Transformation Technique

This jutsu allows the user to transform either themselves or another object into the appearance of another person, animal, or object. This is one of the basic jutsu taught at the Konohagakure Ninja Academy. Fundamentally, all ninja know this jutsu. The transformation technique is considered to be among the more difficult E-ranked techniques, since it requires constant emission of chakra while mentally maintaining the form. On top of that, the user would be, most likely, interacting with the environment. This puts much mental strain on the inexperienced ninja.

Tsunade of the Sannin possesses a more advanced version of the Transformation Technique, where she disguises her 50-years old self as younger versions of herself. Her technique is unique as it seems to be permanent, nor does she need to exert herself to maintain it for a long time, whereas a normal transformation would be dispelled when the user is injured. This form only breaks when Tsunade is low on chakra it also seems to be a fisical transformation.
