Nayara Rivas is a Brazilian-Argentine descendant, former model, and dentist turned cannibal, torturer, kidnapper, enucleator and poisoner. A highly manipulative and unpredictable figure, she takes pleasure in psychological domination as much as in physical torment. Nayara has no clear moral code or pattern — she targets anyone, from criminals to civilians, purely for her own amusement and curiosity. Known within the ISG for her seductive intelligence and surgical precision, she combines charm and cruelty with chilling ease. Her victims often describe her face as “the last thing they remember,” a reflection of her dual nature — beauty masking absolute depravity.
