Eradication of the Root of Evil is truly Sunate's most interesting technique. Unlike it's parent technique it not only allows the user to manipulate water and moisture around him but to further change their state, shape and much more. To use this, thunder clouds and storm like conditions are required since this technique utilizes the power of rain. If there are no active thunder clouds, the user must create them by using powerful fire techniques to produce the necessary storm conditions. This technique, allows him to control the weather in the immediate vicinity, or more specifically, the water in the surrounding atmosphere. Like it's other parent technique the rain eats up any chakra when it comes in contact with that is not of the same signature as the original user. By further employing shape manipulation these drops of rain can be converted into spears of water, which are capable of cutting the targets cloth and piercing his skin. By adding his wind-natured-chakra to this rain, he can essentially generate a blizzard with multiple ice shards. Later on, the user would cause five big tomoe's of ice to appear around his target(S), once marked a barrier of ice will be formed which cannot be melted or damaged from inside (this self claimed fact by Sunate was proved wrong when a Shinobi used some strong fire based ninjutsu to melt the barrier). If anyone tries to touch the barrier, his body begins to freeze. Inside the barrier, the opponent is exposed to a violent storm. Once trapped, these each tomoe sends a line of ice shards towards them. Hitting them continually. This can be proved to be very fatal if not deadly. To make sure the opponent does not escape the ice shards, two hands of ice can be formed inside the barrier which would hold the legs of the target(S) rendering them immobile.
The fact that this technique is referred to as "Ice Release" is not due to the fact that it is a kekkei genkai, but presumably because the basic elements water and wind make up the actual advanced nature transformation of Ice Release.
