One Piece: Start with Zanpakutō

"So fast… but that multiplied speed can't be sustained for long. At most, a fleeting instant."

"His Armament Haki is only at the level of Hardening and Imbuement, and his Observation Haki is nothing exceptional either."

"The only thing he can boast about is the More-More Fruit, but that multiplication ability seems to only affect speed and size — not Haki."

Countless thoughts flashed through Rosen's mind like lightning.

After that brief exchange, he had already seen through Brynndi World's overall strength.

In general, his physical skills and Haki were just average. The only thing worth mentioning was the More-More Fruit. But even that, in Brynndi World's hands, wasn't fully developed — it couldn't multiply Haki.

Otherwise.

Even if Brynndi World's Haki was weak, after a hundredfold amplification, he could at least be on par with an Emperor's top commander, if not the Emperor himself.

"World Destroyer…"

"It seems the thing that the Navy and World Government truly feared back then wasn't Brynndi World's strength — it was the More-More Fruit he possessed."

"If used for long-range attacks, multiplying power a hundred times… destroying cities and nations would be no problem."

Rosen instantly understood why Brynndi World carried the title of "World Destroyer."

It wasn't because of his strength — it was simply because the More-More Fruit was too dangerous.

Even underdeveloped, it was already enough to terrify the Navy, the World Government, and any force on the sea.

"I can't let that brat — nor those cherry blossom-like blades — touch me again."

On the other hand,

Brynndi World had also realized how dangerous Rosen was and immediately decided never to allow himself to be caught by Senbonzakura again.

He stomped hard, shaking the broken ice and debris all around into the air. Then, he swept his leg like a dragon's tail.

"Multiplier. Hundredfold Scatter Shot!"

The instant his leg swept out, all the shattered ice and rocks grew a hundred times larger and faster simultaneously.

They became like massive ice and stone cannon shells, tearing through the sound barrier, each powerful enough to penetrate a warship, weaving together into a terrifying web that sealed off all paths of escape, crashing down toward Rosen.

"Going all out, huh?"

Feeling the violent pressure of the wind on his face and hearing the shrill sonic booms ringing in his ears, Rosen's heart tightened slightly.

This was Brynndi World's first time pushing the More-More Fruit's power to its limit — a hundredfold.

Rosen understood.

After tasting defeat in the last clash, Brynndi World had stopped underestimating him and was now unleashing his true strength without any reservation.

"But… you're not the only one who's been holding back."

Facing Brynndi World's full-powered onslaught, Rosen no longer had any reason to test or restrain himself.

He raised his hand, and the countless suspended Senbonzakura blades all roared as if thunder exploded around them.

In the next moment, black and red lightning crackled across every cherry blossom blade.

"Emperor's Manifestation — Myriad Petal Shards."

Rosen lightly swung the hilt in his hand.

Countless blades, each wrapped in violent Haki, pierced the air like thunder falling from the heavens. They carried a heavy pressure that distorted the atmosphere, crashing head-on into the hundredfold scatter shot.

BOOM!

A deafening explosion shook the entire prison floor.

As soon as the cherry blossom blades touched the incoming barrage, they burst forth with terrifying shockwaves of Haki, shredding all those magnified rocks and ice shells into powder in an instant.

But just as Rosen was focusing on controlling Senbonzakura to completely destroy Brynndi World's hundredfold scatter shot, a figure flashed across the prison ceiling like a ghost, leaving behind a series of sharp sonic booms, instantly appearing behind him.

"Multiplier. Hundredfold speed."

Brynndi World's eyes glinted fiercely as he looked at Rosen's exposed back. He clenched his fist, already hardened with Armament Haki, and swung down fiercely.

"Multiplier. Hundredfold punch."

Originally an ordinary hardened jab, after being magnified a hundredfold by the More-More Fruit, its speed tore through the sound barrier, trailing a spiraling airflow like a dragon tearing through the sea.

This terrifying punch could pierce even a giant Sea King with one strike — and it was aimed directly at Rosen's undefended back.

At this moment.

Rosen seemed completely unable to keep up with Brynndi World's hundredfold speed, standing there like a sitting duck.

Or rather.

He was preoccupied controlling Senbonzakura to intercept the scatter shot and had no time to react.

"Paper Art!"

Until the moment Brynndi World's punch was about to land on his back, Rosen's body suddenly began to sway like a willow in the wind, or like a leaf drifting in a storm.

His entire body twisted like dough, slipping along the edge of the fist's wind and letting that hundredfold punch slip past.

"How… how did he dodge that!?"

Seeing his killing blow miss, Brynndi World's face instantly twisted in shock.

A punch he was absolutely confident in — actually evaded!?

It was then that he realized Rosen's Observation Haki was even sharper than his own.

Only by foreseeing and preparing his body in advance could he have avoided such a fatal strike.

If Rosen hadn't read the future with his Observation Haki and preemptively adjusted his movements, he would have been pierced before he could even move.

"Multiplier! Hundredfold speed!!"

Seeing his punch miss, Brynndi World roared in anger.

Yet his body moved with perfect discipline.

Armament Haki spread across his whole body to prevent injuries from sudden stops. Then, he stomped down and once again activated the More-More Fruit to boost his retreat speed by a hundredfold.

But no matter how fast Brynndi World was, Rosen was no slouch either.

That missed hundredfold punch had thrown Brynndi World's balance into chaos. Although he managed to forcibly steady himself and retreat at high speed, this took precious time.

Moreover, he couldn't maintain his top acceleration indefinitely.

"Blut Arterie (Active Blood Dress) — Shave!"

Rosen fully activated his blood-powered suit, not just boosting attack power but also unlocking unimaginable mobility.

In this state, combined with Rokushiki' Shave, his speed easily pierced the sound barrier.

Whoosh!

Brynndi World had just flown back, when Rosen was already right behind him.

His right foot, hardened like a black blade, rose from the ground, sweeping the air upward like a sword drawn from its sheath.

"Infused — Tempest Kick!"

Accompanied by an ear-piercing sonic boom, a slash wrapped in black and red lightning, like a meteor splitting the heavens, tore through the atmosphere in an instant.

Slicing toward Brynndi World with crushing power.

Shhhhk!

At this moment, even though Brynndi World's whole body was covered in hardened Armament Haki, it was like fragile paper before this Conqueror's Haki-infused Tempest Kick.

Boom!

After a brief stalemate, Rosen's Conqueror-infused slash tore through Brynndi World's defense, slicing open the flesh on his chest, and splitting him nearly in two.

A torrent of blood sprayed out like a waterfall as Brynndi World's body was flung backward like a cannonball, carving concentric shockwave rings through the air before finally crashing into the far wall of Infinite Hell.

Even though Impel Down's walls were made of incomparably hard materials, they cracked and caved under the impact.

His limbs and head were firmly embedded in the wall.

From afar, it looked like a giant nail had been driven into the fortress of Infinite Hell.
