One Piece: Kaido's adopted son, starts with the Eight Gates Formation.

On the execution platform.

The heavy chains made a cold, crisp sound.

Two figures were roughly brought up by naval soldiers and made to kneel in the center of the crowd's attention.

Fire Fist Ace.

Straw Hat Luffy.

"That's... 'Fire Fist' Ace!"

"That guy next to me... is the 'Straw Hat Boy' who caused a ruckus on Enies Lobby a while back!"

"How...how did they all end up being brought up together?!"

Audiences around the world gasped in disbelief.

Fleet Admiral Sengoku, with heavy steps, walked to the very front of the execution platform.

He took a Den Den Mushi from the soldier's hand, and his usually stern face was now extremely solemn.

"Listen up, people all over the world!"

His voice, transmitted through the video Den Den Mushi, reached every corner of the world!

"Today, the one who will be executed here is not only the second division commander of the Whitebeard Pirates, 'Fire Fist' Portgas D. Ace!"

"Even more so..."

He took a deep breath, and with all his might, roared out that taboo name that was enough to overturn an entire era!

"The Pirate King, the biological son of Gol D. Roger!!"

boom!!!!!!!!

One stone caused a thousand waves!

The whole world was completely in an uproar at that moment!

"Wh...what?! Roger's son?!"

"What a joke! The bloodline of the Pirate King still exists in the world?!"

"Is...is this real?!"

Countless people have been rendered speechless because of this shocking secret!

However, the revelations from the Warring States period are far from over!

His finger suddenly pointed to the boy next to Ace, who wore a straw hat and had an indomitable look on his face.

"And him too!"

"Straw Hat Boy, Monkey D. Luffy!"

"His father is the most vicious criminal in the world! The leader of the revolutionary army—"

"Monkey D. Dragon!!"

Another bombshell!

Audiences all over the world were completely stunned!

The son of the Pirate King!

Son of a revolutionary!

These two men, who possess the most dangerous bloodline in the world, are actually brothers!

They were to be publicly executed at the same time!

"My God... Is the world about to change?"

"One's father is the Pirate King, the other's father is the leader of the Revolutionary Army... These two brothers' backgrounds are just too incredible!"

"But... speaking of the second generation, I feel like that 'Demon Child' Lynn is still the fiercest?"

"Indeed! His father is Kaido, and he's as strong as a monster, able to kill even Celestial Dragons without hesitation! Compared to him, these two seem to fall short..."

Discussions rose and fell.

Revolutionary Army Headquarters, Baltigue.

Long stared intently at the screen at his son, who was being led to the execution platform. For the first time, a visible tension appeared on his perpetually icy face.

Sabo, standing behind him, had his fists clenched so tightly they turned white.

"Mr. Long..."

"This is troublesome."

The dragon's voice was incredibly hoarse.

"Without 'Ne Zha' Lynn, the biggest variable, being present to restrain us..."

"With Newgate alone, I'm afraid... the chances of winning are slim."

He knew very well that the Navy's deployment this time showed their determination to completely bury the Whitebeard Pirates here!

Just as the whole world was immersed in this enormous shock.

Glug glug glug...

Countless huge bubbles suddenly rose to the surface of the sea in Marineford Harbour!

next second!

Crash!!!

The sea broke open!

A massive, whale-like flagship, the "Moby Dick," burst forth from the seabed!

Following closely behind were dozens of ships belonging to the Whitebeard Pirates!

The Whitebeard Pirates have arrived!

"It's...it's Whitebeard!!"

"They're attacking from the seabed!"

The navy personnel in the square instantly became agitated!

"Gurala la la la..."

Whitebeard stood at the bow of the Moby Dick, holding a huge naginata, and let out his signature laugh.

His gaze swept across the entire square, over the 100,000 elite naval troops, over the three admirals, and finally landed on Sengoku on the execution platform.

"The Warring States period... how many years has it been since we last met?"

"I have nothing to say to you, you bastard!" Sengoku roared.

Marco the Phoenix, Jozu the Diamond, Vista the Flower...

Fourteen captains stood behind Whitebeard, each radiating an aura powerful enough to make the ocean tremble!

"Dad."

Marco's gaze swept quickly across the navy's ranks, but he didn't find the figure he most wanted to see, and also most feared.

"'Ne Zha' Lynn is not here."

The white-bearded man's eyes flickered slightly, a hint of barely perceptible regret flashing across them.

"Gurarara... What a pity."

"If Kaido's brat son were here too, this battle would be much easier."

He slammed the naginata in his hand heavily onto the deck!

"My lords!"

"Are you ready?!"

"Ohh ...

The earth-shattering battle roar resounded through the sky!

"Then..."

The white-bearded man clenched his fists tightly, and the muscles on his arms bulged like writhing dragons!

"Let's start the war!!"

He spread his arms wide and slammed them down hard into the air on either side!

Snap! Snap!

The atmosphere, like a mirror, shattered inch by inch!

A terrifying tremor instantly swept through the entire Marineford!

Tsunami!

A massive, sky-covering tsunami surged up from both sides of the harbor, crashing down on the Marine Headquarters!

War broke out!

……

Off the coast of Marineford.

On a dilapidated raft, the members of the Blackbeard Pirates felt the earth-shattering tremor, their expressions varying.

"Thief! Hahahaha!"

Blackbeard Teach let out his signature maniacal laugh.

"Old man with the white beard...you really are getting old!"

His eyes were filled with disdain and contempt.

"This level of attack is far inferior to the power of a casual strike from that 'Demon Child' Lynn!"

He suddenly stood up, looking at the Marine Headquarters which was in complete chaos, his eyes burning with boundless ambition!

"However, I must thank you... Without you holding back the Navy, it would have been really difficult to enter Impel Down..."

"My lads! Now!"

"Hit that warship! Our target is Impel Down, the underwater prison!"

He spread his arms wide, facing the sky, and let out a mad roar.

"Thief! Hahahaha!"

"My era is about to begin!"

"The chance to surpass Whitebeard! To surpass Kaido! Even to surpass that 'Demon Child' Lynn is right before our eyes!!"

……

A new world, a world of nations.

On Whole Cake Island, Charlotte Linlin is watching this grand "performance" through a giant screen.

"Mmmmmmmm..."

She let out a delightful laugh, her mouth full of dessert.

"They're fighting! They're fighting! What a wonderful tea party!"

She looked at the chaotic battlefield on the screen, her eyes filled with excitement.

"But... if that brat Lynn were here too, this scene would definitely be even more exciting!"

……

Wano Country, Oni Island.

The huge banquet hall was filled with the smell of alcohol.

"Ooh o ...

Kaido, watching the devastating tsunami on the screen, excitedly slammed the gourd in his hand onto the ground!

"This is the best banquet ever! The best war ever!"

His enormous body began to uncontrollably transform into blue dragon scales!

"I'm going to join the fun too!!"

boom--!

A sky-covering azure dragon crashed through the roof of Ghost Island and soared into the clouds!

"ember!"

Kaido's voice, like rolling thunder, resounded across the sky.

"If that kid Lynn gets back, make him go to Marineford right away!"

"I'm going to be there, fighting a truly satisfying war alongside him!!"

however.

Kaido in his Azure Dragon form hadn't flown very far from Wano Country.

A large, red ship with a dragon head carved on its prow appeared silently before him.

"The Red-Haired Pirates?!"

Kaido's dragon face showed an impatient expression.

"Shanks! You trying to stop me?!"

At the bow of the ship, Shanks, the red-haired man, rested his hand on the famous sword "Griffin" at his waist, calmly gazing at the giant dragon before him.

"Kaido."

His voice was calm, yet carried an undeniable power.

"You already have such an outstanding son."

"You don't need to get involved in this war anymore, do you?"

"Ooh o ...

Kaido let out a deafening burst of maniacal laughter.

"Stop talking nonsense!"

"Anyone who dares to stop me, I'll kill them!!"

The terrifying dragon breath and the domineering aura of Conqueror's Haki intertwined instantly!

……

The Holy Land, Mary Geoise.

Between power.

The five elderly people were calmly watching Marineford, which had been transformed into a hellish landscape, on the screen.

Their faces remained completely expressionless.

It was as if, in their eyes, that war, which was enough to overturn the world, was nothing more than a boring drama.

"The entire Whitebeard Pirates..."

The blond Five Elders picked up the black tea in front of them, took a small sip, and spoke indifferently.

"His threat level is far less than that of 'Demon Child' Lynn alone."

"The real trouble isn't the white beard."

He put down his teacup, his deep eyes gazing out the window.

"But it's that brat..."

"Where exactly are we now?"

……

And in a luxurious room at the Navy Headquarters.

Lynn was sitting cross-legged on the soft carpet, with a small table in front of her.

The table was piled high with all sorts of snacks and desserts.

Before him was a giant heart-shaped mirror, conjured by Hancock's powers.

The mirror clearly showed the battle situation at Marineford in real time.

"Click...click..."

Lynn was stuffing potato chips into her mouth while watching the live stream with great interest.

When he saw the white-bearded man shatter the atmosphere with a single punch, creating a massive tsunami, he nodded seriously.

"Hmm... the strength is alright."

"It's a pity Whitebeard is getting old, otherwise, with that move alone, taking down half of Marineford wouldn't be a problem..."

He grabbed a handful of popcorn, stuffed it into his mouth, and mumbled indistinctly.

"Go ahead and fight."

"The more fiercely they fight, the better."

"When you've all fought enough..."

A hint of anticipation flashed in his innocent eyes.

"It's my turn to take the stage."
