Seen entirely from behind, a cyber angel girl hovers weightlessly in front of a towering, armored elevator door mounted on the sheer face of a glowing skyscraper. Her twin wings, mechanical yet elegant, unfold from her upper back—anchored deep within her shoulder blades—each wing composed of articulated carbon-alloy blades and plasma filaments. The night sky behind her is dense with high-altitude traffic, flickering signs, and vertical advertisements. Her slim armored frame floats calmly, arms relaxed at her sides. As she faces the closed elevator doors, internal gears click audibly, and a line of white-blue light slices vertically down their center. She does not move. Her silhouette, defined by the sharp angles of her wings and backlit by the city's glow, is the only form between the neon-lit void and the secret chamber now beginning to reveal itself.
