The Hyakki Goketsu is a hyper-stylized 3D anime weapon, resembling a traditional Japanese katana with exaggerated proportions and vibrant energy effects. The blade is long and slightly curved, with a glowing cyan edge that pulses with power, while the hilt is wrapped in dark red fabric with golden accents. The guard is ornate, featuring intricate demonic motifs and small, floating talismans that emit a faint glow. The overall design combines sleek, angular shapes with organic, flowing energy trails.
