The "Tight-Fillet" in "Black Myth: Wukong," is a magical headband placed on Sun Wukong by the monk Tang Sanzang. This circlet is enchanted, tightening painfully whenever a specific chant is recited, forcing Wukong to obey his master's commands. The circlet symbolizes control and restraint, serving as a reminder of Wukong's journey from a rebellious spirit to a disciplined disciple. It is often depicted as a simple, yet powerful, gold band that rests on his forehead.
