The Hyakki Shu is a hyper-stylized 3D anime weapon, resembling a traditional Japanese fan with exaggerated proportions and intricate detailing. The fan's ribs are crafted from a sleek, metallic material with a glossy finish, while the panels are made of a translucent, iridescent fabric that shimmers with vibrant colors. The edges are adorned with sharp, angular patterns and glowing runes, suggesting a mystical or magical effect.
