One Piece: The user of the Nen-Nen Fruit, who overturned the sea.

"Flame Slash—!"

With a stomp of his foot, the ground cracked, and Kin'emon faced the pillar of fire that descended from the sky.

His body looked as small as a moth in front of the enormous pillar of fire, but his posture of raising his knife showed no hesitation.

The long sword was raised high above his head, and the foxfire on the blade burned to its peak in that instant.

He cleaved down with a single stroke.

Sword energy, carrying foxfire, flew from the blade and struck the center of the pillar of fire with pinpoint accuracy.

Kin'emon swung his sword again, and several more flashes of light appeared, the crisscrossing sword energy cutting the pillar of fire into countless small pieces.

The shards of flame that had been cut apart burned up in mid-air, turning into countless sparks that drifted down.

Kaido's first wave of attacks was completely neutralized.

Kin'emon landed on the ground, his katana pointing diagonally at the ground, the foxfire on the blade still burning.

His breathing was a little rapid, but his square face carried a long-lost sense of joy.

"I am Kin'emon, a retainer of the Kozuki Oden family."

His voice wasn't loud, but every word clearly reached the ears of everyone present.

"Today, we will surely avenge Lord Oden!"

The samurai in the square watched Kin'emon's retreating figure, and saw the foxfire still burning on his sword; their eyes regained their light.

They remembered.

Lord Kin'emon is still alive, Lord Denjiro is still alive, and the legend of the Nine Red Scabbards is not over yet.

Twenty years ago they failed to protect Oden, but twenty years later they still have a chance to atone for their sins.

Hyogoro gripped the hilt of his sword tightly, the veins bulging on his aged arm.

As he watched Kin'emon cleave the heat aura with a single stroke, tears welled up in his cloudy old eyes.

Hyogoro raised his katana high and let out a hoarse battle roar towards the samurai behind him.

"Following the Straw Hat Lord—to defeat Kaido!!!"

Five hundred warriors responded in unison, the sound so powerful that the pebbles on the square seemed to vibrate.

Luffy grinned.

He looked at the azure dragon in the sky, bent over, supported himself with one hand on the ground, and glanced back at his allies behind him.

"Straw Hat Alliance - Onward!"

As soon as he finished speaking, Luffy soared into the sky.

His legs, propelled by the elasticity of the Gum-Gum Fruit, unleashed astonishing speed, transforming him into a thin red streak in mid-air as he hurtled towards Kaido.

Zoro drew all three swords simultaneously, and the jet-black sheen of Armament Haki instantly covered the blades.

Sanji's right foot burst into flames, and the intense heat of the Diable Jambe distorted and blurred the surrounding air.

Kidd's massive metal arm slammed into the ground, using the recoil to propel him into the air, leaving a trail of metal debris drawn up by the magnetic force.

Luo's surgical space expanded to its limit, and a semi-transparent light shield enveloped him and the other supernovas simultaneously. Then, a spatial displacement occurred, and everyone appeared in mid-air at the same time.

Apoo's arms transformed into musical instruments, Hawkins became a giant scarecrow, Becky opened his suit to reveal dozens of cannon barrels, and Drake transformed into an Allosaurus.

The Nine Red Scabbards followed closely behind, each of them stepping on the moon, their katana reflecting nine cold rays of light under the moonlight.

The other members of the Straw Hat Pirates were not to be outdone.

Nami gritted her teeth, her Weather Stick tracing an arc in the air.

Her moonwalk was not yet very skillful, and the sound of her feet stepping on the air was much louder than others, but she still steadily rose into the air.

After two years of training, she was no longer the navigator who could only hide behind others.

With several newly developed pellets attached to his slingshot, Usopp silently chanted "He can't see me" as he performed Moonwalk.

Chopper transformed into his reindeer form, his hooves making a series of crisp sounds as he trod in mid-air.

Brooke's Moonwalk was as elegant as a gentleman's.

Franky was the most outrageous; his mechanical feet were equipped with jet propulsion devices, and with Moonwalk combined with jet propulsion, he charged forward like a cannonball.

Even Bepo and the others from the Heart Pirates followed behind Law using Moonwalk, their postures were crooked, but at least they didn't fall behind.

Roy's decision to publicly reveal the Six Powers of the Navy and the Haki training method was like throwing a fire into a pile of dry wood.

Two years is enough time for these already gifted individuals to undergo a complete transformation.

In the plaza, Hyogoro led his samurai and mink warriors in a continued battle against the remaining forces of the Beast Pirates.

He looked up at the figures rushing towards Kaido in the sky, a smile appearing on his lips.

"Young people—go and make history!"

·······

Luffy took the lead.

His rubber body bounced through the air, each bounce producing a sonic boom.

His figure tore open gaps in the clouds, and moonlight streamed through them, leaving dappled shadows in the night sky.

In just a few breaths, Luffy had already rushed to the top of Kaido's dragon head.

Immediately afterwards, Luffy's body began to swell, his thin body expanding several times its original size.

The jet-black sheen of Armament Haki covered the entire area from his fist to his shoulder.

The muscle lines were clearly visible beneath the black, hardened layer, and large amounts of white steam gushed from the body surface.

Fourth Gear - Elastic Man.

"Is it this again?"

Kaido certainly remembered this form—back in the Flower Capital, this kid had used the same move to punch him.

That punch had decent power, but that was about it.

However, the aura emanating from Luffy now seems to be much stronger than last time.

"Kaido!"

Luffy's voice boomed from the sky, carrying a battle cry that exploded from the depths of his chest.

"I'm going to beat you this time!"

"Dog Model Dog Model - Ape King Gun!"

Luffy's right fist began to swell.

The massive, black and red Armament Haki-infused fist slammed down, while Luffy's legs in his Boundman form continuously compressed and released.

The massive Ape King Spear descended rapidly, and even before the punch was thrown, the sheer force of the fist shattered the surrounding clouds.

Kaido raised his dragon head, and the fiery clouds surrounding his body throbbed wildly. The huge blue dragon coiled up and crashed head-on into Luffy's fist.

"Bang--!!!"

The dragon's head and fist collided violently in mid-air.

A circular shockwave exploded from the point of impact, spreading wildly in all directions.

The shockwave tore a huge gap, hundreds of meters in diameter, through the surrounding clouds.

Moonlight poured down through the gap, illuminating the soldiers still fighting in the square below.

Several Beasts Pirates henchmen who were nearby were blasted away by the shockwave, crashing into the wall and losing consciousness.

Luffy's fist and Kaido's dragon horn were locked together, their forces clashing in mid-air.

Kaido's dragon head was many times larger than Luffy's entire body; from a distance, it looked like an ant struggling against a whale.

"Aaaaaaahh ...

A series of roars exploded from Luffy's throat.

His feet compressed rapidly back and forth in the air, each compression creating a circular shockwave. These shockwaves overlapped and pushed his fist forward.

A hint of surprise flashed in Kaido's vertical pupils.

This kid's strength is more than one level higher than when he was in the Flower Capital.

How could he have made so much progress in such a short time in Udon Prison?

"Hehehe—"

Kaido's mouth opened wide, about to say something, when a new burst of power exploded from Luffy's fist.

Luffy pressed his right fist against Kaido's dragon horn, slowly pushing it down.

One inch, two inches, three inches.

Kaido's dragon head began to droop under the pressure of this continuous force.

"Aaaaaahh ...

Luffy's roar grew louder and louder, and the frequency of his leg compressions increased.

The air behind him was stomped out in a series of visible white rings.

Each time a ring explodes, it pushes his body forward a little further.

Finally, Kaido's dragon body lost its balance.

The enormous dragon head was pushed downwards by Luffy's fist.

The enormous dragon body was also swayed off course.
