  • 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!

  • What would you do if you woke up in the world of One Piece? Join the Marines? Yeah, right. Without powerful backing and connections, you’re just another pawn for the World Government; disposable in war, expendable in politics. I may be a total newbie when it comes to that kind of game, but I know enough to stay out of that mess. Become a pirate, then? Now that’s got potential. But Admirals are absolute monsters. And it’s not like I’m chasing the Pirate King title or looking to spark some grand revolution; I just want to live free, y’know? So here’s the game plan: Step one, become a pirate. Step two, get strong. Step three, earn a seat among the Seven Warlords of the Sea. Simple? Not even close. But it's the best shot I’ve got. Soka soka… Wait, author-san... when exactly do I get isekai’d? ——————— PATREON LINK: https://www.patreon.com/juanfiction 100+ advance chapter!

  • The skylark, a bird known for its ability to sing while flying, has long been regarded as a symbol of "freedom and peace." I was born into the prestigious Senju clan in the shinobi world, and my ojiisan, Senju Tobirama, the "Shinobi World's Fastest," named me Senju Hibari. I was the fledgling of the Senju family. Actually, all of this was an accident. My ride was originally supposed to take me to the neighboring world of One Piece, but the driver took a wrong turn, and that's how I ended up in this world. Fortunately, this world is quite interesting. When I have nothing to do, I can research Kinjutsu with my Ojiisan. I can also drag my good friend, Orochimaru, along to tinker with all sorts of bizarre scientific experiments. And whenever I have a moment, I can even discuss the creation of "Paradise Series" novels with the future Toad Sage. Life is pretty good. As for whether I have a cheat ability? Isn't that obvious? How could I, as a protagonist, not have the standard equipment? I could... ------------------------------- PATREON LINK: https://www.patreon.com/primaldemon 100+ advance chapters!

  • 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!

  • 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.
