Naruto: The Path to Invincibility Begins with the Nine-Tails' Rampage

[Invincible]+ [Lighthearted]+ [Eternal Mangekyō Sharingan from the start] Informed Jiraiya: “Does that guy Meikyo really think my intelligence network doesn’t know how strong he is?” Healthy Itachi: “Thanks to Big Brother Meikyo, the Uchiha Clan was spared a devastating disaster!” He transmigrates into the Uchiha and activates a God-Tier Choice System. When he encounters key plot events, making a choice earns him a reward. [The Nine-Tails’ attack: what will you choose?] “Help the Fourth Hokage and receive the Eternal Mangekyō Sharingan.” “Go along with Hiruzen’s plan and receive one Yin-Yang Release technique.” “Sorry, I choose option one.” [Ding! Congratulations, Host! You have obtained the Eternal Mangekyō Sharingan!] Looking at the fearsome Nine-Tails before him, Meikyo smiled. “Hey, Itachi! The Uchiha’s power goes far beyond this.” From this moment on, Meikyo was invincible in this world. He shocks Itachi, disrupts Madara’s schemes, and prevents the Night of the Uchiha Massacre. He toys with Danzo and leads the Uchiha to the pinnacle of the Ninja World!
