Nintaijutsu in action in the form of A's Lightning Release Armour.
Nintaijutsu (忍体術, literally meaning: Ninja Body Techniques)[1] is a term used to describe the fighting style used by the Third,[2] and Fourth Raikage. A combination of ninjutsu and taijutsu, the Raikage uses nintaijutsu by first surrounding himself with his Lightning Release Armour. This augments the strength of his physical attacks, making them even deadlier. His speed and reflexes are also increased. It is unknown if there are other examples of nintaijutsu.
