Crystal Release

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

Using Crystal Ninjutsu, the user can crystallize any physical material (including targets) around them, turning them into a weapon or in the latter case, solidifying targets down to the 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. Crystal Release users can also manipulate already-existing Crystals and crystalline structures.

Crystal Ninjutsu is strong against Earth and Water Ninjutsu as earth and water are physical masses that can be crystallized and then turned against the Crystal user's opponent. The only apparent weakness of the Crystal Release is that it cannot crystallize either raw energy or chakra as they have no physical mass to crystallize, allowing a person with either energy-based jutsu (such as Fire and Lightning Ninjutsu) or good chakra control to properly counter it. Jutsu which uses either energy or chakra have proven to be effective in combat against Crystal Ninjutsu. Wind Ninjutsu are in equal stance with Crystal Ninjutsu, as Naruto and Gamatatsu were able to pierce the huge crystal labyrinth using Wind Release: Toad Gun, yet Guren was able crystalize the same technique and manipulate it into a dragon.
