He just traveled through time and became an orphan in Konoha. Before he could plan his life, he was dragged into a dark interrogation room by the "root" ninjas.
As the torture intensifies, the [Absolute Truth System] awakens!
Everything I ask is true!
I thought I could survive on it, but I didn't expect that the first question would detonate the entire Konoha!
"Danzo, is that Sharingan of yours Uchiha Shisui's?"
"The Third Hokage, are you really unaware of the Uchiha genocide?"
"Kakashi, Obito... Do you really think he's dead?"
When the hidden truths were revealed by me in public, the entire ninja world went crazy.
I, Light Yagami, will either become the public enemy of the ninja world, or... I will become the truth itself!
