Ninjutsu

--POV Kakashi--

Jumping through the rooftops of civilian buildings, I quickly signalled for Weasel to take over for me.

My shift of guarding my sensei's son is finally over and I can now get back to the Shimura compound. Before I go back though, I quickly make a pit stop at the Konoha library as I need to pick up a few ninjutsu to teach Raiden this week.

I've already left root without causing any conflict which was pretty great as I think Danzo doesn't seem to think my value is worth it, but it makes sense though I've been pretty useless in most missions.

When Raiden makes it to the academy I will retire from Anbu and become an elite Jounin and maybe train some academy students.

'Meh I'm too lazy, I'll just fail all of them and read my icha-icha books. I heard that a new book will be released next week.'

Walking through the entrance I quickly flash my ID to the Chunin as I make my way to the E-rank section.

This section holds a lot of daily life ninjutsu but that isn't what I'm here for.

Looking for the higher tier E-rank ninjutsu I pick up three of the basic academy ninjutsu that Raiden will need to learn eventually.

Putting the three scrolls in my storage scroll I proceed to make my way to the D-rank jutsu section.

Going through the rows I start to scan the rows with my eyes until I finally find it.

[Body Flicker Technique D-rank Ninjutsu]

Taking the scroll and putting it in my scroll I head back to the front desk of the library and write down what I took and soon after leave to make my way back to the Shimura compound.

--POV Raiden--

Walking through the empty hallway of my house I start to do my warm-up routine that Kakashi updated for me recently.

'I'm supposed to learn ninjutsu today which will help me a lot.

I'm not sure if everyone knows the true value of these techniques, but before branching out to other ninjutsu I will master at least the body replacement technique. This is to be able to instantly ditch attacks and the clone jutsu to leave after body flicker basically copying Shisui.

I've already planned out what I wanted in my ninjutsu arsenal since I was three, I had extra time to think about it so I thought it through. Of course, without much knowledge, my questions were answered by the Copy Ninja himself.

()()(Ninjutsu List)()()

[Three Academy Jutsu E-Rank]

[Body Flicker D-Rank]

[Swift Wind Wall C-Rank]

[Water Release: Water Formation Wall C-Rank]

[Earth Release: Earth-Style Wall B-Rank]

[Fire Release: Great Fire Wall Technique B-Rank]

[Shadow Clone B-Rank]

[Danzo's Wind Release Jutsus]

[Rasengan A-Rank]

[Chidori A-Rank]

()()(End)()()

The four elemental wall jutsus were more complementary if anything. Being able to defend myself using all four elements is just a good move set to have. And importantly the earth wall helps me with creating barriers in battle.

Its best use will be for allies though, as if I can't dodge the attack. That just means my walls wouldn't make a dent anyway. Sometimes in some situations, winning the fight is to have numbers and keep the advantage.

I need to worry about the smaller fights now rather than regret it later.

No matter what, having a teammate die is always a loss.

Having the numbers advantage in the lower-level fights nearly guarantees the win.

Of course, though the priority is myself...

The most important being the earth wall with uses like needing to close out a sightline with a barrage of shuriken and kunai being thrown.

For the [Transformation jutsu], I mean I'm a shinobi...

I need that shit.

[Body Flicker] and [Clone] are used in tandem like Shisui for great mobility and maneuvering. Especially paired with my [Swift Release]. On top of maybe getting Danzo's wind release just to help my own Ninjato's and offensive ninjutsu repertoire.

[Rasengan] for the chakra control and just having the move in general as an ace. It's a good trump card to have plus the potential to improve it further.

Such as making a small [Rasengan] and using the lightning release to make it invisible. Basically an invisible bomb. Other than that the [Chidori] also is a good ace, with different applications.

Even more, it's possible to add [Chidori Stream] and [Swift Release] making a railgun with a kunai.

'So many options.' I giddily thought.

[Shadow Clone] will be more tailored to training. 

With its apparent use, being able to 2x or even 4x my training progress every day is too good to pass up randomly.

My weakness would be a lack of sensory abilities, there's always a chance of getting assassinated with my talents. There's not much else that could threaten me in that department. Either way, I have a speed kekkei genkai.

Improving reaction time could be the deciding factor whether I live or die.

Walking outside I meet up with Kakashi who is sitting down reading his smut books again.'This guy bro I can't.' I think to myself.

"Hello..." I say trailing off at the end. The copy ninja seeing my squinting eyes just sighs which made my smile twitch a little.

Watching the man, he takes out four scrolls which should be the ninjutsu I'll be learning today.

"Maa, maa. Raiden why are you looking at me like that~"

Hearing his overzealous tone, my face expressed no amusement at his expense.

This bastard not only couldn't teach for shit but needs some therapy.

At this point, I may as well ask for a root agent to teach me.

'Actually, that doesn't sound too bad. Only if I struggle initially.' Making up my mind it was time to look at the scrolls.

"Just give me the scrolls." I deadpan.

"I'll only give you one of the E-rank Justus to start. I'll give you the next one when you get the hang of your choice. Here, take your pick." Nodding at his words I walk up to the man and look at the labels.

[Transformation Jutsu E-Rank]

[Body Replacement Jutsu E-Rank]

[Clone Jutsu E-Rank]

[Body Flicker D-Rank]

The choice wasn't too hard from my perspective. 

My theory knowledge of chakra was pretty much complete due to finishing all the academy work before doing any ninjutsu. I've trained in the leaf exercise for two years now and it should be somewhat doable.

"I'll start with the [Transformation Jutsu]."

The logic behind it?

Body flicker can be saved for the last being D-Rank, Replacement is a precursor to the flicker and clone justu will be used with the flicker. Better to separate these things beforehand.

Grabbing the scroll, Kakashi pockets the rest.

Class: Supplementary

Dog > Boar > Ram

Most commonly used to disguise as another person, it can also be used to become inanimate objects. This technique depends on little chakra but decent chakra control and imagination.

()()(End)()()

'Let's take this back to the compound.' I thought to myself already thinking of ways to easily learn the technique.

The first is trial and error.

...

A few minutes later back in my room, Bird was currently here because I asked her to help me with a few things. Looking at the newly added mirror and with Bird not wearing her mask.

It was time to practise some justu! 

"Bird sit next to me," I command sitting in front of the mirror. Bird complying, expressionlessly sat completely still which would have irked me before.

It felt more, "normal" now.

Slowly my attitude towards her was getting more demanding.

After getting a decent look at her and imagining her face a little, I do the three hand signs.

Dog > Boar > Ram

*Poof!*

In front the both of us was a face resembling Bird's but more comical. It lacked any sort of details with the skin colour looking a bit off, while the smoke cloud produced was a lot so the used chakra was a bit too much.

The head shape looked a bit bumped up as well.

Sectioning out the details after, I experiment with how much chakra to use.

After seven uses I was able to get the smoke to be as minimal as possible, while still covering me somewhat. 

There goes a quarter of my reserves...

'Hmmm, let's get a better look at her face.'

She had some dark circles under her eyes, some nose stress creases similar to Itachi and a dark mole under her left eye.

Doing the seals again I was able to get down most of the details on her face. The looks of a grown woman on a Childs body was a bit disturbing, but hey we need to make gradual progress somehow.

Looking at the mirror, our faces looked more like we were siblings but it was better than failing the just outright.

(Bird POV)

'How terrifying...' The thought went through my head watching Raiden quickly adapt to using the ninjutsu.

The extremely fast pace at which he is learning is unnatural.

First, the quick adjustment of chakra use which usually takes a few weeks to months, is done in a couple of attempts. The next step after that was getting the shape of my face and general looks correct.

Done instantly.

Looking into his empty eyes through the mirror, the young heir was unnerving. His emotions constantly changed from joy to seriousness in an instant. He was always distant and cold towards me and I couldn't understand it.

Raiden was more "relaxed' around Kakashi...

Could he sense her lack of talent compared to his?

No.. That's not possible.

I've been with him his entire life.

I'm merely a "person" in front of a future monster.

Every time I would try to get closer using the common root methods, he'd naturally give me a voided look. His eyes reflected nothingness, it seemed he didn't even acknowledge my existence, that I was even alive.

Just a mere servant.

"Bird, tilt your head."

His voice rang out in a monotone way. Instinctively tensing up, I stiffly move my head.

Raiden proceeded to use the [Transformation Jutsu] just a few more times. After the second attempt, he perfected the face shape, by the third, the hair was integrated, by the fourth details were added and by the fifth, he was able to use it effectively enough to pass the academy's standards.

'He is beyond what a prodigy is... I understand why Danzo-sama wanted him to be raised.' I revere.

It was an honour being his caretaker.

Raiden Shimura.

The future of this world.

[POV Raiden Shimura]

It took two days to learn each of the three E-Rank jutsus of the academy. The first day is to get the general idea and the second is to perfect it as much as possible. The [Clone Jutsu] was simple once I learned the transformation jutsu as they have a similar way of needing "imagination" and a careful need for detail.

The replacement jutsu worked by already having an existing item needed to replace myself with. Commonly kids in the academy would have a storage seal of a log which would be summoned, and the cloud from using the jutsu would disguise the jutsu.

Of course, better applications of this can be seen in the anime with the Land of Waves arc. Where Kakashi faked his death and didn't use any smoke.

The second part of the jutsu worked like a spring. The more chakra the further the distance, but because of needing to replace myself with an item, it limits how far I can spring-shot myself.

So when I finally learned about this it made the D-Rank body flicker way easier.

Unfortunately, there hasn't been any progress in removing hand seals.

For that, I just need more practice and start doing tree climbing.
