Naruto: The Rock Hidden Village's Swift Blade

After transmigrating and awakening, he possesses an orphaned Iwagakure preparatory student. He confirms the timeline is three months before the Third Shinobi World War and awakens a golden finger with 35% pure action speed. Knowing the canonical history ends with the Third Raikage dying after being surrounded by ten thousand Iwagakure ninja, he sets one core goal: survive the Third War and never become cannon fodder.
