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 feature a vibrant, luminous pattern that glows faintly, suggesting magical properties. The edges are sharpened to imply combat functionality, with subtle battle-damage textures that add to its storied appearance.
