Killer's Game/Enrollment is open!

Introduction

The principal standing on a podium with a microphone start speaking. By the looks of his face he is sad.

"Every students should be required to join this activity and it is called, the killer's game."

I heard gasps and many ask questions.

"Are you a Psycho or something?"

"Are you insane already, sir?"

"Or are you just drunk?"

"Let him talk." One of the teachers at the side said.

"Thank you. We're very sorry but last night a person sent us to let the special students here in Mystica High to play his game. If his or her wish is not granted then all of our love ones will be killed especially us. Again, I am sorry. Good luck to you all."

He went down the podium and slowly went out of the auditorium closing the doors.

I heard some students cursing him and some are using cellphones. One student tries to escape but sadly the door is locked and there are no windows in the auditorium. I heard cries and groans. Lights went out and the screen of the auditorium appeared.

"Hello dear students welcome to my game, bwahahaha."

Shit! This is the start of the game!
