The Hyakki Gokuen is a hyper-stylized 3D anime weapon resembling a traditional Japanese folding 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 when in motion. The edges of the fan are adorned with sharp, angular designs that glow faintly, suggesting a mystical or supernatural power, and the handle features ornate carvings of mythical creatures, adding to its legendary status.
