Zero-Tails Sealing Technique

An unique form of sealing technique which passed down in Land of the Sky which used to seal (or restrain) Zero-Tails. This technique seems designed to utilise the dark chakra generated by Zero-Tails rather than seal it. This technique seems very complex sealing technique, caused by many preparations to do before, judged by many sealing formula or sigils scribed in the sealing room and a huge tablet used to restrain the beast.

Its unknown how this technique works, but after Zero-Tails sealed, it shown that the seal encased Zero-Tails like a cocoon and some body extensions grown and provide the Zero-Tails to generate dark chakra and transfer dark chakra created through the Ancor Vantian. This technique also protect Zero-Tails by absorbing any chakra from external sources which can harmed the Zero-Tails.

After Sasuke learned and known the mechanics of this technique, he broke the seal by destroyed the tablet that restrained the beast and Naruto dealing the death blow to it, the Zero-Tails went berserk and destroyed the entire sky fortress, killing all the Land of the Sky soldiers aboard.
