Turn back time to the beginning of the battle.Final Fantasy V description
Return (リターン, Ritān?), also known Reset, is a recurring ability in the series.
Using the Return/Reset spell during battle will cause the battle to reset. It is useful during battles when a strategy goes awry, or when the player is trying to steal a rare item. Some enemies are also known to use Return/Reset, such as Omniscient. There are also a number of enemies that have Return/Reset available as part of the set of spells that can be accessed when they are controlled by a Beastmaster, even though they don't use it normally. Additionally, casting Return/Reset in a battle begun with a back attack will generally reset it to a condition more favorable to the player.
In battles with a timer, the Return spell is supposed to reset the battle and, also restart the timer. This is bugged in the North American GBA version, but is fixed in the European version.
Return is a powerful magic used by Chronos and Kairos in the ending of the game's second chapter, in an attempt to repair the crystal.
