It was the late afternoon of the fifth day when Kagami-sensei and Hiruzen Sarutobi came back from their mission. Both still had their Jonin attire on and looked to be in need of a bath and bed. “Good you are training, as were ordered. Did anything happen that needs immediate attention?” Asked Sarutobi. If he's always like this then he's quite boring. Kagami-sensei at least asks how we are.

We then had to wait for Jiraiya to come over to us. Tsunade is as often as possible as far as possible away from him. Which forces him to train away from her if she has any say in it.

“” No Sensei! “” chorused his team. Kagami-sensei looked at me, Ariha and Sakumo but we all shook our head in no.

“Very well, we have something important to tell you. The applications for the Chunin exams had ended before we got back, however, were allowed by Hokage-sama to still sign you up. It takes part in Kiri and you all can take part, that is if you feel ready. If you do, then meet me and Hiruzen tomorrow at the east gate at 7 in the morning.” We all were happy to hear this, finally, we could advance in rank. Becoming Chunin would mean almost no D-Rank missions any longer.

Both Jonin left after having said their thing and we were back alone in the clearing. “Should we stop training for today? I have to prepare some stuff, now that we have the confirmation of our participation in the Chunin Exam. I'll also have to go home and tell my family.” Ariha was the first to speak after the quick exit of our Sensei.

“I'd agree, my parents would like to hear about this as soon as possible,” agreed Sakumo. With two of us leaving it would be useless to continue. Which was why Orochimaru came to the conclusion that staying was no longer necessary. He also left without saying anything.

“Tsunade-chan, would you like to go out with me?!” Shouted suddenly Jiraiya from his place across the training field. He has been standing moments ago right next to us, but used that chance and tried to touch Tsunade's butt. She had punched him in the face and threw him away. Normally it would give him pity points, he may be a bit away 20 or so meters, but that was no reason for the use of binoculars. Especially when they were obviously more pointed at her chest than her face.

“Who would like to go out with you, Pervert?” Asked Tsunade back with a disgusted look at him. She turned to me and asked what I wanted to do.

“I'll stay a bit more and train some wind exercise. You can stay or go ahead.”

“Nu-uh! I'll stay with you Ken-kun.” Which did not mean that she would continue to train. She sat down near a tree and began to watch me starting my work on wind Chakra.

After hitting 100% in Wind Chakra Control I have started to realize that while we Ninja had control over the elements it was by far not what was truly possible. Now I see how little the people of this world are truly able to control the elements through their Jutsu.

With an affinity of 100%, which is basically impossible, I am able to directly control the very air to my wishes. I also still wonder how Tsunade even managed a level of over 90% in Medical Chakra Control.

I can control air-pressure, it allows me to fire needle-like blasts of condensed air or powerful balls of compressed air. I haven't found a limit to its strength and size yet. Only that the difficulty of the control and the consumption of Chakra increases with its power and size.

And a mistake in control during a high-level Jutsu is not simply a fizzle and a loud pop. The compressed air would decompress inside my mouth. Think about an explosion that can destroy a house within your mouth. Your dentist will thank you.

Still, that is only the beginning. I am also able to increase or decrease air-friction. Not by much right now, but if I train more in it I can increase my speed beyond my physical limit.

It is possible to change the components of the air we breathe, which can be used for quite a few situations. For example the enhancement of a friendly Fire Jutsu. After all, Fire Jutsu, supplied by the wind with a high oxygen composition will burn hotter.

Blades of wind can coat my Kunai and weapons, it increases the cutting power tremendously, but also lowers the weapons durability if they are not made for it.

And the thing I'm working on right now is the Tornado Jutsu. Well, not exactly the Jutsu. The Game system I am living by and under its rules has found ways to circumvent the power of Game Points. Sure, raising my stats or the Jutsu would be easy.

But now, at a 100% control I have a lot of doors opened to me. I have realized that I can, theoretically, do pretty much anything I want with the wind and air. But that is only the hoped end result of my training. Reaching a level of 100% allowed me direct control over wind and the very air. But that's it, the world gives me control. And at the same time no manual! It took me weeks to form wind needles that were similar to their Jutsu partner.

The Jutsu [Wind Needle] is basic C- up to B-Rank difficulty. You suck in air and mix it with Wind Chakra, before forming thin needles out of the Air-Chakra mix. Then you spit the needles at your target. The size of the needle, the amount of needles and the speed of the needles depends on the amount of the used Chakra. Control can change all three.

The difference to my attack is that I can fully control my needles. They fly the direction I want them to fly, they are as fast as I want them to be. They are as numerous as I give them power or form them to be and they are as sharp or as blunt as I wish. I also don't have to form them in my mouth. As of right now my range is ten centimeter away from my body. Any air within that range I can influence.

But then why do I have to train something when I already have the Tornado Jutsu? Just put Game Points into the Jutsu and instant full control. Well not exactly, the Max level of a Jutsu is not full control. It only lowers the time to form the Jutsu, helps you to keep the Jutsu active and lowers the costs for a Jutsu.

Great help in using and activating any Jutsu, but no help in coming up with the best use for a Jutsu. The ability to use a Jutsu like a weapon or to change the Jutsu slightly to your own use. That normally comes with the process of learning the Jutsu itself and is what first makes a Jutsu truly dangerous.

My Gamer Ability gave me a problem that is similar to that of the Uchiha's Sharingan. They learn Jutsu and skills with only a single view. But then what? Their body does not know how to move like that, their mind is not used to react to such Jutsu or skills. Maybe their whole fighting style works against it.

In some cases, they simply ignore the learned technique. Maybe going over it mentally to find a counter. But sometimes they use the new learned skill and learn it for real. They use the memorized copy to integrate themselves into the move.

That is what Ariha-chan explained when I asked her about her Sharingan and the low key trouble I could see in its use. Who would have known that the Uchiha have all learned to repress memories? It's something they apparently learn from a young age.

They learn it to repress the memories they involuntary have with their active Sharingan. Otherwise, they would quickly fall into madness. They don't only memorize the stuff they want to, they memorize everything they see. The finest dust corn on the ground up to the ant in the tree five hundred meters away. It needs training if you don't want to get crazy from remembering so much.

It might also be a possible explanation why Itachi used such a strong Genjutsu on Sasuke. He didn't want Sasuke to forget but with the training, they both had he knew that Sasuke would be able to forget almost anything if he truly wanted to.

That's maybe why he used a technique of his Mangekyou Sharingan, something which memories he too most likely was not able to forget. I wouldn't be surprised if the Mangekyou forbids you from ever forgetting. It is such a cursed evolution.

Anyway, it is similar to my own problem and she has helped me see it less as annoying and more as a reason to better myself or simply train new stuff or come up with new stuff.

And the System is helping me with that. It even prevents me from using Game Points. Only the correct use of the Jutsu unlocks a skill. That means that everything up to that point has to be trained.

Then, at some point, something like a limit is overcome and a Jutsu is generated. Like the Tornado. I can form it now without much trouble, it gets stronger the higher my mastery is and it gets less taxing. Yet, I form only one Tornado, never more.

However, that was not the limit of the Jutsu. More training will, of that I am sure, allow me to form more than one tornado at once. I just have to form them simultaneously or one after the other.

It was the same with the wind blades. I first could only form a single one and got the Jutsu for [Wind Blade]. I got another Jutsu when I formed the sixth[6 Blades of Wind] then another one for twelve[A Dozen Blades of Wind] and so far no more. Right now I can make 20.

Still, it took huge amounts of training to reach 100% in control and even more for my current mastery over the wind. and only the fact that I don't need to sleep has allowed me such a high level of control over wind.

And I need to train for it to get better, not ramble around over Chakra Control, again.

“Ken-kun, can we go? Mom said there will be roasted chicken for dinner.” Asked Tsunade suddenly. I looked up from my mini tornado in my palm and notice that a few hours have already past.

“Sure, thanks for waiting for me so long,” I said before I stood up and patted her head in thanks. She acted as if she didn't like it, but I knew she does.

“Chunin eh, finally. You think they will be hard?” Asked Tsunade me on our way back home.

I shrugged before answering. “Who knows. Maybe the other villages did the same as Konoha and didn't allow their last war class to rank up. If they did then yes it might be hard, but otherwise. I think not. The last class that became Genin finished school only last month and they are pretty weak while being the same age as us.” I replied. Those 'Genin' were a joke, some were fan girls or wannabe Ninja. They can't hold a candle to any of my class graduates.

Tsunade hummed and did not disagree with me. She too has seen how weak the graduates are in comparison. Even now she was glaring at a nearby Genin that was trying to give me a sexy wink. The wink hardly had any strength, a girl that was twelve and had no connections to me won't be interesting for me.

We reached the Senju compound and walked to our house. During the last years, I have noticed that there were not many newborns in the Senju clan. And more and more did not come back from a mission. If this keeps on the Senju will face extinction pretty soon. Maybe there is something that makes us infertile?

“Say, Tsu-chan? Do you think there can be something that makes us Senju infertile?” I asked. She frowned at my sudden question and looked at me with interest, prompting me to elaborate.

“There are fewer babies every year. There are only two others who are younger than us. None of the other Senju had a baby within the last ten years, that's strange isn't it?”

She frowned and activated a diagnostic Jutsu before moving her hand over her stomach. The glow of her Jutsu went through a few changes before she stopped it. “Well, there's nothing wrong with me. At least there is nothing I can identify right now.”

She then looked at me, my pants and then at me. “Are you serious?” I asked with a long-suffering sigh. If Tsunade gets something into her head she has to finish it. Come heaven or hell, she will get her will.

“We are siblings, we studied this already and have bathed together,” she argued.

“We stopped bathing together when you became ten, it was your decision,” I shot back. She looked at me with a strange expression. By now we had reached our home and got inside.

“Isn't the reason obvious?” She asked with a deadpan expression.

“I know why you did not want to bath together anymore. And that argument stands in this case as well, even more so. You'll have to touch me to run a diagnostic,” I said, in the middle of pulling my shoes off, followed by my coat.

“Yes well, this is different. That was then and this is now. You are right, it is strange that there are no newborn Senju. We will have to test your theory and we can start with the both of us. We are at an age where it is possible to make children.” The pervert hater Tsunade is trying to argue me into dropping my pants so that she can inspect my manhood. If only Jiraiya knew.

But whenever it comes to medical Jutsu or techniques she only has that in her head. “Fine, whatever. Can I at least keep my boxers on?”

Her expression showed that she was arguing with herself. Having my boxers on might change the diagnostic Jutsu, but she is as embarrassed as me. As I could see by the flaming red colour of her cheeks.

“That would be possible,” she said in the end. I shrugged and pulled my trousers and shirt off. Might as well get almost naked, this way I can call dibs on the shower. By the way, Tsunade was one of the few who knew about my seals. Her, Mom, Tobirama and Mito are the only ones. Maybe Kagami-sensei, but if he does he hasn't told me so. I don't know if Tobirama-Ojii has put it into my Ninja folder.

Tsunade activated her Jutsu, looked at my face, down to my crotch and then slowly grabbed me between my legs. Her face became beet red. I felt her Chakra checking my body for anything that might not be in order, going through every cell and vein.

Thank god for the Mind of a Gamer, or else I would look like her.

Still, her touch had unwanted, natural side effects...I almost missed her “is it supposed to be this big this early in age?”, but knew that calling her out on it wouldn't be healthy. Especially with being in such a vulnerable position. She doesn't have to know that I changed my hormones a little to increase its growth. No one does need to know, there is not a chance in hell that I will get a standard length of a Japanese. Never, ever.

All the medical knowledge I have needs to be used and when I am not allowed to show them openly. I want to have something out of it. Come to think of it, I can do the Jutsu on my own. Why did I not argue with that?

She finally stopped her Jutsu after who knows how many minutes and I waited for a first conclusion. “You know that you can let go now right?” I asked when she made no move to let go.

With a jump, she released her hold. Her face as red as a tomato. “Right, as far as I can see there is nothing wrong with either you or me. If it is some kind of sickness then it will manifest at a later time. I will tell Tobirama-Ojii about your idea.”

“Hopefully it was just my imagination.” She nodded, her mind not really with me. “Anyway, I take the shower first, you know, with me being already halfway naked,” I continued in a teasing manner and ducked under a swipe at my head.

Later at dinner, we told Mom about the coming Chunin exam and TobiramaOjii even had time to tell us that he is proud of us and will see us when he will watch the finals. He couldn't stay for dinner, too much work at the office.

The next morning Tsunade and I had prepared our weapons, sleeping bag, rations and other stuff we would need for a lengthy trip. If everything goes well we will reach Kiri in a month and then staying there for another month. In total, the exams will be three months long.
