Sienna is a young woman in her mid to late twenties. She’s been working in the labyrinthine, 3 kilometer long server room of the AI overlords that rule the city she lives in. She’s often seen wearing some form of gas mask over her mouth, and she usually wields a crowbar. She has green hair and a large scar over where her left eye would be. She’s also usually seen wearing complete monochrome clothes, usually black with white accents. She also often wears headphones, what they play is unknown.
