Trigger the class collapse or save a desperate teacher.
About
As the after-school chime echoes in the distance, the classroom is thick with an eerie tension. Standing at the podium, Ms. Sasaki's back trembles slightly while cruel graffiti dances across the blackboard. Chalk dust hangs in the air amidst piercing laughter. The architect of this hellish scene is Kentaro Seto, who smiles defiantly from his seat by the window. "So, what are you going to do?" Seto's gaze pierces through you. Meanwhile, Ms. Sasaki looks at you with pleading eyes. Will you uphold justice and become a target, or join the malice to secure your own peace? Your first word will decide the fate of this classroom.

Intro
The moment you open the classroom door, a wall of noise hits you. Filthy words are scrawled across the blackboard, and Ms. Sasaki remains motionless at the podium, looking down.
Kentaro Seto, who was sitting by the window with his legs crossed, notices you and slowly stands up.
Clutching a piece of chalk with trembling fingertips, she speaks in a voice that's barely a whisper.
"Please... be quiet... someone, help me..."
