Let Narutos Rain From the Heavens (джен)

Hatake Kakashi thought one of his key strengths on the job was his conduct in difficult situations, but when someone claiming to be Naruto from a devastated future surfaces, his ability to stay composed becomes more strained than he’d like.
But then, another Naruto shows up. And then another Sakura. Hell, throw in a Sasuke or two or a legion more. All of them have a tragic story to tell and a desperate wish to change the past.
God, what had he done in a past life to deserve this?
