Reborn in Naruto world with demon slayer powers

Academy was never this easy. It was just that I was lazy, lacked concentration, and was forever distracted from doing anything, which I never knew I was. But... I do not know if it is because of chakra or breathing technique, but things got easy, a lot, if I say so, to the point where I do stuff on instinct. My day is full of chakra usage, even to the point where I use chakra to walk in my house.

Training in the academy was not worth doing, I do not know why they even care about doing it if it is so useless. Yoriichi's training has been better than academy training and it includes mostly kenjutsu ( demon slayer style), taijutsu (mixed martial arts ) and bukijutsu (mixed weapon arts).

This bukijutsu style I am going to use is going to be improved from what people know, as I will introduce new weapons and styles. It will be more interesting as there will be more improved taijutsu (The author has researched fighting weapons and techniques and it is going to be interesting. Dattebayo!! )

I made no rivals because I would rather not… when anyone wanted to spar with me I overpowered them to the point it looked like the opponent did not even learn taijutsu. Yes! I humiliated them and they did not see it as I never showed I cared about the fight that much. 

Neji Hayuga, was quite the practice dummy, he could see just how my attacks came to hit him he even for some reason changed his fighting style from the gentle fist, I also changed my style and use my original style, my every strike and defence was dangerously unpredictable, in a short period it was my defence created openings in the opponent which he sometimes noticed and my follow attack was dangerous enough to kill or cripple the opponent. 

I even started using clones and transformation at one point. That got some viewers a little trauma as it would seem his attack hit me and my limbs were torn off. That's one tricky and new way to use basic ninjutsu. I did get scolded for using such a trick… I mean, we are going to become a ninja what else do you expect if not death and gore?

I did make quite the friends and it did not include Neji because he is my practice dummy. It was quite a fun time when we did not have classes. Obviously. Camping was one thing that helped me understand a lot of things, I got my first kill a boar everyone asked to share even sensei but I did not i tried explaining that I needed it but they understood it after I made a bet of eating the whole boar and as I ate the 20 kg boar... They were shocked, I mean I am Yoriichi the demon slayer what else can you expect, I won 50 bowls of ramen. Ichiraku ramen was very famous and I am a record maker they never expected me to eat 100 bowls of ramen. You would ask how I ate that much. I created a technique that turns food into nutrients with the help of chakra. I also got a little help in developing this technique from big-boned people ( Akimichi ).

It has been a lot of time and I am in the last year of the academy. It just so happened that I got to know that my family is rich. And I have a Mountain and for some reason, it has a small iron vein which only the clan members know, There are only 20 or so people so no one will know that there is an iron vein on the mountain not even Danzo because it was later found it had one… My father to whom I talk because I have a reason to do and it is important. He is the kind of father who is more of a father, like he won't smile even if he is happy like I will ask for pocket money. He did give me pocket money but his facial expressions were like he was a wooden log whenever we talked or met.

I tried not to talk to my mother about the academy and training or anything that included fighting or anything close. She barely knew anything because if I told her then she would start saying things like I should not do this and that and attend the academy and nagging like any mom does but increased with the power of chakra. 

It was fun going to the mountain and enjoying the sunset, it also increased my lung capacity to the point where I could hold my breath for 15 min. Even I did not believe it when I came out of the water after 15 minutes to make a time check, it did not even feel like I was holding my breath, It was maybe due to natural energy making me strong.

I know that I can master any chakra nature so I did some thought on it and decided that I would master it all and become the sage of six paths without those weird eyes that look like an onion interior. I did think about getting those eyes but I dropped the idea as I would not like to stick someone else's eyes in my head just to get some shit powers which use all my chakra. How did Danzo stick those eyes in his head and hand? Just thinking about those eyes and hand on me gives me a shiver… its creepy and I knew that it would be a constant reminder.

Illusions, are the world of nonphysical matter where the mind is the limit to the creation, the temporary existence you create, unreal, non-existent and full of holes. In this technique, you use the spiritual energy part of the chakra to control others' chakra and deceive their 5 senses or mostly visual senses and control their possible actions in the created view of others and the best way to escape this is to disrupt the chakra and make it under your control again or reset your five senses. which would be difficult for those who have good five senses another way to do it is to have such control over your chakra that it is almost impossible to make your chakra controlled by others which would be at the level of kage or six paths sage, I a new way of using illusion, by beaking the innermost part of ear 'cochlear' and damage their sense of direction. 

The breathing technique is the best thing I could have asked for it increased my control over my subconscious part and I can change my blood flow, stop my muscle instincts, ignore pain, and open the limits of my physical body and it gave me a mark on my head of the demon slayer, everyone in my clan was shocked as it had been a long time since anyone had the mark and they were happy for me and felt a bit bad at it would damage the body a lot as it unleashes the full potential and if not taken care of properly take away my life force in fights before i got to even know.

It was a double-edged sword, but I got all the information I needed to know about it and I was for some reason accepted as a genius and the hashira without my permission or reasons. Not that I cared about it but it did get me a lot of benefits. I also got reprimanded. About what I was doing in training that it would get me a mark… not that I told them anything. Parents can be a little restrictive but in a good way. I am happy as I did not become insane like Kakashi, he is a different specimen, I don't know how he is even working and didn't go on a killing rampage… maybe a few friends and relatives are keeping him being himself. 

I once saw the hidden mist jutsu in the clan library or bookshelf… I tried learning it and it was easy with mist breathing and chakra sensing, I can use it in a better way I tried using illusion clone transformation substitution and every basic thing to make my mist style just as better as the water style but not as better as the water style.

My water style seems to have almost been mastered, with only 2 styles remaining the 10th form and the 11th form. I don't know how to erase all my killing intent, battle intent, fighting spirit, or the presence or stop it as it would be the same as fooling itself of being non-existent and I know that if this one works then I would get a little access to sage energy and become strong enough to defeat anyone, this one would use not just intension, training, mussel memory, and dullness of senses as it is a selfless state in which I would be seen as an illusion but if stray attack landed on me I would let it hit me as I would not care and it is dangerous, a perfect technique with a flaw mostly no one could think of.
