Twin Arm - Big Crunch: Zero-order Convergence (双腕・零次集束, Futaude - Reiji Shūsoku?), also called Right Hand - Big Crunch: Right Arm - Zero-order Convergence (右腕・零次収束, Migiude - Reiji Shūsoku?), is a technique utilized by Amakusa Shirou Tokisada with his two arm Noble Phantasms, Left Hand - Xanadu Matrix and Right Hand - Evil Eater, connecting with the Greater Grail.
By connecting both arms to the leylines, excessive Magical Energy is inserted in the Magic Circuits of both arms and made to rampage. A destruction-type Noble Phantasm that refines pseudo-black matter and swallows all beings on the surroundings. Because it requires an excessively vast magical energy, originally it is impossible to employ it as a Noble Phantasm. In order to completely impel it as Noble Phantasm, he must first somehow establish a magic energy supply route different from his Master.
