Yin Release: Raining Blades

This is a genjutsu that was created by Kashikoi during her training in genjutsu. How it works is that by using the Sukiru Secret Technique: Kaibyaku, she is able to open up her imagination to a point were blades start hitting the opponent. While these blades don't necessarily do any physical damage, they attack the brain and nervous system, making the opponent feel like there is actually damage being done.
