The Hyakki Gokuen is a hyper-stylized 3D anime-style weapon, resembling a traditional Japanese war fan with exaggerated proportions and intricate detailing. The fan's ribs are made of a sleek, metallic material with a glossy finish, while the panels are crafted from a translucent, iridescent fabric that shimmers with vibrant colors. The edges of the fan are adorned with sharp, angular designs and glowing runes, giving it a mystical and formidable appearance suitable for high-energy combat.
