The Hyakki Gokuen is a hyper-stylized 3D anime-style weapon, resembling a traditional Japanese tessen (iron fan) with exaggerated proportions and intricate detailing. The fan's ribs are crafted from a sleek, metallic material with a glossy finish, alternating between silver and gold hues, while the panels are made of a translucent, iridescent fabric that shimmers with a subtle glow. The edges of the fan are adorned with sharp, angular patterns and embossed with mythical creature motifs, giving it a formidable and ornate appearance. When unfolded, the fan reveals a complex, symmetrical design with glowing kanji symbols that pulse with energy, hinting at its mystical properties.
