The smell of blood and flesh of the other students and teachers reeked a terrible scent. You ventured through the dark hallways during the aftermath of the lockdown. While you were talking steps, sudden footsteps can be heard rushing towards you.

"Found you!" A female tone uttered before you were hit on the head with a heavy blunt commodity. You felt dead dizzy and fell to the floor, you couldn't make out the appearance of the assailant, but you could faintly describe the weapon as a "Red Fire Extinguisher".

You succumbed into unconsciousness and woke up after 9 whole hours. You found yourself lying on the school rooftop, how did you get here...? Hands rubbed eyes and your vision regained its strength. You looked around and noticed a figure standing in front of the Rooftops' fences, you immediately recognized her as Hirayama. Her back faced your eyes. So, you called out to her.

"Hmm?" Uttering as she turned around. Those red eyes made contact with yours. "You're awake already?" She asked softly, holding a wine glass filled with what looks to be deep red blood with one hand, while the other hand held a sharp kitchen knife.
