Lake School

Lake School (沼流, Numa-ryū; literally "Way of Lake") 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 Dō serving as the dominant source of energy while Sei is the supporting factor. Lake is the nature of joyous stagnation. It is a defensive school; the opposing discipline to that of the Mountain School.

Whereas the Mountain nature is about stillness of the artist themselves, the Lake School is about the stillness of one's opponent. Just like a Swamp, which ensnares one in its thick muddy waters, the practitioner focuses on arm-locks and restrictive direct attacks which are supported by swift indirect methods, with the intention of rendering the target unable to advance. The Lake School is Dō-prominent, therefore meaning that it favors the Heaven School over the Earth School; subsequently meaning that it focuses upon expansive force rather than receptive force to overwhelm the opponent.
