Barrier Sealing Formation

Four users must stand in a square formation. The distance they are away from each other will determine the size of the barrier. They then do the hand seals required for the technique which will form a giant cube which surrounds the area between them which the enemy will be in from every direction including underground. This barrier is almost impossible to break as it can withstand a tailed beast ball. This technique can even be used to keep tailed beasts at bay. The size of the barrier can be increased or decreased by the four users performing specific hand seals with perfect synchronization. Special sealing tags can be placed on each corner of the barrier so it can be maintained for a period of time without the users. This technique can be performed by one user with the help of shadow clones.
