Shun's new life in the world of Fairy Tail began with a bang—literally, as he crash-landed on Tenroujima as a toddler. Armed with a "System" that grants him incredible powers like the Paw-Paw Fruit and memories of this world from the anime he once loved, he's determined to live a life of adventure and become the future Guild Master. But the System keeps hinting at a past he can't recall, offering "Memory Fragments" of a history far more complex than that of a simple office worker who died in a mundane accident. As Shun carves his legend into the guild, he must uncover the truth of who he really was, and why such formidable, forgotten enemies seem to know his name.

Ryoma mysteriously transmigrates to the world of Fairy Tail. But unfortunately, he remains a non-mage for seven years, becoming an ordinary person in the guild. But one day, the dormant dimensional power in his body throws him into the Demon Slayer world. There, his Ice Breathing merges with his magic power, and finally, he gets an effective magic, Ice Magic. And this was just the beginning. The dimensional power within him erupted from time to time, throwing him into various different worlds again and again. Ice Magic from Demon Slayer's breathing style, Space-Time magic from Black Clover's Grimoire, Conqueror's Haki, Imperial tools, Zanpakuto... Each time he returns, only a moment passes in the Fairy Tail world, but he rises with new powers. With these newfound powers, Ryoma will eventually write the legend of the Dimensional Mage.

In the middle of the vast ocean, consciousness returns to a man with no past. Ulquiorra opens his eyes to endless blue sky and water, with no memory of how he got there, only a burning, inexplicable need to find something called "the heart." He doesn't understand what it is or why he needs it so desperately. But the compulsion drives him forward. This is his journey through the One Piece world. A search that leads Ulquiorra to discover what he was really looking for all along, not an object, but the ability to feel. To truly live. *** No Pokemon harem bullshit here—max 3 love interests if things go that way. Fair warning: my memory's shaky, so this is a *slight* AU. Some canon details might get fuzzy. Ulquiorra joins the Straw Hats eventually, but it's not just "add one hollow guy to the crew and retell everything." His presence actually breaks shit. Events change. Things don't go down the same way, and the story goes sideways from there.

Prepare for a frostbitten tale where consequence is frozen solid. *Blue Pheasant (Kuzan) does not appear in this work. Please follow/support at: https://www.patreon.com/ZenpaiTrans

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

In the world of One Piece, Arton, a sketch artist, suddenly finds himself face-to-face with a Celestial Dragon—and not in a good way. Lucky for him, he awakens a system that allows him to gain strength by writing in a diary. Fired up for some payback against the Celestial Dragons, Arton embarks on a journey, and not just for retribution but also to meet beautiful girls such as Nami, Robin, and Hancock—characters he's drawn a million times before. As his journey unfolds, Arton starts scratching his head, wondering why women like Uta, Vivi, and Hancock are lining up to join his crew. Nami throws him a compliment, "Thanks, Arton, you're the best." Carina playfully proposes a trade, "Nami, you keep the treasure, and I'll have Arton, okay?" And Nico Robin teases, "Arton, you're into more mature women, aren't you?" ***This is a translation*** original: https://b.faloo . com/1299406.html

A 15 year old guy travels to an almost all female One Piece world, in the year 1521. Heavy AU vibes according to characters and plots. There are lots of characters that are going to be genderbent, and this is going to be a large harem, due to it being a Matriarchal society, almost. I'm most likely killing off a lot of characters, so if I like them, they are not getting killed off. The MC is going to be short, because I have not seen lots of short MCs (he is 5 foot 7, I'm not making him tall idc) He has a system, but it isn't going to talk, because what is the point of a talking system, it's only there to make my life easier by providing him an upgrading ship and some other things(including reviving and reversing) He is not overpowered, because I want to make this fun and not only about smut ( there are sex scenes) I'll make him overpowered though. He will also lose fights, and I'm going to up some power levels (Midarland Gooner) so I can at least try to make his crew not all powerful by the end (if I finish) Provide constructive criticism because this is my first time writing a fanfic, so be as hard (pause) as you can to me. Disclaimer- I don't own One Piece, of course I fucking don't. I'm British, so I'm going to write differently than Americans. I also don't write consistently, so don't expect daily chapters or whatnot. Idk what else to say.

First year in the Marines “Loyalty, Justice, Courage!” Fifth year in the Marines “If you don’t take it, and I don’t take it, then how could Admiral Sengoku ever take it? And if Admiral Sengoku doesn’t, how are we supposed to move forward?” Tenth year in the Marines “Fleet Admiral Sengoku, why won’t you stand up and clash head-on with the Five Elders in Mary Geoise?” That year, Ortoren enlisted as a fresh recruit, his head full of ambition—dreaming of rising through the ranks and seeing the world for himself. Years later, Ortoren became commander of G-5, leading nearly eighty thousand elite frontline Marines. By then, loyalty was all he had left to cling to. Later still, he rose to Admiral of Marine Headquarters, entrusted with overseeing the New World. With hundreds of thousands under his command, his power rested on one simple truth: “The Five Elders praise my loyalty and courage, and Fleet Admiral Sengoku treats me as if I were his own son.” In time, Ortoren commanded armies numbering in the millions. At his word, the seas themselves seemed to tremble. One day, as he walked through Marine Headquarters, a group of officers suddenly surrounded him. They overpowered him—the strongest man on the seas—and draped a yellow robe across his shoulders. “It’s cold, Admiral,” they said. “You should wear something warmer.” Looking into the earnest eyes of those officers, Ortoren let out a long, weary sigh. “After all these years of loyalty, my name is ruined in an instant. You’ve truly done me in.”

During an internal Navy hearing, the top brass conducted a serious inquiry into Rogers Daren, the so-called "scum of the Marines" and Admiral of the North Blue. "You’ve had improper relations with royal princesses and noble ladies from multiple North Blue kingdoms?" "I call it showing care for the people." Marines High Command: … "How do you explain the absurdly high salaries of the North Blue Marines under your command?" "Well, with what the HQ pays, how else do you expect them to risk their lives?" Marines High Command: (ーー`) "Why is the North Blue fleet equipped with technology from Germa?" "That’s just military-civilian cooperation. Germa 66 was moved by my sense of justice." Marines High Command: (○_○) "And how do you explain the unusual deaths of a Celestial Dragon in the North Blue?" Daren sighed. "A maritime accident… truly unfortunate. I personally express my deepest condolences." Marines High Command: (._.?) And so begins the story of a rebellious, unorthodox Marine.
