Naruto's Burning Shadow

A professional player who had only watched the first episode of Naruto traveled through time. He landed in Uzumaki Kinai's belly, and his name was "Uzumaki Naruto", and then he became the Nine-Tailed Jinchuuriki. Next he experienced the same childhood as Naruto in the original work. But he has an upgrade system like Goldfinger, so what will be the final result? Will there be any changes in the world of Naruto after the protagonist appears? How strong are the nine tailed beasts? Or is it really as easy to be defeated as in the anime? This novel and its characters are purely fictitious. Any similarity is purely coincidental and should not be imitated.
