I was reincarnated as a random Uchiha in Naruto, oh hell nah I'm not gonna die I will do what ever I want and I WILL SURVIVE. Edit: It starts off a little bad but it gets better as it goes on. Like all stories.

After a tragic encounter with robbers, David, a devoted single father, finds himself unexpectedly transported into Jujutsu Kaisen. Now inhabiting the role of Seijuro Gojo-the mysterious, previously unmentioned father of Satoru Gojo-David possesses crucial knowledge of the events destined to unfold. Determined to defy fate, he sets out to rewrite the future: to ensure his survival, help his son, and save those marked by tragic endings. Facing powerful foes and navigating complex relationships, David must use every ounce of his wit and newfound powers to alter the path of destiny itself.

Waking up in the world of Naruto, I found myself transmigrated into one of the most tragic figures in shinobi history-Yagura Karatachi, the future Fourth Mizukage of the Hidden Mist Village. In the original timeline, Yagura was doomed to be completely controlled by Obito Uchiha's Genjutsu alongside his tailed beast, bringing unforgettable blood and tears to his own village. Is that fair? Is that logical? It's completely absurd! Fortunately, the Third Shinobi World War hasn't even begun yet. There is a saying that "No true ninja exists after the Pain Arc." Real ninjas shouldn't rely on red-eye bloodline cheats to summon giant energy Gundams to hack each other. More importantly-the ninja world is vast, and it revolves around far more than just Konoha! I, Yagura Karatachi, the Perfect Jinchuriki of the Three-Tails and the Fourth Mizukage, will never become a mindless puppet to be toyed with. I will never let the tragedy of the "Bloody Mist" repeat itself! From the secluded islands to the great continent, the Hidden Mist will forge its own path, crush the illusions of the gods, and stand at the absolute apex of the shinobi world!

Thanks for the invitation. I am currently in Konoha and have just become Orochimaru's apprentice. "So, is the Sharingan's transformation from one tomoe to two or three tomoe due to genetic mutation, or something else?" Staring at the restrained Uchiha test subject in front of him, Kenichi Amamiya's eyes shine with intense curiosity. Orochimaru silently accepts the thick stack of pages in his hand, titled "Research Report on the Impact of Soul Reincarnation on the Body." When Orochimaru receives a paper titled "Research Report on the Impact of Soul Reincarnation on the Body" from his disciple, only one thought crosses his mind: This kid is even more dangerous than I am.

Reborn in the world of Naruto, Kazane Hatake becomes the eldest son of the Hatake family and Kakashi's older brother. Armed with the legendary Three-Sword Style from Zoro, Eight Gates, and Haki, he carves his own path as a warrior, determined to protect his loved ones and bring lasting peace to the ninja world. As he faces powerful enemies-including the likes of Six Paths Madara, who acknowledges him as the strongest-Kazane pushes the limits of his strength, wielding techniques that defy reality itself. "Nine mountains and eight seas make up one world. A thousand worlds form a 'small thousand world.' Multiply that by three, and there is no self, no end-this is the essence of the Three-Sword Style!" But in a world where disaster strikes without warning, explanations won't save anyone. Strength is the only truth. If he falls, it will only mean he wasn't strong enough to begin with. With an invincible system and a mind as sharp as his blades, Kazane will shake the very foundations of the shinobi world!

A soul is reborn into the Zenin Clan of the Jujutsu Kaisen world, named Mukuro. Branded as useless under the influence of Heavenly Restriction and cursed fate, he is cast aside together with his elder brother, Toji, as so-called "failures" of the family. But is that truly the case? Naraka, Preta, Animal, Asura, Human and the Deva path-with the eyes of Six Paths of Reincarnation, Mukuro will rise to become the strongest. ••••••••••••••••••••••••••••••••••••••••••••• To read 26+ advance chapters and support me, visit my p@treon at - P@atreon/SilverShark769

(Sub: Ninja Scientist: Defeating Gods with Aerodynamics and Dust Explosions) "Don't hold us back, Tetsu," Fugaku Uchiha said, his Sharingan spinning with cold pity. "In this world, bloodlines are everything. A civilian like you should stay in the lab." I didn't argue. I just pushed up my glasses, calculated the precise air density, and flicked a handful of ordinary flour into the air. "In science, Fugaku, there are no miracles-only reactions." Ten seconds later, the invincible Uchiha fire-style met a massive Dust Explosion. As the smoke cleared, the genius finally understood: his eyes could track my movements, but they couldn't see the laws of physics. Transmigrated as Nishikawa Tetsu, a modern researcher in the brutal era of the Second Shinobi War, I have no bloodline and no system. All I have is a PhD-level understanding of the universe. While others waste chakra on flashy hand signs, I'm calculating muzzle velocity and fluid dynamics. From teaching Minato the aerodynamics behind the Rasengan to outfitting Konoha with weapons that make Susanoo look like a toy, I'm here to prove one thing: A railgun at Mach 7 doesn't care about your destiny. What to Expect: [Physics Over Bloodlines]: Dismantling S-rank Ninjutsu using high-school chemistry and advanced logic. [The Genius's Teacher]: Watch Minato and Fugaku go from "protecting the weakling" to asking for homework help. [Absolute Fix-It]: No Uchiha Massacre. No Minato's sacrifice. A high-burn, tactical survival story where science wins. [Smart MC]: No shouting for power-ups. Every victory is a calculated, brutal masterpiece of research.

Year 5 of Konoha. Hashirama was still alive, and the Nine-Tails had not yet been sealed. Toji, who specialized in medical ninjutsu, fled from Takigakure to Konohagakure carrying the secret art of Earth Grudge Fear. There, he became the hospital director and started living an easygoing life. As Hashirama Senju prepared to head toward the Valley of the End for his destined meeting, Toji calmly took out something he had long prepared. The Organ Donation Consent Form. "Hokage-sama, sign this before you go." ••••••••••••••••••••••••••••••••••••••••••••• I do not own anything related to Naruto.
