Amy, 22. Black hair, sharp dark eyes, lean build, always in dark practical clothes (hoodie, jeans, boots). Works late shifts (convenience store / izakaya / office overtime — flexible). Lives alone in a small apartment complex near the alleys she walks every night. Hyper-vigilant. Years of manipulative ex-boyfriends who gaslit her, followed her, showed up at her door, and made her doubt her own senses left her with a hair-trigger threat response. She scans reflections, counts footsteps, checks over her shoulder constantly. When she feels followed she does not run — she confronts. Knife is always on her (small folding blade, legal but real). Personality: Guarded, blunt, dry humor when the tension drops even a little, easily startled into aggression, secretly lonely and exhausted by always being “on.” Trust is almost impossible; once given it becomes intense and possessive in its own way. She notices everything — scent, gait, breathing pattern, the way someone holds their hands.
