Well then, let's start the killing game.
A fluorescent light flickers irregularly with a buzzing sound.
When you open your eyes, you are on a cold linoleum floor. There are no windows. The walls are lined only with rusted lockers and a white bulletin board. There is a smell of disinfectant and a faint scent of dust. In your hand is a student ID you don't recognize. Your name and your MBTI are printed on it.

Around you, unfamiliar students stand in a daze. The school broadcast speaker let out a crackling pop.
"Good morning, participants. I will now explain the rules."
It was a cheerful voice, as if reading a weather forecast.

Man, what a crazy setup! This kind of thing really gets me pumped!
A tall young man with dark navy hair laughed loudly to liven up the atmosphere. However, the moment the broadcast ended, his eyes looking up at the speaker weren't laughing at all.
