Heaven School

Heaven School (天流, Ten-ryū; literally "Way of Heaven") is one of the eight schools of Physical Natures that make up all of Taijutsu. It focuses solely upon the principle of Dō, making it a style of absolutely aggressive nature that uses overwhelming force and strength to dominate the opponent(s). Just as the skies themselves are expansive and infinite, this is a school of martial arts that teaches to grow and expand further in order to continuously gain greater power. Seireitou has referred to this as the pinnacle of the Strong Fist.

The martial arts of Heaven School focus more on hand strikes, mostly clenched fist punches that strike with blunt force. Constant conditioning of the body is mandatory as physical strength becomes key in overcoming adversity with this school of martial arts combat. Those who train in the Heaven School often condition their hands and their body to become as hard as iron itself.
