A medium shot from a low-angle view featuring a katana-shaped lightsaber floating vertically in the center of the frame. The weapon consists of a traditional Japanese tsuba (guard) and an ornate hilt wrapped in black rayskin and silk ito, from which emerges a brilliant, humming blade of concentrated plasma light in a vibrant cyan hue, mimicking the curved edge of a katana. The blade casts a strong glow and emits small electrical sparks and luminous particles into the surrounding air. The background is a dark, minimalist void of deep charcoal grey, creating a high-contrast environment that emphasizes the light emission. The visual style is a high-quality anime illustration with sharp linework, cinematic lighting, and a strong depth of field effect that keeps the hilt in crisp focus while the tip of the plasma blade slightly blurs. The overall atmosphere is futuristic yet traditional, conveying a sense of power and serenity.
