Secret Technique: Mouth Seal Technique

The user initiates the technique with a specific technique seal and apparently before asking the target a question. If the target answers, the technique is then immediately invoked causing the person to lose the use of their voice. The target will remain in this state until the technique is dispelled by the user.
