Nobody
In a room in the school, The room lights are not on. Suguru Anzai was listening to high-performance wiretaps placed in various places in the school, while watching the screen displaying images from multiple surveillance cameras.
"I see…the culprit is…"
"Hmmm, I guess you've reached me by now."
A voice that sounded certain came through the earbuds, and the mastermind couldn't help but smile.
"Oh, no. It’s wrong. I thought my reasoning earlier was perfect. I need to go back and rethink again."
A short time later, the culprit heard Shūhei Tsuchiura's voice again.
"I knew it. Even he wouldn't notice."
"I will…"
Suddenly, a new voice came from the earphones that were quiet.
Suguru Anzai listened intently.
"I will kill you too. I won’t forgive you. Even though we entrusted you with all of our feelings."
From the earphones came a low male voice.
"Who is it"
"That’s the best your head can do. Then I'm done with you. You're going to hell with us."
Suddenly, a loud road came from the wiretap.
Suguru Anzai's eyes widened.
"No way. He should be the only survivor by now."
Suguru Anzai quickly turned to a computer nearby and looked at the surveillance video.
The surveillance cameras were switched in the following order: school gate, cafeteria, entrance, library, first floor hallway, teacher's office, second floor hallway, third floor hallway, and principal's office, and finally the surveillance camera that captured the roof top projected Shūhei Tsuchiura.
"No way, is there really someone else?"
The culprit looked closely and saw a black shadow on the edge of the surveillance camera.
"Who? Who is it?"
Of course, Suguru Anzai's voice couldn't reach the rooftop. Yet, faced with this unforeseen situation, the mastermind couldn't help but speak out.
Shūhei Tsuchiura backed away as if being pursued by someone, then fell from the rooftop.
"What?"
There were no listening devices installed on the rooftop, so Anzai couldn't make heads or tails of the situation.
Suguru Anzai removed the earphones and clattered down the hallway and ran up the stairs leading to the rooftop.
When the murderer opened the door to the rooftop, the whole area smelled of death and harsh iron, which teased the culprit's nose.
Suguru Anzai, without regard to such things, went straight to the edge of the rooftop and looked down.
Shūhei Tsuchiura's body was there.
His limbs were bent in the wrong direction, as if every bone in his body was broken, and blood, a sign of life, was flowing out of his body in large quantities.
"What on the earth is happening…"
"I was waiting for you."
Suguru Anzai suddenly heard a familiar voice and turned around in surprise.
Shūhei Tsuchiura was standing in front of the mastermind. Looking down at his feet, both were properly attached to the ground.
"That was my clone."
"…"
"So shall we begin? With the final experiment of this series of game."
