Yamanouchi is a secret ninja school, located on top of a mountain in Japan. It was founded by Toshimiru, a master of Tai Sheng Pek Kwar, better known as Monkey Kung Fu, who carved the school out of the mountain using only a single weapon: a shape-shifting sword called the Lotus Blade. Since its creation in 338 AD, the school has guarded the blade, which can only fully be used in the hands of one who has been touched by Mystical Monkey Power.
