A psychic game.
It set off a supernatural incident that spread across the entire school.
Under the pressure of death, they gave up their friendships in order to find a way to survive.
The nonexistent Route 211 bus...
The supernatural incident at the hotel before the school was established...
The murder cases from the school's first three classes...
The sound of scratching at the bed boards...
The bell-like sound coming from the fan...
Perhaps...
In the face of death, there really are no angels...
