Shun!
Its inventor was none other than Yoruichi Shihōin, famed as the "Goddess of Flash. "
It was a combat art that merged Kido and Hakuda—a fusion so potent it was regarded as a forbidden technique.
When one used this move, the practitioner's back and shoulders would be wrapped in highly compressed Kido energy. Then, by channeling that spiritual power through one's own limbs, body and energy became one in perfect harmony.
It was, in essence, the pinnacle of Hakuda enhanced by an unceasing surge of destructive Kido. Together, they created what was known as—
Shun!
Every motion, every gesture, carried devastating power.
And at this moment— Through your mastery of both Kido and Hakuda, you have attained enlightenment!
You have created Shun!
Shun: A forbidden-level combat art that fuses Hakuda and Kido!
Instantly, Naruto's mind flooded with a torrent of knowledge, insights, and instinctive muscle memory regarding Shun.
Without hesitation, he entered his sealed inner space. There—away from prying eyes and interference—Naruto performed Shun for the very first time.
In that instant, a vast surge of chakra erupted from his body, wrapping around his shoulders, his back— then coiling down his arms and legs.
"BOOM! !! "
Thunderous detonations echoed as Naruto lowered his gaze to observe his new Shun form. He could feel his body brimming with boundless power.
Then— He dashed forward.
In that single movement, Naruto's speed spiked so sharply that the air cracked into a sonic boom. The shockwave shook the entire sealed space, making the Nine-Tails in his cage flinch.
The beast looked up, startled— but Naruto's form had vanished.
All he could see was a blinding white flash darting across the seal like lightning incarnate.
"That's… Naruto? "
The Nine-Tails' eyes widened in disbelief.
This brat's speed— It far surpassed any form he'd ever used before.
What power has this kid discovered this time? The Nine-Tails' mind trembled.
But this—this was only the beginning.
When Naruto finished savoring the intoxicating speed of his newly forged Shun, he didn't stop there. He knew this was just the starting point.
Masters like Yoruichi Shihōin and Soi Fon possessed evolved forms of Shun.
Naturally, Naruto intended to push his to the limit.
So— With his profound understanding of Shun, and inspired by the techniques of Yoruichi, Soi Fon, and Yūshirō Shihōin— He attained enlightenment once more!
You have created: Infinite Shun, Thunder God Battle Form, Thunder Beast Battle Form: Nine-Tailed Fox Mode, and Explosive Flame Unrivaled!
Infinite Shun: Fierce wind pressure wraps around the body—an ultimate fusion of Hakuda and Kido, producing near-infinite destructive power in every motion!
Thunder God Battle Form: Transform into the deity of lightning; six thunderous magatama manifest behind your back!
Thunder Beast Battle Form: Nine-Tailed Fox Mode: Manifest the power of lightning into the form of a nine-tailed fox!
Explosive Flame Unrivaled: Every strike unleashes flames capable of annihilating all creation!
At once, a cascade of advanced Shun forms flooded Naruto's mind.
Hovering midair, surrounded by an aura of roaring energy, he roared—
"Thunder Beast Battle Form: Nine-Tailed Fox Mode! !! "
A crackling sound split the air as torrents of lightning burst from his body. Massive chakra surged outward, taking shape—
In an instant, an enormous, lightning-forged nine-tailed fox formed around Naruto. Nine immense thunder-whips lashed through the air, each crack like the roar of a storm.
The dazzling brilliance of the lightning illuminated the once-dim seal space, revealing the Nine-Tails' true form behind the crimson bars.
The beast's eyes widened in horror, staring at the human standing at the fox's brow.
He couldn't believe it.
That brat— He had used lightning chakra to create a monster that mirrored him!
"You little brat! !! "
The Nine-Tails' voice quaked with a mix of anger and unease.
Because he could feel it— Naruto's thunder-fox form carried chakra equal to that of a true tailed beast.
In other words— Naruto had just created a real tailed beast.
Its size, its chakra—it was the same level as a bijuu. And unlike the others, it wielded the most destructive element of all— Lightning!
Every motion of that creature was enough to shake the world.
Even the Nine-Tails had to admit—this wasn't an insult to other tailed beasts, but the truth was that this newborn creature wasn't anyone else— It was Naruto.
Even as one sharing a body with him, the Nine-Tails couldn't begin to fathom what kind of monstrous potential still slumbered within this kid.
Then, from the fox's brow, Naruto looked down at him— a confident smile on his face.
"Yo, Kurama—so this is how you usually see people, huh? "
The Nine-Tails froze.
What the hell? !
This brat had just created a forbidden jutsu beyond S-rank, and that was his first thought? !
He suddenly felt like coughing up blood. This kid treated world-shattering ninjutsu like it was pocket change.
But then again— thinking back over everything Naruto had achieved, perhaps that was simply who he was.
Where others celebrated creating a single useful jutsu, Naruto created them as effortlessly as breathing.
Even the First Hokage— that godlike man who once dominated the ninja world— seemed almost ordinary compared to this monster. That guy only had Wood Release.
But Naruto?
You can't even compare!
The Nine-Tails couldn't help but silently mourn for Naruto's future enemies— especially those disgusting old men sitting in Konoha's council, like that decrepit Third Hokage, Hiruzen Sarutobi.
He wondered— would that old fool ever regret what he'd done to Naruto?
But that was a concern for another time.
For now, Naruto continued testing the rest of his Shun evolutions— Thunder God Battle Form, Infinite Shun, and Explosive Flame Unrivaled.
Each transformation left the Nine-Tails in the cage trembling, heart pounding with dread.
He had gotten used to Naruto creating new jutsu every other day— but seeing it firsthand was a different story altogether.
It was pure, terrifying brilliance.
