Naruto: The Uchiha Soul System

Waking as Uchiha Gen in the brutal heart of Naruto's Third Ninja War, this 13-year-old transmigrator faces a grim reality: certain death on the battlefield, the oppressive scrutiny of Konoha's elders, and the looming, dark fate of his Uchiha clan. His chances of survival are zero in a world built on blood and sacrifice, where loyalty often means a swift demise. But Gen didn't just inherit a Sharingan; he also gained the terrifying, game-changing power of the Soul-Soul Fruit! Now, every fallen enemy, every ninja's departed soul, fuels his ascent. He harvests their very life force, transforming ordinary kunai into loyal, auto-targeting weapons, and turning the very trees of the battlefield into deadly, sentient traps. As the Uchiha's dark, predetermined fate approaches, Gen must decide: will he bend to Konoha's will, or carve his own terrifying path to absolute power, leaving a trail of animated weapons and consumed souls in his wake? The true King of Souls has arrived, and the entire ninja world has no idea just how dangerous a weaponized soul can be.
