The Hyakki Gokoku is a hyper-stylized, ornate shield with a circular base, featuring intricate engravings of mythical creatures and symbols that glow with a vibrant, luminous energy. Its surface is a mix of polished metal and translucent crystal segments, creating a reflective and iridescent finish that shifts colors under light. The shield's edges are sharp and angular, with a slightly asymmetrical design that emphasizes its mystical and otherworldly origin.
