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. The edges of the fan are adorned with sharp, angular designs that glow faintly, suggesting a mystical or supernatural power. The overall design is asymmetrical, with one side featuring ornate engravings of mythical creatures and the other side left smooth for contrast.
