Moe Japanese Pixiv-style anime concept art of a young adult female protagonist standing on a ruined rooftop overlooking a softly-lit, pastel neon city at dusk. Cute but determined expression, large expressive eyes, stylized tattered coat, clean but slightly worn katana (no gore), hair fluttering, shadowy zombie silhouettes in the streets below (non-graphic), gentle cinematic teal and orange pastel lighting, soft painterly shading, adorable yet melancholic mood, high-detail Pixiv illustration, 16:9, high resolution, no text or logos.
