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)

He knew better than anyone else that he was just an outsider. ー ※ COMPLETED FIC. ※ AC belongs to Matsui Yuusei.
