A futuristic street samurai stands poised on a slick, reflective rooftop, bathed in the glow of neon city lights sprawling beneath them. Clad in sleek armor that shimmers with electric energy, they grip a pulsating energy katana, its blade radiating a vibrant blue hue. The skyline is alive with towering skyscrapers, holographic advertisements, and the hum of drones, creating an atmosphere of high-tech tension and urban mystique.
