Tidebound: The Great Sea Adventure Kael’s life ended in a flash of despair, but death was not the end. Pulled into a strange, boundless ocean world by an ancient, whispering force, he awakens with a mysterious power—the Tide Binding, the ability to control and become one with water itself. Alone and unprepared, Kael must survive raging storms, monstrous sea creatures, and treacherous islands as he learns to harness his powers. Along the way, he meets allies like Lyra, a fearless sailor with secrets of her own, and discovers that the vast oceans hide not only danger, but treasures, mysteries, and challenges beyond imagination. Every island brings new adventures, every wave tests his courage, and every battle pushes him to grow. But Kael’s ultimate goal is more than survival—he seeks a way back home, a path through a world where the sea rules all, and where only the clever, the brave, and the Tidebound can endure. Tidebound: The Great Sea Adventure is a slow-burning, epic journey of exploration, danger, friendship, and discovery—a story for those who dream of adventure on the endless seas.

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.

After being transported to the world of Naruto, Ryuzen awakened the Strongest Inheritance System and obtained the legacy of the world’s greatest swordsman, “Hawk-Eye.” From that day forward, a swordsman was born whose blade skills far surpassed even the legendary White Fang. “In terms of swordsmanship, among all who have faced me… I, Madara, acknowledge you as the strongest. But tell me—how will someone who stands beyond the Kage withstand the power of the Six Paths Sage?” “The moment something is born, its end is already decided. All things must eventually fall… and so will you.”

Release schedule: At least 2 chapters per day - sometimes more, depending on the power stones received A modern soul is accidentally reborn into the One Piece world, gifted by a “mass-market system” with the legendary Rumble-Rumble Fruit — transforming him into the feared “Thunder God” Leno. But he seeks no throne, no war, no crown… only freedom. Starting in Cocoyasi Village, he raises Nami and Nojiko into fierce warriors, then gathers a dazzling crew of heroines — Kuina, Uta, Hancock, and more — each drawn to his charm, power, and unwavering devotion. Nami pouts, twirling his collar between her fingers: “Leno~… you said I’d be your only bride… so why’s my wedding ring still waiting while you collect more beauties?” Nojiko leans in with a sly smile, voice velvet-soft: “Darling… should I start setting extra plates at dinner… or extra pillows in your bed?” Kuina crosses her arms, eyes gleaming with challenge — and something warmer: “So you ‘tricked’ me onto your ship? Fine. But if I become the World’s Greatest Swordswoman… you owe me a kiss for every title I win.” Sailing aboard a luxurious vessel flying the Adventurer’s flag, Leno turns world-shaking chaos into the backdrop for laughter, love, and lightning. His mission? Simple — empower his girls, protect what matters, and live unchained… with thunder in his hands, and a sea of beauty utterly, playfully, passionately devoted to him. 50+ Chapters: patreon.com/Hard_Worker

I am Blake, and I run a small stall in Foosha Village, working part-time as an interdimensional broker. One day, the Marine Hero, Garp, complained that I'm scammer and tried to flip over my stall. In retaliation, I threw him straight into an otherworldly dungeon! Ding! [Client Selected: Monkey D. Garp!] [Dungeon Generating… Dungeon World: Naruto!] [Mission Objective: Survive the Third Raikage’s assault, or defeat him!] Garp: "Stinking brat! What kind of ghost place did you send me to!"

Clear Evaluation: S+!] [Congratulations, you obtained SSS-Rank Reward: Eight-Tails Perfect Jinchuriki!] [Congratulations, you obtained S-Rank Reward: Lightning Release Chakra Mode!] Feeling the lightning and Tailed Beast chakra surging through my body, I laughed aloud.

He knew every secret in this world. Every devil fruit. Every hidden power. Every hero who would rise — and every person who was going to die. He thought that made him untouchable. Then he opened his eyes in a seven-year-old body, in a world where the seas can swallow ships whole, Marines shoot first and ask nothing, and the most dangerous pirates in history are still very much alive. All that knowledge? Useless without the power to back it up. And the System that appeared before him wasn't here to make things easy. It had one message: "You know how this story ends. But you changed it the moment you arrived. So tell me — how much of what you 'know' is still true?" Now he has three years. Three years before the boy in the straw hat sets sail and tears the world apart. Three years to grow strong enough to survive what's coming. But there's a problem. The timeline is already broken. The people who were supposed to live — might not. The people who were supposed to die — might not either. And somewhere in a Marine prison, the future greatest swordsman in the world is locked in a cage — three years too early. His brain says: stay hidden, stay safe, survive. The System says nothing. But the clock is ticking. This is not a story about a hero who saves the world. This is a story about a boy who knows exactly how brutal this world is — and chooses to step into it anyway. Welcome to the Grand Line. Try not to die.

But when Roy was actually dragged into Marineford by the scruff of his neck by Garp the Fist, his mind went blank— "Hey! Where's my 'New Reincarnator Starter Pack'?! Where's my System bonus?! Why is this crazy old geezer forcing me to do ten thousand punches a day?!" And so, under Roy's influence, the entire vibe of the Marines began to go completely off the rails... ▷ Luffy: "Check it out!

Have you ever heard of a 'Compressed Supernova'?" ▷ Zoro, Kuina, Law, Nami, and Nojiko... one by one, all get tricked, roped in, or just plain kidnapped into joining the Marines...

Hiroto arrives in the world of One Piece thanks to the almighty Truck-kun. Thankfully, he acquires an entry [Transmigrator] for achieving the miracle, which gives him the possibility of entry extraction, fusion and granting.

Returns to original state after cancellation.] [Entry: Effort King] [Effect: Experience categorized as training or learning is multiplied by 200 times after settlement.] [Entry: Fiery Heart] [Effect: Adds fire damage to any attack. The range, power, and temperature are determined by the amount of stamina invested.]

From that day on, the balance of the Grand Line is shattered as his ship becomes a gathering place for beings that defy common sense. First, a Winged Demon descends, her absolute defense mocking Admiral Kizaru's speed of light. She is followed by a Cold-blooded Arrancar, whose green energy blasts bring despair to the absolute justice of Enies Lobby. As they enter the New World, the crew grows even more terrifying. A red-eyed girl, the Wielder of the Demon Sword Murasame, slays a Billion-Berry Calamity with a single scratch. The seas tremble as the Ghost of the Uchiha dares to dance with the Soul Queen herself, while the God of Shinobi treats the 'Strongest Creature' like a mere whip. Finally, an Ice Queen freezes the very ocean just to alleviate her boredom, accompanied by Steel Warships that transform into girls, bombarding enemies with heavy artillery. Sengoku: "Report!

In the defeated world, everything would vanish, becoming fuel for the evolution of the victor. Among the two worlds, only one world would survive in the end. This was the evolution of the world.

Yuichi thought, "A battle between worlds! The Ninja World is manageable, but if it were Shinigami, Dragon Ball, or One Punch Man..." ... [Note: This is an unofficial translation.
