He doesn’t break the rules. He replaces them. David awakens a soul-harvesting ability that lets him steal Devil Fruit powers from the dead. Pirates fear him. Marines hate him. The world misunderstands him. But David isn’t here to play hero or villain. He kills Blackbeard and steals his identity. He captures Ace and triggers Marineford EARLY. He infiltrates Impel Down, topples Warlords, rewrites destinies, and reshapes the One Piece timeline with every step. Every soul he takes becomes another weapon. Every enemy he kills becomes another power. Every choice he makes pushes the world further off its rails. This is the story of the man the world will remember not as a pirate, not as a Marine… but as the Reaper who changed the age itself.

One day, I transmigrated into the world of One Piece. Kai became the son of Monkey D. Dragon, with a grandfather named Monkey D. Garp, and a goofy, airheaded younger brother named Luffy. Fortunately, the Ghost Back System activated! Ghost Back Completion: 10% — Training efficiency increased by 100 times! Ghost Back Completion: 20% — Training efficiency increased by 1,000 times! ... One day, when Kai’s Ghost Back had fully awakened, he appeared before Luffy, who was shouting about wanting to go to sea— and scared Luffy into tears on the spot. Luffy: “Pirates on the sea… are they all monsters like my brother? I don’t want to go to sea anymore!” Garp: “Dragon and Luffy, those two brats, with their scrawny arms and legs, I always suspected they weren’t my real son and grandson. Now Kai—he’s the one who truly looks like my grandson!” Sengoku: “The strongest creature on land, sea, and air is Kaido? No—it’s Kai!” Want additional chapter? https://www.patreon.com/ZeusOp

“Only Haki can stand above everything else.” This was the supreme creed of the Great Route’s gold-medal lecturer, “Hundred Beasts” Kaido, a truth worshipped by countless people. But Roy did not agree. “Then let me ask you this... If there were an ability user who could analyze and collect all Devil Fruit powers, and who was unaffected by Seastone or seawater… couldn’t he rely on Devil Fruits alone to reach the pinnacle of this sea?” To prove his belief, Roy took action. Many years later. The Red Line, the Holy Land Mary Geoise, was engulfed in raging flames. Above Pangaea Castle, the one responsible stood calmly in the sky. A pristine white Marine cloak fluttered violently in the wind. “Are you going to make an enemy of the world?” The World Nobles demanded. Roy only bared his teeth in a grin. “Wasn’t I already an enemy of the world?” He smiled. Those who followed him stepped forward from behind. The figures at the front caused the entire scene to fall into dead silence. Everyone recognized them. They were the terrifying powerhouses who had risen suddenly to fame across the seas in recent years. Among them were assassins, revolutionaries, pirates, merchants, doctors… Without exception, they were all top-tier ability users, and all belonged to the same organization. It was said that this organization had a mysterious leader, the most dangerous criminal on the seas today. And now, the truth was obvious. “Y-You are…” The new legend of the Marines. The most dangerous criminal on the sea. From the very beginning, the two had always been the same person. His name was... Roy·Amos.

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.

After Marineford, the world thinks Whitebeard’s quake power died with him. It didn’t. In the underground of Dressrosa, a disposable gladiator is executed in the colosseum—then opens his eyes inside his own corpse as a cold voice whispers: “Ajin System… activated.” Now an immortal anomaly, every death lets him revive, and every battle lets his invisible shadow soldiers devour pirates, Haki, and even Devil Fruit users.
