Dry Release

is an advanced nature kekkei tōta, an advanced version of kekkei genkai, which is created by combining the earth, wind, and yin natures.

Dryness is the lack of water, which can happen for any number of reasons, for example, evaporation and chemical dehydration. In arid places, the ground can show dessication cracks and the air have very low humidity, making it unhealthy to breathe in. Yin's form creation aspects could play on those characteristics of earth and wind, dehydrating what it hits. The Yin principle doesn't correspond to actual dryness in real life, that would be Yang, but since it is associated with dampness, it can also work by removing water from things to make itself damp.

Most of the techniques of this nature are reminiscent of those that use sand with their ninjutsu; however, this element mainly deals with draining the moisture in both the living and non-living. This ability stems from the more destructive eroding power of the ancient ghost named Serean, though it is considered weaker yet still just as dangerous especially when the user makes physical contact.

Trivia

 * Credit for the concept (found here) goes to Omnibender and ShounenSuki (for creating the icon .svg).
 * So far, the only way to attain this ability is to have oneself be "partially corrupted" by Serean's taint, which is risky and dangerous in itself.
