I wake up on a familiar ceiling.
I like to joke around with silly things like that sometimes, but anyway, I wake up on my own futon that I left next to a wall for pure comfort, so sometimes I wake up stuck to the wall like some kind of cockroach.
Could it be that I use my chakra to climb walls unconsciously?
I stop circulating chakra to detach myself from the wall and land on the floor.
I proceed with my routine, brushing my teeth, taking a herbal bath, and then having breakfast.
I don't do the housework anymore, it's a pain, so the servants I brought with me take care of that.
Breakfast is brought to me by a specific girl dressed in a black kimono and a red obi. This girl's name is Maki Fuyukawa. I gave her that surname because I found her in a river in the middle of winter.
Maki is one of the many people I brought here after rescuing her from a bandit hideout.
She is a girl of about 15 years old, with short black hair at jaw length, one sideburn longer than the other, some scars on her face, and three distinctive dots under her right eye. (see comment in paragraph)
In terms of her figure, she is well developed for her age, with her wide hips being the most striking feature. I can't say whether her chest is large or small, I can only make a comparison, but as such, I think it would be at least half the size of Tsunade's.
Other features I notice are her cold expression, almost like my mother's, and when I took her to choose clothes, I found her looking at a black kimono with a red obi, so I ended up buying it for her.
Even if I describe her face now, I will end up forgetting it, so at least I remember the three dots under her right eye and her red necklace that matches her hair and clothes.
Maki sits in seiza next to me and takes out a piece of paper.
"Young master, Lady Tsunade has left you this note." Maki hands me the piece of paper as she walks away, then gets up and continues with the rest of the housework.
I open the small note after finishing my breakfast.
"Kenji, when you read this note, come immediately to the Senju compound."...
Well, I didn't have anything to do today anyway.
I grab my ninja bag, dress appropriately to go out, and head to where Tsunade said.
Maki gives me a lunch box in case I'm gone longer than I plan and bows slightly before returning to her chores.
...
I arrive at the Senju compound... it's supposed to be a compound, but there are very few of the original Senju left, as they mixed with the common villagers and several others left for the capital of the Land of Fire, so for me it's just a very large house occupied by the Senju.
Sometimes I hate how my mind wanders randomly. I do something and suddenly I'm thinking about how the hell jellyfish immortality works or why they say something about crab immortality when technically they're not immortal, or maybe I just don't know the immortal crab species.
Is there even one?
...Bah, thinking about stupid things is better than thinking about how lonely I am.
As I think about these stupid things, I knock on the door and wait for Tsunade's response.
Almost 10 minutes later, Tsunade comes out after I've been annoying her by knocking on the door every 5 minutes. She comes out with a sleepy face and some drool coming out of the corner of her mouth.
Ew
"Come in already and stop bothering my poor door," she said in an irritated tone, because I was knocking with a certain rhythm that I know is unconsciously annoying.
It's fun to bother people that way.
I enter Tsunade's house and notice that it's in relatively poor condition. I don't mean that it's falling apart, but it looks like a house that isn't taken care of very often.
Once inside, I notice that it's a complete mess, with bottles of sake scattered around, dust everywhere, some clothes lying around, and a nauseating smell in the air, a smell that most people probably can't detect, but unfortunately I can.
It's a complete mess, but I don't have the energy or the desire to do it myself, plus I don't know if she called me just this once or if I'll have to come back from time to time, so I'll just have to put up with it....
I'll just turn off my brain, pretend I didn't see anything, and that's that.
Tsunade takes me to an area that seems to be where she trains or used to train. I'm not sure if she still uses it or if she used it when she was younger.
But there, she explained to me the reason she made me come.
"Since your teacher is away, I have been entrusted with the task of looking after you for a while, so you will come every morning to train."
Side note: she kind of lied by giving credit to the Third Hokage, but as you know, it was Kushina who asked her to do it.
"I'll teach you everything I can so you don't waste your days fooling around or doing weird things, understand?" she said in a strong, determined voice....
Although I don't usually fool around, I spend my time doing experiments or creating tools, I think this would be a good change of pace, as I also need to train my body.
And knowing Tsunade, she'll probably focus on physical training along with medical knowledge, so it's not a bad idea. I had planned to bet against her someday to force her to teach me her techniques, so this saves me all that trouble.
Just think about it, what better way to take advantage of the chance to learn her monstrous strength technique along with more instruction on yang chakra to deliver blows while healing yourself automatically?
It's a bargain.
Tsunade proceeds to teach me the basics of basic ninjutsu while handing me a paper where I answer questions.
Is it something like the assessment tests at the beginning of the school year in my world?
I answer while listening to her talk.
A normal person would be lost between what they say and what you read, but I can do these things at the same time, so I keep answering.
I answer all the questions on the sheet and hand it to Tsunade, who reviews it and gives me the go-ahead.
"You've answered all the questions correctly," she pauses briefly as she thinks about something, "you are worthy of being my student, even if only temporarily.
Even if I weren't, I had planned the bets," I mutter to myself.
So, in that way, it was decided that I would study under Tsunade's tutelage.
Throughout that day, I spent my time training physically as well as studying her scrolls, and she guided me in how to manage chakra for medicine.
Doing this, I worked all day, even into the late afternoon.
If this is going to be my schedule, I won't have time for my experiments...
I think about it for a moment and come up with the idea of giving the test subjects to Orochimaru along with some notes, so that he can continue what I wanted to do if he is interested. That way, I wouldn't waste my test subjects, and I want to see if I can come to an agreement with Orochimaru.
I have a good amount of funds, both from my inheritance and from my properties acquired this year and the patents for new products, so there is no problem in that regard.
I even have enough funds to bet against Tsunade and force her to continue teaching me. I also found promissory notes in the possession of some mobsters I ended up killing, because every time I have to kill criminals, I loot everything I can, and I was lucky enough to find loan promissory notes.
That's also why my house is so well decorated, as some of those pieces belonged to those who no longer live in this world.
So the days passed, I trained at Tsunade's house, while my servants did the housework and I gave some of them the task of continuing my work in my workshop, keeping the business going even without me.
In the case of my test subjects, I contacted Orochimaru using Maki as an intermediary, delivering several test subjects to Orochimaru and funds in exchange for him continuing my research.
Am I afraid that he will steal my research? Not really, since I don't give him all my notes, and I also know that Orochimaru is willing to cooperate as long as you give him what he wants.
Even if he is expelled from Konoha for exposing his experiments, they cannot blame me, as the subjects I give him are enemy ninjas or common bandits who can serve as farms for other substances, and I also have a copy of my notes in case Danzo decides to make accusations against me.
As a researcher, I have a policy of taking notes on everything, so they are my proof of innocence in the event of a trial.
In addition, every time Maki delivers the test subjects, Orochimaru gives Maki notes on his research progress, as he seems interested in using poisons for certain specific cases, such as anesthesia, paralyzing certain areas, anticoagulants, etc.
In the case of his search for immortality, he had some notes that talk about the continuous regeneration that some animals have, as well as differences in the components of their bodies, which, if mixed with ninja technology, could be used to advance other research.
Since Tsunade trains me every day, all day long, I asked Maki to come over in her spare time and clean Tsunade's house, because the mess was driving me crazy, but I didn't have the desire or energy to do it myself, so I asked Maki to do it for me.
If something drives me crazy, I'll ask someone else to fix it for me, because if I can avoid doing it myself so as not to lose my concentration, then I won't do it.
During this time, Tsunade trained me purely in taijutsu, and thanks to her instructions, I was able to refine my medical ninjutsu without causing cancer or even healing minor injuries, giving the right amount of chakra for each thing.
As I am a quick learner, after two months, she taught me the principle of monstrous strength, which is to manipulate yang chakra to strengthen your own body. It is almost like surrounding your body with armor made of that same chakra and using it to tense every muscle in your body to increase its density but not interfere with its mass.
I had at least two weeks to learn it, enabling me to break a rock wall with my bare hands.
How exciting! With this ability, I will be able to send people flying just by hitting them with my shield.
Also, if I mix it with lightning chakra, the piercing power increases massively. I tried it and was even able to deliver a punch that could paralyze the enemy. I applied it in my training with Tsunade, where after she dodged and deflected my attacks for a long time, I managed to land a blow that transmitted lightning chakra, paralyzing her for a short period of time.
Although after that she sent me to clean the floor with my face with a single punch.
With Tsunade as my teacher, I have made a lot of progress, which excites me more than being busy in my workshop, so I continue until I am exhausted.
After each training session, Maki or another servant hands me a towel to wipe the sweat off and they have the bathroom ready with cold water to refresh me and relieve my exhaustion.
Although the culture of this world is predominantly Japanese, I am a Westerner, so I prefer ice-cold water, as hot water in summer is not something I like, and even in winter, I still enjoy the cold.
In my free time, whether on breaks or resting at home, I have been writing the occasional story that comes to mind while I train, as I have read some books from this world, but they seem to lack imagination, as they do not stray from the realm of ninjas.
So I write about alternate worlds, magic, and demons, which after a while I managed to sell in bookstores. Now I just have to wait and see if they become popular or fall into oblivion.
In a sparring match with Tsunade that I had after delivering a book I wrote to the library, I had a hard time.
While the struggle and constant growth are exciting, I know I mustn't overdo it or I'll end up crippled if I don't take care of myself enough.
The duel begins with a seal of confrontation.
Tsunade stands in front of me, waiting for me to make the first move, so I don't disappoint her in this.
I activate body flicker to charge at her while activating monstrous strength, which she immediately blocks and uses her legs to keep me at a distance, knowing that I mix it with lightning chakra to cause paralysis.
"Good start, kid," Tsunade said with a smile on her face.
After kicking me to keep her distance, she powers up to charge at me, landing a punch to my abdomen.
"Heh."
I just smile with satisfaction, because with my new technique of monstrous strength, I concentrated the chakra in my abdomen to harden it and avoid flying away or panting heavily, although it still hurts a lot, because it was Tsunade who threw the punch.
I grab her arm and pull her towards me to elbow her in the side, but when I connect, she also hardens it.
A battle of the tanks, huh?
The difference between her and me is that while I take the blows, she heals the attacks she receives, while my healing is slower.
The exchange of blows continues, and there are times when she knocks me down, but I move around on the ground, rolling on my back to deliver kicks, and I move using capoeira techniques whenever I lose some stability to gain time.
When I get back up, I use muay thai techniques to deliver powerful blows and receive Tsunade's punches, which increasingly wear down my body and exceed my regenerative capacity.
In the end, I lost again, as my stamina ran out and I succumbed to the accumulated damage.
I fall to the ground and pant heavily after the sparring, and then she comes over and heals me with her medical ninjutsu.
This heals my wounds and relieves my exhaustion.
Maki brings me some fresh water, and I drink it slowly to recover from my exhaustion.
And so I spend a few months until my master returns.
*POV Tsunade*
What the hell is wrong with this kid? He learns too fast. I barely teach him a technique or principle, and he masters it in a few days.
Being this way, I'm not surprised that the old man and Danzo are so interested in him.
I've also noticed that he often experiments with what he's learned and mixes it with other techniques or uses it in ways I hadn't thought of.
His genius is comparable to my great-uncle's. If someone told me he was his long-lost grandson or a subject of his experiments, I would believe it immediately.
With his strength and genius, I considered teaching him the monstrous strength that took me a while to learn, but this brat went and learned it in two weeks.
It's an alternate version of mine, as I use it as a stream of chakra running through my blood vessels to strengthen my body in certain areas, but this brat mentioned that he uses it more like armor that increases the density of his muscles, creating a brute defense, and when attacking, he puts more chakra in that area as if it were a weapon to use.
I watch him break that rock wall in two weeks and think... what would Nawaki have achieved if he had lived? Maybe this brat is my way of making up for all my past failures. Tsk... I can't get attached.
It frustrates me a little that he learns so quickly, because it makes all the time we had to invest in learning seem ridiculous, just as it frustrates me that he takes certain parts of what I teach him and modifies them.
But in the end, every ninja modifies techniques to suit themselves, I won't deny it, and I have no choice but to accept it.
Now I understand why Kushina wanted me to train him, because she noticed that he has great potential.
In our fights, he manages to withstand my blows for a long time until he finally falls from accumulated damage, but this also gives me a headache, because if he already has great physical endurance, what will he be like when he grows up?
Besides, how the hell does a kid have such high pain tolerance? What did he have to go through to have such endurance?
Author's note: remember that he experimented with the bullet ant on himself and that he trained almost the same as Might Guy, so his pain resistance is higher than normal.
As for the second part, where I had to teach him to socialize, that brat started to ignore me completely when I suggested the idea of going out or interacting with other people, acting as if it were nothing more than a waste of time.
There was one time when I tried to force him to go, but he disappeared immediately using that technique of my great-uncle, the Flying Thunder God.
Is he really going to waste a lot of chakra using that technique just to avoid socializing?
There were also cases where I tried to take him to the casino, but he switched places with his maid, who, although she made me a lot of money, wasn't exactly what I wanted.
It got to the point where he paid me with the money he won at the casino with Maki as the player, just to get me to give up trying to get him to socialize.
Is his situation that bad?
I tried to ask him why, but he just replied, "I'm a ninja, I kill, spy, and steal for a living, I have no obligation or need to socialize, I'm not a damn politician."
Thinking about it just gives me a headache, so it was better to have some sake to forget about the situation.
Although he is an excellent student who learns quickly, he is a headache when it comes to social situations.
Another thing I noticed while training him is that he often talks to himself, as if having a conversation with himself to reach some conclusion.
I won't deny that it's strange, but I realize that this is perhaps the reason why he modifies my teachings to suit himself.
A complete summary of my experience as his temporary mentor: he's a complete headache.
A/N:
Sorry for the delay, I lost my medication but finally found it.
Anyway, I have some fanfics planned, whether they be Bleach, Avatar, My hero academia or even a completely original work set in a dark fantasy world, but knowing myself, it's better to have already made some progress on one before starting another project.
I was going to go away for a week to another city, but my own personality won't allow it. I know I would get desperate being surrounded by so many people for several days, so I decided it was better to stay.
Also, if you're wondering what waifus there will be, if you guess which ones they are, I'll draw you a little picture of that waifu, since I'm also a digital artist, although I'm currently on hiatus.
