After transmigrating into the world of One Piece, Kane becomes the orphaned son of a Marine Rear Admiral—and awakens the mysterious Scumbag Justice System. The rules are simple: Break naval regulations. Gain strength. At the elite Marine training camp, the system activates immediately. [Ding! Host reprimanded by Head Instructor Zephyr for an improper uniform at the opening ceremony. Disciplinary Violation +1!] [Ding! “Eyewitness Coefficient x5” triggered. Total Violation Value x5!] [Ding! Points credited. Available for physical enhancement and skill enlightenment.] Kane understands the loophole. The more outrageous the violation, the greater the reward. He sets his sights on a new goal: become the true king of the Navy. The atmosphere of the training camp shifts overnight. “Kuzan, justice isn’t learned in textbooks. Come see the real world.” [Ding! Abducting a future admiral and sneaking out after curfew. Violation +500!] [Ding! Subversion Coefficient x10 applied!] “Sakazuki, absolute justice means eliminating evil before it grows.” With a single strike, Kane executes a pirate in front of him. [Ding! Ideological subversion of a future admiral detected. Violation +5000!] [Ding! Subversion Coefficient x50. Massive reward granted!] Years later, Kane stands at the pinnacle of the Marines. Behind him are three admirals whose paths have been completely rewritten. Before him, a system interface filled with endless digits. “System,” he says calmly, “spin the Cosmic Wheel.” “Let’s see if today is the day I awaken Conqueror’s Haki.”

Sebastian never truly lived. Confined to a hospital bed since childhood, his body too weak to walk. The only places he could truly go were the worlds inside stories, comics and manga, fantasy books, games, and legends he consumed endlessly. Then death came quietly, but instead of darkness, Sebastian opened his eyes before a Goddess who offered him a single wish. Any wish. And Sebastian only asked for one thing. To simply live once more, for real this time. The goddess was intrigued by the humility of his request, she revealed a truth most souls never hear: returning to the world he came from was never truly an option. Even if someone wished for it, there was no guarantee they would return to their own reality. When he opened his eyes again, he found himself reborn on The Continent, The World of The Witcher a brutal world of monsters, politics, and endless war and evils both lesser and greater. A violent incident shatters his new beginning and sends Sebastian to the fortress of the witchers: Kaer Morhen. Sebastian awakens a mysterious system… And the power of the Flame-Flame Fruit, granting him Intangibility and dominion over fire. In a land where monsters lurk in forests and humans often prove worse than beasts, Sebastian must learn to survive a world that devours the weak, and sometimes there are no good choices to make.

He reincarnated to the world of One Piece with the immortal abilities of the Silver King, the First King from the manga/anime series *K*. Although he becomes a pirate, his goal is not to become the Pirate King. His goal is simply to live freely on the high seas—it's that simple.

Through the Sky Screen’s broadcast, Kaito summons heroes from other worlds and wields strange tools to twist reality itself. With the system he embraces the art of deception—fabricating half-true, half-false futures that even the wisest cannot ignore. Pirates, Marines, and Celestial Dragons alike are forced to accept these visions, no matter how absurd, as if stripped of every defense. In this false future, Buggy the Clown emerges as a nightmare reborn. After twenty years of secret training, his Devil Fruit awakening is said to hold enough power to shatter the Red Line. Former Shichibukai rally to his banner as sworn brothers, and even the Marine’s legendary hero Garp is proclaimed slain at his hands. Behind the laughter hides a vast conspiracy, one that threatens to upend the balance of the world itself.

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.

In a world where genetic Quirks define a hero’s worth, Roronoa Zoro stands as a silent defiance against the status quo. Born Quirkless within the walls of a traditional dojo, he trades flashy innate powers for the grueling, rhythmic grind of the blade, pushing human limits through thousands of daily swings and unwavering discipline. As he sets his sights on the prestigious U.A. High alongside Midoriya’s generation, Zoro’s journey is a meticulous, slow-burn chronicle of sweat and steel, proving that a sharpened spirit and a master’s technique can cut through any biological advantage.

But I assure it is totally different fanfriction and you will enjoy it.] Also please visit my patreon for advance chapters along with arts and picture collection in manga style.
