In the New World, a dangerous stretch of the Grand Line, lay an ancient island near the shores of Wano Country. Dark clouds permanently covered the sky above it, and it had existed for a time beyond memory. The island itself looked strange, like a giant egg wearing a black cap. Colossal trees grew all over it; the smallest were a hundred meters tall, while the tallest soared thousands of meters into the clouds. These giant trees seemed to draw power from the lightning that flashed in the sky, feeding the entire island.
Deep within the dark forest, terrifying Beasts made their homes. They were enormous creatures with thick hides, and the gloomy environment had made them experts at hunting and killing. They were incredibly ferocious. Because of this, even the powerful samurai from Wano Country stayed far away from the island.
But for the past three months, the sounds of thunder and the roars of Beasts had been joined by a strange new noise. It was happening again right now.
"Worororo…"
A deep, booming laugh echoed across the land, followed by immense tremors that shook the entire island.
Boom… Boom… Boom…
The ferocious Beasts reacted with pure instinct, scattering in every direction to escape the source of the noise. In the darkness, it was hard to see anything clearly. But whenever lightning flashed, it would briefly reveal a monstrous shape moving through the ancient forest.
It was a colossal azure dragon. It was over a thousand meters long and nearly a hundred meters wide, its massive body coiling around the island. It moved with unstoppable force, destroying everything in its path. Thick trees, hard rocks, and even the lightning striking down from the sky couldn't slow it down.
After a long time, the dragon seemed to have vented its energy and slowly came to a stop. It raised its enormous head high, its terrifying, lantern-like eyes filled with excitement. It stared out at the dark sea in the distance and opened its massive mouth. Scorching flames gathered within its jaws.
Boom!
A beam of fire, a Heat Breath several kilometers long, shot out over the sea. It lit up the entire world for a moment and made the ocean water boil and steam.
A minute later, the flames died down. The colossal dragon's body slowly began to shrink, transforming into a seven-meter-tall man with a giant, muscular body. In his hand, he held a massive black kanabo.
He swung the kanabo, and terrifying power mixed with streaks of black and red lightning erupted with each attack, shaking the very foundations of the island.
"Thunder Bagua!"
"Descent of Three Worlds: Ragnarok!"
"Vajra: Arrow!"
"Drunkard's Thunder Bagua: Ragnarok!"
"Kundali: Dragon Gaze!"
"Roaring Thunder Bagua!"
"Great Full Thunder Bagua!"
If he hadn't been holding back most of his power and Haki, the entire island would have been destroyed long ago. Even so, his strength was like a natural disaster. The island looked as if it had been hit by a storm of immense power. The terrifying Beasts could only lie flat on the ground, completely frozen with fear.
After about three hours, the destruction finally stopped. The enormous man slumped onto the ruined ground, picked up a giant sake gourd, and began to drink from it. Beneath the gourd was a wanted poster: Monkey D. Luffy, Bounty: 30,000,000 Berries.
At the same time, a joyful laugh echoed once more.
"Worororo… This is amazing! Truly amazing! So this is the body of one of the Four Emperors of the New World. The body of Kaido, known as the King of the Beasts and the World's Strongest Creature. It doesn't matter if it's this indestructible physique, the power of the top-tier Mythical Zoan, the Fish-Fish Fruit, Model: Azure Dragon, or this unbelievably strong Haki… it's all incredible!"
If any of the Beasts Pirates were here, they would have been shocked to hear their Captain's words. They would never have guessed that their leader was no longer the original Kaido of the Beasts. Instead, he was a transmigrator from Earth named Gao Tianyuan.
Three months ago, Gao Tianyuan had been just an ordinary office worker. His life was a simple nine-to-five routine, so his only hobbies were watching anime, dramas, and reading novels online. Naturally, One Piece, one of the most famous shonen manga, was a series he followed closely.
However, ever since the story entered the Wano Country arc, Gao Tianyuan's love for One Piece had started to fade. The plot twists and character decisions felt strange to him. His affection for the main characters began to disappear, and he even started to feel some sympathy for Kaido, the main villain of the arc. But he knew that villains were always meant to be defeated by the hero, so he didn't think too much about the final outcome.
Then, three months ago, the One Piece anime released a new episode. It showed the Marine hero Koby single-handedly taking on the pirates at Honeycomb Island. After watching that, Gao Tianyuan felt completely disgusted. It was common in action-packed manga for new characters to become powerful, but it was rare to see it done in a way that made so many other great characters look weak and foolish.
It felt like Koby's existence turned many of the strong characters that the author, Oda, had created into complete jokes. The one who looked the most ridiculous was Zoro, one of the main characters. The comparison made you wonder if Zoro's years of hard work were just for show. Why did Zoro, who trained his whole life to become the world's greatest swordsman, struggle to defeat a weak opponent like Hachi at the start of his journey? Meanwhile, Koby, after only two years of training, was able to help Blackbeard defeat the great pirate Wang Zhi, become a Marine hero, help capture the Warlord Boa Hancock, and even shatter one of the Tyrant Kuma's arms with a single punch.
Gao Tianyuan started to understand why some villains in stories wanted to destroy the world. If you put yourself in their shoes and realized that all your hard work, pain, and sacrifice couldn't compete with a simple phrase like "200 times the effort" or the main character's special luck, you would also lose hope in the world.
He was so disgusted that, for the first time, he felt a deep dislike for the entire One Piece story. He even thought that if he were Kaido, he would have eliminated the Straw Hat crew the moment they set foot in Wano Country. Then, he would destroy the world. After all, if a world could be saved by a hero like that, it probably wouldn't change for the better anyway. It would be just like the worlds of Naruto and Boruto.
Of course, he knew this was just a silly thought. The author of One Piece was Oda, and he was just a simple reader. But he went to sleep with that thought in his mind.
When he woke up the next day, something incredible had happened. His wish had come true. He had really transmigrated into the world of One Piece and had become Kaido of the Beasts. After the initial excitement wore off, Gao Tianyuan finally understood the meaning of the old saying, "Be careful what you wish for."
