The Hyakki Gokusho is a hyper-stylized 3D anime weapon, resembling a traditional Japanese oni mask fused with a mechanical gauntlet. It features a predominantly dark red and black color scheme with glowing blue accents that pulse with energy. The mask portion is intricately detailed with sharp, angular designs and menacing teeth, while the gauntlet is sleek and armored, with visible pistons and gears that suggest immense power. The surface is a mix of polished metal and rough, textured areas that give it a battle-worn yet formidable appearance.
