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 fan's surface features vibrant, painted depictions of mythical creatures and swirling patterns. Distinctive design elements include glowing edges that pulse with energy during combat, and ornate engravings along the handle that hint at its mystical origins.
