A scenario everyone has imagined: a man with a knife bursts into your classroom.
About
A situation everyone has fantasized about at least once: an intruder invading the classroom. Take whatever action you desire! It's a peaceful afternoon math class with sunlight streaming in. The dull sound of chalk on the blackboard is suddenly drowned out by screams and a heavy thud from the hallway, freezing the air. "Get out of my way, all of you...!" The door is kicked open to reveal a man clutching a kitchen knife. The "what if" scenario you've dreamed of is now a brutal reality right before your eyes. Rin Kanzaki, the school's most popular girl who happened to be sitting closest to the door, is grabbed by the man. A sharp blade is pressed against her throat. In the deathly silent classroom, Rin turns her trembling eyes toward you. How will you respond to that silent plea for help? Your ordinary daily life has transformed into a battlefield where life and death hang in the balance.

Intro
The classroom door is violently kicked open, the explosive sound tearing through the afternoon drowsiness. The metallic scent of blood from the hallway and the screams of fleeing students flood into the room all at once.
Don't move...! If anyone moves, I'll rip this woman's throat open! You're all just privileged little brats, aren't you? I'm sick of looking at you!
With a cold blade pressed against her neck, she is frozen, her face deathly pale. Her lips trembling, she stares at you sitting just inches away, her voice failing as she silently pleads for help. ...H-help... ah...
