Thunder School

Thunder School (雷流, Rai-ryū; literally "Way of Thunder") is one of the eight schools of Physical Natures that make up all of Taijutsu. It focuses upon a ratio of Sei and Dō concepts, with Sei serving as the dominant source of energy while Dō is the supporting factor. Thunder is the nature of excitation, an explosive and quick-shot method of energy flow; utterly unrefined but destructive. While physical strength is important, the application of Thunder School techniques is strictly internal energy. A master of this school will find themselves capable of actually delivering fatal blows to their targets by simply being in contact with them physically.

The martial arts of Thunder School focuses on palm motions to deflect and fend off offensive assaults while striking with them in order to break through the opponent's defenses. It utilizes an internal explosive force that is meant to generate crashing concussive force from within the body without requiring actual physical motion in order to build it up. By learning this school of Taijutsu nature, one may actually deliver the strength of a normal punch straight into the opponent by a simple tap on their body.
