Ultrasonic Waves of Increasing Oppression

This technique allows Yasuga to emit extremely loud, high-pitched sound waves from his mouth which can disorient, render unconscious, and even kill his opponent. The frequency and amplitude of Yasuga's chakra is greatly increased, and then he releases it as a powerful sound wave. This sound wave damages the ear drums of those who hear it. Yasuga, however, is immune to its effects. When used in conjunction with Yasuga's special kunai, the power of this technique increases greatly, due to the vibrations of the metal.
