Death of a Nuisance

"Bunshin no Jutsu!"

In the Academy, Naruto yells as a cloud of smoke poofs beside him, as another Naruto emerges, but the look of its expression was, 'dead,'

"Fail!"

Iruka shouted as he watches Naruto restlessly brushes his head while holding a tense smile.

It was the time the plot started, I have various ways to alternate the worlds fate, but mostly just relax,

"Naruto failed? looks like we graduate early Hayabusa-san, looks like our future Hokage will be late,"

Shikamura spoke while he had his arms on the table, previously dozing off,

"Yeah, Naruto will definitely graduate anytime soon anyway,"

I replied while we watched the show.

Now I watched Naruto failing — next Mizuki will make his move after this.

...

School finished as everyone graduated, Naruto swayed on a swing viewing everyone cheerfully chattering to their parents,

"Don't worry Naruto, You will graduate,"

Naruto groaned to my spoken words as I stood beside him, Naruto responding with a reply,

"Yeah, I will, I just need to try again,"

Speaking the words, he places his head on the rope of the swing, then I spoke

"I have to go now, want to walk together?"

Naruto answers tiredly while he glanced at me,

"Nah. I think I'll stay here for a while,"

swiping his hands at me while he closed his eyes looking away,

"Okay, see you later,"

"Yeah,...Later,"

I left, but before Naruto's silhouette disappeared, I quickly jumped to a near building — getting up the roof, running back to the academy,

"Plan one, remove the nuisance named Mizuki,"

I said the sentence as a smile grew from the face of my expression, a habit when I'm about to kill someone.

When I got back, Naruto already left strolling down the path to his home, then there's Mizuki in front of Naruto.

They went off to talk on the Balcony, I just watched them silently, as usual, I wasn't serious, but put a mental note that if I failed, even if a very tiny change, it could cause alternate development for the Universes future, but me failing?

Laughable — that would never happen.

Later Naruto finished chattering with Mizuki, it was already night, Naruto went to the building where Naruto found the Forbidden Jutsu,

'Kage Bunshin no Jutsu,'

a Jutsu, the Creator, Tobirama Senju.

"Haha, found you! Now, time to learn it!"

Hearing Naruto talking to himself, Naruto left the building with the scroll behind his back,

"Oi, what are you doing here,"

Ah, the Shinobi is here, I believe that my appearance change some bits of the future so I have to be extra careful, so I planned to knock out some Shinobi's who are patrolling the night,

"Ah, sorry, sorry, I was just—,"

I instantly moved, moving in an unusual way, I was able to control his mind by using my body movements, then causing an illusion for a second as I disappeared in his vision, I appeared behind him, striking the back of his neck, causing him to fall unconscious,

"Heh, I'm just going to purely use my body as a handicap, until I meet someone stronger,"

the Shinobi won't remember a thing, the mind-controlling movement I learned from my learning times as a Ninja.

it's rather difficult to master, only Sensei mastered it over his years. me? It took me a day.

Normally, a hidden ninja village from my world just trains to do things stealthily to gather intel as a few defence martial arts, like Bujinkan that commonly associated with ninjutsu (real ones).

But my village is different, we specialize more in executing people and multiple people effectively.

Extensive strict training, renowned for assassination, training our bodies to the limit, manipulating the bodies physique to a godly-level, the capability to pour out hydrogen igniting it as our body turns on fire without damaging it — another way, we were able to be resistance to the hot and cold as well as control the temperature of our body.

We still train in espionage, surpassing than all the other Ninjas moreover all, but we focus more on becoming the perfect assassins, perfect Ninjas, we were named, 'Death Shinobi-no-Mono.' (SNM, it just means Ninja, as well the meaning, stealth person)

...

I followed Naruto while he went to the forest to practice the Jutsu, as I hid in the trees watching the show to behold,

"I should have brought some food, well, it doesn't matter,"

I watched as I sat on a branch of a tree, observing.

...

Hours have passed — Naruto is already sweating from the training, watching — I thought of leaving to get some food but before I was about to do that, Iruka was already there, he was gasping, catching his breath —

"I— finally, found you,..."

— While Naruto responded with an insult, "Hey! I found the nose bleeder!"

Naruto points as Iruka bellows,

"Idiot! I found you!!!"

Iruka shouts at Naruto as Naruto who later rubs his head, good thing their relationship is still the same, I like Iruka and Naruto's connection.

Few words were exchanged with the two as the conversation was still going,

"Hey, Naruto, where did you get the scroll,"

Now the talk progressed,

"Mizuki-sensei told me about it as well as the place! —

— He told me if I show you this skill to you, I'll definitely graduate!"

Naruto's obliviosity is still there, I then watched a bunch of kunai's getting thrown at them, watching it a few more times, I can finally relax, but I still kept watch.

At the climax, Naruto used the technique.

...

The morning was up as the night went down, I stood up the branch,

'Now it's my turn.'

...

"Get in!"

A guard of the KSCF (Konoha Strict Correctional Facility) threw Mizuki in his cell,

"Agh—!"

He was thrown in while the bars of the cell closes, then Mizuki got to the corner, then expressed his rage,

"That brat! I will get my retribution! First I need to escape this hole, then—!"

Before Mizuki finished a word, I appeared,

"Hello, Mizuki,"

I smiled,

"W—who are yo—!" Stopping his words again with mine,

"They can't see me only you, the Genjustu pretty neat ey~, but I don't have much time, so drink this,"

I shoved the drink at his mouth as he struggled, I continued to speak,

"It's poison, it disperses after you die in your body, removing every evidence of how you die, I made the poison myself~,"

I watched him struggled, fear grew in his eyes, the same eyes the people I poisoned,

'ah~, the nostalgia,'

I stood there, watching as Mizuki slowly dies... Then he departs the living as his dead body laid on the floor, as for myself, left the scene.
