An obligatory question U_U
Senjutsu or Sage Arts, is a unique art which is granted to a ninja who has trained with either the toads or the snakes in the Sage Arts. The sage arts is the usage of natural energy which one will learn to draw upon its powers after extensive meditation and training. When someone draws upon the natural energy, they will become able to sense their surroundings with the natural energy flowing through them while their power rises to a whole other level. Their strength, stamina and speed is greatly increased as well as it opens up a new arsenal. Natural Energy however can be a dangerous tool, for the inexperienced, as it can turn someone to stone if you cannot balance it out with your own chakra.
