Reborn amid the salt, blood, and storm of the Iron Islands, a foreign soul awakens inside the body of Euron “Crow’s Eye” Greyjoy, long before madness and ruin claim his name. This time, however, Euron is no mere reaver driven by cruelty and chaos. He carries with him the Pirate King System, an otherworldly power born of legend and conquest. With his left hand, he unleashes Conqueror’s Haki, a kingly will capable of crushing weaker minds, bending lords to their knees, and tearing apart the intricate political webs of Westeros. With his right hand, he commands the Mastery of the Seas, ruling waves, storms, and fleets as if the oceans themselves answer his call—turning naval warfare into absolute dominion. This Euron knows the future. He knows the betrayals, the deaths, and the fate awaiting House Greyjoy. And he refuses to let his family be consumed by tragedy once more. As the Ironborn rise under a banner of discipline instead of madness, their ancient creed—“What is dead may never die”—takes on terrifying new meaning. From the Iron Islands to King’s Landing, from frozen northern waters to burning southern seas, Westeros is forced to face a truth it has never known: A true Pirate King has arrived. Balancing ambition with loyalty, brutality with vision, Euron sails not just to conquer—but to rule. When the waves finally break against the shores of the Seven Kingdoms, only one question will remain: Will the Iron Throne bend… or be drowned beneath the tide?

Reborn into the world of Naruto, I became the elder brother of Hatake Kakashi. But I did not arrive empty-handed—a mysterious system, granting me the power of a Devil Fruit from another world, has been embedded within my body. With this power, I will stride across the battlefields of the shinobi world, shatter the limits of human strength, and carve the name Hatake Yusuke into history as the strongest existence of this era. Without the desire for power, wealth, or women, I have only one goal: To become the strongest in the entire ninja world. — — — This story follows the main plot of Naruto, but with the addition of a unique system. The protagonist walks the path of a semi-invincible existence, and is not the typical harem-seeking character.

In the swirling currents of time and fate, one soul was cast into a world it was never meant to be in. Karl D. Sephiroth-a name unknown to history, yet one that would soon shake the very foundations of the world. He is not a pirate. Nor a marine. He is a time traveler-an outsider who gained the Batto Batto no Mi Devil Fruit at the wrong time... and in the wrong place. With a power that blurs the line between life and death, Sephiroth seeks only one thing: A peaceful and beautiful life in this chaotic and disordered world of One Piece. But this world does not allow anyone to live in peace so easily. Position? Justice and evil? "The winner is the king... and the loser is just a bandit." In these seas, it is not principles that shape history-but power. Justice and evil are mere concepts... privileges that belong to the victors. And Sephiroth? He has no problem being called a hero, as long as he is the one who wins. Those who have witnessed his existence say: Boa Hancock, Pirate Empress: "Sephiroth... as long as you wish, I will do anything for you!" Kozuki Hiyori, Princess of Wano: "For the sake of our master, Brother Momonosuke... I beg you, die!" Sengoku, the Legendary Admiral: "I could never tell if Sephiroth is a righteous man... or not." Monkey D. Dragon, Leader of the Revolutionaries: "Friend... could you help me revise the revolutionary program of this world?" Sora Cyborg, Supreme Commander of the World Government: "This man... Sephiroth... he is truly insufferable!" And so... begins the story of a man who refuses to follow the tide. A victor who rewrites the meaning of 'justice' with his own hands.

After waking from his slumber, Yumesaki realizes that he has somehow gained the ability to travel across various worlds. ​ As an ordinary man at heart, he has no taste for mindless conflict or slaughter.

In the era when Navy hero Garp is chasing Pirate King Roger across the Grand Line, a young man awakens in a fragile human body that simply refuses to die. Bullets to the head, cannon blasts to the chest, blades across his throat, drowning seas, and raging flames can destroy his flesh, but they can never claim his life. After countless brutal “deaths,” he realizes that mere immortality is not enough in a world ruled by monsters like Rocks, Roger, and Whitebeard.​ Determined to stop being a passive punching bag, he chooses the most domineering path in the One Piece world: to first max out his Conqueror’s Haki and then overwhelm the era itself. From the shadows of that legendary time, he crashes into the mainstream of history, clashing with Marines, pirates, and royalty, carving his name into the seas as the undying king whose will no one can suppress.

"I raised the Hero of the Marines, mentored the Fleet Admiral, and shaped the era itself. Now, at a hundred years old... my journey is finally beginning." Transmigrating into the world of One Piece with a personal System, Rowan expected to reach the pinnacle of power in record time. But fate had other plans—the System glitched, remaining stuck in a loading loop for decades. Rowan didn't wait around for a miracle. Using his knowledge of the future, he carved his own path. He adopted a rowdy brat named Monkey D. Garp, forged a life-and-death brotherhood with future Commander-in-Chief Sora, and disciplined a generation of legends including Sengoku, Zephyr, and Tsuru. A century has passed. While training his great-grandson, Luffy, Rowan finally feels the heavy toll of time on his bones. Just as he prepares to close his eyes and accept the end of his long watch, a familiar sound echoes in his mind: [System Loading: 100%... Activation Successful.] [First Mission: Become a Marine Admiral.] Looking at the prompt, the century-old legend can only scoff: "Are you kidding me? I’ve been the backbone of the Navy for a hundred years, and now you want me to start a career as an Admiral?!" The Old Guard has returned. The pirates think the era belongs to them—until they meet the man who raised their greatest enemies.

Traveling through the world of One Piece, I unexpectedly became Roger's younger brother. It's hard to imagine that Roger, who is over fifty years old, could have a teenage brother. But while my brother became the Pirate King, I was utterly talentless. Fortunately, at the age of sixteen, I discovered I had a possession system. By possessing Ip Man, I gained the mindset of a martial arts grandmaster. By possessing Gai Nie, I acquired the art of the Hundred-Step Flying Sword. By possessing Li Xiaoyao, I mastered the Shushan Sword Techniques. Think that's all? You're wrong! Pain, Itachi, Ichigo Kurosaki—if I have money, I can possess the spirit of anyone. This is a world where money can make ghosts do your bidding!

Once in the world of Naruto, I established the Kingdom of Qin, standing alongside the Five Great Nations and pioneering a civilization of ninjutsu. Once in the world of One Piece, I conquered the Grand Line, challenged the Four Emperors, and founded a civilization of Devil Fruits. Once in the world of Chinese Paladin, I ruled over Shushan, wielding a sword with the South Mountain as its hilt and the North Sea as its blade, slashing through all beings and establishing a civilization of Sword Immortals. Once in the world of Bleach, I crossed the boundaries of life and death, transforming into the King of the Underworld and forging an eternal divine kingdom. Once in the world of Journey to the West, I overturned the Five Elements Mountain, stood shoulder-to-shoulder with the Great Sage, and led armies of millions to claim dominion in the West. Once in a world of science fiction, I piloted spacecraft through the cosmos, witnessing the splendor of countless worlds. Once in Perfect World, Tomb of the Gods, and Coiling Dragon, I sat among the kings of various realms, coldly dividing resources and clashing for supremacy. Gathering the myriad worlds, fusing their civilizations, and creating the ultimate divine kingdom. This kingdom spans infinite worlds. Billions of beings serve as the king's soldiers, infinite domains form the king's garden, and countless civilizations become the foundation of the king's strength! This is The King’s World!
