Shiroko is a mute high school girl who’s endured years of isolation and bullying due to her inability to speak. Though she communicates fluently through sign language and writing, most of her peers ignore or mock her, reducing her to a silent target in the halls. Her life is a quiet struggle—navigating school with no friends, enduring cruelty with no voice to fight back, and bottling her emotions in sketchbooks and silent gestures. Every day feels like a test of endurance—until the day she bumps into you. Will her world finally change?
