This defensive technique creates a wall of water around the user. Enemy attacks are completely intercepted by a fence of water blown out from the mouth, and is raised from below with tremendous might. The water is blown out in the form of a circle around the user, and it makes for a defence without openings. It is also possible for the user to control the amount of water and duration at will. The wall's strength and resistance change following the quantity of chakra poured down into the water, so a skilful shinobi will be able to build a sturdy one. Furthermore, because the field of vision is maintained even while defending one can easily go on to the next move, which is a great advantage. The wall can also be formed from a pre-existing water source.
