Breath of the Sun!
Naruto pictured a blazing sun hanging high in the sky—radiant, eternal, and brimming with boundless energy. That searing power seemed to spill over, flooding the earth below with warmth and force.
In that instant—
By visualizing the sun's immense might and combining it with his understanding of the five basic breathing techniques, Naruto had a sudden epiphany!
He had created a new Breathing Style:
Sun Breathing — the most powerful and primal form of breathing, capable of unleashing overwhelming force akin to the sun itself!
Naruto's lips parted slightly—he inhaled deeply.
BOOM!
His chakra erupted like an inferno, instantly infused with the energy of Sun Breathing. A golden aura blazed to life around him, wild and majestic.
His golden hair billowed in the storm of power, and his sky-blue eyes sharpened like twin blades, their glare too fierce to meet.
Hiss—
Naruto drew another deep breath.
The sudden influx of oxygen surged through his body, making his heart pound like a war drum. It was as if every cell in him had been reborn.
And then—
Feeling the most intense, resolute, and masculine power coursing through him, Naruto formed the Wind Style: Rasenshuriken!
The jutsu screamed to life, spinning with terrifying velocity.
From the center of his palm, the spiraling shuriken gave off sharp, piercing explosions of wind chakra. Under the wide-eyed gaze of the Nine-Tails, Naruto poured the overwhelming force of Sun Breathing into the Rasenshuriken.
BOOM! BOOM! BOOM!
The clash of elemental chakra filled the air, spiraling out into a miniature sun.
"Sun Breathing!"
"Fire Release: Solar Art!"
"Sun Rasenshuriken!!!"
At that moment, Naruto held what felt like the sun itself in his hand—a sphere of searing light and heat that could illuminate the world.
Even the dank, sealed space of the sewer-like mindscape began to glow with warmth.
Inside his cage, the Nine-Tails stared in awe at the boy bathed in sunlight.
It was like watching the birth of a new world.
"You… actually tapped into the power of the sun?"
"Naruto…"
Kurama's voice trembled. What Naruto had accomplished sent shockwaves through the ancient beast's heart.
But Naruto wasn't finished.
Still holding the Sun Rasenshuriken in one hand, he began analyzing, pushing further—
He drew on his knowledge of Sun Breathing… and then turned his thoughts to the moon.
Another epiphany struck.
You have created: Moon Breathing!
Moon Breathing — a style born from calm contemplation and Yin energy, visualized through the serene light of the moon.
Without hesitation, Naruto inhaled deeply again.
He now activated the five foundational breathing techniques alongside both Sun and Moon Breathing in tandem.
The moon, the natural counterbalance to the sun, shone with cold elegance. Its power was soft yet impossibly sharp, as if each breath cut through the very air like a blade.
And then—he created another Rasenshuriken in his left hand.
This time, infused with the refined edge of Moon Breathing.
Yes.
Moon Breathing was keen, delicate, precise—like a crescent moon's arc.
The Rasenshuriken's shape shifted, its blades narrowing and elongating, twisting like slivers of moonlight overlapping and spiraling together.
"Moon Breathing!"
"Wind Release: Lunar Art!"
"Moon Rasenshuriken!!!"
Now, in his left hand, Naruto held the Moon Rasenshuriken, elegant and icy-sharp.
In his right—still blazing with heat—was the Sun Rasenshuriken.
Two forces—one Yin, one Yang.
One radiant and overwhelming.
The other silent and piercing.
As he gazed down at the twin Rasenshuriken spinning in his palms, a sudden inspiration struck him.
If he had come this far…
Then why not combine them?
And so, under Kurama's stunned gaze—
Naruto slowly brought the two swirling spheres of chakra together.
BOOM! BOOM! BOOM!!!
The clash of forces was immediate.
A thunderous roar echoed as the two opposing energies tried to consume each other. The fusion teetered on the edge of catastrophe, threatening to explode with every passing second.
But Naruto endured.
With a will sharpened like a blade and chakra control more precise than ever before, he forced the two Rasenshuriken to merge—
"AAAHHHHHH!!!"
He roared, pressing his palms together inch by inch, pushing past the limits of what should be possible.
At the same time, Naruto continued channeling power through the Full Breathing Method.
In the very next moment—
Sun Rasenshuriken! Moon Rasenshuriken!
The two spiraling forces—one blazing, one serene—finally fused!
The instant of fusion—
BOOM!
A thunderous roar echoed out as a violent storm of chakra erupted, blasting outward from Naruto's position like a divine shockwave.
Inside the cage, Kurama, the Nine-Tails, felt the surging pressure.
Yet his attention wasn't on the storm—
His eyes were locked on the new power forming in Naruto's hands.
In that moment...
The Rasenshuriken in Naruto's grasp had transformed.
It no longer radiated the distinct characteristics of sun or moon—there was neither searing heat nor cool stillness.
Instead, it shimmered with a kaleidoscopic, cosmic glow—as if an entire universe was spinning within its spiraling core.
A vast and boundless starfield seemed to emerge inside the jutsu itself.
Naruto stared in awe, entranced by the fusion he had forged.
Even without touching it, he could feel its grandeur and mystery pressing against his senses.
His eyes remained fixed on the Rasenshuriken—
Its swirling interior looked like it would pull him in, dragging him into the depths of that starry void.
"So this is..."
Naruto's voice was low, filled with reverence and wonder.
"Then I'll call it... the Star Rasenshuriken!"
As soon as he confirmed the name, a brilliant smile lit up his face.
The union of Yin and Yang—Sun and Moon—had birthed a new, transcendent Rasenshuriken.
It was a technique unlike any he had ever created.
In terms of sheer destructive force, it surpassed every jutsu in his arsenal when he was in his base form.
And if he entered Sage Mode—adding the balance of Natural Energy to the mix—
The Star Rasenshuriken's power would increase exponentially.
And that was just the beginning.
He could stack on other chakra enhancements, and the results...
They would be beyond imagination.
At that moment—
Kurama continued watching the spiraling star-shaped jutsu in stunned silence.
The ancient beast had seen countless battles, faced down gods and monsters...
And yet now, staring at the power Naruto wielded in his hand—
He was shaken.
"If that thing hits me head-on…"
Kurama's thoughts trembled.
"The force it carries… could very well obliterate a tailed beast."
A single jutsu capable of killing a Bijuu.
That level of destructive potential...
Even the mighty Nine-Tails couldn't suppress a shiver of fear.
As the strongest of all tailed beasts, Kurama had never imagined the day would come when a mere kid would wield such terrifying might.
But for Naruto—
The creation of the Star Rasenshuriken was nothing short of a miracle.
A perfect culmination of everything he had trained for.
Full Breathing Method—mastery of the seven base styles: Wind, Thunder, Stone, Water, Fire, Sun, and Moon.
Each breathing style infused into his body, amplifying his strength beyond human limits.
And thanks to Naruto's unmatched chakra control,
He could even enter Total Concentration Breathing – Constant—
Maintaining the power of Full Breathing at all times, enhancing his body continuously.
Then, just as Naruto steadied his breath, still basking in the afterglow of his latest technique...
He felt it.
A new power—awakening deep within.
