Mikasa Pov-

"So what will we do now?" asked Tatsuya, already knowing what they'll say.

"You two will be laying low for at least 3 years, by then you will be strong enough to retreat even if you face a Kage level shinobi," Hayate said while Tatsuya looked like the textbook definition of a villain thinking something sinister.

"Isn't that too much?" I asked, knowing that if this is what Tatsuya wanted, he definitely wouldn't let them have the upper hand.

"No, you two are the future of our village, we simply can't risk it." The third Hokage finally decided to speak up.

While this was happening, Tatsuya send me a message through the system.

[Chatroom

Tatsuya- Did you notice?

Mikasa- You mean that guy sneaking underground?

Tatsuya- Yeah. He has been following us around ever since we arrived back in Konoha.

Mikasa- For real? I only noticed it yesterday while training natural energy.

Tatsuya- Well, it's not like we can do anything right now, let's just get what we can from the situation. I already planned to train for some years, so this is a good opportunity.

Mikasa- I'll leave the talking to you then.]

Everyone was observing us closely, thinking that we were dissatisfied with how they are treating us so the Hokage asked, "Of course, we won't be unreasonable to just force you into something like this. Is there anything you want?" He asked with a kind smile. 'Idiot' I thought, trying my best not to laugh.

"We would like a personal training place all for ourselves where nobody will disturb us until we come out ourselves." The Hokage just nodded, it wasn't an unreasonable demand.

"And I'll like to donate a Jutsu to the village in exchange for one," Tatsuya said with a smile.

"Which Jutsu are you going to donate?" Shikado asked, he didn't have much hope of it being something good.

Tatsuya didn't answer as he formed some hand signs before lightning chakra condensed into his right arm and the sound of birds chirping could be heard. Everyone was surprised as they had never seen this Jutsu before, Sakumo probably did.

Tatsuya turned off that bird song and said, "This is an A-rank Jutsu I created, Chidori. Its precision and lethality make it one of the best Jutsu for killing. If someone fully masters it, it'll evolve into the S-rank Jutsu, Raikiri."

'He carefully avoided the part of it requiring a Sharingan to use properly. I wonder how they'll react after realising they've been scammed.' I thought.

After a few minutes of silence, the Hokage asked, "Which Jutsu do you want in return for this one?"

"The Flying Thunder God," Tatsuya said, while everyone was shocked at first but then they sighed.

Indeed, learning about flying thunder God was considered impossible before Minato managed to do it. So they were probably thinking we'll fail. 'With his talent in Fuinjutsu and my talent in Ninjutsu, it's impossible for us to not learn it.'

The Hokage agreed pretty easily, while I was praising Tatsuya's cunning mind. We got a convenient vehicle for absolutely free.

Before leaving the Hokage's office, we were told that we'll be staying at a place not far from the Senju compound. That'll certainly be convenient.

And so, we started our training while also learning medical ninjutsu and fuinjutsu from Tsunade and Mito.

After a month of 'training' when we noticed that Black Zetsu wasn't keeping tabs on us, we started for real.

The priority was to increase our affinities with elements and natural energy. While Tatsuya was creating weird seals regularly, I was learning and improving the Flying Thunder God.

And so, three years passed.

I nodded looking at my status. I didn't do much training other than raising my elemental affinities. Especially natural energy.

'This much should be enough for the experiment.' I thought as I played with Mikasa's hair while her head rested on my lap.

"Let's recreate Wood Release," I said as Mikasa finally decided to wake up. 'Cute.'

"Why do you want wood release? It's not like you can't make something similar to the 'several thousand hands'. The one you can do is probably even more dangerous." Mikasa said.

"First, I can't use it right now. Second, the conditions are too strict." I said as I thought about what I'll do when I leave.

"That's true. By the way, Black Zetsu didn't show up for the past six months, I wonder who he is playing with." Mikasa said. Indeed, Black Zetsu stopped spying on us after I placed my 'No spy' seal around our house.

"He's probably sowing seeds for the second shinobi war." I said while thinking about the 'No spy' seal.

It's fairly simple, it absorbs natural energy from the environment and creates a barrier that doesn't allow anyone to spy on us from the outside. They can't see us, hear us or sense us from outside of the barrier. If they wish to, they'll have to enter the barrier and the moment they do, they're dead. I also created a Spy seal, which transmits audio to the user, kinda like a mic and receiver.

The Hokage gave up on sending Anbu to keep tabs on us. We just captured the Anbu he sent and handed them over to Tsunade. We did try the shadow clone cheat for training but apparently, our talents only work on our real bodies. So I just created a permanent shadow clone that absorbs natural energy from the environment to maintain itself and let it train, changing it once every few months.

Even if the Hokage gave up, Danzo didn't. Now and then there'll be a Root agent dying by my hands. It's becoming more of a refresher after training.

While we were training, some interesting things happened. Minato graduated from the Academy at the age of 7 instead of 10. I wonder how he'll meet Kushina now or learn Flying Thunder God. He now is pretty famous in the village.

With our(Mikasa's) help, Tsunade was able to create her Creation Rebirth way earlier than she did in the original. And of course, I didn't have the diamond mark on my forehead. With my chakra control, I can create the Strength of a Hundred Seal anywhere I want on my body. A Blue coloured seal on my right hand, which stores chakra and a black one on my left, which stores natural energy. With Creation Rebirth, our only problem, which was that we can't regenerate from fatal wounds is solved. And since we don't have a limited lifespan in the first place, using Creation Rebirth as much as we want isn't a problem.

Sakumo also drops by now and then to check up on our progress. Even tho we weren't directly training to increase our combat ability, it was very annoying that he can still beat us two on one like seriously, how strong are you. But now we can make him use his Kenjutsu so there's progress. With that said, I don't use my Chakra Enhanced speed or Ketsuryūgan in our fight. With Chakra Enhanced speed and the 'eye of insight' from Mikasa, my speed should be faster than the fourth Raikage in his prime, along with Raikiri, I'll be a pretty good assassin.

The friction between the shinobi villages is increasing, so the clan heads and Hayate have been very busy. Even Akito, who visited us every week reduced it to a few months. The only permanent visitors we had were Mikoto and Misaka. Mikoto also graduated from the Academy some time ago along with the everyone else.

As for the Kurama clan's Kekkei Genkai, I have no idea what's going on. My genjutsu is even better than my father now, but there's no sign of my Kekkei Genkai manifesting.

'System, show Mikasa's status.'

(ii)Exploding Human Technique]

Mikasa slacks in anything that doesn't include burning stuff. The only reason she still practices her Shurikenjutsu is because of the Flying Thunder God. I had to practically force Raikiri into her brain.

With her Ninjutsu talent, she created a teleportation technique that works within 5 meters. It doesn't require marks like Flying thunder God. She also borrowed the 'Exploding Human Technique' from me, saying that she'll create fireworks.

{A/N- An ability from Ketsuryūgan}

She also created a bunch of fire-related ninjutsu. Her 'Strength of a hundred seal' marks are the same as mine.

We both can fly on our own now, I can fly by manipulating the blood in my body, and she just created a technique similar to what Onoki used in the Anime.

Done with my internal monologue, I sat cross-legged, trying to merge earth and water chakra. It doesn't work.

I tried again and again but it failed. I used natural energy along with the two elemental chakras and try to merge them again. It doesn't work. Although the merge was successful thanks to the natural energy, it still lacks the vitality to create wood.

I used the same combo with the yang release this time. It does show a reaction but blows up. At least there's a reaction, good. I worked on it for a month before I finally succeeded.

'That's it. So the reason no one was able to replicate wood release was that they couldn't get the correct amount of yang release to use. The reason why Hashirama was able to do it may be related to his Kekkei Genkai, but with my chakra manipulation talent, I can just imitate the wood release like any normal Jutsu. But I still need to practise it more until mixing all the elements becomes an instinct.'

And after successfully recreating the Wood release, I did what any sane person would do, I spammed trees everywhere in the training ground. After the training ground was full of trees, I got rid of them before spamming them again and again until I got tired of it.

Mikasa was looking at me like some mad scientist who just succeeded in an experiment. She wasn’t wrong though.

Since the experiment was a success, I decided it was time to go out and have some fun and collect 'materials'. 'We are almost 9 years old, the second shinobi war will begin in 3 years.' I smiled thinking about it. We went inside since we'll be leaving tomorrow.

I tried to get up but couldn't, I opened my eyes to see Mikasa sleeping on my chest. I patted her head and didn't move, letting her sleep.
