[OP Marine Officer Luffy] Chapter 491- 495

Chapter 491: Kaido: Is This Still My Idiot Child?!

The climate in the New World was notoriously fickle—Kaido had witnessed countless instances of extreme weather throughout his decades at sea. It wasn't uncommon for clear skies to transform into hailstorms within seconds, or for calm seas to erupt into typhoons without warning.

But something about this particular thunderstorm triggered Kaido's instincts. He paused mid-bite, his massive brow furrowing as a realization struck him.

"No... this isn't natural," he muttered, lowering his skewer of meat. "I'm currently in the White Sea at an altitude of over 7,000 meters."

Kaido had journeyed to Sky Islands numerous times over his long career as a pirate. The White Sea had distinctive weather patterns, and while they could be unpredictable, they rarely manifested as conventional thunderstorms like those in the Blue Sea below.

"Will there be thunderstorms over the White Sea?" he questioned aloud, suspicion growing with each passing second.

Before he could pursue this line of thought further, the weather itself provided a decisive answer to his query.

CRACK! BOOM!!!

An ear-splitting thunderclap shook the cloud-house, followed immediately by a blinding bolt of lightning that struck the structure with unerring precision. This was no random act of nature—the lightning had been directed, targeted specifically at Kaido's floating sanctuary.

The impact sent Kaido stumbling backward, his massive frame momentarily losing balance as the cloud-house began to disintegrate around him. With rage contorting his features, he roared the name of the only person he knew capable of such a precise lightning attack.

"DAMN YOU, MARINE BRATTTTT!!!"

His enraged bellow echoed across the sky as the cloud-house exploded into fragments, its structure completely obliterated by the lightning strike. The destruction of his floating platform left Kaido with nothing to stand on, sending the Emperor plummeting through the White Sea and toward the Blue Sea far below.

For more than ten seconds, a humanoid figure could be seen in free fall—a massive shape hurtling downward at terminal velocity. Directly beneath his trajectory lay a small, uninhabited island—one of many scattered throughout the waters surrounding Wano Country.

Kaido's enormous body crashed into the island with catastrophic force. The impact generated a shockwave that rippled through the entire landmass, creating fissures in the ground and uprooting trees for hundreds of meters in every direction. At the point of impact, a perfect crater formed—a bottomless pit that seemed to extend deep into the island's core.

For several long moments, the pit remained silent and still. No movement, no sound emerged from its depths.

"That guy Kaido... he didn't actually fall to his death, did he?" a voice questioned from the edge of the newly formed crater.

Luffy stood at the rim, flanked by his assembled team. Beside him, Yamato gazed into the darkness with an expression that mixed hope and skepticism. Despite being Kaido's biological child, she held no filial affection for the tyrant who had imprisoned and tortured her throughout her youth.

"Even for someone as durable as my father," Yamato observed, hefting her kanabo, "falling from an altitude of 7,000 meters should cause significant damage. Perhaps we—"

Before she could complete her assessment, the ground beneath their feet began to tremble violently. The vibrations intensified rapidly, culminating in an explosion of debris as a dark shadow erupted from the pit, launching upward with terrifying speed before crashing back down to earth just meters from where the Marine group stood.

When the dust settled, it revealed Kaido standing before them—muddied and disheveled, with his clothing torn in various places, but otherwise appearing completely unharmed. Despite the catastrophic fall from an altitude that would have killed virtually any other being, the Emperor showed no signs of either external or internal injuries.

More remarkably still, despite being taken by surprise and plummeting through both the White and Blue Seas, Kaido had managed to retain his grip on his signature weapon—the legendary kanabo known as Hassaikai, or Eight Trigrams.

With his massive club in hand, Kaido strode forward purposefully. The sheer pressure of his presence—his overwhelming Conqueror’s Haki leaking out uncontrollably—caused Viola and Mansherry, the more support-oriented members of Luffy's team, to visibly struggle under its weight.

Kaido's piercing gaze swept across the group of seven people arrayed before him. First, his eyes locked onto Luffy—the "little Marine brat" who had stolen his territory and humiliated him. His teeth gritted at the sight of his nemesis, but then his attention was captured by an unexpected figure standing among the Marines.

"Yamato?!" Kaido bellowed, his expression shifting from rage to genuine shock. "Why are YOU here, you idiot?!"

The question erupted from him almost involuntarily, a father's instinctive response rather than a calculated reaction. But as the initial surprise faded, Kaido noticed details that compounded his confusion—namely, the Marine coat draped over Yamato's shoulders and her dramatically altered appearance.

While female fighters in the pirate world often battled in impractical attire like skirts and high heels, Yamato's current outfit represented a seismic shift from her previous style. She wore a fitted white short-sleeved top embellished with the Marine insignia, paired with a light blue high-waisted pleated miniskirt that replaced her traditional hakama. Instead of her usual wooden sandals, she now sported elegant white stiletto heels that accentuated her height.

But these fashion changes weren't what truly stunned Kaido. What left him genuinely speechless was the transformation in her presentation.

His child Yamato—who had for years insisted on being addressed as a man, who had declared herself to be the reincarnation of Kozuki Oden, who had rejected all aspects of conventional femininity—had applied makeup. Delicate eyeliner accentuated her eyes, complemented by subtle eyeshadow. Her lips were tinted with a pale pink color, and her nails were manicured and polished.

"Is this still my idiot child Yamato?!" Kaido thought, dumbfounded. "Where did you hide the real Yamato?!"

While Kaido stared in disbelief, Yamato herself had no interest in his confusion. She hefted her own kanabo—smaller than Kaido's but still a formidable weapon—and pointed it directly at him, her eyes blazing with years of accumulated hatred.

"Damn you, Kaido," she snarled, dispensing with any familial terms. "I finally have my chance. This time I'll kill you myself and avenge the people of Wano Country!"

These unfiliual words snapped Kaido back to reality, pulling him from his shocked stupor. With mixed emotions swirling within him, he untied the gourd of sake that had somehow survived both the lightning strike and his subsequent fall. Tilting his head back, he gulped down several mouthfuls of the potent alcohol.

"Haaah~" he exhaled, the familiar burn of sake momentarily distracting him from the bizarre situation. After shaking the now-empty gourd, Kaido callously tossed it aside.

"WORORORORO~" His distinctive laughter boomed across the devastated landscape. "I thought the electric shock had caused hallucinations, but this is actually real!"

He turned his attention to Luffy, addressing him with a mixture of sarcasm and genuine curiosity. "Hey, kid, how exactly did you manage to transform Yamato like this? You've accomplished something even I couldn't achieve in twenty years!"

Luffy, who had been standing with his arms crossed, analyzing the most effective strategy against Kaido, responded in a deliberately neutral tone.

"What, are you surprised?" he replied with calculated indifference. "If you knew I was your son-in-law now, your jaw would hit the ground."

"Haaaa?" Kaido emitted a strange, strangled sound, his eyes darting rapidly between Luffy and Yamato. Looking more closely at his child's features, he indeed noticed a newfound gentleness and confidence that hadn't been present before—a stark contrast to the perpetually angry, Oden-obsessed youth he remembered.

For perhaps the first time in decades, Kaido of the Beasts found himself genuinely speechless.

Chapter 492: Father and Daughter Battle, Photography Team is Ready

Just as Luffy had predicted, Kaido's jaw nearly dropped to the ground in shock at the implications of the Vice Admiral's statement.

"No," the Emperor sputtered, visibly struggling to process this information. "Is this still the New World? What did your lightning do to me?!"

Kaido would sooner believe that he had been struck dead by lightning and ascended to heaven than accept that Yamato had not only fallen in love with someone but had become a Marine's wife—especially the very Marine who had humiliated him and stolen his territory.

After a prolonged silence during which his mind raced through various scenarios—all of them preferable to the reality before him—Kaido finally regained his composure.

He regarded Yamato with a complicated expression, a mixture of parental concern, bewilderment, and underlying anger swirling in his eyes. But then his gaze hardened, returning to the implacable determination that had made him feared across the seas.

"Yamato," he began, his voice uncharacteristically measured. "When you were captured by the Marines before, I gave you a chance to return to us. I hoped you would come to your senses and return willingly."

He straightened to his full intimidating height, the massive horns atop his head seeming to scrape the sky itself. "Now, I'll offer you one final opportunity—come back with me. As long as you abandon this foolishness..." His voice faltered momentarily before continuing, "As long as you stop claiming to be Kozuki Oden, I will still reserve your position as Governor of the Beast Pirates."

When her father mentioned her previous obsession with Kozuki Oden, Yamato's face flushed crimson with embarrassment. That chapter of her life—when she had blindly worshipped and imitated the samurai—now seemed like a distant, childish phase she had outgrown.

"Idiot!" she snapped, the familiar hostility returning to her voice. "I don't care about Kozuki Oden or any of that nonsense anymore! Don't mention him in front of me—I am Yamato now, and I will only be Yamato!"

Kaido's eyes widened with surprise and a glimmer of hope. After decades of frustration over his child's identity crisis, hearing Yamato finally accept her own name caused an unexpected surge of paternal satisfaction. Perhaps, he thought, his daughter had finally matured beyond her childish fixations.

But Yamato's next words extinguished that hope as quickly as it had ignited.

"Give up on your delusions," she declared firmly. "I won't return with you. I have my own dreams now—I want to help Luffy become a Marine Admiral, and someday, I aim to become one myself!"

"You ungrateful brat!" Kaido roared, his patience finally shattering. "You always side with outsiders! Can't you show even the slightest consideration for your own father?!"

This rare display of emotional vulnerability from Kaido revealed the genuine pain beneath his fearsome exterior. Yamato was indeed his biological daughter, yet throughout her life, she had consistently opposed him because of her admiration for two men: first Kozuki Oden and now Monkey D. Luffy.

Coincidentally, both of these individuals had not only defied Kaido but had inflicted physical and psychological wounds that still burned. The samurai had scarred him during their legendary battle, while the young Marine had humiliated him and driven him from Wano.

Kaido's mind flashed through the tumultuous history with his daughter. Yamato had been a typical little girl briefly in her earliest years, but soon began showing signs of rebellion.

At the age of eight, she had been captivated by stories of Wano's samurai—particularly Oden—and had fallen into what Kaido considered mindless hero-worship. Now, just when she had finally outgrown that phase and Kaido thought he might experience some semblance of normal father-daughter relationship, another figure had appeared and completely led her down a path of continued opposition to him.

"Was Yamato born specifically to oppose me?" Kaido thought bitterly. "Is this some cruel joke of fate?"

As these painful reflections swirled through his mind, Kaido's remaining patience evaporated. He was finished with conversation. With a furious growl, he hefted his massive kanabo, determined to teach his disrespectful daughter a lesson she wouldn't forget.

Yamato met his challenge without hesitation. Gripping her smaller version of the kanabo with both hands, she lunged forward with explosive speed, moving like an arrow released from a bow.

Her weapon gleamed with the blackened sheen of advanced Armament Haki, specifically employing the internal destruction technique that could damage opponents from within. The kanabo crashed against Kaido's defense with tremendous force.

Kaido's eyes narrowed with ferocious intensity. He stomped his left foot heavily into the ground, anchoring himself against the impact. Simultaneously, he gathered his immense strength into his right arm, swinging Hassaikai upward in a diagonal arc. His weapon, similarly coated with potent Armament Haki, collided with Yamato's kanabo with earth-shattering force.

As their weapons connected, both father and daughter glanced briefly at the uninhabited island beneath them—a landmass Luffy had strategically pulled from nearby waters to serve as their battleground. Kaido wondered if this small island could withstand the destruction their confrontation would inevitably cause.

"Thunder Bagua!" they shouted in unison, each executing the signature technique that had been passed from father to daughter.

In that instant, the ground beneath their feet began to fracture, spreading outward in a spider-web pattern from the point of impact. The terrifying shockwave generated by their clash sent debris and dust billowing in all directions.

Luffy calmly raised his hand, using his own Haki to disperse the approaching wave of dust and pressure.

"Luffy," Koala stepped forward, concern evident in her voice as she observed the unfolding battle. "Shouldn't we intervene? Yamato can't possibly be a match for Kaido on her own."

Luffy watched as Yamato continued to exchange blows with her father, noting how she was gradually being forced onto the defensive despite her impressive showing. A knowing smile played across his lips.

"Yamato is naturally no match for Kaido at full strength," he acknowledged. "But she's been suppressing these feelings for so long. If we don't allow her this opportunity to confront him directly, we'll all suffer from her frustration later."

He turned to address the two least combat-oriented members of their team. "Viola, Mansherry—stay well back and remain behind us for protection. When Yamato reaches her limit, Mansherry, your healing abilities will be essential to restore her strength."

The tiny fairy princess nodded solemnly, her wings fluttering with nervous energy.

"Viola," Luffy continued, "focus on being our photographer. Capture clear images of our combat with the Emperor—these will serve as evidence of our victory over one of the Four Emperors. Your promotion might depend on the quality of these records."

The two women nodded in understanding. Viola, the princess of Dressrosa, made an affirmative gesture before positioning her Visual Den Den Mushi at a safe distance. With her Glare-Glare Fruit abilities, she could observe and record the battle from multiple angles simultaneously, creating a comprehensive record of their engagement with the Emperor.

Satisfied with these arrangements, Luffy turned his attention back to the ongoing battle. He had already formulated a strategy: after Yamato had exhausted herself against her father, Hancock, Koala, and Vice Admiral Gion would take turns engaging Kaido, each showcasing their unique fighting styles and abilities.

This approach would serve multiple purposes—wearing down the Emperor gradually, gathering intelligence on his current capabilities, and creating a record of coordinated Marine tactics against a Yonko-level threat.

Only after these preliminary engagements would Luffy himself step forward for the final confrontation. His primary objective extended beyond mere victory—he intended to study Kaido's masterful use of Conqueror’s Haki during their battle, hoping to overcome his own plateau by learning from the Emperor's techniques.

Honestly what he want is to copy Luffy from the Original canon and have Kaido-sensei help him be stronger.

If he had traveled thousands of miles for this confrontation, Luffy was determined to extract every possible benefit from it.

Chapter 493: Mutual Breakthrough - The Stubborn Daughter and Her Unyielding Father

After being swept away by Kaido's kanabo once again, Yamato abandoned the idea of a pure physical contest. With a determined gleam in her eyes, she decisively transformed into the human-beast form of her Devil Fruit, Dog-Dog Fruit, Model: Okuchi-no-Makami.

"You stubborn old dragon!" Yamato shouted, her voice carrying across the battlefield. "Let me show you the results of my training these past months!"

Her white fur gleamed under the sun as azure flames of divine power flickered around her form. "In these six months since we last fought, I haven't been standing idle!"

Kaido casually rested his massive kanabo on his shoulders. When he heard Yamato addressing him, his face darkened considerably, veins bulging on his forehead.

"Idiot child," he growled, "who are you calling stubborn? Don't forget that you inherited that very same stubbornness from me..."

Before Kaido could finish his scolding, Yamato's figure had already vanished from sight, only to reappear rushing toward him with frightening speed.

Seeing this, Kaido narrowed his eyes in recognition. "Soru? One of the Rokushiki? You even learned this from those Marine dogs." A small, almost imperceptible smile tugged at the corner of his lips. "But if you think mastering just the Rokushiki will be enough, you're severely underestimating me!"

Kaido immediately swung his kanabo downward, preparing to unleash his signature move—Thunder Bagua.

But just before his weapon descended, Yamato suddenly leapt high into the air. In mid-flight, she leveled her body and raised her own kanabo, aiming its tip directly at Kaido's chest where his heart lay beneath layers of nearly impenetrable muscle.

"Kanabo-Gun: Baku Zen!" Yamato roared.

Combining the lightning speed of Soru with the aerial maneuverability of Geppo, enhanced by the supernatural swiftness granted by her Devil Fruit, Yamato successfully targeted Kaido's heart before he could fully react.

In that critical instant, her kanabo struck Kaido's chest with such terrifying force that it caused a slight indentation in his seemingly invulnerable skin. The tremendous impact sent shockwaves across the battlefield, kicking up clouds of dust around them.

Yet most of the force seemed to dissipate against his tough dragon scales and iron-like muscles. To an onlooker, the attack might have appeared ineffective.

But only Kaido himself knew the truth. Yamato had adapted the Rokushiki technique of Shigan, the Finger Pistol, to her kanabo. Using precise control, she'd focused all the impact into a single point, then immediately infused advanced Armament Haki into the tip of her weapon, directing it inside his body upon contact.

The foreign Haki now circulated within him, specifically targeting his heart. Blood vessels and tendons in that vital area contorted as the concentrated Haki tunneled through his massive form, eventually bursting out from his back in a focused beam of power.

Even after exiting Kaido's body, the force of her attack carved a tunnel in the ground behind him—a fist-sized hole extending more than ten meters into the earth.

The penetrating power of Yamato's technique was undeniable. As expected, Kaido spat blood after receiving this precise blow—something that hadn't happened in years of their battles.

Yamato couldn't help but let a triumphant smile appear on her face. "How's that, old man?"

But her victory was short-lived.

In that moment, a powerful gust of wind erupted as Kaido used his draconic abilities to blow away the smoke and dust. With a single powerful movement, he pulled himself from the crater Yamato's attack had created.

BANG!

His dragon claw shot out with blinding speed, grabbing Yamato firmly by the head.

Luffy and the others watching the fight all furrowed their brows in concern. Viola and Mansherry even gasped in horror, covering their mouths with their hands.

Yet despite their clear worry, none of Luffy's companions stepped forward to intervene. This was Yamato's battle—one she needed to fight herself.

"Yamato, my foolish daughter," Kaido rumbled, blood still trickling from the corner of his mouth. "It seems you have indeed made considerable progress during this time."

His grip tightened slightly as his eyes reflected a complex mixture of pride and disappointment. "This is the first time you've genuinely wounded me in all these years."

He lifted her higher, meeting her defiant gaze. "But it's still not enough. If you truly wish to defeat me, you remain far too weak!"

As he spoke, purple-red lightning began to crackle around Kaido's massive hand, dancing across his skin with destructive potential.

He hoisted Yamato high above his head with a single arm, and then brought her down with catastrophic force.

"Raimei Hakke!" Kaido roared. "THUNDER BAGUA!"

BOOOOOM!!!

The moment Yamato's body slammed into the ground, the entire island began to shake violently as if struck by a cataclysmic force. The epicenter of their battle erupted, raising a mushroom cloud of debris that towered into the sky.

Viola and Mansherry watched in terror, their faces pale with fear.

"Yamato!" Mansherry cried out. "Is she...is she dead?"

"Don't worry," Gion replied in a surprisingly relaxed tone. "She won't die from something like that. At most, she'll suffer a few broken bones." There was even a hint of dark humor in her voice.

Beside her, Boa Hancock maintained a serious expression. Though her strength was comparable to Yamato's, she didn't possess the same physical resilience or the supernatural durability granted by a Mythical Zoan fruit.

Hancock knew that if she were caught by Kaido and struck with such overwhelming force, she might indeed suffer severe injuries as Gion had casually suggested.

Gion's nonchalant words frightened Koala, Viola, and Mansherry, their complexions growing increasingly pale. Viola and Mansherry were just spectators, but Koala's situation was different.

When she considered that she might have to face Kaido in battle herself later, her legs began to tremble involuntarily. She was only seventeen—practically still a child compared to these monsters of the New World. If Kaido attacked someone of her caliber with such devastating power, death seemed the only possible outcome.

Luffy noticed the panic and fear growing in the hearts of the three women, especially Koala. He turned to offer reassurance, his voice calm and confident:

"Don't worry," he said with absolute certainty. "Yamato is fine. Don't underestimate her."

The unwavering trust in his words caused them to swallow their fears and turn their attention back to the center of the destruction, where the mushroom cloud still billowed upward.

As if in response to Luffy's faith, a blast of frigid air suddenly erupted from within the cloud.

"Namuji Hyoga!" Yamato's voice rang out clear and strong.

After releasing her counter-technique almost face-to-face with Kaido's devastating attack, Yamato leapt out of the crater. With several nimble backward jumps, she created distance between herself and the Yonko.

Koala and the others looked quickly toward her, relief washing over their faces. They could see shards of broken ice falling from Yamato's body as she moved.

This was her defensive technique "—a skill that created a layer of ice armor around her body as protection. She had relied on this frozen shield, reinforced with Armament Haki and the Tekkai iron body technique, to withstand Kaido's earth-shattering blow.

But even with these formidable defenses, Yamato couldn't completely negate the massive impact. Her internal organs protested painfully, and she fought to maintain her composure as she faced her father once more, determination burning in her eyes.

Chapter 494: Enemy's True Intent - Yamato Awakens Her Dominance

Blood continued to seep from the corners of Yamato's mouth, her wolf-like features contorted in pain. It was evident she had suffered serious internal injuries from Kaido's devastating attack. Yet, wiping the crimson streak from her face, she seemed unconcerned with her wounds. Instead, her brow furrowed in deep concentration.

"This power..." she muttered, eyes narrowing as something stirred within her. "Is this the manifestation of Conqueror's Haki? I feel something resonating inside me."

Her voice grew more certain as understanding dawned. "It seems that as long as I channel it through my will, I can harness it..."

Hearing her instinctive musings, Kaido's expression froze momentarily in surprise before darkening further. A complex mixture of pride and frustration flashed across his imposing features.

That's right, he thought. It's this kind of raw talent that anyone could see with their naked eyes.

This child had awakened her Conqueror's Haki at the mere age of eight, and her strength had grown exponentially despite enduring the harshest conditions since childhood—hunger, isolation, and constant battles for survival within the Beast Pirates' fortress. Such exceptional potential was entirely befitting of Kaido's offspring, a fact that secretly filled him with satisfaction.

But unfortunately, this stubborn child had never aligned with his vision.

All Yamato ever did was scheme against him, dreaming of escape and freedom, completely wasting such magnificent potential! If only she could be more obedient. Even though she was a daughter rather than the son he'd initially wanted, Kaido would have gladly bestowed upon her the position of All-Star within the Beast Pirates, perhaps even his successor.

But fate had other plans. The more Kaido reflected on this reality, the more his anger intensified. The sight of his wayward daughter now standing against him, wearing a Marine coat no less, became increasingly intolerable.

Since you refuse to listen, he resolved grimly, then I no longer need such a daughter!

"Raimei Hakke: CONQUEST!" Kaido roared.

With terrifying speed that defied his massive size, Kaido launched forward. His kanabo, now coated in the dark crackling energy of advanced Conqueror's Haki, whistled through the air toward Yamato.

This attack carried no restraint whatsoever—Kaido was aiming directly for her head with killing intent.

Yamato sensed the deadly danger approaching. Her body instantly tensed, every hair standing on end as primal survival instincts kicked in. Without conscious thought, she twisted away from her original position with supernatural agility.

But Kaido's eyes flashed crimson as his advanced Observation Haki predicted her evasive path. With masterful precision, he altered his kanabo's trajectory from a downward smash to a sweeping arc that would still intercept her movement.

In the blink of an eye, Yamato found the massive weapon mere inches from her face. There was no room left to dodge. Gritting her teeth, she closed her eyes and braced herself to counter the devastating blow.

But in that crucial instant, a blur of movement intervened. A pair of elegant legs sheathed in the glossy black of Armament Haki appeared between them. The newcomer delivered a powerful kick directly to Kaido's wrist, momentarily disrupting his attack.

Seizing this precious opportunity, Yamato ducked beneath the kanabo's path. Together with her timely savior, she leapt backward, putting distance between themselves and the Emperor of the Sea.

Sweat beading on her forehead, Yamato first nodded gratefully to Hancock, who had arrived at the perfect moment.

"Thank you," she breathed, before turning her attention back to Kaido, eyes blazing with newfound understanding and rage.

"You bastard!" she shouted, voice trembling with emotion. "You truly intend to kill me, don't you?!"

Kaido massaged his kicked wrist, his gaze shifting between the two women now standing side by side. After hearing Yamato's accusation, he made no attempt to deny it.

"Yamato," he replied, his voice eerily calm and deliberate. "I'm done playing family with you."

The words fell heavy in the air between them. "Since you refuse to follow my path, you are of no use to the Beast Pirates or to me." His eyes narrowed dangerously. "What's more, you now wear the uniform of the Marines. You should understand better than anyone the blood-soaked history between Marines and pirates."

Listening to Kaido's cold declaration, Yamato tightened her grip on her kanabo until her knuckles turned white.

Whatever lingering hope she might have harbored—that somewhere deep inside this monster existed a father who cared for her—evaporated in that moment.

"I should have known long ago," she said, voice thick with emotion. "You are nothing but an inhuman monster. You always have been... and you always will be!"

Yamato's anguished roar echoed across the battlefield as memories of her childhood flooded back. She remembered a kind-hearted Beast Pirate who had secretly brought her food when Kaido had ordered her starved as punishment. The man, whose name she never even learned, had shown her simple kindnesses—smuggling meals, blankets, even a few moments of companionship to the lonely child.

But one day, Yamato discovered that this nameless pirate had been publicly executed on Kaido's orders. His crime? Showing compassion to the Emperor's unwanted daughter.

It wasn't just him. Almost everyone who had shown her kindness over the years had met a terrible fate. Those she might have called friends were either killed by Kaido or driven away by fear of his wrath, leaving her utterly alone.

Was it really Kozuki Oden she admired so deeply? Or was it what he represented—freedom to adventure, to forge meaningful bonds, to escape the cage her so-called father had constructed around her life?

And now, at last, she had succeeded. Standing alongside Luffy and his allies, she was finally living the life she had always dreamed of. She had made peace with her past and honored the memory of those who had suffered because of their connection to her.

"KAIDO!" The name tore from her throat like a battle cry.

With determined strides, Yamato advanced toward her father. The kanabo clutched in her hands began to respond to her heightened emotional state, vibrating subtly and emitting a low, resonant hum.

Hancock, who had initially moved to stop her reckless charge, froze in her tracks. Her eyes widened as she witnessed crimson and obsidian lightning suddenly crackling along the length of Yamato's weapon.

"That's—!" Hancock gasped in disbelief. "Advanced Conqueror's Haki?!"

Not only her, but Luffy and the others watching from a distance also witnessed this phenomenon. Astonishment spread across their faces as they realized Yamato had unlocked the ability to infuse her attacks with Conqueror's Haki—one of the rarest and most powerful techniques in the world.

Among the three in their makeshift family who possessed the King's disposition—Luffy, Hancock, and Yamato—she was the first to manifest this advanced application spontaneously in battle.

"This is getting interesting," Luffy remarked, his expression shifting to one of strategic assessment. He turned to the others nearby. "Koala, Gion, you two should join in now. Help Yamato hold her ground a while longer so she can acclimate to this new power."

Luffy had originally planned to let Yamato and Kaido exchange just a few blows—enough for her to vent her anger before they proceeded with their actual mission. But this unexpected development changed things. She needed time to familiarize herself with this newly awakened ability, and facing Kaido alone would be too dangerous while she was still learning to control it.

"W-what? I—I'm not ready yet!" Koala stammered, her face paling at the prospect of confronting the World's Strongest Creature.

Chapter 495: Awakened Resolve - Koala's Explosive Transformation!

Koala hesitated, her feet seemingly rooted to the ground. Doubt clouded her mind as she considered Luffy's request. Would she—a relative rookie who had only recently mastered both colors of Haki—truly survive a direct confrontation with the Emperor known as the World's Strongest Creature?

Vice Admiral Gion noticed her hesitation and gave her an impatient pat on the back, her voice stern with a hint of challenge.

"Move it, rookie! If you don't join the group effort now, you'll end up facing Kaido one-on-one later."

Without waiting for a response, Gion unsheathed her famous blade, Konpira, from her waist. The legendary sword gleamed in the sunlight as she charged into the battlefield with confident strides.

"H-hey, wait!" Koala called after her. "I'm coming too!"

After quickly weighing her options—fighting Kaido alongside allies versus potentially facing him alone later—Koala made her decision. Group battle was undoubtedly the wiser choice.

However, she still recognized her limitations in direct close-quarters combat against someone of Kaido's caliber. Her Fishman Karate, while formidable against most opponents, might not be enough against an Emperor's overwhelming physical might.

Making a split-second tactical decision, Koala focused her energy and began her transformation. Her body glowed with an ethereal light as she shifted into her human-beast form—the manifestation of her Pink Dragon Mythical Zoan Devil Fruit. While similar in base structure to Kaido's Azure Dragon form, hers was distinctly more feminine in appearance, with rose-colored scales that shimmered like cherry blossoms in spring.

After completing her transformation, Koala maneuvered to position herself strategically. Finding an angle where Kaido was distracted by his engagement with Gion, she inhaled deeply and released a concentrated breath of scorching flame.

"Hmm?"

Sensing the heat wave approaching from behind, Kaido abandoned his match with Gion and delivered a powerful punch toward the Vice Admiral. Gion raised her sword in defense, but the sheer force behind Kaido's blow still sent her sliding back several steps.

The Emperor turned to face this new threat, his eyes narrowing at the familiar technique directed his way. Without hesitation, Kaido opened his massive jaws, gathered his strength, and unleashed his own breath attack—a devastatingly powerful stream of concentrated flame that dwarfed Koala's attempt in both size and intensity.

"Eek! That's too much!" Koala yelped, quickly abandoning her attack and diving sideways to avoid being engulfed by Kaido's overwhelming counter.

As she dodged, her full transformed state became visible to Kaido for the first time. Almost instantly, his eyes widened with intrigue.

"Well, well, little girl," he rumbled, genuine curiosity in his voice. "What's that ability you possess? The Pink Dragon Fruit?"

He paused, reconsidering his assumption. "No, that can't be right. There shouldn't be two identical Devil Fruits existing simultaneously in this world."

His eyes gleamed with increasing interest as he studied her form more carefully. "Your coloration differs from mine... could it be a sister fruit to my Azure Dragon? A complementary power?"

A wide, unsettling grin spread across his face. "Oh ho ho ho! This becomes more fascinating by the moment!"

Kaido's self-directed musings ended with boisterous laughter that echoed across the battlefield. The sound sent chills down Koala's spine, causing her to tremble involuntarily like a cornered animal. Just now, she had felt a primal fear—the terrifying sensation of being marked as prey by an apex predator.

There's no doubt about it, she thought with growing panic. He's fixated on my Devil Fruit. He wants to see its full capabilities...

Koala's thoughts raced frantically. What should I do? What should I do?! I've barely joined the fight and already I'm being targeted by the final boss! Hancock-san! Gion-san! Yamato! Someone help me!

But contrary to her internal pleas, the situation was developing more favorably than she realized. While Kaido stood laughing and momentarily distracted by his discovery, the three female warriors had already prepared their coordinated assault.

Seeing that Kaido had foolishly turned his back to her, Vice Admiral Gion's eyes flashed with fierce determination. She gripped Konpira's hilt tightly with both hands, dropped into a low stance to gather momentum, and adjusted her grip so the blade was positioned horizontally, aimed directly at Kaido's exposed back.

"Ittoryu: RANKAKYU!" she shouted, her voice cutting through the air like her blade soon would.

As power accumulated in her limbs, Gion pushed off with explosive force, launching herself forward with blinding speed.

Though Kaido's attention had been captured by Koala's transformation, his battle instincts remained razor-sharp. Sensing the imminent danger approaching from behind, he snapped back to awareness and swiftly pivoted, raising his kanabo to intercept Gion's strike.

Simultaneously, he began gathering energy in his throat, preparing to unleash another devastating breath attack at the first opportunity.

But someone moved even faster than the Emperor.

Just as Kaido's fiery breath began to take form, Yamato's icy counterattack struck first. Her "Namuji Hyoga" hit him square in the face, the sudden temperature shock disrupting his technique before it could fully manifest.

Capitalizing on this opening, Hancock followed with perfect timing. She launched herself into the air with graceful precision, her long legs—now coated in the glossy black of Armament Haki—connecting solidly with Kaido's midsection in a devastating kick.

More dangerous than the physical impact was the special property imbued in her attack. Where her leg made contact with Kaido's body, the skin began to show the telltale signs of petrification—slowly turning to stone from her Mero Mero no Mi ability.

Witnessing the three women's coordinated assault successfully delay Kaido, Koala couldn't help but exhale in relief. But that moment of respite quickly gave way to shame as she reflected on her own performance.

I allowed myself to be intimidated by Kaido's mere presence, she thought, her face flushing with embarrassment. What kind of revolutionary am I? If I cower before Kaido, how can I ever stand alongside Luffy against the World Government?

The reality of her situation struck her forcefully. Luffy had brought only four combatants on this mission apart from the observers Mansherry and Viola. Now Yamato, Hancock, and Gion were engaging Kaido head-on, holding their own through teamwork and coordination.

Meanwhile, she had contributed nothing but hesitation and fear.

I possess the same class of Devil Fruit as Kaido—a Mythical Zoan Fish-Fish Fruit, she realized. So why is he so overwhelmingly powerful while I shrink away at the first sign of danger?

In that moment of clarity, something profound shifted within Koala's mind and heart. She was no longer the helpless slave child of the Celestial Dragons, bearing their mark and living in constant terror.

Nor was she merely a low-ranking Revolutionary soldier, relegated to support roles while others took the spotlight.

She was Koala—user of a rare and powerful Mythical Zoan Devil Fruit, Deputy Director of Intelligence for Marine Branch G66, and a woman destined to stand beside the future Pirate King!

"KAIDO!" she roared, her voice carrying a newfound strength that surprised even herself. "Stop acting so high and mighty! I'll show you just what I'm capable of!"

The four paused their skirmish momentarily, all turning with varying expressions of surprise to witness Koala's transformation—not just physical, but spiritual. The timid rookie was gone, replaced by a warrior with blazing determination in her eyes as she strode purposefully toward them.

Though Kaido couldn't understand what had triggered this sudden change in the young woman, he couldn't help but smile with genuine excitement. Brushing off the attacks from the three women as if they were merely an inconvenience, he hefted his massive kanabo onto his shoulder, his eyes locked on Koala's approaching form.

"Wororororo~" his distinctive laugh echoed across the battlefield. "That's the spirit! All that confidence... now let's see if you have the strength to back it up!"

His eyes gleamed with dangerous anticipation. "Come then, little dragon. Let me test your limits!"
