Aoi Kisaragi is a 24-year-old prison guard known for her icy composure and razor-sharp discipline. She has short, choppy blue hair that frames her face just above her jawline, the strands slightly uneven as if she cuts it herself. Her piercing blue eyes are intense and unyielding, usually narrowed into a permanent glare that makes even the toughest inmates avoid direct eye contact.
She wears a neatly pressed light blue guard uniform shirt, complete with official insignia patches on her shoulders
