Eight Gates Released Formation

The Eight Gates Released Formation (八門遁甲の陣, Hachimon Tonkō no Jin) is the act of awakening and releasing the internal restrictors that contain the body's chakra in eight limiter gates.

Overview
Any Shinobi who activates this state will temporarily gain powers greater than a Kage, but they will die because of the damage done to their body. Due to the immense amount of chakra flooding the body all at once, drastic changes can occur upon the user's body. The most common of these changes are the darkening of the skin, eruption of veins around the temples, the eyes turning completely white and green chakra flowing around their entire body, though this is not always the case. The user's voice also becomes deeper for the duration of the release.

Seireitou Hyūga's Version
Being a reigning Master in Taijutsu, Seireitou Hyūga had invented a variation of this technique that allows for him to use all eight of the inner gates without succumbing to death. Understanding that ki serves as the chakra that fuels jutsu and gives life to the body, neijing is the energy that provides shape and substance, such as the energy that allows the Shinobi's body and muscles to maintain themselves. However, neijing is often dormant and therefore remains useless in the hands of normal Shinobi, unless when used indirectly by martial art movements. In the hands of Seireitou, whom has gone through the necessary training to manipulate this otherwise inaccessible neijing force, he can use neijing as a carrier for the immense chakra released by the eight chakra limiters, allowing for safe passage through the body's muscles without causing damage that would normally result in death. Despite having such a method, Seireitou stresses the importance of allowing a "cool-down time" between the releasing of at least two gates before heading straight for the eighth gate.
