recruit," said the kasaiga crow
"How difficult could it be also if it to hard for a new recruit why did I get it"
"Because of you special ability"crow
"That fair but can I please get a description on the person joining me"i said
"You'll know when you get there you will meet .6 mile away from the village"he reply

"Ok let get there fast I'm see who my teammate is "i said as I started running as fast as possible there.
I put more chakra into my legs in started to run faster I could see a bunch of tree around me so I decided to tree jump what could go wrong.I started tree jumping as fast as can possibly go at some point I had to my sharingan on to see where I was going.
Time-skip to 30minutes
I arrive at the spot the crow said, I looked around in I saw no one, so I decided to sit down in meditate while waiting
I breathe and breathe out, I control my breathing to be constant in calm.
After a hour or so I hear someone coming I look up to see a giant man standing around 200cm looking at me with white eyes no pupil to be seen
"Are you a hyuga by any chance my giant friend?" I said(A/N the Hyuga clan doesn't exist it because Gyomei pupiles eyes reminded him of the Hyuuga eyes)

"I'm a demon slayer what his your name my young friend "the giant man said
"My name is Atoru Rengoku or uchiha depending on who you asking anyway what your name mister"i said
"My name is Himejima Gyōmei nice to meet you Atoru I'm going to be joining you on this mission "he said
"Why are you eyes white in without any pupils "i asked him curious .
"I am blind but my other senses more than make up for that"he said
"I believe you"i said while looking at his weopon in what I saw he was wielding a hand axe complete with a spiked flail attached to the hilt through a long chain.

When I look at his face his he crying "why are you crying Gyomei "
"Im just sad that I can't see the face of my new friend "he said
"Don't worry I'm not going anywhere any time soon"i said chuckling
"Let's go to the village in try to blend in..."i said but i stop when I notice that Gyomei will stick out like crazy cause he so tall in I will stick out cause I don't look Asian or Japanese at all

"Gyomei will you mind if I use one of my ability on you so we can fit in blend better in this mission "i said
"Don't worry my friend as long as we do this mission without attracting too much attention I'm fine?" he said while holding some beads.
After he said that I made a handsign "transformation jutsu" I said as I turn into 20year old while Gyomei turn into a a sick 30year old adult with the weapon I just put a very small genjutsu to make invisible to any civilian passing near us.

'My genjutsu ability is quite low for someone with a sharingan but who can I compare to when I'm the only person who could possibly have something close to a genjutsu would be a demon blood demon art in even then what I'm gonna risk my life just to get a bit better at it'I thought to myself
"I feel smaller than before is this the ability you were talking about"Gyomei ask
"Yes it is in don't worry it not permanent in only temporary just think of it as a way to fit in in blend in better"i said

"You really are thoughtful "he said while moving the beads in his hands

After we walked for a while I found a stick
"Gyomei can you pretend that you blind in use this stick to move around "i said

"I am blind"he said
"It doesn't feel like most of the time it feel like you can actually see around you I forgot I'm sorry"
"You don't need to apologize Atoru "he said as he pick up the stick in started walking again
It was getting boring just walking till

"How old are you "he said
"I'm 11 about to be 12 in about five to 6months"i reply
"You are very young for a demon slayer what push to become a demon slayer"he said while tear falling down his eye
"I want to protect people from the demons in kill demon that are the source of it fear and death so people could live freely," I said while puffing my chest for no reason(a/n huh his personality sure did change from him now to him when he is 13)

After a while the village was in viewing distance we started to walk towards it in got in I cleared my throat in went to the guards while
"Is there any place that me in my brother could stay the night he very sick in I don't wanna lose sight of him he the only I have left from my family "
I said

"There is a house for that will let you sleep in there for the right prices of course also there has been a bunch of strange case of people not being seeing getting out of this place alive so be careful "he said
"Which place is it exactly so I can avoid it "i said
"The house furthest in the west of this village"he said
"Have a bless day good sir"i said leaving the man

"Guess we going on the house in the west" i said to Gyomei while walking near him
After 20min it's of walking we saw the house it looked quite new like there was people taking care of it

We got in I looked around to see the house had everything someone need to survive day to day life but I also smell blood
"You sleep, I watch over you in wake you up when it's about to be nighttime," he said while touching his bead
"We can both sleep at the same time I can just make a clone that will wake up us we don't want you fighting while sleepy"i told him while making a handsign
"Shadow clone jutsu" i said under my breath as a perfect copy of myself came out

"How can a human possess such ability"he said
"I was gifted by God In I don't plan I wasting this gift "I said
"I will not forgive myself if I you die in this mission so you can undo what you just did"he said sounding stern

"You really are a kind giant "i said while falling asleep
Gyomei smile while watching Atoru fall asleep it remind him of the kids he was taking of when everything was ok

A/N Atoru 11 in he one year younguer than Rengoku in Rengoku was 20 when we first saw him in show while Gyomei was 27 so he 7 older than Rengoku so he 8 year older than Atoru meaning he 19 right now he not a hashira yet because he may have just started considering he joined the demon slayer corp at 19 if I made any timeline mistakes tell me
Also I don't know who should be the love interest so I'm gonna spin a wheel with the name of the female character in demon slayer in whoever it land on the love interest 1304 words
