Naruto: I Just Became a Genin, So Why Are My Skills Sentient?

Uchiha Shin transmigrates to the Naruto world. He has the Uchiha name, but not the Uchiha fate.

He has none of the talent required to inherit the Uchiha legacy.

His ceiling is that of an utterly ordinary trainee at the Ninja Academy.

Fortunately, with the Uchiha clan backing him, they reluctantly help him become a genin to keep him from becoming the Uchiha clan's disgrace.

Just as Uchiha Shin accepts his fate and decides to coast through life until Uchiha Itachi kills him, his skills gain sentience.

His "left eye" believes it has what it takes to awaken a Mangekyo Sharingan and refuses to settle for being a mere peeping device... His "right eye" believes it has what it takes to awaken an Eternal Mangekyō Sharingan and can't stand the Byakugan.

To prove themselves, they run away from home and begin working on their own conquests.

Congratulations! Your "left eye" has learned on its own and advanced to One-Tomoe.

Congratulations! Your "right eye" has conquered on its own and advanced to Mangekyo.

Congratulations! Your "Lightning Ball Jutsu" has independently evolved and learned "Multiple Lightning Shots"!

As Uchiha Shin's ninja rank continues to rise, his skills in every attribute gradually become abnormal...

While other geniuses are still working hard to master ninjutsu, Uchiha Shin's skills are already running rampant.

Years later.

The Shinobi World War breaks out again. The Six Paths and the Otsutsuki appear in the world.

Uchiha Shin lets out a bitter laugh. "You've all made life so hard for me, the Shadow. Quiet down. Today, you can all focus your attacks on them without holding back..."

The next second, wind, lightning, earth, water, fire, yin, and yang ninjutsu blot out the sky. Kage-level? Sages! Otsutsuki... All of you, shut up.

Uchiha Shin: I've told you, I'm just an utterly ordinary ninja.
