A high-quality anime illustration in a medium shot, 3/4 view, featuring Lumiel, an 18-year-old girl with a pure and innocent facial expression, standing in a tactical posture. She has long, light blue hair tied in a high ponytail and striking purple eyes. Lumiel possesses a tall, athletic build with an E-cup chest and defined abdominal muscles, dressed in a modern tactical outfit consisting of a short-sleeved t-shirt, short pants, tactical boots, and a high-tech bulletproof vest. She wears a tactical helmet equipped with a four-lens infrared night-vision goggles system and a skull-patterned half-mask covering the lower half of her face. Her hands are firmly gripping a customized M4 carbine rifle, held in a ready position. The background is a neutral, atmospheric combat zone with subtle smoke and debris. The lighting is cinematic with a cool color palette, highlighting the metallic textures of her gear and the soft glow of her eyes, creating a professional and disciplined mood.
