[Naruto + System + livestreaming + power fantasy + mind games]
I transmigrated into Naruto and became an unnamed, expendable genin.
Then, in the Forest of Death, the System awakened. I could replay any history that had been buried.
I watched the tormented Sasuke Uchiha and sent him an edited clip of the night his clan was massacred.
Sasuke went berserk, Kakashi was stunned, and the Third Hokage summoned me to the Anbu that very night.
Later
Before Pain attacked Konoha, I replayed “The Death of a Dear Friend” for him;
Before Uchiha Itachi met Sasuke, I queued up “The Konoha High Command Meeting: Full Recording” for him;
During the Fourth Shinobi World War, I played on an endless loop for the entire shinobi world: “Princess Kaguya's Postpartum Care and Black Zetsu's Filial Devotion.”
When the Ōtsutsuki Main Family arrived, they saw the even more ancient “The Mystery of Chakra's Origins” in my hands.
They fell silent.
I pressed play. “Welcome to ‘The Ōtsutsuki Family's History of Scandalous Relations.’”
