The user can perform a burst of speed that allows the user to move so fast it appears as if they have teleported (in some cases, the user actually does teleport short distances), many users can sustain only short dashes. In most cases the user is able to maneuver at the high speeds accurately and does not cause any shock or disturbance to the surface they step on.
This technique is commonly used to dodge projectiles, move behind enemies, show off-speed, get away from a fight, etc.
Afterimage Creation: The user moves fast enough to leave an afterimage of themselves making it appear as if there are multiple of him or herself. The copies may appear stationary or be capable of taking action.
Air Dashing: The user moves with enough momentum and leg strength to dash through midair.
Double Jump: Applying enough leg strength to jump off ground level and flash-stepping in the air.
The quick movements and the quick stops may put a strain on the body, breaking bones, destroying internal organs, or the air pushing against one's chest could cause respiratory arrest. The speed moving could theoretically flay both skin and muscle from the bone.
