Sound Shuriken

After putting a dozen or more shuriken on display by suspending them in the air with chakra threads, Yoin forms the necessary seals to build up chakra and converts it, before expelling it in the form of a blast wave of sound, that not only destroy physical structures in front of him but also propel all the shurikens at once at supersonic speeds, causing them to break the sound barrier and create a sonic boom behind them. According to Yoin, he is able to launch these shurikens as fast as 850 miles per hour, which grant them the ability to cut steel and other solid objects due to their momentum.
