Naruto Shadow Mage

*Poof!*

The Shadow Shuriken technique flew out, and Koshino used his newly developed jutsu and his app to achieve a flawless victory!

Under the restraining power of the Shadow Shuriken, just as Uchiha Yuno finished his seals and was about to unleash the Uchiha Clan's signature Fire Style: Great Fireball Jutsu, a shuriken suddenly shot out from Koshino's hand. The shuriken carried the binding power of the Shadow Sewing technique, pinning Yuno's shadow and immobilizing him. The interrupted jutsu backfired, causing Yuno to cough up blood!

"Yuno!"

Seeing Yuno spitting blood, Uchiha Kin, Uchiha Gin, and Uchiha Hi all looked panicked, deeply concerned for their companion's safety.

But as the three Uchiha youths' gazes were fixated on Yuno, Koshino suddenly changed his hand seals once again!

"Shadow Strangulation Jutsu!"

*Crack!*

*Crack!*

In another swift change of seals, the shadows under Uchiha Kin, Uchiha Gin, and Uchiha Hi mutated. Dark, shadowy hands climbed up and clutched their necks, turning their faces purple in an instant.

A little more force from Koshino and these three Uchiha youths would undoubtedly meet a tragic end!

However, at this moment, who was paying attention to the four unfortunate Uchiha youths?

Almost everyone's eyes were on Koshino the moment Yuno spat blood!

In three moves, he had taken down four of the Uchiha Clan's top young talents. What an astonishing feat!

Even Shikaku was among those stunned. No one had expected that the four-year-old Koshino, using only the Nara Clan's secret techniques, could defeat four elite members of the Uchiha Clan. So, when Koshino claimed his flawless victory, everyone fell silent. Those who had doubted him felt their cheeks burning as if they had been slapped in the face!

Only Fugaku Uchiha's expression kept changing, his gaze towards Koshino growing increasingly hostile.

But as he suppressed his anger, reminding himself that he couldn't publicly attack Koshino, Shikaku's sudden exclamation broke the silence!

"Koshino! Was that jutsu you used just now one you invented?"

"Oh? The Shadow Shuriken? Yes, Shikaku-uncle, I invented it myself!"

Smiling at Shikaku, Koshino, having used the Shadow Shuriken in the match, openly stated, "Shikaku-uncle, how do you like my new jutsu?"

"It's not just good! It's perfect!"

"Koshino, quickly, come back to the clan with me. I need to report your invention to the elders! Hurry!"

Wow!

The conversation between Koshino and Shikaku naturally echoed through Hizashi's estate.

And upon learning that Koshino, at just four years old, could modify the Nara Clan's secret techniques and develop new ones, Hizashi, Choza, Inoichi, and the others felt as if they were living in a dream!

Since when could a four-year-old improve clan techniques and invent new jutsu?

Even in the original story, Kakashi Hatake, a renowned genius, invented his first jutsu at the age of twelve!

Now, Nara Koshino, at just four, could develop new techniques, slightly putting the Nara Clan head out of composure. The other clan leaders, witnessing this, saw it as a monstrous display of talent!

The Nara Clan was about to rise!

In an instant, this thought emerged in the minds of almost all the clan leaders!

Meanwhile, Koshino, hearing Shikaku's words, maintained his faint smile. Then, he turned to face Fugaku Uchiha, smiling even more broadly, and asked, "Lord Fugaku, should we settle our bet now?"

"Hmph!"

With a cold snort, the better Koshino performed, the more talented he appeared, and the angrier Fugaku grew.

However, Koshino's ability to develop new techniques at just four years old did change Fugaku's perspective.

Before realizing Koshino's inventiveness, Fugaku harbored resentment for the boy embarrassing him. But upon discovering Koshino's talent, Fugaku felt more disappointment in his clan members, who failed to defeat Koshino and couldn't even match his talent.

Nevertheless, for the sake of the clan's honor, Fugaku had to fulfill the wager.

Taking a scroll from one of his clan members, Fugaku tossed it to Koshino, forcing a smile as he said, "Koshino, this scroll contains a Uchiha Clan technique for shuriken training. It's yours. I hope our clan's technique shines in your hands and doesn't bring shame to the Uchiha name."

"Don't worry, Lord Fugaku. I won't disappoint you!"

With the Shadow Shuriken now developed, Koshino had been fretting over his lack of shuriken training to exploit its potential fully. Fugaku's scroll addressed this problem, bringing Koshino much joy. He then prepared to return to the clan with Shikaku to present the new technique and earn some rewards before diligently training the Uchiha Clan's secret techniques.

However, as Koshino approached Shikaku, ready to bid farewell to Hizashi and return to the clan for discussions, another figure emerged from the Uchiha group, catching Koshino's attention!

The more he looked at this person, the more familiar he seemed.

Then, as the boy spoke, Koshino, in shock, guessed his identity!

"Itachi?"

"Is that Uchiha Itachi?"

Yes!

Recognizing the boy's familiar face, Koshino quickly realized that the boy beside Fugaku Uchiha was indeed Itachi Uchiha, the legendary "Itachi"!

Curiously examining the young Itachi, I noticed that his youthful appearance belied his deep, mature gaze.

Itachi, having just emerged from the Uchiha crowd, first looked at Koshino before speaking to his father, Fugaku Uchiha: "Father, Koshino-senpai is very skilled. May I request his guidance? Would that be alright?"

"Oh? Itachi, you want to spar with Koshino?"

Hearing Itachi's request, Fugaku Uchiha frowned.

I had already lost the Uchiha Clan in the contest against the Nara Clan. If Itachi were to lose again, what would happen to the Uchiha Clan's honor?

So, with a furrowed brow, Fugaku's first instinct was to refuse Itachi's request for the sake of the clan's dignity.

But before Fugaku could decline, Koshino, staring at Itachi's youthful face, felt a fierce battle spirit ignite in his eyes for the first time. He then smiled at Itachi and said:

"Itachi Uchiha, is it? I've heard of your reputation!"

"I've long wanted to spar with you. May I have a moment to recover my chakra?"
