“Create a futuristic Japanese katana sword made of matte graphite with a sleek, sharp blade. The edge and details are highlighted by glowing blue neon lights in a sci-fi style. The handle features a modern, ergonomic design with subtle blue neon accents as well. The sword’s surface combines traditional Japanese aesthetics with high-tech elements like smooth metallic and carbon fiber textures. The overall look should be dynamic, powerful, and technologically advanced.”
