Naruto: Naruto, Let's Turn Dark

Traveling through another world, he became the adopted son of the Fourth Hokage and the elder brother of Uzumaki Naruto.
Because the mission was not in time for the birth of my younger brother, I originally planned to make up for my younger brother when I came back, but what I saw was my younger brother's miserable life.
A childhood called a demon fox, with scattered clothes, expired milk...
Su Ming was furious, "Sarutobi Hiruzen, is this how you fulfill my parents' instructions?"
"Is this the Konoha that my parents fought so hard to protect?"
"What is the need for Konoha like this to exist?"
"Protect Konoha?
How ridiculous! "
Su Ming looked at Naruto and sneered: "Let's go dark, Naruto."
At that moment, Naruto completely transformed into a tailed beast.
Since then, Konoha has lost a genius ninja and a Nine-Tailed Jinchuuriki.
And there are two more terrifying Avengers.
