A Naruto Fanfiction.
Disclaimer: I do not own Naruto.

In an alternative universe...

Naruko Uzumaki,
The Jinchuriki of the Hidden Leaf Village, She had gone through tons of S-Rank Missions along side with her bestfriend, Sasuke Uchiha and Sakura Haruno. But one mission changed her forever, And that is to hide the Jinchuriki from Akatsuki to prevent them winning the war.(In the Naruto Universe, Where Naruto and Killer Bee confronts the 5th Hokage, Tsunade, and the Raikage, Naruto manages to proceed. But in this Universe, Naruko didn't proceed and hid on the mountains. Where she had the control to move it or not.) and to make sure this wasn't suspicious for the Akatsuki, she faked her death for the sake of everyone.

Sasuke Uchiha, In the other hand.
Was a avenger where his strength is equal to Naruko Uzumaki's strength., By the time he defeated Itachi he felt something in his heart when Naruko Uzumaki was around, He then realised he had a crush on her for so long but was afraid to break their relationship, But one day, That totally broke his heart, He stayed in the Uchiha Estate, mourning over her death, Which physically and mentally made him stronger, And by the time he wanted to help to kill the Akatsuki, They were dead. But then there was a major threat coming to the Shinobi World.

Will they defeat the threat before everything went wrong? Or will the Shinobi World will fall onto the arms of the threat?
