The Hyakki Gokou is a hyper-stylized, ornate armor set inspired by Japanese mythology, featuring a blend of organic and geometric shapes with intricate engravings of mythical creatures. The armor is predominantly metallic with a glossy, reflective finish, accented by vibrant, luminous colors that glow subtly, enhancing its mystical aura. Distinctive design elements include asymmetrical shoulder guards resembling demonic faces and a flowing, fabric-like lower section that moves dynamically during combat.
