This novel is just fan fiction and the only thing that comes from me is all the new characters and places that I have added. Just a try at the suggestion of my friend to create a ko-fi account and this is a pure donation without additional chapters.

The Jura-Tempest Federation is lively as ever on this particular afternoon. "Wahahaha! Kai-chan, give up! You can't catch me!" Milim, hands on hips, gloated shamelessly at the young man hovering in the sky above her. "Milim. You stole Rimuru's pudding again." "Hehe! I'm the Demon King!" A silver-haired maid appeared silently behind her, pocket watch in hand. "Milim-sama. Three days. No pudding." Milim slowly turned around. "S-Sakuya! It was Rimuru's fault, I swear!!" The maid grabbed her by the collar and dragged her off without another word. "AHHHHH!! I know I was wrong!! Kai-chan, SAVE ME!!" The roadside crowd watched on. "Fifth time this month." "The Demon Slayer Corps is basically a road repair team now." "At least you only have roads. Milim-sama sank an island in the pirate world last week. Admiral Akainu broke four desks." "Don't even get me started on the Ninja World..." Kaito watched it all unfold and quietly mourned. 'Milim... my peaceful life.'

Ikki Kurogane transmigrates through the world of One Piece and awakens the "All Great Swordsman" system.

With this knowledge, Ikki sets his sights on various swordsmen across the Grand Line. When the Summit War erupts at Marineford, Ikki arrives with his partners, each wielding extraordinary weapons: Ikki: "Cleave the heavens and moon, Zangetsu!" Nami: "Pierce, Gonryōmaru!" Nojiko: "Purify all, Minazuki!" Robin: "Scatter, Senbonzakura!" Kalifa: "The Flowery Winds Become Disturbed, The God Of Flowers Sings, The Heavenly Winds Become Disturbed, The Devil Of Heaven Sneers, Katen Kyōkotsu!" The assembled Marines and pirates at Navy Headquarters fall silent in shock. Fleet Admiral Sengoku: "All Great Swordsman? What manner of power is this?" Dracule Mihawk: "Zanpakuto? Impressive blades indeed. But to think you could take my sword... How amusing."

After all — this is no longer Luffy’s story. This is Rolan’s era — the tale of a man reborn to live as he wishes, in a world where only the strong can truly be free.

A grounded modern man with fairly normal values, Ash has zero interest in becoming a so‑called pirate chasing “freedom on the seas.” If anything, joining the Navy seems like the most reasonable way to survive this insane world. Unfortunately, reality has other plans. Before Ash can even make his choice, he’s mistaken for a pirate and slapped with a wanted poster by the very Navy he planned to join. Just when things hit rock bottom, a cheat activates. Devil Fruit Editor! Within the rules, freely design and create incredible Devil Fruits. Ash: “Devil Fruit Editor?

Two days later, Ash opens the World Economic News and sees his own wanted poster staring back at him. Bounty: 800 Berries. Ash: “What the hell is this?! Eight hundred?! A man can be killed, but not humiliated! World Government, Navy, remember this. I’ll collect this debt sooner or later.”

Blake (playing with his fingers in boredom): "I think my current status is pretty high. There's no need to raise it any further." Life and death battles increase your domineering strength!

Blake (with a puzzled look on his face): "What does their suffering have to do with me? What will I do if they change the world?" Yim is too strong to be defeated! Black (reassured): "But there's still Luffy. I'll fight him after he's done!" Why do you dare to participate in the battle between gods and demons? Blake (crooked mouth): "I! Have! Hang!" This is a Gou Dao Tianlong person, get out! Blake (struggling): "I don't accept it! Why can't the Celestial Dragons just hide?"

In a dead world overrun by walkers, Gray gains access to a system capable of buying almost anything: weapons, skills, powers... even abilities from other universes. At first, surviving The Walking Dead seemed simple enough. Then he discovered Rebirth. A feature that allows him to travel between worlds while permanently keeping some of the powers he earned. Now, every apocalypse, every universe, and every battle is a stepping stone toward something far bigger. And Gray plans to survive them all. First time doing this, so don't expect award-winning writing. Might also mess up timelines or places but just take it as an AU :)

A behind-the-scenes mastermind flow, vest-flow story. Transmigrating into the world of One Piece, Genichi gains the power to harvest emotions and draw character cards. And his first move… Unleashing the Nine-Tailed Fox to wreak havoc on Sabaody and bombard the Holy Land of the Celestial Dragons. From there, tales spread across the seas of a yokai’s “Invisible Empire,” fragments of the Shikon Jewel—said to grant any wish—pursued by the rulers of the seas, a devil who made a contract with the Five Elders of the World Government, the strange and eerie Bikini Bottom lurking within the ocean, the Sixth Demon King descending upon Wano, a ghost searching for the blue spider lily on a small island in East Blue, and the mysterious port of Utopia alongside the Gravity Spring… All of it—every legend and upheaval—was orchestrated by Genichi’s hand.

A modern-day beauty, Luna, is suddenly transported into the world of One Piece. In a world defined by freedom and adventure, she decides that if she’s already here, she might as well leave her mark. Who says women are inferior to men? If this world has a throne, then she’ll claim it and become its queen. From the very beginning, Luna awakens the System, receives a beginner’s gift pack, inherits Greeza’s power template, and unlocks all three forms of Haki. And that’s not all—her identity itself is far from ordinary. She begins recruiting crew members from the original One Piece world, including Kuina, Carmen, Kaya, Nojiko, and Uta, all of whom survive and join her journey.

A completely different fate. Starting from East Blue, Luna crushes every obstacle in her path—rising to become the Fifth Emperor of the Sea, overwhelming the Marines, destroying the Celestial Dragons, beating down the Five Elders and Imu, and ultimately dominating the pirate world. All to become a World Queen, admired and worshipped by countless people. Shanks: “The Sister Pirates? Interesting. Then Uta is yours.” Usopp, Sanji, and Nami: “Kaya… Carmen… Sis… what happened to you?!” Vegapunk: “Unbelievable. My research abilities are inferior to a teenage girl.” Sengoku: “Why is an all-female pirate crew this terrifyingly strong?” Garp: “You’re his granddaughter, aren’t you?” Luffy, letting out a sigh of relief: “Good thing no one’s stealing my title as Pirate King.” And deep within the shadows, Imu screams in despair: “Can someone tell me… how do you fight the Void?”
