Others transmigrate into the world of One Piece blessed with a Prophet System—a cheat that guides every step. But Gern Reginald Sigmar arrives in a far crueler era: the Dark Ages of Rocks. The script? Long since shattered. A system? It never existed. The only path left to him is brutally simple—join the Navy and survive. After four grueling years of relentless struggle, he finally becomes a mere private, then even takes out a loan, risking everything to pull strings and force his way onto the battlefield of God Valley. Yet before they can even reach the central zone, he is crushed by overwhelming Haki again and again—his consciousness shattered no fewer than fifty times. When he opens his eyes for the final time, a mysterious fruit of unknown origin lies in his arms. Without hesitation, Gern makes his choice and bites into it. In that instant, space shatters. The atmosphere howls. His body transforms into the very source of devastation itself, and with a single motion, the air trembles as if the world were about to collapse. A Logia-type Devil Fruit—the Heaven-War Fruit! Gern stares in disbelief. “Huh? Aren’t these familiar effects supposed to belong to a Paramecia? How the hell is this classified as a Logia?!” From that moment on, Marine Headquarters gains something unprecedented—a humanoid natural disaster. And so, Gern declares his justice: “Get out of the way. I’m about to begin the execution of ‘Shaking’ justice!” In time, this becomes the creed of the man who will stand at the very peak as a Marshal: “If justice must rely on natural disasters to be reshaped… then let it begin today.” My justice is natural disaster.

Transmigrated into the turbulent world of shinobi, Ikki found himself thrust into the heart of the bloody Warring States period. He was no ordinary ninja; he had awakened a "system" that granted him the legacy of a legend—an enhanced version of the "Iron Fist," Monkey D. Garp. Unlike the common shinobi whose prime withered with time, Ikki defied the laws of nature. Age was not a burden to him, but a catalyst; the older he grew, the more his monstrous strength intensified. In an era defined by bloodlines and ocular jutsu, he had relied on nothing but his bare, iron-hard fists to beat both the Senju and Uchiha brothers into submission. His intervention brought the chaos of the Sengoku era to a definitive end, earning him the title of the world's greatest "Shinobi Hero" and the undisputed top rank among the Three Great Masters of the age. However, as the era of warring clans transitioned into the age of Hidden Villages, Ikki chose to fade into the shadows. Disillusioned by the endless cycle of conflict between ninja and samurai, he retreated to the secluded back mountains of Konoha. There, he lived as a forgotten relic, an old man whose name had slipped from the pages of history into the realm of myth. Peace, however, was a fragile thing. The Third Shinobi World War erupted with a ferocity that threatened to consume everything. The "White Fang" of the Leaf had fallen to his own blade, and the legendary Sannin were pinned down on foreign fronts, leaving the village vulnerable and desperate. With Konoha standing on the brink of ruin, the village leadership—the council of four led by the Third Hokage, Hiruzen Sarutobi—was forced to make a desperate pilgrimage. They went to the mountains to plead with a legend they had hoped never to disturb. After decades of silence, the Hero of the Sengoku was coming out of retirement.

Awakening from the world of One Piece, will you choose to drift with the tide or take control of your destiny?

PS: This story is serious; please be gentle if you don't like it. Reasonable discussion among One Piece fans is welcome.

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?”

I, Natsuki, was reborn in Konoha as a classmate of Kushina Uzumaki. My start was ordinary, but my destiny was not. A system awakened within me, offering me the world on a silver platter. My cheat? A [Gacha Template System] that allows me to draw and fuse with character templates from across the multiverse. With every pull, I became someone new, someone stronger.

And a legendary pull blessed me with the transcendent cunning of Aizen Sōsuke. As these legendary templates merged into one being, the Shinobi World finally met its new, undisputed ruler.

Jinx was a lazy, daydreaming drifter with a sharp wit and a heart full of strange wisdom, raised by a kind-hearted prostitute who taught him the value of survival, charm, and reading people like open books. He never judged her—how could he, when her world gave him the skills to navigate his own odd existence? His days were quiet, filled with idle strolls and wild thoughts—until one day, the gods above, bored and careless, disrupted his life with three bizarre, back-to-back accidents. He survived them all. Fate, however, wasn’t finished. His end came not from divine wrath, but from something far more mundane—his neighbor’s clumsy attempt at cleaning a loaded gun. Death took him to the void, where time stretched longer than the birth and death of the universe itself. There, in endless nothingness, Death offered Jinx a single, impossible chance at life. He took it. But when Jinx opened his eyes again, it wasn’t to the world he knew. It was a fractured realm teetering on the edge of madness—and his return was the spark that would set the chaos ablaze.
