Naruto: Sukuna's Jinchuriki, I am Uchiha

Chapter 4: Someday, I Will Break the Seal…

Serpent-Ram-Monkey-Boar-Horse-Tiger.

That was…

After a brief clash, Uchiha Kagami quickly weaved hand signs, shocking the teacher into shouting.

"All students! Scatter!"

Kakashi's pupils shrank as he reacted swiftly.

"Fire Release: Great Fireball Technique!"

"Earth Release: Earth-Style Wall!"

The Great Fireball Technique, a signature jutsu of the Uchiha clan, was widely known throughout the ninja world.

Almost every Uchiha learned this technique as their first jutsu.

Having heard from Obito that Kagami knew Fire Release, Kakashi assumed he could use the Great Fireball Technique. So, as soon as Kagami started weaving signs, Kakashi was ready.

Boom!

The raging fireball shattered the earth wall!

Kakashi had made the correct counter, but he had underestimated the power of Kagami's jutsu.

"Damn it!"

The chunin teacher felt things going wrong and moved instantly to rescue Kakashi.

Poof!

Just before the flames reached him, Kakashi's body exploded into a puff of smoke, leaving only a broken piece of wood.

A substitution jutsu!

When did he…?

---

Poof!

Kagami spun around and ducked, meeting Kakashi's punch from behind as he emerged from the ground.

The intense taijutsu battle resumed.

---

"This… this is a real ninja fight!" whispered Obito, forgotten in the corner, his eyes full of disbelief.

And a little bit of frustration.

The Uchiha clan revered strength, and he frequently heard his clan members praising Kagami. But when their eyes fell on him…

Rin Nohara, noticing, gently patted Obito's shoulder and smiled, "You're amazing too, Obito. I believe you'll become a great ninja someday!"

"Mhm!"

The shadows clouding Obito's heart vanished with Rin's smile.

Madara was truly perceptive. Had Rin lived, Obito would never have unlocked the Mangekyou.

You should be thankful to Lord Madara for his gift, Obito!

---

"Earth Release: Earth Wave!"

Among his peers, Kakashi's chakra reserves were exceptional.

The Earth Wave, a lesser earth-style jutsu, sent waves through the ground, disrupting Kagami's movement.

"Among those under ten I've faced, Kakashi, you're the strongest."

Kagami leaped over the waves, a faint smile on his face throughout.

"But I'm tired of this game."

"Your essence… is lacking."

As soon as he spoke, a scarlet light reflected in Kakashi's eyes.

An image of a monstrous god of blood crashed into his mind, freezing his body and spirit.

Sharingan Genjutsu: Special Edition by Sukuna.

Kagami's double-tomoe Sharingan spun as he approached Kakashi, resting his hand on the hilt of Shirayuki.

A hand landed on his shoulder; the teacher's voice was slightly trembling, "Enough… You've won, Kagami."

Looking down, the teacher saw Kagami's scarlet eyes and swallowed nervously.

He had heard of a five-year-old prodigy in the Uchiha clan… but to awaken double tomoe so soon?

Whether he had awakened at an earlier age or evolved to double tomoe at five… both were terrifying.

The arena fell silent.

Everyone watching Kagami's fight with Kakashi hadn't expected Kagami to win, but…

They couldn't understand how Kagami had won at all!

Until Kagami's gaze swept over them, the scarlet glow falling upon their eyes.

Even as kids, they knew what this meant.

One of the Three Great Dojutsu, the ultimate symbol of the Uchiha…

The Sharingan!

Kagami was pleased with their reverent expressions.

This is right. The Uchiha don't need bonds. You only need to bow down and admire me.

Even without the Sharingan, he was confident he could have beaten Kakashi.

But why hide it?

A person's character is influenced by their environment, education, and another crucial aspect… their body.

Poor lungs lead to sadness.

A troubled liver leads to anger.

A weak stomach leads to resentment.

With the Uchiha's keen intellect, it's only natural to be arrogant!

Acting meek in silence? That would make him another Fugaku.

Kagami's character was shaped by the Uchiha genetic influence, but mostly by his own attitude.

In his past life, he had no family or friends. If he had been born in ancient times, he would have been treated as an unstable element, trained as an assassin.

But here…

The sky is the limit when the ocean ends.

---

His eyes lost their scarlet hue as Kagami spoke indifferently, "My name is Uchiha Kagami. I don't like arrogant challenges, being disturbed while I eat, or Obito Uchiha."

Obito Uchiha: "…"

---

In the Hokage's office, the smoke was thick beyond belief.

Watching the scene in his crystal ball, Hiruzen Sarutobi frowned deeply.

This child… needed proper guidance.

He summoned his secretary and spoke solemnly, "Jiraiya's training Minato lately, right?"

"Yes, Hokage-sama. They're currently in the Forest of Death for training."

Hiruzen pondered for a moment, ultimately deciding not to act too soon.

For now, let the child stay in the academy. Maybe interaction with his peers would soften his personality.

If that didn't work, perhaps Minato, the "Little Sun," could shine on this Uchiha boy.

In Minato, Hiruzen saw a radiance that could unite everyone, brighter than his ninjutsu talent.

---

If not for his performance in the training ground, Kagami would seem far more well-behaved than Obito.

He never disrupted class or fell asleep.

Though he also ignored the teacher whenever asked a question.

Kagami had already mastered the ninja academy curriculum. Walking on water and trees were child's play, and he had nearly completed his clan's chakra nature transformation lessons.

The ultimate form of chakra nature transformation was the Rasengan. He wondered if Minato had developed it yet.

This was also Kagami's current goal, and he had the full lesson plan and a standard solution to work from.

If he could master it before Minato, then the Uchiha would be the rightful creators of the Rasengan.

Minato Namikaze?

If you weren't Jiraiya's student, I'd accuse you of plagiarism!

Of course, everything depended on Kagami creating the Rasengan first.

Sitting quietly, Kagami let his consciousness dive into his spiritual space.

Before a massive gate, Kagami sat down and began his training.

The Rasengan had three stages: "Rotation," "Power," and "Sustain."

Kagami was stuck at the third stage.

The Rasengan was like a miniature typhoon focused in his palm, with sustaining it being the hardest part.

"Kid… what's happening out there… And what's up with those eyes of yours…"

Kagami had infused his Sharingan Genjutsu with Sukuna's cursed energy as an experiment.

It had worked well; if not for the head teacher's intervention, Kakashi would have been stuck there till morning.

It also allowed Sukuna to sense a bit of the outside world.

Chakra was a perfect fusion of mental and physical energy, while cursed energy originated from negative emotions, only one type of mental energy.

To Sukuna, all of those kids outside had cursed energy!

He even sensed a few strong cursed energies nearby, equivalent to top-class sorcerers.

This density of powerful individuals was highly abnormal…

Most importantly… it was the first time he had directly sensed Kagami's eyes.

Though they didn't seem harmful to him now…

It was like comparing himself, a wild bull, to Kagami's Sharingan, which was more like a lion… or rather, a dragon egg.

He had an inkling that if these eyes "hatched," they could shatter his immortal body effortlessly!

In a spare moment, Kagami glanced at him, saying, "That's why it's so annoying."

"Other people get powers instantly or have systems that give them quests, and here I am with someone like you, stuck halfway."

---

"Kid! What did you just say?!"

"Calm down, Sukuna."

"This world is far more dangerous than you realize. Beings that can kill you are everywhere, so lose that needless recklessness."

"Listen to me obediently, and you might even get the chance to be summoned as my familiar."

Sukuna seemed to understand "familiar" and sneered, "Before I reach the peak of this world, I care nothing for begging."

"Compared to me, you're the one with no sense of your limits. With your meager power, you dare reveal yourself to others."

"I'm nothing like you."

Kagami smiled slightly as the chakra orb in his hand grew a bit more stable.

"If I die, it means I wasn't worth much to begin with."

"I'll never cower to survive, like you."

Scarlet eyes met the god of death hidden in the darkness.

"I'm fully aware of my insignificance. Does that mean I should hide?"

"To face the impossible, Sukuna, you've lost the most vital instinct of humanity. You're nothing more than a powerful beast."

"So you'll serve as my mount, and I'll be the one to guide you!"

---

"Kid, you're merely a commoner relying on this unknown cage to bind me. Don't talk big."

Kagami leaned closer to the seal, smirking.

"Sukuna, someday, I'll open the Seal"

"I put the leash on you"
