One Piece: Starting with Mugen Mugen no mi

NO SMUT. JUST KISSING. I was murdered by the two people I loved most—my fiance and my stepsister. Sickly, weak, and foolishly kind, I couldn’t even fight back. As I lay dying, I remembered all the novels I used to read—stories where villainesses lived fiercely, beautifully, without regret. I wished I could be like them. Then a voice echoed in the darkness. "Congratulations, host. You’ve been chosen for the Villainess System." Now, I’ve been reborn in a new world—strong, powerful, and feared. This time, I won’t be the victim. I’ll be the villainess… and I’ll decide how this story ends.

Kai woke up in the Naruto world, but he wasn't a hero. He was just a regular Uchiha, stuck in the middle of a huge war. The Fourth Hokage was about to arrive, and things were getting dangerous. Suddenly, a voice boomed in his head, "Ding! One-Click Max Level System activated!" Kai was confused, but then he realized he could learn any jutsu he wanted, instantly! "Great Fireball Technique? Done! Max level!" He blasted a giant fireball with ease. "Shadow Clones? Done! Max level!" He was surrounded by dozens of his own copies. "Sharingan? Done! Max level!" He could see everything in slow motion, and his eyes glowed with power. "Sage Mode? Only one in ten thousand can learn it? Done! Max level!" Kai was unstoppable. He could learn any jutsu, no matter how difficult. The war was about to get a whole lot more interesting.

On a perfectly average Tuesday, Dustin's nap got interrupted by the end of the world. A new reality. A system. Classes, stats, and a monster filled forest where dying means staying dead. In a world built for the bold, the brave, and the physically fit, Dustin got assigned the Rogue class. He has not jogged in five years. In a place that should terrify him, surrounded by people frantically forming armies and charging into danger, Dustin finds himself thinking one thing. Finally. Something interesting. Perhaps the laziest man alive was always meant for a world like this.

Ethan Kane was just another comics fan until he woke up in a world where Marvel’s heroes and villains weren’t on the page—they were real. Thrust into New York at the height of masked battles and hidden agendas, Ethan discovers he carries something no one else does: a mysterious system that lets him analyze and copy powers. With gods, mutants, and monsters clashing around him, Ethan must play the role of an ordinary student while secretly navigating a dangerous game of survival. Every choice—every power he dares to claim—could turn him into prey for heroes, villains, or both. In a universe built on masks, alliances, and betrayals, Ethan faces the ultimate question: will he simply survive, or reshape the world with the knowledge and abilities he gathers?

A group of young men, drifting deeper and deeper into delinquency, eventually commit murder. Forced to flee, they settle in an abandoned land where they build their own village—Watch Dal—and adopt the shared alias “Dal.” Watch Dal soon becomes a refuge for delinquents and criminals of every kind. Not far from there lies another village, Deuk Wolof, a peaceful place where life is good. But its inhabitants soon begin to suffer from the provocations of those from Watch Dal. Will they be dragged into a spiral of violence that this uneasy coexistence is bound to ignite?

The night Kael survived the hunt should have been the night he died. Marked by a force no one fully understands, Kael returns from the mission changed; touched by the Moon, yet tethered to something far older and far more dangerous. The Conclave calls it a blessing. The veterans call it a curse. Kael calls it control. In a world where humanity lives on the edge of two cosmic forces. Hunters are sent into the dark to contain the Pale Reach—an unknowable force that twists beasts, breaks minds, and devours the unprepared. Power is survival. Emotion is weakness. And Kael has built his life on being unbreakable. Cold. Precise. Disciplined. But the Moon does not grant power freely. The stronger Kael becomes, the louder the whispers from the Pale Reach grow. To resist it, he must resonate with the Moon. As threats escalate beyond anything the Order has recorded, Kael finds himself standing at the fault line between two worlds, the silent pull of the Moon and the all consuming hunger of the Reach. Hunters begin to fail. Cities begin to fall. And something ancient is awakening. Kael was trained to eliminate monsters. Now he must decide whether he will become the very thing he hunts or become something entirely new. Because the Moon does not choose the worthy. It chooses the necessary.

The Primordial Luminary created the Primordial Galaxy countless eras past, before disappearing into the vast expanse of the universe. Many eons later in the Primordial Galaxy, an elder species called Dragons, evolved into mighty sages pursuing the path of enlightenment of the Primordial Luminary, and this pursuit of enlightenment created within them a sense of moral superiority. Another mighty species also arose in this Galaxy, and they were the Eldans, who did not pursue the path of enlightenment, but power. The Eldans established the most successful galactic empire. But the Dragons had long been uncomfortable with the uninhibited nature of the Eldans, and the chance to punish the species came when the Eldans sought the genocide of an artificial species that the Dragons had created by studying their genes. The Dragons and their allies waged war against the Eldan empire, leading to the third galactic war. The Eldans were defeated, and spared from extinction by being exiled to the continent of Helleny in their birth planet of Depheron. They were forbidden from ever appearing in the galaxy again. Thousands of years have passed since then, and an Eldan has risen to defy the order of the Dragons and their endorsed rulers of the Galaxy. But to stand against the might of the new galactic empire and the more powerful Dragons would require more than mere determination or a large army. It would also require the even more difficult and mythically impossible breakthrough to the unknown realm of Supreme Overlord which the Primordial Luminary attained countless eras past...
