A technique of pure destruction. Gaara creates a massive amount of sand in the forms of giant waves, covering and "drowning" the opponent in an ocean of sand. From the sand Gaara carries in his gourd, he grinds the rocks and minerals from underground into a large sea of sand and manipulates it like a tsunami that engulfs absolutely all the things in his line of sight. This raging sea deals a lot of damage by itself, but one can further take advantage of the sand for a second and a third consecutive assault. Gaara can control the sand, allowing him to attack his opponent while they attempt to outrun the wave. This technique has the added effect of changing the landscape. It is usually followed by an area crushing technique to kill the trapped opponent.
By the time of Part II, the sheer volume of sand Gaara uses to employ this technique increased dramatically, to sizes as large as Sunagakure and an entire desert; to the point that even Rasa thought he had undergone Tailed Beast Transformation when using the technique.
