Naruto: So I Edited Everyone's Memories. The Ninja World is Mine Now.

[Plot-Driven + Brainstorm + Capturing Tailed Beasts] Sanri Qianhuan had transmigrated—and he soon realized that not only had he come alone, but he'd also brought a "gift" for the entire ninja world. A memory of a "past life." In this memory, he was the "Sanri Qianhuan" who had ended the age of chaos and unified the ninja world. Hiruzen Sarutobi recalled the terror of being turned into a lampwick and resigned overnight. Danzo Shimura remembered the humiliation of being paraded through the streets and disbanded the Foundation. Fugaku Uchiha remembered the despair of having his wife offered as a sacrifice and passed the clan head position to Itachi. And Itachi Uchiha remembered the "Emperor" who had given him dignity and power. When everyone believed this "tyrant" had returned for revenge— Sanri Qianhuan was holding up a wanted poster, trying desperately to explain to Konoha's higher-ups: "Uh… I was framed. I'm really not some kind of First Emperor." No one listened. Because Itachi Uchiha was already charging in with his Eternal Mangekyō. "Anyone who dares touch the Emperor—I'll wipe out their entire clan." Sanri Qianhuan looked at this five-or-six-year-old "god of death" and let out a helpless sigh. Since history has already gone off the rails— Then let me, this "fake Emperor," bring true peace to the ninja world. "Spread the word—starting tomorrow, Konoha will implement nine years of compulsory education."
