The Hyakki Gokusho is a hyper-stylized 3D anime weapon featuring a sleek, curved blade with intricate engravings that glow with a vibrant, otherworldly energy. The handle is wrapped in dark, patterned fabric, contrasting with the luminous blade, and the guard is designed with ornate, asymmetrical motifs that resemble demonic faces. The overall design balances sharp, angular lines with fluid, organic curves, embodying a fusion of traditional and fantastical elements.
