Alright then.Water is the molecule created by 2 hydrogen single bonded to a owygen. Theses molecules are held together by the intermolecular force refered to as the hydrogen bond. Water is also the key to life - the human body is mostly made of water. Plus, the Earth is covered mostly by water.
Water can be used to exterrminate fires by cutting off the flow of oxygen and absorbing the heat. However, if the fire is really hot, the water can be evaporated. In rare cases, when in extreme temperatures, fire can actually cause the water to be denatured, meaning that the water breaks down into oxygen and hydrogen which actually acts as fuel to the fire (This is what happened at the nuclear reactors in Japan last year after the earthquake)
A shinobi can mold his chakra and channelel it through water in order to manipulate the water. This is refered to as water release or suiton. Some examples of water release jutsu are Water Style: Water Dragon, Water style: Water Wall, Water Style: shark bomb, Water Release Water bullet etc.
Some famous shinobi who have used the water release are the sevenswordsman of the hidden mist (shinobis from Kiri often have a water affinity - Mei Temuri, Hōzuki clan), Kakashi Hatake, the First Hokage (Part of Wood Release kekei genkei), the Second Hokage (rumored to be the greatest water release user ever), Itachi Uchiha, Danzo, Gamabunta, etc.
Water Release Jutsu are strong against fire release but weak to Earth Release.
Water release can be combined with earth release for the kekei Genkei wood release, wind release for Ice Release, lightning release for storm release, and fire release for boil release. In addition, a long range suiton jutsu can be used to lengthen the range of certain raiton jutsus. Suiton can also be used to augment the power of certain fuiton jutsu.
There is a clear disadvantage of the last jutsu, and that is that it needs a water source, otherwise you won't be able to use it(Suiton: Mizu Kuri No Yaiba) - Water Style: Sword of Draining
Rank: D
Range: Short
Chakra cost: 10
Damage Points: 20
Description: A technique that utilizes water to create a sword. The sword can be wielded in the normal fashion, allowing the ninja to cut and stab like with a normal blade.
Note: Doesn't require a water source.
How you perform it: *I channel suiton chakra into my right hand. A sword of water forms in my right hand from the water formed by the chakra*.
Advantages: It does not require a water source and it can serve as a weapon if the user is disarmed.
Disadvantages: It has a short range and is a low rank.
How would you defend yourself from this jutsu: I would probably use a high rank fire jutsu to evaporate the sword or fight from mid range or long range.
