A very complex jutsu, but also extremely powerful if it goes through until the very end, making the most damage out of all Water jutsus. Even though it consists out of several components, the whole performance can be done very quickly. Since you have to be a Water primary specialist, that already means that you can perform it with only one hand seal, makig it even faster. No water source is requires, and you get a pool for your future Water jutsus! Once the first part of the jutsu goes through, and it's very probable since the stream of water is explosive and instant (especially if the opponent is in mid range), and they get thrown into the air, it's hard to defend against the next phases of the attack. If one were to choose mastery of Water, this would definitely be one of the strongest jutus they would have in their basic 5 arsenal.
