Modification Technique B Rank jutsu. Modification Technique is a much more advance form of Transformation Technique. This Technique can be permanent. This jutsu can change parts of the users body exactly like the Akimichi clan's Partial Multi-Size Technique to increase there strength. Anyone using this jutsu can also decrease his muscle mass to greatly increase there speed. By decreasing the users Muscle mass the users size appears to be that of a three foot child but with the speed of opening the Second Inner Gate.
