Traveling to the world of Naruto, he became a ninja, and was called the super genius Sasuke.
But on the first day, he encountered a murderous case by the Uchiha clan. Itachi discovered that Sasuke was not himself, so he let him go.
"Don't think that you can tell everyone the truth and get it over with. In this era, there are many people who can use you to achieve great things. Just live with the shame of the Uchiha clan. When you see the facts clearly, haha, I don't know if you can survive that day."
Itachi's warning frightened "Sasuke", but with low strength, he had to keep practicing in order to better survive in this world.
In fact, Orochimaru was not only interested in Sasuke, but also Naruto.
After the Battle of Konoha, Naruto, who was supposed to be accepted as Jiraiya's apprentice, unexpectedly surrendered to Orochimaru, leaving Sasuke at a loss.
This is definitely not the Naruto world in his eyes, but he knows that it will be crueler than the world in the comics.
If you don't kill, you will be killed!
This is a ninja!
