The Hyakki Gokai is a legendary weapon in Street Fighter 6, embodying a hyper-stylized 3D anime aesthetic with its exaggerated proportions and vibrant colors. It features a sleek, curved blade with intricate engravings of mythical creatures, glowing with a luminous blue energy that pulses as if alive. The hilt is wrapped in dark leather, contrasting with the polished, metallic finish of the blade, and includes ornamental details that hint at its ancient and mystical origins.
