The Hyakki Gokuen is a hyper-stylized 3D anime-style weapon, resembling a traditional Japanese folding fan with exaggerated proportions and intricate detailing. The fan's ribs are made of a dark, polished metal, each ending in a sharp, blade-like point, while the fan's surface is crafted from a vibrant, translucent fabric that glows faintly with an otherworldly energy. The fabric is adorned with ornate, glowing kanji symbols that pulse with power, and the edges are lined with a delicate, yet dangerous, pattern of embossed demonic faces.
