The Hyakki Gokufu is a legendary weapon in Street Fighter 6, embodying a hyper-stylized 3D anime aesthetic with its sleek, elongated blade that curves slightly towards the tip, resembling a traditional Japanese katana but with exaggerated proportions for dramatic effect. The blade features a high-detail, polished metallic surface with a vibrant, luminous blue hue that glows faintly, indicating its mystical properties, while the hilt is wrapped in dark, textured leather with intricate, ornamental engravings of mythical creatures. A distinctive design element is the swirling, ethereal energy that occasionally emanates from the blade, adding to its otherworldly presence.
