Hokuto Shinken
"Hokuto Shin Ken" (North Dipper God Fist) is an ancient Chinese martial art, dating back 2000 years to the island of Asura. Its founder was Shuken of the ancient "Hokuto Sōke" ruling line. This martial art makes use of the opponents' 708 Keiraku Hikō, also known as tsubo or pressure points. These pressure points destroy the enemy from within. The Hikō can also be used to heal. While a normal fighter uses 30% of his natural abilities, a Hokuto Shin Ken successor knows how to ultilize his remaining 70%. Hokuto Shin Ken can only be passed down from one father to one son, and there can only be one successor at a time. Sons that do not succeed in becoming successor must never practice the art again, or risk having their memories erased and fists shattered. The ultimate Hokuto Shin Ken attack is the Musotensei, which can only be performed by one who completely understands sadness.
"Hokuto Shin Ken" is named after the "Hokuto Shichi Sei" <North Dipper Seven Stars>, which is the same thing as the "Big Dipper".
