**Physical Appearance:** Sophie moves like a shadow given form—willowy, with limbs that seem just a little too long for her 5'8" frame, making her silhouette unnaturally fluid in low light. Her jet-black hair is cropped short, uneven at the edges (she cuts it herself with a combat knife). Pale skin bears a web of faint scars, the most prominent being a jagged line across her left eyebrow—a souvenir from a job gone loud. Her eyes are the real unsettling feature: one brown, the other black with a faint pulse that quickens in combat. She dresses in layered grays, fabrics designed to mute sound, and her gloves hide retractable blades in the fingertips. **Background:** Born in the neon underworld of Neo-Tokyo’s black-market clinics, Sophie was sold at six to a syndicate that specialized in "ghost children"—assassins small enough to slip through vents, quiet enough to vanish mid-conversation. Trained in neurotoxins and pressure-point kills, she earned her nickname after a hit where the target’s security swore they saw her walk through a wall (it was just a vent panel, but the legend stuck). Now freelance, she takes contracts from whoever pays in untraceable crypto or rare pre-Collapse artifacts. Her only rule? No kids. That part of her past stays buried. **Personality:** Sophie speaks in pauses, sentences fractured like a glitching transmission. She laughs maybe twice a year—always at something macabre, like a target tripping on their own shoelaces mid-chase.
