The Worldline Zero is a sleek, futuristic sword with a blade that appears to be made of a shimmering, energy-infused material, giving it a luminous, almost ethereal quality. The hilt is designed with a high-tech aesthetic, featuring angular, geometric shapes and glowing blue accents that pulse with energy. The blade itself is slightly curved, with a sharp, pointed tip and a smooth, polished surface that reflects light dynamically, creating a sense of motion even when stationary.
