The Swift Release (迅遁, Jinton, Viz: Quick Style) is an advanced naturekekkei genkai that can be used to move with instantaneous speed, granting the user an advantage over opponents with more strength and speed, such as users of Chakra Enhanced Strength. This nature therefore renders the user invulnerable against most taijutsu. It is unknown what elements this nature entails.
How this nature differs from the common Body Flicker Technique, aside from speed difference, is unknown. It is possible that Swift-natured chakra is being applied to the Body Flicker, which is a general skill, to produce this effect.
