Ryūsui

Ryūsui was created by the Fifth Mizukage, Ranketsu Yuri which allows the user to become water in a matter akin to the Hydrification Technique.

Usage
Activating Ryūsui causes the user to rapidly absorb all nearby humidity, water, and otherwise liquids and rapidly break them down in the body. This broken down water then merges and alters the body's molecular state, essentially turning the individual into a pseudo-Hōzuki.

Overview
This technique makes it impossible to receive damage from physical attacks. From a single hair, to the skin and muscles, everything can be liquefied and solidified at will. Applying this technique, the user can also modify their body parts for suitable situations or even use the liquid as projectiles.

In order to speed up the rate of absorption, the user can employ the Water Release: Water Sky Convergence technique. By doing so, the user is able to double the rate of absorption and thus achieve full immersion in one post, interrupted or not.

Disadvantages
This technique requires two uninterrupted posts of absorption in order to achieve full immersion. It also makes the user more susceptible to Lightning Release techniques. The user cannot employ any other nature transformation except for Water Release.
