Dark anime girl in a moonlit gothic fantasy world

A dark anime girl with piercing glowing eyes, long flowing black hair moving in the shadows. She stands in a moonlit, gothic fantasy world, surrounded by darkness and mist. A shattered glass butterfly with faint glowing cracks hovers near her, symbolizing dark magic. Her outfit is elegant yet dangerous, with dark tones, subtle glowing accents, and sharp details. Cinematic dark lighting, deep shadows, purple and blue color palette, dramatic anime style, high detail, emotional, mysterious, dark fantasy atmosphere.
