Death Note: I Stole Kira's Spotlight from the Start

After transmigrating into the world of Death Note, I become the youngest criminal investigator in the Tokyo Metropolitan Police Department. The story begins seven days before Light Yagami gets the Death Note. I know every move Kira will make, I'm familiar with all of L's plans, and the Death Note's thirteen rules are etched into my bones. But I know that an all-knowing God's-eye view is the deadliest poison in this world.
