A moody, high-contrast scene: a 16-year-old girl with vibrant multicolor hair featuring pink and green streaks, styled in twin tails with ahoge framing her face. She wears a dark-hued halter dress with detached sleeves, showcasing bare shoulders and sagging breasts. Her bright green eyes sparkle under sharp, natural lighting. Mechanical ears and round glasses add a touch of tech-savviness. Soft makeup accents her features, including subtle eyeliner, eye shadow, and glowing lips. In the background, muted tones evoke a sense of mystery, as if the scene is bathed in a soothing twilight glow.
