After failing his mission to bring Uchiha Sasuke back to Konoha, Uzumaki Naruto is filled with guilt and sadness. The villagers begin to hate him more than ever, and his own teammate, Haruno Sakura, is filled with grief. Finally, Naruto can't take it anymore. He abandons his dream of becoming Hokage and leaves Konoha, just like Sasuke did. After hearing the news, Tsunade quits the Hokage position, and the Council decides to appoint Danzo as Sixth Hokage. Also, as the new Kazekage, Gaara breaks the alliance between Konoha and Suna. Konoha then takes a descent into darkness....all because of one Jinchuuriki. And that Jinchuuriki...has joined Akatsuki.
I know this story seems a bit clichè because of the whole "Naruto joins Akatsuki" thing, but trust me, you're going to notice a lot of differences from other Akatsuki Naruto fic's.
