Desert Wave

The user shapes their sand into a wall that can be used to protect them and allies, or to stand as a border to separate people. While initially appearing more curved, Gaara's usage eventually was shaped to appear more structured like a stonewall. Shinki's usage utilises Iron Sand, which is capable of withstanding Wind Release attacks with ease.

Trivia

 * Although Gaara first used this technique against Kimimaro, the technique was not revealed in the second databook (as many other techniques of that time were), but instead in the fourth (long after its introduction).
