The Hyakki Gokuen is a hyper-stylized 3D anime-style weapon, resembling a traditional Japanese fan with exaggerated proportions and intricate detailing. The fan's ribs are made of a polished, dark metallic material, while the fan's surface features vibrant, luminous patterns that glow faintly, suggesting magical properties. The edges are sharp and angular, designed for both aesthetic appeal and combat effectiveness, with engraved symbols that hint at its mystical origins.
