Water Breathing derives from Sun Breathing.
It mimics water, specifically the flow, flexibility and adaptability of the liquid and replicates it with the user's movements, techniques and abilities. Most, if not all, known techniques involve the user bending their body, arm and weapon in a fluid motion to match the movements of rushing or flowing water. Users also visualize themselves seemingly creating and manipulating water when unleashing its techniques.
