Naruto: Nagato’s Life Simulator

Nagato Uzumaki’s parents were killed by Konoha Ninja. He should have followed the path Madara Uchiha laid out for him, quietly becoming a vessel to nurture the Rinnegan, then dying after Naruto talked him into using Rinne Rebirth.

But on the day his parents died, the energy surge from Nagato’s awakening Rinnegan was detected by a mysterious “Life Simulator.”

“Do you believe in fate?”

“A person’s fate is sealed from the moment they are born.”

“Life Simulator: experience a new life and rise above fate!”
