One Piece: SSS-Rank Haki at Age Seventeen

BOOM—!!!

Two overwhelming auras exploded into the sky, their collision releasing shockwaves like tidal waves that crushed the heavens themselves. Even distant clouds were shattered by the impact.

"You've improved a lot, Yamato!!"

Amid the raging air currents, Luffy grinned broadly. His skin instantly turned jet black—the deepest form of Armament Haki, condensed to an abyss-like density.

His fist pressed against a kanabo wrapped in Conqueror's Haki Infusion.

Purple-black lightning crackled around the iron spikes like living creatures, each flash making the air wail.

Opposite him stood a young woman with silver-white hair whipping wildly in the shockwaves.

It was Yamato.

Her white kimono fluttered violently as she gripped the kanabo with both hands.

"You're incredible, Luffy!!"

Battle spirit burned in Yamato's eyes—hotter than the fiercest flames of Onigashima.

"If I can keep up with you… if I can reach the level you're at now… then I'll definitely be able to knock Kaido flying and open Wano's borders, right?!"

"Uh… well, maybe—"

The grin on Luffy's face suddenly turned fierce.

His foot slammed into the ground, shattering the earth as the turf rolled upward like waves.

An even deeper black spread across his fist—not ordinary Armament Haki, but a flowing, devouring force.

Ryuo.

"But right now—"

His punch looked slow, yet dozens of afterimages trailed behind it.

"—you're still nowhere near strong enough!!"

BOOOOM—!!!

Compressed air exploded inward from every direction with a world-shattering roar.

Yamato shot backward like a meteor. Gritting her teeth, she stabbed her kanabo into the ground, tearing through rock as if it were tofu.

A terrifying trench nearly one kilometer long ripped across the earth behind her, soil and grass spiraling into a massive cloud of dust.

Finally, her body stopped at the far end of the trench.

A thin line of blood seeped from the corner of her lips, staining the snow-white collar of her kimono like a crimson plum blossom.

Yet her gaze burned hotter than ever—like magma beneath a frozen volcano—locked firmly on the calm young man across from her.

Yamato inhaled deeply, as if drawing in twenty years of vows and strength at once.

"Luffy—actually… I'm also a Devil Fruit user!!!"

CRACK—CRACK—!!!

Pale ice flames suddenly erupted beneath her feet, spiraling upward like a waterfall flowing in reverse.

Where the flames passed, grass and shrubs instantly froze into crystalline sculptures.

Frost spread rapidly across the ground.

At the same time—

An even more violent burst of Conqueror's Haki exploded outward.

Purple-black lightning surged from every pore of her body, intertwining wildly with the pale ice flames.

The girl standing there transformed completely.

A massive, fluffy wolf tail extended from her spine.

Her limbs became longer and more powerful, covered in frost-like fur.

Wolf ears rose atop her head.

Each breath she exhaled froze into drifting crystals.

Azure cloud-like markings glowed faintly beneath her skin.

Behind her, the phantom of a divine wolf appeared—

A being combining thunder's ferocity with sacred frost.

The pressure of the Mythical Zoan known as the Okuchi no Makami descended upon the battlefield like the crushing air before a blizzard.

"Ho… a Mythical Zoan?"

From afar, under the shade of a tree, Silvers Rayleigh, the Dark King, paused mid-sip from his sake bottle.

A sharp glint flashed in his eyes.

With his experience, he knew exactly what that meant.

Among all Devil Fruits, Zoans were the most common.

But the ones standing at the very top of the pyramid—

The chosen among them—

Were the Mythical Zoans.

Rayleigh took another drink, his gaze drifting as if through time.

He seemed to see a certain dragon coiled above Onigashima.

"Is this simply fate's strange luck…?"

"Or did Kaido pour unimaginable effort into creating this 'masterpiece'?"

Battlefield Center

Luffy's expression remained calm.

A strange red glow covered his eyes.

Everything in the world seemed to move in slow, clear trajectories within his vision.

That was Observation Haki pushed to an extreme.

Meanwhile, powerful flowing Armament Haki moved beneath his skin like a living force.

"Come!!!"

Without another word, Luffy vanished from where he stood.

He became a streak of black cutting through space itself, charging straight toward the storm of ice and lightning.

Yamato's pupils shrank.

She clenched her teeth, gripping the kanabo tightly.

Ice flames burned beneath her feet, her wolf tail stretched taut behind her as she gathered the full power of her Mythical Zoan.

The next instant—

BOOOOOM!!!!

The collision of kanabo and Haki-coated fist became the island's new heartbeat.

The entire island trembled violently.

Shockwaves spread outward in rings.

Forests were flattened.

Gigantic waves rose along the coastline.

The domain of frost and lightning clashed against the unstoppable black spear of Luffy's will.

Above the island, a battle that could shape the future unfolded.

Elsewhere on the Island

"Hmm…"

Rayleigh clicked his tongue softly as he shifted his gaze from the ice-and-lightning battlefield to the other side of the island.

"Those two kids…"

Compared to Luffy and Yamato's island-shaking monster battle, the fight here seemed… almost modest.

Trafalgar Law and Sanji clashed rapidly among the trees.

"ROOM!"

Law expanded his spherical domain again, the blue space engulfing several giant trees.

With a twist of Kikoku, he swapped a tree trunk with the stone beneath Sanji's foot.

But Sanji had already become a streak of blue flames, appearing beside him with a blazing spinning kick.

"Too slow, Tra-guy!"

Law barely raised his sword to block.

CLANG!

The impact sent him sliding several meters back, heat spreading across the blade.

The flow of the battle was obvious.

Sanji still held an overwhelming advantage.

His speed, strength, and genetically enhanced recovery created a massive gap.

Most of Law's attacks were predicted and evaded before they could land.

But Rayleigh's experienced eyes saw far deeper.

Every one of Sanji's attacks seemed to crash against an invisible wall that was gradually thickening.

Sanji had reached a bottleneck.

It wasn't a lack of power.

His famed Observation Haki and combat skill had already reached the peak of his current state.

Meanwhile—

Law was in what Rayleigh considered the healthiest stage of growth.

Under extreme combat pressure, his Devil Fruit mastery, Haki control, and combat instincts were being pushed to their absolute limits.

Rayleigh took another sip of sake.

In truth, the difference in their talent wasn't insurmountable.

Sanji's bottleneck came from standing on a higher platform—he needed a moment of enlightenment to break through.

Law, meanwhile, was sprinting forward, widening the path beneath his feet.

Their battle had long surpassed simple victory or defeat.

It had become the violent collision of two different growth trajectories.

One was knocking on the ceiling of his limits.

The other was racing upward to reach that ceiling.

At the Same Time…

Beep. Beep. Beep.

A short, crisp sound suddenly came from beside Rayleigh.

A special Den Den Mushi resting on a wooden post began flashing red from the tips of its antennae.

"Oh?"

Rayleigh's eyes lit up instantly.

"So it's finally starting at this time?"

Without hesitation, he completely turned his attention away from the massive battles across the island.

Right now, nothing in the world seemed more important than that tiny Den Den Mushi.

It was a Special Broadcast Den Den Mushi.

An accidental creation by Dr. Vegapunk during one of his idle experiments.

Unlike the broadcast snails used during the Marineford War, which could only transmit images one way, this version had a breakthrough feature—

Scrolling text interaction.

Viewers could send and receive messages.

That small innovation had changed communication and entertainment across the seas.

All over the world, new "streamers" began appearing:

Traveling bards.

Chefs.

Fighters.

Even ordinary people sharing their lives.

The live broadcast Den Den Mushi quickly became popular throughout the Grand Line and even the Four Seas.

While recovering from his injuries, Rayleigh had asked Shakky to get him one at all costs.

He still remembered the knowing, teasing smile she gave him.

And so—

The legendary "Right Hand of the Pirate King" ended up becoming unexpectedly addicted to this new gadget.

Using the instincts honed by decades of Observation Haki—which he insisted was simply intuition—

Rayleigh navigated the vast "sea of broadcasts."

And somehow… he always ended up watching the channels of young female streamers full of energy and talent.

According to him, he was simply:

"Appreciating the vitality and beauty of the new era."

After extensive "research" and "aesthetic refinement," Rayleigh eventually settled on a particular rising singer.

Her voice lacked flashy technical tricks.

Instead, it carried a pure power that seemed to pierce through dust and reach the soul.

Her smile held both youthful sweetness—

And a faint trace of loneliness and determination.

Now, the Den Den Mushi's shell began glowing steadily.

A small projection screen displayed the pre-stream announcement.

Rayleigh quietly waited, focused like a guardian about to witness an important moment.

The thunderous training battles across the island faded into mere background noise.

This rising idol—

Praised by countless fans as a "Heavenly Voice from the Other Shore"—

Was named—

UTA!!!!
