Water Release: Water–Heavens Convergence

This technique enables the user to control water and moisture around oneself much like Gaara controls his sand. It can be used to block most incoming attacks, bind or drown opponents, and shape the water into various attacks, allowing the user in conjunction with the Summoning Technique to allow water-based summonings to fight in areas that it normally need water to move around by either trapping the target in the same water or manoeuvring the water to allow the summon to chase the target. It is able to extract and utilise groundwater, and as is very effective most areas, but useless in rocky areas.

Trivia
