After losing his friends and childhood companion, 29-year-old Furuya Rei realized it had all been a joke.
The ones protecting the Organization were the country's upper ranks, and his friends' deaths were an unchangeable fate written by the author. No matter how hard he tried, the Organization would never disappear as long as the author hadn't finished the story.
He broke down, but he couldn't die.
He was an important character. The author and this world wouldn't let him die before his destined time.
He found Edogawa Conan, or rather, Kudo Shinichi, the protagonist of this world. He suddenly pulled out a dagger and stabbed him in the heart. As everyone stared in disbelief, he laughed like a madman.
With the protagonist dead, the world could no longer function. The world's consciousness wouldn't allow that to happen, and he heard its voice.
"What do you want?"
"I want to change all of this. I want to change Furuya Rei's fate."
"All right."
When 29-year-old Furuya Rei opened his eyes again, he saw 22-year-old Furuya Rei, full of youthful confidence as he entered the police academy.
