Purification Release: Purification Dome

With this technique the user can invoke a dome of energy that will protect it from any attack of the enemy. The dome of energy will remain raised until the user decides to undo it. While activated, the dome will prevent anyone who the user classifies as "unclean" to penetrate it, so it will repel any attack that the same may run against it and if there is direct contact with the dome and the enemy, it will have part of its chakra sucked into the dome. Those who the user classify as "pure" may cross the dome without suffering damages.
