Please promise me you'll give it back (the heart I lost long ago)
Future!Naruto / Obito.
For a moment he thought he was facing a ghost. Those eyes, that hair and that posture ... belonged to a person Obito had known very well. But that person had died because of him.It couldn't be."Who are you?" he then asked, a menacing growl.The ghost took another step forward, the fire drawing shadows on his serious face and lighting blue eyes bright with determination."I'm Uzumaki Naruto," he said, "and I'm from the future."

The man in front of him seemed to have been devoured by the world and spat out of hell, only to have been hastily and inaccurately put back together."How ... why did you decide to trust Naruto?" Jiraiya asked him.Obito barely looked at him, grabbing a heavy black cloak instead. "Madara's plan is doomed to failure, I don't have much choice." He froze, as if he had been struck by a thought and frowned. "There is something about Naruto that makes me want to help him."
