With cold determination and overwhelming dominance, Shinji crushes pirates, rivals, and even legends of the sea. His justice is not gentle—it is absolute. Garp: “Kid, let’s see how far you can go… and how long your fists can endure!” Sengoku: “I support Shinji to become the Marshal of the New Navy Headquarters!” Sakazuki: “You may have defeated me… but will your justice prevail?” Kong: “I’ve given you this seat. Tell me… can you hold onto it?” Dragon: “Your ambition is too great. You might become the next ruler of the world.” Blackbeard: “Damn it… why won’t you die?!” Shanks: “That level of Haki… I’d call it the strongest.” Luffy: “Navy King?! I’m gonna surpass you!” The Five Elders: “Kneel… before our king!” … And when Im finally rises from the Empty Throne— The boy who once struggled to survive has already become a king.

Everything has a price. What are you willing to pay?" ​Kai was a "Zero-Rank" nobody, destined to die in a dark spirit mine. But fate had other plans. Reborn in the legendary Loguetown on the day of the Pirate King’s execution, Kai awakens a power that defies the laws of the sea: The Universal Trading System. ​In a world ruled by Devil Fruits, Haki, and massive Pirate Crews, Kai doesn't need to train for decades. He only needs to Trade. ​A rusted sword? Trade it for Soul Coins. ​A Marine’s secret? Trade it for Agility Boosts. ​A Devil Fruit? Trade it for Infinite Evolution. ​While Luffy seeks freedom and Zoro seeks strength, Kai seeks the ultimate deal. He isn't just a pirate or a marine. He is the Merchant of Fate, and the Grand Line is his marketplace. ​"You call it a miracle? I call it a fair trade

Thirty-eight years ago, the God Valley Incident was brought to an end by the World Government, marking the curtain fall of the Rocks Pirates. However, the Celestial Dragons, lofty as they were, failed to realize that an even more terrifying monster had begun to move. Soon, his enemies would discover that no matter how many times they severed his head, pierced his body, or reduced him to ashes—none of it could truly kill him. Only when blood flooded the vacant throne did they finally understand who their opponent truly was. The man who pushed the Bat-Bat Fruit, Mythical Zoan, Model: Vampire, to an unprecedented level. The man whose mastery over all three colors of Haki reached its absolute peak. His name—Nereus. Lord of the Deep Seas, Immortal King, the Liberator… His name has never ceased to echo across the seas.

"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.

Unlike the original protagonist, I gained an ability that strengthens my Haki. Anyway, let's try to live as freely as possible. I am writing this so that even those who don't know One Piece can fully understand the story.

In the Great Pirate Era, countless people rushed to the sea. The person who obtained Arceus’ power arrived in this world as the new Arceus and got in touch with the Lunarian race. Based on the reality that everything can be Mythical Zoan, the current him can also be called Mythical Zoan user. Whether it is One Piece or Pirate King, it has nothing to do with him, all he wants to do is to retrieve the lost plates first. During this process, he formed an alliance with Beasts Pirates, a famous pirate crew in the New World, and Mr. Kaido got his coveted Mythical Zoan Army. When Pteranodon becomes Aerodactyl, when Brachiosaurus becomes Tropius, the combination of Pokémon and devil fruit powers will bring a whole new change to the world…. Lunarian’s glory will surely reappear. *This is a fan translated novel by me ****Please support on pat*eon for extra chapters https://www.pat*eon.com/dmtranslations

But when the System awakens inside its walls, reality itself begins to twist. Akai, a new prisoner cast into the depths of despair, discovers that the same mysterious power that once chose Sung Jin-Woo now chooses him. Surrounded by endless darkness, monstrous prisoners, and guards more terrifying than beasts, Akai realizes that survival means more than just escaping chains—it means ascending. Each floor of Impel Down becomes a dungeon, every warden a raid boss, and every prisoner a potential shadow to command. As Akai learns to wield the terrifying might of the Shadow Monarch, the prison spirals into chaos. But the World Government does not sit idle… and soon, legends of the sea—pirates, admirals, and even the Warlords—are drawn into a battle that could shake the balance of the world itself. What begins as one man’s fight for freedom transforms into the rise of a new king, born not of the sea, but of shadows. ____________________ Join Me in My Patreon For Extra Chaptes : Patreon.com/Doflamingo4

Transmigrating into the world of One Piece, a man named Raleigh becomes a Marine... but with a twist. He's acquired a "Slacking Off System" that rewards him for doing the absolute minimum. Catching pirates? It's too dangerous for a measly salary. He's seen the example: men like Akainu fight the hardest battles, suffer the worst injuries, and earn nothing but scorn from his allies like Sengoku and Garp. Raleigh's path is clear. [Slept during pirate-hunting duty, Slacking Value +100] [Enjoyed a massage from Hancock during work hours, Slacking Value +200]. The Great Pirate Era, the rivalry of the Yonko, the position of Fleet Admiral—to Raleigh, these are all meaningless. "What's the use of all this?" he'd say. "It's not even as good as the imported grapes Hancock feeds me." Both Marines and pirates dismissed him as a harmless, lazy fool. They were all wrong. One day, Raleigh strolls up to the holy land of Mary Geoise, kicks open the gates, and addresses Im in the Pangaea Castle: "Hey, isn't it about time I had a turn on that throne?"

I transmigrated into the world of One Piece. My new identity? Kaido, the "Strongest Creature,"… but I’ve arrived thirty-one years too early. With power and potential far beyond the original, and all this time to prepare, the world's balance is a joke waiting to be shattered. The Marines? A future nuisance. The Yonko? Not even a concept yet. The Celestial Dragons lounging on their holy land? They’re living on borrowed time. The Empty Throne has waited for a true king for centuries. I am no mere pirate seeking freedom or treasure. I am the Beast Sovereign, and I will tear down this rotten world to build my empire in its ashes. The age of gods and dragons ends now. My reign begins.

Monkey D. Luffy lived a life no one else could. He sailed every sea. He fought every monster. He lost people he loved and kept moving anyway. He stood at the top of the world, found the One Piece, and became the King of Pirates. Then he woke up as a ten-year-old child in a world with no ocean. Terra Fracta. A world shattered two hundred years ago — where the sky is broken, the ground floats in darkness, and something called the Void waits beneath everything for someone to fall. No crew. No Devil Fruit. No way home. But a Voice speaks to him now. It gives him Quests. It gives him power. And it keeps hinting at one impossible truth: there is a road back to his world — and it runs straight through the most dangerous place in this one. Luffy has been the weakest person in the room before. He knows how that story ends. _________________ Author: NITROGENO ( anyway it's me ) ___________________ Note: This story follows Luffy, with full memory of his life in One Piece, dropped into a completely original Post-Apocalyptic world with its own power system, factions, and history. If you are looking for a story where the hero starts from zero and earns every step. this is it. No instant power. No easy wins. Just Luffy being Luffy in a world that was not built for him.

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.

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?

When a modern man named Ray opens his eyes in the world of One Piece, he's gifted a cheat system of legendary proportions: the Sesshomaru Template. Reborn with the silver hair, demonic powers, and cold demeanor of the powerful Dog Demon, Ray begins a new life not as a hero, but as an aloof conqueror. To increase his fusion with the template and unlock devastating abilities like the Azure Dragon Strike, Ray must immerse himself in the world's pivotal events. He finds the perfect path by joining the fledgling Straw Hat Pirates, placing himself at the epicenter of the chaos that follows Monkey D. Luffy. Raw in the review.
