Bat Controlling: Ultrasonic Mind Waves

Once the Sound Ninja Rinji controls his bats, he commands them to produce high frequency ultrasonic waves that affect the mind of the opponent.

These bats (along with Shino's evolving bug strategy) have been the only effective counters to the Crystal Style. The ultrasound waves move at a frequency that allowed the crystal to breakdown at a molecular level. Allowed dispersion of crystal particles back into the air.
