Demonic Illusion: One Thousand Chirping Birds

This technique is one that relies on whistling to be activated. Upon being caught in the genjutsu the victim will start hearing a large amount of sparrows chirping, which increases soon increases in volume to deafening levels, causing intense pain throughout their body and bringing the victim to their knees in the real world from the pain they think they are experiencing.

While a useful technique requiring no hand seals, its effects can be avoided if they block their ears, nor does it work on the deaf.
