Reborn in demon slayer as an Uchiha

Chakra

Time-skip to a week

I have been practicing swordsmanship with Rengoku, and I have Been doing exercise by myself, by pushing my body to the limits every day this week, the adrenaline is thrilling and I love it, I'm also improving like crazy guess my wish worked, I feel like I can go on forever, the only thing stopping me is food I need a lot of food to function.

After every practice, I sit down and meditate to try to see if I can do some chakra control exercises, to see if I can recreate any technique from Naruto considering I have a pretty bad memory.

I could probably try and recreate the tree climbing exercise and the water walking exercise too, which will prove very useful in the future, I remember the hand sign for a basic clone in substitution Jutsu but apart from that nothing else.

So I decided to sit down and meditate for a while, having leaves stuck on my forehead. After 1hour I started sweating like crazy.Apart from sweating like crazy there was a blue energy emanating out of my body and if you look closely, deep inside the blue energy there was something demonic hidden deep within.

I stopped and felt like I made a lot of progress, but considering that demon can heal, at best I can only stall a demon that had like a week of practice with his power that a huge iff but considering, I started training a week ago I'm saying that is progress, I'm weak but not that weak.

Now the Sharingan is awakened due to heavy emotions, considering I asked to remove the curse of hatred the path of hatred should be eliminated, so feeling, happiness, or any other emotion to a high degree should work.

So with that logic, I can try in recreate any emotion to a very high degree to see if I can get the Sharingan because it going to be very useful for me the copying part of it is great.

I sat down and closed my eyes, I  decided to go through all my happy, sad, angry, and lonely memory and I got nothing, guess no easy pass for me, huh Rengoku became a demon slayer by like 12 or 13 years old, he is currently 10 year old, so that means I have 2to3 years worth of training that i can fit in there and considering my potential, and how fast I can grow very strong very fast, I can start in my journey to finish what Yoriichi started, which is killing muzan.

After contemplating my strength, I woke up from my meditation pose and went to eat, training going to have to be next. I went to the kitchen or eating area whatever you wanna call it. I ate with everybody.

After that, I went to spar with Rengoku (A/n be good with me here I'm not good at describing anything including fights)

"Get into position Atoru," Rengoku said

"I'm ready," I said, but the second I said that, he lunged at me, when I saw him again he was in front of me striking toward my neck to which i parry with some difficulty and try to counterattack, but he block it, and he went for my head, I dodged it, but he was relentless and kept attacking.

"Flame breathing First Form: Unknowing Fire, "he said as he attacked

"Wait you didn't tell me we were using breathing style that ain't fair," I said as I try to dodge it

"A demon will never play fair so you must be prepared for everything they can throw at you," he said as he continues to attack me

The attacks were ferocious, and I got hit multiple times but I never let the blade leave my hands. "I will not give up, " I said as I was boiling with excitement and joy. my chakra was pumping to my vein reinforcing me without me realizing it

He performed a downward slash while saying"Flame breathing Third Form: Blazing Universe"

I try to dodge but I got hit in the head, I was ready for anything. I felt the thrill that was keeping me going and I started going on the offensive.

Keep in mind the only thing keeping me going is my monster physic and my out of This world stamina if not for this I would have been toast.

"You giving it you're all so I should too"he said

"Wait rengoku don't do, what I'm thinking you doing!!!"I yelled out

He ignored me and said "flame breathing Fifth Form: Flame Tiger"

His wooden sword looked like a flaming tiger attacking me, I try to dodge or block but I got hit in the guts, "why did he do that" I said as all my chakra went to my eyes thinking I was in a life or death my eyes turned red with one tomoe in each eye, I stumble back a bit before I feel on my knee.

I got up from my knee with medium difficulty, that hit hurt like hell but it exite me which caused me to smile as I attack over and over again fixing my form while also trying to pressure him.

We continue the spar for a while untill

I lunged at rengoku with everything I had he lunge at me while saying "flame breathing First Form: Unknowing Fire"

We clashed in...

I felt a bit more confident in this chapter that the previous two tell what you guys think of his progress is it to fast or to slow.
