Niz using Mass Driver against Sechs in Phase 30.
Mass Driver (マスドライバー Masudoraibā?) is an offensive technique used by Niz that is derived from the railman's role of launching cargo into space using a rail suit. Gripping a target with one of the suit's hands, Niz powers up his rail suit to launch the target at a speed high enough to reach escape velocity and break free of a gravity. Mass Driver is much more powerful than a conventional cargo launch as the target breaks the sound barrier.
