I Am Kaido
Grand Line, New World.
In the perilous seas near Wano Country, deep within the territory ruled by the Yonko, there existed an isolated sky-piercing island wrapped in dark thunderclouds.
This island had stood for countless years. From afar, it looked like a colossal horned skull resting above the ocean a land reminiscent of the legendary island fortress Onigashima. Gigantic ancient trees filled the island, the shortest towering over a hundred meters tall, while the tallest stretched thousands of meters into the storm-filled heavens. These trees constantly absorbed lightning from the surrounding thunderclouds, nurturing the violent ecosystem of the island. Within this dense, pitch-black forest lived countless terrifying Beasts creatures enormous in size, with iron-like hides and savage instincts. The brutal environment had shaped them into relentless predators that lived only to slaughter and survive.
Because of this, even the isolated samurai nation of Wano, a land that feared neither pirates nor Marines, avoided venturing into this cursed place.
However, in the past three months, this island once filled only with thunder and the roars of monsters had begun to emit strange, earth-shaking sounds at irregular intervals.
Just like now…
"Wororororo…!!!"
Along with it came violent tremors that spread across the entire island.
"Boom… Boom… Boom…!!!"
The ferocious Beasts instinctively reacted, fleeing in panic in every direction as if facing a natural disaster.
Although the sky was perpetually dark, flashes of lightning occasionally illuminated the island. In those brief moments of light, one could see a massive shadow tearing through the ancient forest.
It was a colossal azure dragon.
A gigantic Eastern dragon stretching over a thousand meters, its serpentine body coiling around the entire island. Azure scales shimmered under the lightning, and its massive horns split the clouds. It rampaged with unstoppable force, crushing mountains and forests alike. Towering trees shattered like twigs, stone cliffs crumbled instantly, and even lightning bolts striking its body failed to slow it down in the slightest.
After a long time, as if finally venting its strength, the enormous dragon gradually slowed.
It raised its massive head toward the distant dark sea. Its vertical pupils glowed like burning lanterns, filled with boundless excitement. Slowly, its jaws opened, and blazing flames gathered deep within its throat.
"Boro Breath…!!!"
A scorching beam of destructive fire tore across the sky, stretching several kilometers over the ocean. The night lit up like day, and the sea below instantly boiled, steam roaring into the heavens.
Moments later, the flames faded.
The colossal dragon body began shrinking rapidly, its scales receding as it transformed into a gigantic humanoid figure.
A towering man stood there, over seven meters tall, with a body like forged steel. His muscles bulged like coiled iron cables, and two massive horns curved from his head. Long black hair flowed down his back like a storm cloud. In his hand rested a gigantic kanabo a spiked iron club capable of crushing mountains.
With a casual swing of the kanabo, black lightning and red sparks burst into existence, crackling violently the unmistakable manifestation of Haoshoku and Busoshoku Haki intertwining.
"Thunder Bagua…!!!"
"Ragnaraku…!!!"
"Gundari: Dragon Swarm…!!!"
"Roaring Thunder Bagua…!!!"
"Great Full Thunder Bagua…!!!"
Each strike shook the entire island. The sky split, thunder howled, and shockwaves tore across the forest like tidal waves. Even the clouds themselves seemed ready to collapse.
If he had unleashed his full power without restraint, the island would have been obliterated long ago. But even while holding back, the devastation resembled a calamity on the level of a Buster Call or a natural disaster. The terrifying Beasts could only collapse onto the ground, trembling, not daring to move an inch.
After nearly three hours of destruction, silence finally returned.
The massive figure dropped heavily onto the ruined earth. He grabbed a giant sake gourd nearby and gulped it down in huge mouthfuls.
Under the gourd, a crumpled bounty poster was partially visible.
The face on it was unmistakable the man who would one day shake the world.
Monkey D. Luffy.
A rising pirate from the Worst Generation, whose bounty was steadily climbing through the New World.
At that moment, a wild, ecstatic laugh echoed once more.
"Worororororo…!!! This power is incredible… Truly incredible… So this is the strength of a Yonko… the body of Kaido the King of the Beasts… the so-called Strongest Creature in the World."
His voice trembled with excitement.
"This indestructible body… this overwhelming vitality… the power of the Mythical Zoan the Fish-Fish Fruit, Model: Azure Dragon… and this monstrous Haki… It's absurdly powerful…!!!"
If any member of the Beasts Pirates were present to hear this, they would be utterly horrified.
Because they would immediately realize something impossible.
The man standing here was no longer the same Kaido they once followed.
Inside the body of the Emperor of the Sea now lived another soul.
A transmigrator from another world.
A man once known on Earth as Takamagahara.
And now
He was Kaido.
