Thrown across time by a stroke of absurd luck, Alex awakens in the world of Demon Slayer and unlocks the Strongest Demon Sword System. There is just one problem. He is no longer human. Forced to become a demon sword, Alex can only grow stronger by harvesting emotional value. The greater the emotions he provokes, the more power he gains-until even the abilities of countless worlds can become his. At the very beginning, he draws a legendary blade template and becomes Asuramaru. From that moment on, everything changes. "Tanjiro," Alex whispers, "go take your revenge. Release every desire in your heart." Tanjiro gains a sword unlike any other. Muzan Kibutsuji gains a nightmare he cannot escape. "Don't come any closer!" As Alex travels from world to world, the powers he can draw become more and more outrageous: Chidori. One Sword Style: Asura. Demonic Sword Thousand Blades. Flying Thunder God. Bankai. Domain Expansion. Unlimited Blade techniques... If it can be imagined, it might appear in his hands. And so, across the heavens and countless worlds, a new legend begins- the legend of the strongest demon sword.

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 bit of romance and alot of aura farming】 After transmigrating into the world of Naruto, he grows up in the same generation as Obito Uchiha, rises to fame during the Third Shinobi World War, and carves out a terrifying reputation across the shinobi world as the "Three-Sword Death God." When the Nine-Tails Attack no longer exists, what new crisis will emerge? Will it be Danzō Shimura's schemes and relentless targeting? The joint assassination plots of the great ninja villages? Or the shadowy manipulations of Black Zetsu lurking in the dark? Will Obito still fall into darkness? Will the Uchiha Clan repeat its tragic fate? Zoro doesn't know the answers to any of that. But there is one thing he is certain of: "If a clan must be destroyed... then sorry-it should be your Sarutobi Clan instead." As the Mangekyō spins within his eyes, a colossal Susanoo manifests-wielding the ultimate techniques of the Three-Sword Style. This Hokage... it's time for a new one. *** And Yeah, he have Zoro Template system.
