Executed by performing a quarter-circle forward motion and pressing kick, Juni will perform a teleport. Distance is determined by the kick button. The light version goes little ahead of Juni. The medium version through 25% of the screen. The heavy version through half of the screen.
The light version is good for faking out opponents, though the heavy version is the safest version of all.
Mach Slide can be used to escape from enemy attacks or to approriately position Juni around her opponent (also as a cross-up).
