Naruto with Pocket Hunting Dimension Cheat.

In the future of the ninja world...
The greatest clan in the lower dimension, known as Horoyoma, was said to have been destroyed as a result of Naruto's actions and his family history. The parent clan of the Otsutsuki and the most feared clan in the lower dimension.
Hence...
The strongest warrior of their clan was sent to kill Naruto when he was at the beginning of his journey, but the time itself was a strange enigma and was saving Naruto from dying in that timeline, so the warrior had a little time to kill Naruto's child self.

During that battle, Naruto's soul was shattered and the karma in that location was disintegrating when an enigma brought on by this distortion reemerged in the Naruto universe.

It was the moment when this world was about to welcome a brand-new character. With the world Karma's wrath upon him, this youngster's destiny was set on raising this lower world and destroying the largest clan in order to usher in a new era.
