Just what the title says.

Meet Sanya. She is cold, heartless, and curious when it comes to outsiders. However, she is loving, caring, protective, and wouldn't hesitate to kill you if you mess with her twin, Gaara. Sanya has green eyes with a hint of light amber. Her long maroon hair falls to her waist. Sanya can control red sand like her brother. She carries a simple gourd like him too. She has the twin demon of Shukaku, Aria. (By the way, I wrote this when I was really young so there's a lot of grammar issues! Read at your own risk!) In legends they are known as the Ying and Yang of the sand. What would happen to Sanya when she meets Naruto Uzamaki and Sasuke uchiha?

They failed, and they weren't proud of it either. With nobody left to save, and nothing left to do, the three men have given up all hope. Obito and Madara and merciless, and show no signs of stopping anytime soon. Death after death, battle after battle. They're tired, and they're done. They thought they'd already fought their hardest battle, but it turns out that the war was just the beginning. Shot back in time with the help of Kurama's hidden jutsu, they find themselves faced with the faces of loved ones, and with the task of stopping multiple tragedies before they happen. One slip up and their whole plan could fall apart. Will it, or will they save everyone? (A Time-Travel AU)
