CHAPTER 154

Alastor switched seamlessly to the advanced technique of Ryuo—the flowing sakura haki. Unlike standard Armament Haki, Ryuo bypasses surface defenses and directly strikes the interior, disrupting the very core of an opponent's body.

But what truly set Alastor apart was his unique physiology. His internal organs were as durable as his epidermis, an unprecedented trait unmatched even by Kaido, the so-called "Strongest Creature."

When Alastor's attack landed, his Ryuo broke through Kaido's defenses, bypassing his dragon scales and causing internal damage. A shockwave rippled through Kaido's massive frame, forcing blood to spill from his mouth.

Kaido glared at him, his eyes narrowing dangerously.

"This brat... he's mastered Ryuo?" Kaido thought, his mind racing. "It actually hurts... but it's not enough to stop me."

Though the attack stung, it was barely a dent in Kaido's seemingly infinite stamina and durability.

"Bastard," Kaido roared, raising his colossal kanabo, "don't think you're the only one who can use Ryuo!"

The kanabo descended with terrifying force, enveloped not in Conqueror's Haki but Ryuo—a testament to Kaido's mastery of the technique.

Kaido's Ryuo wasn't just advanced—it was leagues beyond what Alastor had unleashed.

The weapon struck true, smashing into Alastor's torso. A loud boom echoed across Onigashima as the ground beneath Alastor cracked and crumbled. Blood erupted from his mouth as he staggered under the force of the blow.

Kaido grinned triumphantly.

"That should keep you down, brat," he growled. "Let's see you recover from that!"

Kaido was confident that his Ryuo had bypassed Alastor's unparalleled surface defense and wreaked havoc on his internal organs.

But Alastor remained standing.

He wiped the blood from his lips, a smile tugging at the corners of his mouth.

"Close... but not quite," Alastor said, his tone almost mocking. "That was the strongest internal strike I've ever taken. It nearly burst my organs. But thank you, father-in-law. Your Ryuo is leagues ahead of mine, and I've already learned so much. I can probably match it in my next attack."

Kaido's grin faltered, replaced by a stunned expression.

"What?!"

Kaido stared, dumbfounded. Alastor not only survived but appeared to be learning in real time.

"Are you using me as a training dummy, brat?" Kaido roared in disbelief.

In truth, Kaido had long unknowingly perfected the art of teaching through combat. His brutal, relentless assaults had forged Yamato into a formidable warrior. Now, Alastor was proving to be another product of Kaido's "unintentional mentorship."

"Oi, Kaido! Don't forget about me!"

A flash of white fur and icy blue light interrupted Kaido's rage. Yamato lunged forward, her kanabo infused with Conqueror's Haki, Armament Haki, and her ice powers.

"Phantom Ice Blade!"

Her weapon struck Kaido's jaw with incredible force, sending him hurtling across the battlefield and crashing hundreds of meters away.

Yamato landed beside Alastor, her breath steady despite the intensity of the fight.

"Nice timing," Alastor remarked, cracking his neck.

"You good?" Yamato asked, her voice laced with concern.

"This? Barely a scratch," Alastor replied, flexing his muscles. "I can take hits like that three or five more times without breaking a sweat."

"Good," Yamato smirked. "Then let's hit him harder."

The duo charged forward.

Lightning surged under Alastor's feet as he launched himself toward Kaido. His sword, Sandai Kitetsu, was now fully enveloped in Ryuo. The black and red energy spiraled along the blade, forming a ribbon of destructive power.

"Thanks to you, father-in-law," Alastor muttered, his grin wide, "my Ryuo has reached a new level."

He raised his blade, its menacing aura darkening the sky.

"Ghost Aura, One Sword Style: Asura, Purgatory Demon-Sealing Slash!"

The air seemed to tremble as Alastor's blade struck out in a blur. His attacks were so fast that only afterimages were visible, each strike piercing through Kaido's scales and into his massive frame.

Kaido grunted as blood erupted from dozens of internal wounds.

Yamato was right behind Alastor, her kanabo smashing into Kaido with unrelenting force. The combination of her physical power, ice manipulation, and Conqueror's Haki made her a devastating force to reckon with.

Kaido staggered under their onslaught.

From a distance, the Tobiroppo and other members of the Beasts Pirates watched in stunned silence.

King narrowed his eyes, his usually composed demeanor cracking.

"This... this isn't a fight," he murmured. "This is a war between monsters."

Who's-Who swallowed hard. "Master Yamato and that lunatic... they're pushing Boss Kaido back!"

"Unbelievable..." Sasaki muttered.

Page One couldn't help but grin. "I told you, Brother Alastor is unstoppable!"

Ulti, standing nearby, crossed her arms and scoffed.

"Don't get ahead of yourself, Pay Pay. Those two may be strong, but Kaido's still Kaido."

Under the oppressive skies of Onigashima, the battle raged on. Alastor and Yamato, side by side, clashed with Kaido in a relentless storm of power, haki, and sheer determination.

For the first time, the very foundation of Ghost Island seemed to quake under the weight of a fight that could shape the future of the seas.

At this moment, an almost comedic yet deeply intense scene unfolded atop Onigashima: a daughter and her son-in-law working together to overwhelm their old father. But instead of familial warmth, the air crackled with tension, passion, and raw power.

Every strike carried a mix of filial determination and defiance, and even the heavens seemed moved by the scene. Thunder rolled and lightning illuminated the battlefield as Alastor's blade and Yamato's kanabo struck Kaido with unrelenting force.

Boom!

Kaido was sent flying, blood spraying through the air like crimson rain.

Kaido crashed into the ground like a meteorite, the impact threatening to shatter the very foundation of Onigashima. Dust and debris swirled, obscuring the towering figure of the "Strongest Creature."

From within the smoke, Kaido rose, shaking his massive frame. His head throbbed, his vision spun, and the deep gashes across his chest oozed blood.

For any other emperor of the sea, such injuries would have been debilitating, reducing their fighting capacity by half. But Kaido was no ordinary being. His Mythical Zoan Azure Dragon fruit had long since awakened, granting him near-limitless recovery.

The dizziness subsided, the wounds on his chest closed, and even his internal damage began to repair itself. Within moments, Kaido stood at full strength once more.

With a menacing glare, he roared, "You brats! This pain… it's been decades since I've felt this!"

Images of legendary figures like Roger, Whitebeard, and Shanks flashed through Kaido's mind. The sheer strength of Alastor and Yamato's combined assault was enough to push him to acknowledge them—not as children, but as true warriors.

Kaido's thoughts drifted to the past. He had once allowed Yamato to govern Wano, despite her rebellious spirit. In his mind, her leadership and the samurai she trained would one day become tools under his rule. Wano, its people, and its warriors were all meant to fuel his vision of an endless war.

But now, Yamato and Alastor stood against him as equals, defying not just his authority but his very ideology.

Kaido felt a strange mixture of pride and fury.

"These two... Yamato, my seed, and Alastor, my son-in-law… Perhaps they could bring forth a new era. Perhaps they could even become Joy Boy," Kaido thought bitterly.

Still, their defiance infuriated him. "You dare oppose me when you could join me in my conquest? Together, we could rule the world in eternal war!"

Kaido's monstrous gaze fell on the two. His sharp teeth gleamed as he growled, "One last chance: live for me, and help me launch the greatest war this world has ever seen!"

Yamato stepped forward, her eyes blazing with resolve.

"Stop dreaming, Kaido!" she shouted. "I will defeat you here and now!"

Alastor, calmer but equally resolute, added, "Father-in-law, I understand your pain and your past. But I cannot support your vision of a world ruled by fear and suffering."

He leveled his blade at Kaido, his voice firm. "The innocent shouldn't have to live under constant oppression. Power should protect, not dominate. That's where you and I differ."

Kaido's laughter echoed like thunder.

"Foolish boy! Only suppression and fear can maintain order. Without them, the world falls into chaos! Do you truly believe your childish ideals can change this cursed world?"

The tension thickened as Kaido spread his arms wide, his laugh growing louder.

The skies above Onigashima churned as Kaido's aura exploded outward. His overwhelming Conqueror's Haki radiated in waves, darkening the heavens and shaking the earth.

Even those far below the battlefield felt its weight. The Beast Pirates, hardened warriors accustomed to Kaido's power, found themselves trembling.

"What's happening up there?" one soldier asked, his voice quivering.

"Boss Kaido… he's fighting someone. But who could stand against him?"

On the roof, Kaido stood like a living storm, his dragon scales shimmering and his bloodlust palpable.

Yamato tightened her grip on her kanabo.

"We're not backing down, Kaido!"

Alastor's blade pulsed with energy as he prepared to strike.

"I'll prove to you that strength doesn't have to come from fear. Let's settle this!"

The two launched themselves at Kaido once more, the clash of their wills creating a storm that would be remembered as a turning point in the battle for Wano.
