The Hyakki Gokufu is a hyper-stylized, ornate weapon resembling a traditional Japanese fan with exaggerated proportions and intricate detailing. Its frame is crafted from a dark, polished metal with glowing, luminous accents that pulse with energy, while the fan's surface features a vibrant, painted design of spectral imagery and mythical creatures. The edges are sharp and angular, suggesting its use as a melee weapon, with a complex, asymmetrical shape that enhances its dynamic appearance in combat.
