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.

Ron transmigrated as a scientist. At the start, he saw Blackbeard kill Thatch and steal the Dark-Dark Fruit. He activated the Black technology system and obtained the "Devil Fruit Enchantment Technology," which is very simple to understand - it's about giving a Devil fruit users additional abilities! At the beginning, he extracted Marco's Phoenix fruit and enchanted Whitebeard with it. The Tremor-Tremor Fruit + Phoenix fruit came into existence... Then he extracted Whitebeard's Tremor-Tremor Fruit ability and enchanted all his sons... As a result, a bunch of Tremor-Tremor fruit users were born! Following that was the "Conqueror's Haki Replacement," where everyone possessed Red-haired Shanks' top-tier Conqueror's Haki... This scared the shit out of the Five Elders'!

In a world ruled by strength and chaos, a soul from modern Earth awakens in the frail body of a seven-year-old Sakazuki. Orphaned by pirates and left with nothing but a burning hatred, he refuses to remain weak. With knowledge from his past life and the power of the Magma Magma Fruit, he begins his ruthless ascent through the ranks of the Marines. But justice is not so simple. Corruption festers within the very institution meant to uphold order, and the line between protector and tyrant blurs with every battle. Undeterred, Sakazuki will forge his own path—one paved with fire and blood. From a vengeful child to the most feared force in the Marines, witness the rise of a man who will set the seas ablaze and redefine what it means to bring order to a chaotic world. 100 Power Stones = 1 Bonus Chapter ••••••••••••••••••••••••••••••••••••••••••••• ● I do not own anything related to One Peice, this is purely a fanfiction.

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
