New Fist of the North Star

New Fist of the North Star takes place in a post-apocalyptic world where almost all water is toxic, except for a reservoir that stores safe water. Sanga, the leader of the fortified zone called Lastland, sends a group of killers to obtain the safe water from a group of villagers who have discovered it. Unbeknownst to Sanga, Kenshiro, a skilled martial artist with expertise in Hokuto Shin Ken, intervenes to protect the villagers and thwart Sanga's plans.
