The Hyakki Gokuen is a hyper-stylized 3D anime 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, pointed tip, while the fabric between them is a vibrant, luminous silk that glows faintly with an otherworldly energy. The surface is decorated with ornate, embossed patterns depicting mythical creatures and kanji symbols, giving it a mystical and battle-ready appearance.
