Four Red Yang Formation

A powerful barrier formation noted to only be usable by those of Kage calibre, whereby four shinobi, standing in a square formation, erect a large barrier that is red in colour. It was stated to be several times stronger than the Four Violet Flames Battle Encampment, and is highly malleable. When assaulted by a Tailed Beast Ball from the Ten-Tails, the barrier simply distorted its shape, forcing the brunt of the attack upwards while it was left completely intact. Its users can create openings within the barrier to allow passage.

The barrier is apparently very chakra-taxing since at least two of its users are limited in the useage of other techniques, such as clone techniques, while maintaining the barrier at the same time.
