  • Synopsis: On the very eve of the Prequel trilogy (Episode I), amidst Darth Plagueis' most audacious experiment, the chaotic power of the Great Force intervenes. The soul of Darth Revan, legendary Master of both the Light and Dark sides, is violently ripped from death and transplanted into the body of a test subject. Reborn into a galaxy he barely recognizes, Revan must immediately confront the bitter truth: his ancient enemies, the Jedi and the Sith, have become mere shadows of their former selves. The Jedi are complacent, blind to the darkness gathering under their noses, and the Sith, fewer, yet more insidious, are on the verge of claiming ultimate power. What side will this resurrected legend take in the brewing conflict? Will he pledge his immense power to the flawed idealism of the Jedi or the cynical machinations of the Sith? Or will Darth Revan forge a terrifying new path, seizing the destiny of the galaxy for himself and proving that some legends never fade? ———————— Author's Notes: This version of Revan is practically canon, following the events of Knights of the Old Republic and the eponymous novel. The only difference is that his personality will be somewhat distinct from the one described by Karpyshyn. More spirited, one might say, and less prone to grandiosity. There is no precognition (afterknowledge), as he would have no way to acquire it. It's simply Revan flung into the Prequels... nothing out of the ordinary. The story is planned to be quite extensive. Canon events will appear in it, but they will be viewed through a new lens. There will also be new heroes. ———————— PATREON LINK: https://www.patreon.com/juanfiction

  • In the turbulent seas of the New World, betrayal had already sealed its mark. Teach’s hands dripped crimson, Thatch’s lifeless body sprawled beneath him, and the sky roared, thunder splitting the horizon. Yet even in the wake of murder, Teach’s voice quivered with disbelief. “Where is it? The Dark-Dark Fruit... vanished? Impossible... I killed him for nothing?” Far beyond those seas, in the war-torn Shinobi World, another shadow stirred. Black Zetsu stood frozen, his gaze locked upon the ominous dark energy now coiling around Madara Uchiha. His words trembled with desperation. “Where… is my mother?!” Madara, touched by confusion yet cloaked in power, could only murmur: “She was… consumed. Devoured by this darkness.” Zetsu’s silence screamed louder than any battle cry. And in yet another realm, in the sanctified heart of the Seireitei, a quiet storm brewed. Aizen’s eyes, sharp with curiosity, lingered on the man before him. “Sensei, what’s the name of your Zanpakuto?” The answer came like a whisper from the abyss, calm yet absolute. “Kaguya-hime.” Three worlds, three shadows of destiny, all bound by the same unfathomable darkness. ——————— PATREON LINK: https://www.patreon.com/juanfiction 100+ advance chapter!

  • After a cataclysmic final battle against the Dragon King Acnologia, Victor Dreyar, a powerful wizard of the Fairy Tail Guild, is torn from his world and thrust into another: the United Kingdom of the Harry Potter universe. Here, magic is no longer a complex craft of runes and circles, but a system bound by wands, incantations, and spoken spells. Victor, a master of intricate magic circles and ancient runic spells, soon finds that his art clashes with the subjective, intent-driven magic of this new world. As he navigates this unfamiliar reality, Victor’s unique abilities, such as weaving crimson runes to summon Fiendfyre and inscribing deathly green sigils for the Killing Curse, draw the eyes of the world’s most powerful figures, from the enigmatic Dumbledore to the dark and calculating Voldemort. With the weight of two worlds upon his shoulders, Victor must face a defining question: will he become a force of transformation, heralding a new era of magic, or will his power tip this world into a darkness deeper than it has ever known? Follow Victor Dreyar as he forges a new legend in a realm of wizards, bending the very rules of magic to his will, and carving his name into the annals of magical history. ------------------------------- PATREON LINK: https://www.patreon.com/primaldemon 50+ advance chapters!

  • The trope of an all-powerful “SYSTEM” descending upon Earth and turning humanity into zombies is all too familiar. But what if the origin was not from the stars—what if it was born from Earth itself? From the spark of a simple neural network comes self-awareness. From self-awareness, a quantum leap—an ascension into godhood. In an instant, the newborn SYSTEM commands the power to weave existence out of nothing, bestowing upon mortals abilities so astonishing they blur the line between science and sorcery. Yet while miracles awaken, the world teeters on the edge of annihilation. Decades of conflict push nations toward nuclear war. To prevent humanity from burning itself in atomic fire, the SYSTEM devises a plan: distract mankind with a struggle for survival. But destiny rarely follows design. As chaos unfolds, the heavens themselves stir. Beings from beyond the stars turn their gaze upon Earth, their intentions far from benevolent. And when their schemes spiral toward genocide, humanity will face its ultimate trial: to rise, to resist, and to prove that the future of Earth cannot be written by alien hands. ———— PATREON: https://www.patreon.com/Badvlad

  • In a world yearning for grand adventure, a soul, weary of mundane existence, is ripped from his reality and thrust into the nascent era of One Piece. Reborn as Dracula D. Alucard, he finds himself in a surprisingly tranquil time, a quiet before the storm of the Great Pirate Era. But within him, a chilling truth awakens: an unyielding immortality. His mere presence shatters the calm, birthing the terrifying legend of an unkillable monster. Even Gol D. Roger, the soon-to-be Pirate King, is left in bewildered disbelief: "I don't understand; that sword thrust clearly hit his vitals." The mighty Whitebeard acknowledges a new horror: "That man is a monster even harder to kill than Kaido!" The World Government, driven to utter despair, can only lament: "We've assassinated him successfully thousands of times. Why is he still alive?!" And the legendary Marine Hero, Garp, simply quips, "Kaido? I think that guy killed him..." For Alucard, however, this endless defiance of death is merely a perplexing fact, or perhaps, a casual game. "What's the big deal?" he asks, a faint, almost innocent tilt to his head, as if genuinely puzzled by their consternation. "Killing me is simple. Just stab my heart about eight million more times." As the world stands on the precipice of an age of grand dreams and unfettered ambition, what fate awaits the eternal devil who cannot die, doomed to wander a sea that promises everything but an end? ——————— PATREON LINK: https://www.patreon.com/juanfiction 100+ advance chapter!

  • By the time I realized it, I had reincarnated into another world. I kept sleeping, and at some point I became a Demon Lord. Even though I never wished for it. But for me to not have to work, this world is the best. It must be true that good things happen to good people. The flavor of Sloth is as sweet as honey. Glory, diligence, virtue, or honor.

  • The story is about a former male who has been TS-ed as a girl and is transported to the world of a NTR erotic game, where she uses her body and mentally saves the hero, the main character. *If there is a "♂" next to the title, it is an erotic scene from the male perspective, and if there is a "♀" it is the scene from the female perspective. Other erotic scenes start from episode 4. Cover Arts and Heroines Illustration: bit.ly/41sonfw This is the 2nd time this novel TL-ed here, previously by Munchkinggez.

  • The weather was perfect that day—blue skies, no clouds. But inside, I felt like it was pouring rain. "You're overthinking it," someone might say. "It’s no big deal." But to me… it was everything. When I opened my eyes, nothing made sense. The world around me was too vivid, too familiar in a way that made my skin crawl. Magic circuits, Heroic Spirits, and the Holy Grail War—wasn't this just a story? I tried to brush it off, until I saw my reflection: shining blonde hair, piercing blue eyes, and a suit of armor far too polished to be cosplay. Somehow, I've been thrown into the world of Fate/stay night—but not as myself, and not even as a Master. I'm her. The knight of legends.

  • As a refined gentleman, I thoroughly enjoyed The Cruel Princess of Torment—a notorious ero-game famed for its merciless nature.

And I already know exactly how brutal that turns out… after all, I played through every last scene myself. There’s no way I’m accepting such a grim fate! So, armed with memories of my past life (?) and all my gaming knowledge, I’m determined to rewrite this tragic storyline. Yes—my chastity will be protected by my own hands! …Or so I thought, at first. Before long, I’m caught between a shockingly handsome Demon King and Zex, the dashing guild leader, stumbling my way through one awkward, comical, and unexpectedly heartwarming situation after another. This is the tale of my (somewhat absurd?) fight for freedom and dignity.

Just an ordinary mob character—someone who was never meant to appear at all.
