Chapter 30
The Size of the World
High above Onigashima, amidst shattered clouds and splitting skies, Kaido stared down at his daughter with disbelief burning behind his draconic eyes. Yamato stood victorious below, her enemies fallen, her Haki still raging like a storm that refused to calm.
For the first time in years, Kaido did not see a child playing at rebellion. He saw power—raw, undeniable, terrifying growth.
"What kind of nonsense is that…?" he muttered under his breath.
He had felt it clearly during the battle. No one in this world understood Yamato's true strength better than him. He had trained her, fought her, beaten her down countless times.
And yet what he witnessed today was not mere improvement—it was evolution.
"She fought of my All-Stars and who's who," Kaido growled. "one vs Four. And she grew stronger during the fight."
Her Haki had sharpened several times over. Her physique had hardened. Even her Devil Fruit mastery had advanced mid-combat. The final surge of Conqueror's Haki she released—those red eyes blazing with dominance—
It brought back a humiliating memory.
Ren noticed.
He chuckled.
"What? Remembered Garp chasing you, Big Mom, and Newgate?"
Kaido unconsciously nodded.
Then froze.
His eyes widened as he snapped toward Ren.
"You bastard—! No… wait. How the hell do you know that?" His voice turned sharp, dangerous. "Who the hell are you, kid?"
That incident had happened at God Valley.
Only a handful of people alive even knew fragments of what occurred there. It was buried under decades of silence and blood.
Ren laughed loudly, openly mocking him.
"Hahahaha! Your face looks priceless right now."
"You mother—!" Kaido roared, veins bulging. "Answer me!"
Ren tilted his head lazily.
"Do you remember your dream, Kaido? The one you lost while chasing the shadow of Joy Boy?"
Kaido's expression darkened.
"You do not understand, boy," he said slowly. "The world is bigger than you think. There are monsters hiding in the dark that even I cannot fight."
Ren's smile widened.
"Hmmm… are you talking about the shadow you fought at God Valley? The one that controlled Rocks? The one that made Garp and Roger join hands just to kill him?"
Kaido's pupils shrank.
"And yes," Ren continued casually, "the world really is bigger than you think. I even know someone who had the true Dragon Devil Fruit. Not some cheap Fish-Dragon imitation."
Kaido's killing intent exploded.
"You—! How the hell do you know so much? And who the hell are you calling cheap, you bastard?!"
Ren stepped forward in midair.
"Well," he said calmly, "your dragon form isn't even as big as his horns."
The wind stopped.
"Want to see how big the world really is, Kaido?"
Then it happened.
Ren's Beast Form began to grow.
It surpassed one thousand meters.
Then two thousand.
Three thousand.
Five thousand.
And kept growing.
Clouds scattered violently as a colossal Golden Monkey King towered in the sky, its fur blazing like sunlight forged into flesh. The very atmosphere trembled as his shadow swallowed Onigashima whole.
Kaido, in comparison, looked like a snake caught in a giant's grasp.
"This," Ren's voice boomed like thunder across the seas, "is how big the world is."
He grabbed Kaido by the neck.
With terrifying ease, he hurled him downward.
Kaido's massive body crashed into Onigashima, splitting mountains and shattering entire sections of the island.
---
On the distant coast of Wano, Morgans stared upward in absolute disbelief.
The Golden Monkey King was so enormous it blocked out the horizon itself. Even Kaido looked like nothing more than a writhing serpent in its hand.
Morgans tried to lift his camera.
The frame couldn't capture it.
It was too large.
For the first time in his career, the President of the World Economy News had no headline, no angle, no calculation.
He simply stared.
"That… that thing…" he whispered.
The sight did not inspire journalism.
It inspired primal fear.
---
Back on Onigashima, Ren shrank down into his Beast-Human form, golden aura crackling around him.
"Enough fun," he said lightly. "It's time to end this."
The clone had already taken the exhausted and blushing Yamato away from the battlefield.
Now there were no distractions.
Only two monsters remained.
Kaido rose from the rubble in his own Beast-Human form, blood trailing from his mouth but laughter rumbling from his chest.
"What the hell are you?" he demanded. "How can something like you even exist?"
Ren rested his staff on his shoulder.
"I told you. There's a true Dragon out there with that size. And he should be the strongest creature."
He looked at Kaido coldly.
"You, whose Haki stopped growing the day you lost to the world… you could never beat him."
Kaido went silent.
For a long moment, he did not attack.
He thought.
He believed Ren now.
He had felt that overwhelming size. That dominance. It was not illusion.
"Did I really forget who I was?" Kaido muttered to himself. "When did chasing Joy Boy's shadow become my dream? When did I start searching for hope? When did I lose my own ambition?"
Then—
He laughed.
"Worororororororo!"
The sound shook the island.
"So what?" he roared. "Even if there's a dragon that size—so what?!"
His Conqueror's Haki surged violently, black lightning exploding outward.
"I am Kaido! The Beast King!"
The sky cracked.
"I didn't survive this long to die chasing someone else's dream!"
His aura thickened, heavier than before.
Kaido had gained something from this battle.
He was not seeking a glorious death anymore.
The new era was coming.
And Kaido wanted to dominate it.
"Wororororo! Come then, brat! Defeat me! Wano and Yamato will be yours!"
He vanished.
"Thunder Bagua!"
The attack came faster than before.
But this time, there was joy in it.
Ren laughed wildly.
"Hahahaha!"
He swung his staff.
Their weapons didn't even touch, yet the sky split in two.
Onigashima trembled violently.
The shockwave spread across Wano, rattling mountains and shaking the seas.
Yamato, Denjiro, Ashura, Hyogoro, Hiyori, Kawamatsu and even Morgans turned toward the sky in horror.
The island was shaking from two men clashing.
"This is insane…" Denjiro whispered.
---
High above, Kaido and Ren laughed like madmen.
"Wororororo!"
"Hahahahaha!"
They vanished and reappeared in flickers, moving so fast that only afterimages remained.
Each collision amplified their Haki further.
Each strike refined their control.
Each clash shattered more of the sky.
Kaido stopped thinking about Yonko, about Joy Boy, about destiny.
The man fighting now was not the Captain of the Beast Pirates.
He was not a failed dreamer.
He was simply Kaido.
And he was enjoying every second.
"You're smiling too much, brat!" Kaido shouted mid-swing.
Ren blocked and countered.
"I'm enjoying this!"
"Enjoying fighting me?!" Kaido roared.
Ren replied, eyes blazing gold, "this is my first all-out battle!"
Kaido's grin widened.
"Then don't disappoint me!"
They collided again, black lightning erupting in spirals.
Ren felt it clearly now.
The Hito Hito no Mi, Model: Sun Wukong was resonating with his spirit. His blood boiled. His instincts sharpened. The divine monkey King's will aligned perfectly with his own battle-crazed joy.
"This is it…" Ren muttered.
Kaido charged once more.
"This is the battle I wanted!"
They struck simultaneously.
The impact split the heavens completely.
Onigashima shook.
Wano trembled.
The seas churned violently.
And both of them laughed as if the destruction itself was applause.
The true battle had only just begun.
