"Thank you for taking me in, Dean Sensei" Asuma says as he bows his head slightly.
He then proceeds to listen to what his Sensei expects him to do, while playing with a lighter in his right hand, opening and closing it.
"Well" Asuma continues, "Water is considered as one of the two (Doton) most versatile elements. The are practically infinite amount of uses one can have once he has mastered Water Element. It is capable of creating Water Bullets, Water Dragons, Dense spheres of water that are capable of trapping opponents, it is capable of flooding large portions of the battlefield, create mist that obstructs opponents vision, and rain that allows one to sense where the opponents are. Those are just some of the many uses of a water element."
Asuma says as he takes a quick breath. He than stares towards the small lake on his right for a moment, gathering his thoughts.
"Water techniques can be used with or without a source, with more powerful techniques requiring a water source. However, there are powerful Ninja who have high affinity for water, such as Tobirama and Kisame, who do not need a water source in order to preform even the most powerful of the water techniques. "
Asuma closes his lighter, and puts it in his left pocket, than proceeds to sit down.
"Water is strong against Fire because it is capable of extinguishing it, and it is weak to Earth, because Earth's solid structure is capable of stopping the flow of water. Another thing that should be noted is that water is a very good conductor of electricity, which in turn is why Storm element works the way it does."
"Also, water element is part of Kekkei Genkais: Ice Release, Wood Release, Storm Release, Boil Release and already mentioned Storm Release."
