The Hyakki Gokuen is a hyper-stylized 3D anime-style weapon, resembling a traditional Japanese tessen (iron fan) with exaggerated proportions and intricate detailing. The fan's ribs are crafted from a dark, polished metal with glowing cyan engravings that pulse with energy, while the segments between are made of a translucent, iridescent material that shimmers with every movement. The edges are sharp and angular, designed to look both elegant and deadly, with a slight curve to enhance its dynamic appearance in combat.
