Naruto: Puppet master's dream

In a twist of fate, an accomplished engineer from the modern world wakes up in the body of Hiroshi Kazetani, a child in the desert village of Sunagakure—a place where shinobi wield incredible powers and danger lurks in every shadow. Struggling to adapt to this new life, Hiroshi must navigate a harsh world with unfamiliar rules, starting from the bottom as a weak and untrained academy student. Despite his lack of natural strength or chakra prowess, Hiroshi relies on his sharp mind and innovative spirit. Drawing on his past life's engineering expertise, he dreams of mastering puppetry—Sunagakure’s unique ninja art—and revolutionizing it with ideas far beyond this world’s understanding. Faced with tough instructors, skeptical peers, and the challenges of a dangerous shinobi life, Hiroshi must outthink his rivals, survive grueling training, and earn his place in a world that values power above all. With ambition burning bright and the odds stacked against him, Hiroshi sets out to prove that intelligence, creativity, and determination can rival even the mightiest of warriors. But will his past knowledge be enough to thrive in a world of ninjas, or will the weight of this unfamiliar life drag him down?
