Aquamaster

Water Magic (水の魔法 Mizu no Mahō) though mostly known for its user as Aquamaster (アクアマスター Akuamasutā) or Water Magician (水魔術師 Mizu Majutsu-shi), is an Elemental Magic that utilizes water.

Description
Aquamaster or Water Magic is a form of Elemental Magic revolving around the use of water, which is placed under the user's command for them to employ it for various purposes. Depending on its use, the physical properties of water can be manipulated to the user's advantage; large masses of such liquid are shown to possess remarkable force, being usable to inflict blunt damage upon targets by sweeping them away with water. A similar effect can be achieved using high-pressure currents, which, due to their reduced size, focus the damage on smaller areas. Pressure is also manipulable to a great extent, enough that when it is focused on the outer sides of the water surfaces being controlled, the liquid can become an effective cutting weapon, acting like a real blade. Whirlpools generated on the ground by this Magic, combining rotatory force and slicing power, can easily reduce solid rock to pieces.The user is also able to erect domes of water around foes, in order to knock them out by depriving them of air.

Magicians specializing in Water Magic can also achieve an extra, extremely versatile avenue of usage for such Magic: turning their own bodies into water at will. Such a peculiar employment allows them to become impervious to both physical and Magical attacks, which merely pass through them without harming them. In addition, the water from the user's body itself can be used as a medium to cast other spells related to this Magic (whereas casters unable to transform their bodies are apparently limited to using the water from the surrounding area), as well as have its properties altered, with the user being capable of making it boil without causing any damage to themselves. While unaffected by most types of offense, however, Magicians with a body solely composed of water are still susceptible to freezing, which can immobilize them and inflict damage upon them.
