The Hyakki Gokurei is a mystical, ornate fan with a hyper-stylized anime aesthetic, featuring intricate engravings of spectral creatures and traditional Japanese motifs. The fan's ribs are made of a dark, polished wood, while the leaf is crafted from a semi-translucent, iridescent material that glows faintly with a supernatural aura. Its edges are sharpened to a fine point, suggesting it can be used as a weapon, with the overall design balancing elegance and menace.
