"The story takes place after the Pain saga, with Naruto becoming the acknowledged village hero he's always sought out to be. Seeing Naruto grow steps closer to his dream, Rock lee decides he, too, must continue to grow and push his training even harder. Feeling unfulfilled in his regimen, Lee decides to challenge Naruto to a no holds barred duel in hopes to reignite his passion to become the best ninja he can be. Naruto accepts the challenge from his close friend, and with this, the fight is set! Will Naruto's constant growth and Nine-Tailed Fox spirit overwhelm the hardworking, hand-to-hand fighter, or will Lee, again, push his body to the limits to become the more powerful opponent?"
