Well water release is one of the five chakra natures in naruto. Water release allows the user to create water from within or manipulate a water source.
Water release is strong against fire release, due to the water extinguishing the fire, but if someone uses a D rank water jutsu against a S rank fire jutsu, the fire will evaporate the water and win that elemental clash. So rank can effect the elemental battle. Water release is weak against earth jutsu's, due to the earth preventing the flow of water, rendering it useless. Many ninja's use water release e.g Kisame,Tobirama,and mei, but ninja's from kiri are known for their wonderful and power water jutsu's ^^.
Some water jutsu's are Water Clone Technique, Water Prison Technique,Water Release: Gunshot etc. I plan on using water jutsu's in a battle offensively, creating water projectiles, creating water whips etc. I plan on using it defensively, creating a wall of water, and I plan on using it as a distraction such as stormy blockade. I plan on combining water with other elements creating more powerful attacks, such as using water and lighting together.
