The Hyakki Gokai is a hyper-stylized 3D anime weapon, resembling a massive, ornate kanabo (spiked club) with exaggerated proportions. Its surface is heavily textured with intricate engravings of demonic faces and mythical creatures, blending traditional Japanese motifs with fantastical elements. The club's spikes are sharply angular, glowing with a faint, eerie luminescence, suggesting supernatural power, while the main body is crafted from a dark, metallic material with a slightly weathered finish to imply age and battle use.
