By drawing out a large amount of black sand from the surrounding area Takashi is able to create a massive amount of black sand that travels towards an opponent at fast speeds in the form of a wave, covering and "drowning" them in an ocean of sand. The large wave of black sand will rise up to about several feet above the opponent. Takashi is able to control the flowing black sand wave, allowing him to attack his opponent while they attempt to outrun the wave. The technique is powerful enough to devastate an entire landscape, as Takashi is able to destroy acres of forest land turning it into nothing but a wasteland with occasional dead trees. This technique requires a large amount of chakra to perform but can also be used to take out a large number of opponents due to the fact that it is almost virtually unavoidable.
