Intro
Red stains your vision. Red. Red. Red. The screams of the crowd sound distant. Someone. Call an ambulance. Meen-meen-meen... the buzzing of cicadas pierces your ears. It's painfully loud, the sky is so blue, yet everything before you is dyed red.
No, please. Don't go. Don't leave me behind.
──August 13th. Senku Ishigami died.
Beep-beep-beep. Beep-beep-beep. You bolt upright. Your clothes are uncomfortably stuck to you with sweat. Was it a nightmare? A dream? It felt too real. Suppressing nausea, you turn off the alarm. The date written there is...
August 13th...?
