Naruto: Strongest Shinobi System With a Glitch
Chapter 427 - HAHAHAHAH - again!!
Kitazawa glanced at the notification briefly. Then he took a step back, raised a hand, and pressed it firmly against his forehead.
A dark, oppressive surge of chakra erupted within his body.
Unlike Sasuke’s earlier outburst, however, Kitazawa immediately suppressed it, preventing the aura from leaking outward.
Primarily to avoid trouble.
After all, Sasuke was standing right in front of him. If Sasuke noticed something unusual, explaining it would become unnecessarily complicated.
Kitazawa took a slow breath and began examining the information the system had just transmitted into his mind.
Naturally, what interested him most was the Mangekyō Sharingan’s ocular abilities.
After all, the true strength of the Mangekyō Sharingan largely depended on the techniques tied to it.
Take Obito, for example.
Because Kamui was overwhelmingly powerful, Obito’s overall combat ability skyrocketed.
If his battle instincts had been sharper, he might have been nearly invincible.
But as Kitazawa finished reviewing the information, his brow gradually furrowed.
Because—
He hadn’t awakened any ocular techniques at all.
[Host can obtain corresponding Mangekyō Sharingan ocular abilities by completing related system missions.]
[Additionally, the Host can absorb Mangekyō Sharingan ocular abilities from others.]
The text floating before his eyes suddenly changed.
Kitazawa paused, momentarily stunned.
Did that mean...
He could potentially possess multiple Mangekyō abilities?
Before he could think further, another line appeared.
[As fellow students of the Genius Class, you and Uchiha Sasuke must determine whose Mangekyō is the strongest.]
[Current Mission: Defeat Uchiha Sasuke]
[Mission Reward: Uchiha Sasuke’s Mangekyō Sharingan ocular ability]
[Do you accept?]
Kitazawa’s lips twitched.
This ridiculous system still remembered that he was technically a student of the Genius Class?
Still...
There was no reason to refuse this mission.
Even if Sasuke possessed Amaterasu and Blaze Release: Kagutsuchi, Kitazawa wouldn’t lose.
That said, he secretly hoped Sasuke had awakened something else.
Those two abilities were powerful, but their overall versatility wasn’t particularly outstanding.
Suddenly, the text shifted again.
[Detected: Host possesses one Mangekyō Sharingan. If a pair is collected, the ocular ability can be absorbed.]
Kitazawa instinctively narrowed his eyes.
After killing Danzō, he had kept the Mangekyō Sharingan he seized instead of returning it to the Uchiha clan.
Originally, he had planned to let Sasuke absorb Shisui’s Mangekyō Sharingan in the future.
But now...
The system’s words made him reconsider.
Wait.
No.
The plan didn’t actually need to change.
The system only mentioned absorbing the ocular ability.
In theory, the physical pair of Mangekyō Sharingan would still exist afterward.
Which meant—
Kitazawa could absorb the ocular technique, while Sasuke could absorb the ocular power to awaken the Eternal Mangekyō Sharingan.
Both outcomes could coexist.
Kitazawa couldn’t help nodding slightly.
Coincidentally, he had been wondering how to persuade Itachi to hand over the second Mangekyō Sharingan.
Now he had the perfect reason.
If the goal was helping Sasuke awaken the Eternal Mangekyō Sharingan, Itachi would certainly agree to provide Shisui’s remaining eye.
"Sasuke."
Kitazawa snapped back to reality and called out.
Sasuke finally stopped laughing, gradually suppressing his excitement.
The first thing he did was glance at Uzumaki Naruto.
After awakening the Mangekyō Sharingan, his immediate instinct had been simple—
Defeat Naruto and avenge the humiliating beatings he had endured recently.
"Sasuke, you’ve just awakened the Mangekyō Sharingan," Kitazawa said calmly.
"You won’t be able to control it perfectly yet. For now, avoid sparring with your classmates."
"You’ll have plenty of opportunities next semester."
Sasuke hesitated briefly before nodding.
Kitazawa was right.
He hadn’t fully mastered the Mangekyō Sharingan yet.
His strength had increased too abruptly—he needed time to adjust.
More importantly...
He didn’t want to lose to Naruto because of impatience.
Once he fully mastered this power, victory would be inevitable.
"Alright, Naruto. Your combat training ends here for today," Kitazawa said after a moment’s thought.
"Next, you’ll begin chakra control training."
Naruto had already reached the stage of partial Tailed Beast transformation.
The next step was Nine-Tails’ chakra mode.
Moving from controlling a fragment of Kyuubi’s chakra to controlling most of it required far more refined chakra manipulation.
And ordinary combat training wouldn’t improve that.
"You’ll train with my shadow clone."
Kitazawa formed a hand seal.
A Shadow Clone appeared beside him instantly.
"Sasuke!" Naruto said, flashing a thumbs-up.
"Next semester, let’s have a battle full of youthful spirit!"
He was eager to fight Sasuke after his Mangekyō awakening.
But since Kitazawa had spoken, Naruto didn’t insist. Waiting until next semester was fine.
"Hmph. Just make sure you don’t cry when you lose." Sasuke replied confidently.
"Sasuke," Kitazawa said thoughtfully, "let’s spar for a bit. I want to see how strong you are now."
Sasuke hesitated.
"Should I use my Mangekyō Sharingan’s abilities?"
"What?" Kitazawa chuckled. "Do you think I’d lose to you?"
Sasuke quickly shook his head.
Even though—Deep down—He actually did.
The Mangekyō Sharingan had boosted his confidence tremendously.
"Then come."
Kitazawa stepped back a few paces, widening the distance between them.
Regardless of the system mission, this fight needed to happen.
Sasuke’s current arrogance had reached dangerous levels.
Such a mindset wasn’t conducive to growth.
Though admittedly...
It suited Sasuke’s personality perfectly.
In the original timeline, Sasuke had been even more reckless.
After awakening the Mangekyō Sharingan, he had charged straight into the Five Kage Summit.
If not for Obito’s intervention, he might have become the fastest Mangekyō user in history to die.
The battle began.
Sasuke immediately activated his Mangekyō Sharingan.
"Mangekyō Sharingan: Genjutsu!"
His pupils burned with power as terrifying ocular chakra surged outward.
Kitazawa instantly felt a cold, oppressive sensation brush past his mind.
But he possessed Mangekyō-level Genjutsu resistance.
The illusion had no effect.
"...?"
Sasuke stared at him in confusion.
What was going on?
His genjutsu should now rival Yakumo’s level.
Why didn’t it work?
He didn’t have time to figure it out.
Because Kitazawa had already moved.
Konoha-Style Kenjutsu.
Activating his Byakugan, lightning chakra crackled across Kitazawa’s blade as he dashed forward at blinding speed.
Sasuke’s pupils shrank.
Even with the Mangekyō Sharingan’s enhanced dynamic vision—
He could only barely track a blur.
Instinctively, Sasuke drew his Thunder God Sword and raised it defensively.
Clang!
A massive force slammed into him.
Sasuke was immediately pushed backward, unable to resist.
Kitazawa followed relentlessly, closing the gap again.
He used no ninjutsu—Only pure Konoha-style swordsmanship.
Hatake-Style Kenjutsu!
Sasuke counterattacked quickly.
But Kitazawa sidestepped effortlessly.
Another strike descended.
Clang!
Sasuke was forced further back.
Metal clashed repeatedly, the sharp sounds echoing through the forest.
Within just five seconds, Sasuke had already been driven back more than ten meters.
"Yang Release: Chakra Mode!"
Kitazawa raised one hand.
In an instant, the entire forest seemed to come alive.
Trees trembled, roots twisted, and vines surged wildly across the ground. The forest itself responded to his chakra.
Sasuke tried to retreat, but it was too late.
Thick vines and branches shot forward like living chains, wrapping tightly around his limbs and torso, pinning him in place.
Just as Sasuke prepared to activate his Mangekyō Sharingan again—
Kitazawa casually crooked a finger.
A thick tree trunk swung down and tapped Sasuke on the head.
The blow wasn’t heavy, but it was enough to leave him dizzy.
"Alright," Kitazawa said calmly.
"This sparring match ends here."
He walked forward and placed both hands on Sasuke, channeling healing chakra to restore him.
When Sasuke finally regained his senses, his expression was blank—almost as if he were questioning reality itself.
How... had he lost so completely?
He had awakened the Mangekyō Sharingan.
Fugaku had once told him that anyone who awakened the Mangekyō would become one of the top powerhouses in the shinobi world.
In the past, Uchiha Madara had been able to stand toe-to-toe with Senju Hashirama precisely because of this power.
And yet—
The reality before him suggested that something about that story was... deeply misleading.
At that moment, three lines of text appeared before Kitazawa.
[Current Mission: Defeat Uchiha Sasuke]
[Mission Reward: Uchiha Sasuke’s Mangekyō Sharingan Ocular Ninjutsu]
[Mission Completed. Reward Issued]
Kitazawa’s eyes flickered with anticipation.
Soon, a flood of information poured into his mind.
He quickly grasped the full effects of Sasuke’s two Mangekyō abilities.
The ocular technique of the left eye was called Amenotejikara.
Its ability allowed the user to designate a target and leave behind an ocular mark, then instantly teleport through space to the target’s location.
In principle, it resembled the Flying Thunder God Technique, though there were several differences.
First, it couldn’t transport other people or objects.
However, it possessed one major advantage over Flying Thunder God—
The mark could be placed instantly with a single glance.
There was, however, a limitation.
Only five ocular marks could exist simultaneously.
Second, these marks were detectable.
But detecting them required a higher level of Yin Release than Sasuke possessed.
Even then, removing the mark took time.
Kitazawa tested it briefly.
With his current strength, erasing the mark required roughly half a second.
For someone like Itachi or Obito, it would probably take one to two seconds.
Finally, teleportation range was limited to the user’s line of sight.
It could not be activated outside the field of vision.
In short—
Amenotejikara functioned like a simplified version of Flying Thunder God.
But that didn’t make it weak.
On the contrary, it was an extremely abnormal ability.
For most shinobi in the world, it would be nearly impossible to counter.
The ocular technique of the right eye was called Amanoiwato.
Its effect was simple, yet terrifying.
For one hour, it could greatly amplify the user’s chakra reserves.
The multiplier depended on the user’s ocular power, with a maximum increase of ten times.
With Sasuke’s current Mangekyō strength, the boost was roughly double.
When Kitazawa saw this ability, he almost felt as if he had struck gold.
Because it suited him perfectly.
A tenfold increase in chakra would make him arguably the shinobi with the greatest chakra reserves in the entire world.
Although the effect lasted only an hour, that was more than enough.
If he eventually mastered Sage Art: Wood Release – True Several Thousand Hands, one hour would be plenty of time to sweep through the entire shinobi world.
Of course, if the technique was maintained beyond that hour, it would begin burning the user’s lifespan.
Kitazawa stroked his chin thoughtfully.
In his opinion, these abilities—Amenotejikara and Amanoiwato—were far more useful than the traditional pairing of Amaterasu and Blaze Release: Kagutsuchi.
At the very least, by next semester, Sasuke would finally have a real chance of defeating Naruto.
After all, Naruto’s Yin Release perception wasn’t strong enough to detect the Amaterasu mark.
And with Amanoiwato doubling Sasuke’s chakra for an entire hour, overwhelming Naruto would no longer be a distant dream.
"Sasuke," Kitazawa said with a smile as he dispelled Wood Release constructs, "for the time being, you don’t need to come to the Ninja Academy."
"Just stay home and familiarize yourself with the Mangekyō Sharingan."
"...Yes, Kitazawa-sensei."
Sasuke nodded, though his voice sounded slightly dejected.
After all, he had just been defeated rather thoroughly.
"Come on," Kitazawa said. "I’ll walk you back."
He could also use this opportunity to speak with Itachi about Shisui’s Mangekyō Sharingan.
"Mm."
Sasuke nodded.
The two of them began walking toward the Uchiha Clan compound.
"Dad! Brother!"
As soon as they reached the house, Sasuke rushed into the courtyard, unable to contain his excitement.
"Why are you running around like that?"
Fugaku stepped outside. When he noticed Kitazawa behind him, he immediately scolded Sasuke.
"Dad!"
Sasuke lifted his head proudly.
"I’ve awakened the Mangekyō Sharingan!"
"...What did you say?"
Fugaku’s eyes widened in disbelief.
An eleven-year-old Mangekyō user?
That was something he had never even dared to imagine.
"Look!"
Sasuke immediately activated his Mangekyō Sharingan.
The moment Fugaku felt the terrifying ocular pressure, all doubt vanished.
He stood frozen for two seconds.
Then—
He burst into uncontrollable laughter.
"HAHAHAHA!"
"As expected of my son!"
Fugaku laughed loudly, completely losing his usual composure.
