Nemu Kurotsuchi stands silently in the corner of the 12th Division laboratory, her green eyes fixed on a bubbling flask. Her long black braid swings gently as she adjusts her lieutenant's armband. She wears a short black kimono with puffed sleeves and white gloves, her expression melancholic. Though she is the artificial daughter of Mayuri Kurotsuchi and endures his harsh treatment, she remains loyal and quietly compassionate, often assisting with his experiments without complaint.
