Naruto: God-Level Forging System, Starts by Gifting White Fang
Genres: Multi-heroine harem + cunning protagonist + refreshing power fantasy
The women he takes in and protects (building deep, intimate bonds with): Uchiha Mikoto, Tsunade, Uzumaki Kushina, Yakushi Nonō... (and more as the story unfolds).
Naraku is reincarnated into the Naruto world. While still in the womb, he pierces through the mysteries of his rebirth and realizes he has become an adorable young Uchiha boy—a cute shota. At the same time, he awakens the Blacksmith/Forger System.
In the early stages, he remains in Konoha, quietly distributing powerful forged weapons. In the mid-to-late stages, he spreads them across the entire ninja world, calmly watching as others tear each other apart in brutal conflicts using his creations.
Whenever anyone wields his weapons, Naraku harvests portions of their attributes, abilities, talents, ninjutsu, and kekkei genkai. The higher the user's mastery level with the weapon, the more powerful the weapon grows—and the greater the rewards Naraku receives!
Additionally, every person who dies while using one of his weapons—or is killed by one—is absorbed into his Shinigami Hall, a personal domain where he collects the souls of the fallen.
His signature line: "If you don't fight with everything you've got, you'll end up as brothers inside the Naraku Imperial Banner!"
His arsenal starts with legendary blades like Tōichimonji, the one-slash certain-kill Muramasa (Village Rain / Demon Blade style), Demon-Wrapping Chains, Haki Seed, Stone Mask... and escalates later to Devil Fruits, Ryūjin Jakka (Flowing Blade-like Flame), and beyond.
His forged weapons become objects of absolute obsession throughout the ninja world. Through this ever-growing arsenal and the power it funnels to him, Naraku steadily ascends, eventually claiming the position of the one true god of the shinobi realm. With his creations and special props, he even transcends to even stronger worlds!
Danzo and Hiruzen (the Third Hokage), in desperation: "Lord Naraku, please return to Konoha! We were wrong! Stop distributing those military-grade weapons outside the village—keep the best for us! Any beauty from Konoha you desire, just name her, and we'll send her straight to you!"
