Masako, upon forming the required hand seals, breathes out a single plume of water vapour with a low acidity, as opposed to the higher acidity seen in most techniques. This is done so because of the shape transformation required in this technique to stabilize the technique as it makes contact with another surface, dispersing it into a number of projectile-like arrangements. Upon doing so, Masako controls the acidity of the mist to become much stronger before directing it as a projectile to cause the corrosion of a variety of substances with meticulous ease. The level of power this technique holds is enough to rather easily corrode through strong chakra-based defenses and the like without interruption of the general flow of the technique. It also appears that, though the technique is rather strong, if not carefully utilized it can cause excessive damage before eventually dissipating.
