After performing a long string of handseals this technique traps the target in a large box of black mist with a purple outline around it. The first stage of the attack slowly destroys all the senses except touch, afterwards the large "coffin" of mist begins to suffocate the flow of chakra. causing it to stop moving. Th final stage of the technique results in the black mist crushing the targets body, but imploding the box. This technique seems to be Zukia's trump card move, as well as taxing him a great amount of his enormous chakra.
