The Hyakki Gokuen is a hyper-stylized 3D anime 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 panels are made of a translucent, iridescent material that shimmers with every movement. The edges are sharp and angular, designed for both aesthetic appeal and combat efficiency, featuring ornate carvings of mythical creatures that seem to come alive when the fan is in motion.
