The Hyakki Gokuen is a hyper-stylized 3D anime-style weapon, resembling a traditional Japanese folding fan with exaggerated proportions and intricate designs. The fan's ribs are made of a sleek, metallic material with a glossy finish, while the panels are crafted from a durable, textured fabric that features vibrant, luminous patterns depicting mythical creatures and swirling energy. The edges of the fan are sharpened, suggesting its use as a melee weapon, with a subtle glow emanating from the engravings that hint at its magical properties.
