The Rebirth of Killer Seven: Shadows of the Uchiha

At the age of six, Ryuji Uchiha began his training at the academy alongside the future Legendary Sannin—Jiraiya, Orochimaru, and Tsunade. They were young, barely more than children themselves, but they showed promise, each destined for greatness. But while the Sannin had the eyes of the village, Ryuji was different.

He learned quickly. He was sharp, far sharper than any of the other children, even the other Uchiha. His mind moved faster than his body could, and soon he was mastering the Fire Style techniques at a speed that would make even the elder Uchiha proud. Yet, his ability was not merely limited to ninjutsu. In the dead of night, away from the watchful eyes of the academy, Ryuji began to hone his combat skills, training with the sacred weapons of his past life—The Thousand Demon Daggers.

The Thousand Demon Daggers: The Thousand Demon Daggers were a set of cursed, razor-sharp blades, each infused with dark chakra from a world far removed from the world of the shinobi. The weapons were originally designed to assassinate even the strongest of enemies. Ryuji's past life as Killer Seven meant these weapons were his primary tools, each one deadly in its own right. They could slice through flesh and bone, and each dagger had a unique ability. Some could return to their master's hand when thrown, while others could emit deadly poison, or even transform into blades of pure chakra.

One night, in the secluded training grounds hidden deep in the Uchiha compound, Ryuji practiced the art of throwing these daggers. Each throw was clean, precise, and deadly. He could already feel the chakra flowing through the blades, merging with his own chakra, enhancing the effects of his attacks.
