Blocking Technique Absorption Seal

A highly advanced sealing technique granted by the Preta Path, that is capable of absorbing any chakra, regardless of any shape or nature transformation, and dispersing it within one's body by spinning the chakra within one's body in the opposite direction. As a result, this technique can absorb any ninjutsu based technique, regardless of power, without harming the user. Should the user get close enough to grab the opponent, the barrier can absorb chakra right out of an individual's body, effectively draining them.

During the Fourth Shinobi World War, Nagato used this technique to absorb Killer B's chakra while he was in his Version 2 form. He then apparently used the chakra to revitalise his body to its state before it was emaciated by the Demonic Statue of the Outer Path. It also restored his hair colour back to red.
