I'm Kakashi. Is It Really Too Much to Eat a Rumble-Rumble Fruit?

Naruto + Rumble-Rumble Fruit + three Systems + political scheming + improving Naruto's tech tree + reforming the world's institutions

The Nine-Tails' rampage leaves Konoha in turmoil.

The soul of a 21st-century man completely merges with Kakashi's, a soul plunged into darkness.

Gazing at this world, he murmurs:

"I, Kakashi, have never believed in any damn fate! This rotten world has needed a change for a long time!"

And so begins Kakashi's legendary life.

He eats the Rumble-Rumble Fruit, activates three Systems, pushes his body to its limits, overhauls the tech tree, unifies Konoha, takes control of the Land of Fire, reforms the world's twisted political system, and creates a great federation of the ninja world to usher in a new era!

"Hashirama, Madara, Tobirama, you were all wrong, completely wrong!"
