The Hyakki Gokusho is a hyper-stylized 3D anime weapon featuring a sleek, curved blade with intricate engravings depicting mythical creatures and floral patterns. The blade has a polished metallic finish with a vibrant blue hue that glows faintly, suggesting magical properties. The handle is wrapped in dark leather with golden accents, providing a stark contrast to the luminous blade, and ends with a ornate pommel shaped like a demon's head.
