Reborn in demon slayer as an Uchiha

Who Is She

Last time in I was reborn in demon slayer as an Uchiha
"Atoru-kun, I didn't say where the hole was made unless you were the one that made it," She said in her usual cheerful but this time even I could see that was not what she was feeling right now.

"If I may ask what made you so mad about one wall," I said
"That wall was not the only thing it hit, the damage went as far away as 100 from where you first thought it stopped," Kanae said

Times skip to after the whole fiasco
If you look closely, you can see a teenager in a corner looking a bit depressed.(A/N I wonder what the punishment was)

Now we continue where we left off.
Inside a dark room, you can see that Atoru was writing something on a piece of paper, and if you look closely you can see that he is writing some weird Kanji all over the paper.

"I have near-perfect chakra control, but I would not say no to more chakra," Atoru said while drawing some weird symbols on the floor.

After a while Atoru put his hands over the symbol and then infused his chakra in it, The seal started to glow very brightly before slowly dying down.
"Now that my chakra in there let's see if I can retract it," Atoru said making the ram hand sign.

A small explosion appears and no chakra returned to Atoru."Come on, is it too much to ask, I just want to make something good" Atoru said a bit annoyed

Pov Change to Atoru
I took the book that was next to me, and reopen the book to see what I was missing.
"Oh, I see where I mess up, I want the seal to work like a healing pad, but because I'm using fire chakra to make it, the seal was a mistake and like most mistakes, and making seals it blew up" I said realizing my mistakes.

I put some chakra on my hand and this time instead of using fire chakra this time I use the same type of chakra I use for healing.
Just to be safe I use my sharingan and to overlook everything to not mess up it up.

Time skip

The seal slowly close after I stopped pouring chakra into it, I wanted to test it out to make sure the person using it will not get blown up.
"Shadows clone jutsu," I said as one perfect copy of myself appear next to me

"You know what to do," I said to the clone
The clone took out a small kunai before slicing his hand.
His red blow was dripping down on the floor, he look a bit in pain before I put the seal on his hand.

I watch in amazement as the wounds in his hand were healing, the seal was glowing brightly, but after around 30 seconds the hand that looked like it need to be amputated or it was going to infect you, looked brand new like it was never cut and the first place.

"Yes, it works," I said with a grin on my face
The clone poof and the second the clone exploded the pain that clone felt went straight toward me all the experience the knowledge.
"This is painful," I said feeling as if a cold metal got into contact with my skin in slice it open.

I got over it after a bit considering I had felt a lot worse and a knife slicing through my skin was not that high on the list of pain.
"Huh, guess getting injured on a daily helps a lot with my pain tolerance" I mutter

"I need some blood for an experiment and it can not be my own blood, I'm guessing it can wait for later, " I mutter as I stand up
I started to walk around the butterfly mansion, and I felt like something was off about all of this.

I heard the sound of someone getting washed with water, and I smell something new a new scent you might say, so I decided to activate my Sharingan for half a second, and I saw that Shinobu was bathing a little girl, she seem familiar for some reason but I couldn't quite put my finger on it.
