"Wo ro ro ro ro, you sure talk big!"
Kaido seemed utterly enraged.
His bloodshot eyes flashed with murderous intent as he growled: "Blood Thirsty Drunk!!!"
With a ferocious expression, he swung his Kanabo once more.
His attack, wrapped in the power of Haki, tore through the air toward Luke.
A terrifying burst of force, like an unstoppable force, shattered the air like a lightning strike, hurtling toward Luke from a distance.
"I'll prove it to you right now!"
Luke's gaze remained indifferent.
Showing no sign of backing down, he countered with a strike of his own.
His fists, wrapped in an overwhelming Haki, blasted through the incoming shockwave, dispersing it entirely.
Whoosh!
At that moment, Kaido suddenly moved.
Faster than thunder, swifter than lightning.
He swung his massive Kanabo, its surface crackling with both Conqueror's Haki and Armament Haki.
The world's strongest creature on land, sea, and air was now going all out, launching a ferocious and rapid assault on Luke.
Boom!
Terrifying lightning streaked through the sky, compressed to its absolute limit.
"Lightning Hammered Ragnaraku!!"
Kaido roared, with an unparalleled speed, moving faster than the eye could follow; he charged toward Luke with devastating force.
But at the very last moment…
Whoosh!
Luke vanished into thin air in a ghostlike manner without warning.
"What?!"
Kaido's expression changed drastically.
But it was too late to pull back his attack.
The Kanabo, charged with earth-shattering lightning, tore through the atmosphere with unstoppable momentum.
It smashed forward with overwhelming power.
Boom!!
The atmosphere itself twisted from the sheer impact.
A massive shockwave erupted outward and blasted down onto the ocean below, causing an enormous explosion of seawater.
Splash!
Giant waves surged violently, crashing and rolling endlessly.
Buzz!
Strands of electricity flickered and danced, intensifying the activation of every muscle and cell in Kaido's body, maximizing his reaction speed.
However, under the full enhancement of his awakened Vampire Fruit, Luke's speed had already reached an incomprehensible level.
His reflexes, bolstered to supernatural heights, allowed him to evade Kaido's attack effortlessly.
His body blurred into an afterimage, moving at an almost supernatural velocity.
He was so fast, so unreal, that Kaido's eyes couldn't keep up.
Whoosh!
The air itself was torn apart.
Luke's form became utterly undetectable to the naked eye.
And to Kaido's growing horror, his advanced Observation Haki, usually sharp enough to glimpse the future, was completely unable to lock onto Luke's presence.
Even worse, a nearly imperceptible web of shadowy threads had already spread across the entire sky; it was so densely packed that it was impossible to count.
"Huff... Huff..."
Then, with a counterattack, a sudden, deafening boom ripped through the air.
Fierce and relentless, Luke's punches exploded from every direction, striking non-stop.
He gave Kaido no chance to breathe.
The sky was filled with his murderous figures; each image was lifelike, and each one launched an attack.
Bang! Bang! Bang!
Kaido, having just poured all his strength into his last strike, hadn't even had a moment to recover and was immediately bombarded by a flurry of overwhelming, Haki-infused punches crackling with black-and-red lightning.
"Gahhh!!!"
His face twisted in agony.
Blood sprayed from his mouth as he was sent hurtling backward.
The dragon scales that once seemed indestructible now failed to protect him.
Luke's Armament Haki bypassed them, invading his body directly and wreaking havoc from within.
His chest, back, and abdomen all caved in under the relentless blows.
His eyes rolled back, and he nearly lost consciousness.
But with an awakened Azure Dragon fruit, Kaido possessed monstrous endurance and regeneration.
Even against the overwhelming barrage he endured.
"Rising Dragon!!"
Covered in blood, Kaido let out a furious roar.
Grinding his teeth, he fought through the pain, swinging his Kanabo wildly in raw desperation, defending himself on pure instinct.
"Huff... Huff..."
But against Luke, who had activated Observation Killing and who had perfectly fused the Shadow-Shadow Fruit and Vampire Fruit into an unpredictable, nightmarish combination, Kaido was completely outmatched.
Even with his vast battle experience, he couldn't tell if Luke was teleporting or simply moving at such an unfathomable speed that it felt like teleportation.
Every time he tried to strike back, it was only an afterimage.
And then, the true horror dawned on him.
His stamina was draining away.
No, it wasn't just stamina.
His body was aging.
Luke was stealing his youth.
Bang! Bang! Bang!
Despite his desperate resistance, with his Observation Haki failing and his body weakening, Kaido could not fend off Luke's relentless storm of attacks.
One after another, brutal punches and devastating kicks crashed into him mercilessly.
Blood sprayed everywhere; his entire body was battered beyond recognition.
Like a ragdoll, he was flung across the sky.
Whoosh!
Luke pursued with lightning speed, then without mercy; his strikes were sharp and ruthless, each one designed to kill.
Boom!
Ahhhhhhh!!!
On a deserted island, a towering figure was violently thrown onto the ground.
The cracked earth trembled under the impact, sending dust flying into the air.
Covered in blood and barely recognizable, Kaido had long since lost consciousness.
Not only had he reverted to his human form, but his hair had turned completely white, and he now appeared aged and withered.
A decaying aura of death surrounded him, making for a horrifying sight.
"Tsk, tsk... I have to admit, the awakened power of the Azure Dragon fruit is impressively tough. Even after all that, you still won't die."
A tall, dark figure flashed across the scene.
Luke, still maintaining his special Human-Beast Form, landed firmly on the ground.
His massive wings shrank at an observable speed and soon disappeared completely.
He had returned to his original form.
Yes, this was no ordinary Human-Beast Form.
It was a specialized transformation developed by judges and the Germa science team, combining their research with SIQ technology.
Similar to the Rumble Ball, this special drug could forcibly alter a Devil Fruit user's transformation frequency, allowing them to attain an entirely new form, one that retained human characteristics.
It could also temporarily enhance and amplify the user's combat abilities.
This drug was even more potent than the Rumble Ball that Chopper had accidentally discovered.
It allowed the user to decide whether to retain the original features of their Beast Form.
