I exist in multiple worlds at the same time. Naruto, One Piece, Marvel, magical realms—each world has me, and every version shares power, knowledge, and growth. While others struggle to survive one world, I build empires across many. Orochimaru’s gaze lingers longer than it should. Dragon notices the revolutionary book I secretly authored. Uncle Jiu freezes when I draw talismans directly in the void. The more worlds I enter, the more dangerous I become. This is not a hero’s journey— this is a calculated rise to absolute control.

Meiser, a mixed-blood descendant of the Uchiha and Senju clans, rose to prominence during the Second Shinobi World War.

The Good News: I was reborn into the Zenin Clan, one of the Three Great Families of the jujutsu world. The Bad News: I was born with zero Cursed Energy. A reject. ​But a childhood tragedy didn't just break me—it awakened my bloodline. The Mangekyō Sharingan. ​With these eyes, I wield a divine power capable of absolute destruction (Amaterasu) and an ethereal defense that renders me untouchable (Kamui/Susanoo). Armed with the terrifying Gedo Mazo (Demonic Statue of the Outer Path) and a Special Grade Cursed Tool unique to me, the "failure" of the Zenin clan is ready to rise. ​To me, Sorcerers and Cursed Spirits are nothing more than tools to pave my path to the pinnacle. ​Gojo Satoru claims to be the strongest in the modern era. Ryomen Sukuna reigns as the strongest in history. But what of Zenin Mirai, the one who trampled the strongest of two generations? ​The throne that commands all sorcerers and spirits... Two thrones sit side by side at the peak. But is there enough room for one person to sit on both? .... ..... ..... ​Not a fan of monthly subscriptions? You can now send a one-time tip via Gumroad!

Waking up to Nami's CPR was a good start. Finding out he had been transported to the world of One Piece in a younger, fitter body was even better. ​But the real game-changer was the Devil Fruit he accidentally devoured. It gifted him a strange, versatile physiology—capable of invisibility, electricity, and modifying his own body structure—rooted in the power of Dual Cultivation. Now, as he travels the seas, his philosophy is simple: let Luffy be the Pirate King. He is destined to be the Sea King, growing stronger by bringing happiness to the women of the Grand Line. .... ..... ..... Discord:https://discord.gg/Rntx3SxvYj

After transmigrating into the brutal world of pirates, you might think the goal is to lie low and survive. But where is the ambition in that? ​Atlas D. York, a timeline anomaly with no "System" to save him, gambled his fate on a single wish: The Paramecia Hapi Hapi no Mi (Happy-Happy Fruit). ​His philosophy? Simple. "I have only two wishes in this life!" "First: Wake up and rule the world!" "Second: Fall asleep drunk on the lap of a beauty!" ​"Can I do it? Who knows. But I will die trying." "As for dying? If I’m weak, I deserve it!" ​"Step one to realizing the dream: Join the legendary Rocks Pirates and learn from the best!" ​... ​Decades Later. ​Atlas D. York sits upon the Empty Throne in the Holy Land of Mary Geoise, the undisputed ruler of the world. ​Surrounding him is a legion of the sea's most beautiful women in maid outfits—including the Pirate Empress, the Demon Child, the Cat Burglar, and even the mysterious Im herself. ​Facing the cameras broadcasting to the entire world, he raises a glass and grins. ​"Everyone must have dreams. After all... what if they actually come true? I am the best example!" .... ..... ..... Discord: https://discord.gg/Rntx3SxvYj

A graveyard for souls. A playground for monsters. Monkey D. Luffy sets out into the East Blue with a single, absolute ambition: to become the Pirate King of all the Blue. But on these unforgiving seas, raw determination isn't enough to survive. Every island holds deadly consequences, every clash leaves scars, and the sea shows no mercy to naive boys in straw hats. To conquer the Grand Line, Luffy must build a crew, survive the brutal environment of not just the seas, but also different kinds of demons sailing onto them. Will Luffy’s name ring across the world as the Pirate King? Or will the ruthlessness of the deep drown his ambition, turning his tale into just another ghost story lost beneath the waves? ————————————————————————————— Author's Note: Welcome to Two Piece: REWRITE! Like many long-time fans, I love One Piece, but I’m writing this story to create my own definitive take on the ocean world. Truth be told, as the canon narrative evolved, it didn't fully deliver what I personally wanted out of the series. This reimagining isn't just another 1:1 copy of the original plot. My goal is to make the world darker, grittier, and higher-stakes while still retaining Oda’s signature goofiness, heart, and core ingredients. You’ll also notice the scaling is tuned up to make the world feel more dangerous and powerful, but don't worry, Luffy won't be blowing up planets pre-timeskip, but you'll definitely see the shift in power as the story unfolds! Expect total creative freedom, sharper action, earned consequences, and a plot inspired by some of the fandom's best ideas.
