A futuristic elf stands against a neon-lit backdrop, her silver hair flowing like liquid mercury. Her left arm is a sleek chrome prosthetic, seamlessly integrated into her form, reflecting the vibrant city lights. In one hand, she wields a razor-sharp katana with a pulsating energy core, casting a soft glow on her sharp features. In the other, she grips a matte black pistol, its barrel etched with luminescent circuitry. Her piercing eyes are enhanced with digital displays, scanning the surroundings for threats. She exudes an aura of resilience and agility, a lone warrior navigating the gritty underbelly of the cyberpunk metropolis.
