Crystal Release

The are techniques that manipulate crystal. It's seen only in the anime, and its only known user is a woman called Guren. This element appears to regularly use a Ram hand seal.

Using Crystal Release, the user can induce a process which will crystallize anything around them--like bodies of water, moisture in the air, even bodily fluids--turning them into a weapon or solidify targets down to a cellular level, imprisoning and even killing a victim should the crystal ever be struck, reducing the mass of crystal and the victim down to crystalline dust. It has yet to be demonstrated if the process that crystallized victims can be reversed. Users of Crystal Release can also manipulate already-existing Crystals and crystalline structures. Crystal used in Crystal Release are either Blue (i.e. Crystal Release: Jade Crystal Blade,) Green (i.e. Crystal Release: Jade Crystal Mirror for her Jade Crystal Clone Technique,) or most commonly pink (as seen by the bulk of Guren's techniques.)

When a Konoha recon team, consisting of Kakashi, Shino, Kiba, Akamaru, and Hinata, first encountered the victims of Crystal Release, they pondered that such a type of jutsu, characterized by its ability to crystallize its targets, might possibly be an earth-natured ability. The only apparent weakness of the Crystal Release is that it cannot crystallize raw chakra, allowing a person with enough chakra control to resist being inwardly crystallized. Furthermore, techniques of a Lightning, (because of the possible earth-nature,) and Fire type also appear to be rather effective in combat against the Crystal Release.
