Takamine Kiyomaro, a depressed don't-care-about-the-world guy, was suddenly given a little demon named Gash Bell to take care of. Little does he know that Gash is embroiled into an intense fight to see who is the ruler of the demon world. All of the demons have to pick a master on Earth and duke it out with other demons until one survives. Needless to say, Kiyomaro becomes Gash's master, and through their many battles, Kiyomaro learns the importance of friendship and courage.

In a post-apocalyptic Earth, the water has become entirely toxic, except for some kept safe in a reservoir. A fortified zone has been created by a man named Sanga, he calls it The Lastland. A group of villagers have discovered safe water, and Sanga wants it. He and his band of killers go to kill everyone and steal it. As they do a mysterious man appears out of nowhere, instantly killing some of Sanga's men. His name is Kenshiro, and he can beat any man with his martial art, Hokuto Shin Ken. Sanga will do anything for the water, and Kenshiro will do anything to try and stop him. (Source: ANN)
