The Hyakki Gokai is a hyper-stylized, ornate weapon resembling a traditional Japanese war fan with exaggerated proportions and intricate detailing. The fan's ribs are crafted from a dark, polished metal with glowing, luminous blue kanji inscriptions that pulse with energy, while the fabric panels feature a vibrant, swirling pattern of red and gold, symbolizing flames and power. The edges are sharp and angular, designed for both aesthetic appeal and combat functionality, with a slight curvature to enhance its dynamic appearance in motion.
