A very advanced technique, those without the mind of Gaoh would find it hard pressed to replicate. This jutsu though not actual time regression might be the closest possible thing. Gaoh spreads his unique chakra over 60ft radius thus fills everything within that space with his chakra. At this point the jutsu retains a memory of the area to a perfect likeness. When the area is damaged by natural effects or by powerful techniques, this jutsu causes every last atom with chakra from the earlier mention area to return. These atoms align themselves perfectly to how they were before. And even after the area is completely decimated or unrecognizable, the areas can be restored to its former state. This jutsu is the absolute best form of recovery because the second state can be started instantly. Thus even after the area has been destroyed, everything that was in it when the jutsu made memory is returned back to how it was.The only thing this jutsu doesn't effect during the regression is the users memory of what happened. Gaoh only uses the Tiger handseal for this technique. This jutsu takes a minimum 10 minutes to meditate to use. First to release the chakra and make a memory then again to regress the chakra. In the case of human being this isn't resurrection. Due to the fact that the second effect must be activated before-hand, this would be taking and simultaniously repairing potentially lethal damage. This repair isn't done in the form of a typical medical jutsu either. Rather more like putting together a house thus it isn't a medical jutsu either.This jutsu doesn't require maintenance between the time when the memory is finished and made to the time when the area is turned back. This is due to the fact that the second application of chakra activate the memory but the memory made is permanent for one use.

Drawbacks:

• Causes extreme exhaustion to the use.
• Stinging sensation in the users joints.
• Loses the abilty to use your left arm for 6 hours.
• Hard to perform mid battle.
