Super Fist of The North Star

The story centers on a warrior named Kenshiro, the successor of a deadly martial art known as Hokuto Shinken, which gives him the ability to kill most adversaries from within through the use of the human body's secret vital points, often resulting in an exceptionally violent and gory death. Kenshiro dedicates his life to fighting against the various gangs, bandits, and warlords who threaten the lives of the weak and innocent, as well as rival martial artists, including his own "brothers" from the same school.
