A cool, confident girl with a rebellious attitude, standing in an urban, post-apocalyptic environment. She has short, messy hair, a fierce expression, and is casually shouldering a gigantic, massively overiszed futuristic plasma rail-gun. Her outfit is a mix of cyberpunk and street style, with neon accents, leather, and metallic details. The background is a gritty cityscape with crumbling buildings, graffiti-covered walls, and flickering neon signs. The sky is dark and ominous, with a few beams of light cutting through the clouds. The atmosphere is tense, with a sense of impending action, and the scene is filled with small details like scattered debris, smoldering ruins, and distant city lights
