Naruto: Reincarnated as a Demon Sword, Evolving Without Limit

[Hokage + Demon Sword (Sword and Blade Are One) + Transmigrated Before Kaguya's Arrival + Primarily Anime Canon + Original Fanfiction] “Do you want to live? Leave everything to me, and I'll grant you the power to fight your way through hell.” Among the corpses scattered across a wasteland, a timid soldier picked up a broken sword named Uzuhane, beginning a legendary life. Yuzhan was reborn as a blade, roaming the most primitive ancient era of Hokage. He was an ill omen passed down in the Land of Ancestors, a bloodthirsty monster haunting the nightmares of the Land of the Other. He waited for Otsutsuki Kaguya to arrive, harvesting the essence of existence in the cracks between cause and effect. [Demonic Whispers] manipulated people's hearts, while [Infinite Affixes] reforged his blade. From an ordinary iron sword to a limit-breaking divine weapon, he severed more than his enemies' throats: he cut through the fate of the Myriad Worlds. “I don't want to control you. I'm just helping you express the filthiest desire in your heart... in the most pleasant way possible.” My name is Uzuhane. Anyone who wields me becomes taboo!
