The Dehydration Technique is a Hiden technique found within the Hayashi Clan. This technique allows the user to control the water supply within their oppenent's body. This was originally used to stall or stop the opponents altogether, but through the help of Yukimaru Hayashi, a notable clan member, it was learned that the water could be taken from the enemies' bodies as well. Years later, another discovery was made about the technique; the members were now able to freeze the water supply, inside or outside the body. This technique requires both water and wind release; water to control the water supply, and wind to suck it out of the body.
