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 sleek, dark metal with a polished finish, while the panels are crafted from a vibrant, translucent material that glows faintly with an otherworldly energy. The edges are sharp and angular, suggesting its use as a melee weapon, and the surface is adorned with ornate, glowing kanji symbols that pulse with power during attacks.
