Rihaku, leader of the Nanto Five Chariot Stars, orders Hyui and his motorcycle-riding Wind Brigade to begin attacking Ken-Oh's outposts. Meanwhile, Kenshiro encounters one of Ken-Oh's enlistment groups and infiltrates them. He finds the group run by the ruthless but cowardly David, who uses Glenn the Killer Machine, a man he raised only to fight. After Ken defeats Glenn, he renounces his evil ways, only to be betrayed by his master David, who orders his men to kill Glen. As David and his men flee from Ken, they are slaughtered by Hyui and his Wind Brigade.
