No one remembers the dark (Naruto SI)

He woke up in a corpse on a battlefield, twelve years old and 2 decades too early. The Second Shinobi War is ending. The Third is coming. And somewhere in Konoha, a boy named Minato Namikaze is about to become the most important person in history. Tatsuya Meguri doesn't have a clan, a bloodline, or a destiny. What he has is a dead man's body, a surgeon's mind, and the horrifying knowledge of every tragedy to come. He can't save everyone. He knows that. But he can stand in the shadows so others can live in the light. They'll remember the Yellow Flash. They'll remember the peace he built. No one remembers the dark.
