The Hyakki Gokuen is a hyper-stylized 3D anime-style weapon, resembling a traditional Japanese folding fan with exaggerated proportions and intricate details. The fan's ribs are made of a sleek, dark metal with a glossy finish, while the panels are crafted from a translucent, iridescent material that shimmers with a subtle glow, suggesting magical properties. The edges of the fan are sharp and angular, designed for combat, with engraved patterns depicting mythical creatures and symbols that enhance its mystical aura.
