This is the version where nobody's holding the camera back. Four episodes of Souten no Ken that never made it to broadcast, 16, 17, 18 and 21, dumped straight to disc with every frame intact, which means Hokuto Shinken finally gets to finish what it starts on screen instead of cutting to a shadow. Kasumi Kenshiro's pressure point work is the whole point of the style, and watching a body come apart from the inside in full detail is the difference between hearing about the 62nd successor and understanding why Shanghai called him Yan Wang. The 1930s underworld setting was always too grimy for TV standards anyway, all smoke and blood and men who deserve it. If you only saw the aired run, you saw the polite edit. Put these on and find out what the censors were protecting you from.
Fist of the Blue Sky OVA is a four-episode action release from 2007. It gathers episodes 16, 17, 18 and 21 of the Souten no Ken television anime, which never went to air and were instead put out on DVD. Since they skipped broadcast, these episodes come in uncut and uncensored form.
