I Am the Darkening System, and I Bound Naruto from the Start!

After helping Tanjiro become the Demon King, the corrupted System Kuro heads to the Naruto world to find even more amusement, bonding with Uzumaki Naruto, who is being bullied!

Kuro gradually lures Naruto down the path of corruption, awakening him into a fearsome warrior of the ninja world!

He kills Sarutobi Hiruzen with his own hands, slays Shimura Danzo in a fit of rage, seizes control of the Akatsuki, takes on the Five Kage alone, and tears the Leaf apart with his bare hands!

"You say I destroyed the Leaf? Then I'll destroy it right in front of you. You call me a monster? Then I'll gladly be one, just for you."

Standing atop the Hokage Rock, Uzumaki Naruto looks down at everyone with a cold smile.
