A Certain Jutsu

Shisui body flickered out of the restaurant immediately after he told Mizuki to follow him, clearly in a hurry to show him whatever he had found.

Mizuki: "I'm really sorry Anko, but I got to go now"

Anko: "Don't worry about it! Dinner's on you though, also you owe me another meal after this."

Mizuki laughed and shook his head as he reached for his wallet and paid the bill.

Anko got the leftover dumplings they didn't eat packed up to eat later, saving them for an in-school snack for when they got bored.

. . . . .

Mizuki used chakra to enhance his speed as he jumped from building to building as the urban cityscape gave way to the forest.

Mizuki rushed through the now-familiar beaten path, until after ten minutes he reached his destination, the training grounds that the boys used.

Glancing around, Mizuki found that he was not the only one there.

Guy was practicing his taijutsu, kicking a log as he slowly muttered to himself "266...267...268..."

Obito was also there, he was practicing his fire style as Mizuki noticed a large ball of flame travel across the lake.

However, what surprised Mizuki most was that Kakashi was there as well, he was practicing using his saber, creating flashes of white light as he swung it.

Shisui: "Finally! Took you long enough to get here!"

Shisui appeared out of seemingly nowhere, using the body flicker technique to teleport into the clearing that the boys used for sparring.

After a couple of minutes, all five boys were gathered, Shisui was facing the other four who were all sitting in a large tree overlooking the clearing.

Kakashi: "What did you call us here for?"

Kakashi asked impatiently.

In the year that had passed, despite Kakashi's genius performance as an academy student and genin, he was still being held back, causing the boy's patience to wear thin

Shisui: "Calm down, calm down"

Shisui replied casually.

After pausing for around 10 seconds for dramatic effect, Shisui then continued.

"I may have just found the most OP jutsu.."

This caused Obito to nearly burst out into laughter, only to look around and realize he is the only one and promptly quiet down.

Kakashi now had a curious glint in his eye as he looked at Shisui "Explain"

Shisui sighed, "It would just be easier if I showed you"

Shisui placed his fingers in a cross, creating the hand sign for one of the most iconic jutsu of all time.

Shisui: "Shadow Clone Jutsu"

In a puff of smoke, a copy of Shisui could be seen right next to him.

Seeing this, Kakashi let loose a light sigh before getting up, clearly slightly disappointed.

Kakashi: "Thanks, but I already know the shadow clone jutsu"

hearing this, Shisui sighed slightly before facing Kakashi.

Shisui: "Worth the shot on the off chance you didn't know it, sorry to waste your time"

With those words, Kakashi looked at Shisui with the closest thing to a smile that he could muster, before turning and leaping away, vanishing as quickly as he came.

Upon Kakashi's departure, things quickly returned to normal among the group.

Obito looked at Shisui with confusion

Obito: "Huh? It's just the clone jutsu?"

Shisui smirked as both he and his clone weaved hand signs

Mizuki: "Katon: Fireball Jutsu"

Two fireballs then shot into the clearing, much to Obito's surprise.

Obito: "Wow! That's waaaay too damn OP"

Shisui: "Not just that, but the memories of the clone are given to you when it dissolves, also they are actually physically here so they can also use Taijutsu"

Obito: "What's the big deal about the memories"

Shisui: "It can allow you to train twice as fast and also could help with recon missions"

Obito: "Oooh"

Even with more intelligence compared to his anime counterpart, Obito was still a bit naive sometimes.

Shisui: "Yup"

Shisui: "Anyways, I'm going to teach you guys how to cast it"

Obito: "What?"

Guy: "Really"

Mizuki: "Thanks!"

Shisui then grabbed a large scroll off of his back and opened it, revealing the contents, diagrams, and writing explaining how the shadow clone and multi shadow clone jutsus worked.

Apparently, Shisui had managed to get the Uchiha Clan to give him the scroll to practice under the condition that he kept it secret.

Obito: "Huh, then shouldn't you be not telling us?"

Shisui: "It's fine, just don't be running down the street shouting that you know it"

Everyone then gathered around the scroll, reading through its contents relentlessly, double and triple-checking to make sure that they got nothing wrong.

Demonstrating a level of studiousness that, if seen by their instructor by the academy, would make him scream in surprise, it was the complete opposite of what they were like in class!

After reading through the scroll several times, the boys got up and began to practice the jutsu.

Mizuki quickly realized how difficult this jutsu was to cast, It took him roughly forty-five minutes to cast the fire style jutsu that Shisui taught him.

But now?

It took him that much time just to create anything, before this all that happened was a puff of smoke with nothing coming out.

After these forty-five minutes of hard work Mizuki was graced with a breakthrough; failed clone.

A singular ragdoll looking clone that appeared almost identical to the one Naruto created in the anime when he tried to use the clone jutsu.

Mizuki sighed as he shook his head. It would be a long night. But it would be worth it by the end, mastering the jutsu that every Naruto fan pretended they had at least once.

________________________________________________________________________________________ (Guy POV)

Whilst the others were practicing this newfound jutsu, Guy went back to the log he was kicking in order to improve his physical strength.

He could still technically perform ninjutsu, unlike his student counterpart.

Although, the caveat being that had virtually no talent for it, and he knew that he could only perform the most basic of ninjutsu after working for months, let alone an A rank jutsu.

Although this disparity did not bother Guy at all, contrarily it made him feel more motivated.

He could still use taijutsu after all.

That's why he had to work even harder! So long as he worked harder than them, he would eventually prevail!

He may only use Taijutsu!

But so what?

He would work harder than everyone!

He would be stronger than everyone else!

He would be a genius of hard work!

That was the ninja way!

HE WOULD LET THE POWER OF YOUTH EXPLODE!!
