Plot
In 1999, the world has been reduced to an apocalyptic wasteland due to an inexplicable gust of wind that wiped even the most basic memories, such as speech and civility, from the minds of the world's populace. Wataru befriends a young man named Johnny who, prior to the incident, was part of a government experiment designed to expand the memory capacity of the human mind and, therefore, was able to retain his memories. Johnny helps Wataru regain his speech and teaches him other basic functions. However, as a result of the physical toll his body endured due to the government experiments, Johnny dies after encouraging Wataru to travel the world.
Wataru encounters a strange woman named Sophia after she helps him escape from an encounter with an unmanned Police Mech Unit and agrees to take Sophia to New York City. Together the two travel to Los Angeles where they help save Sue and her father, Little John, from a mob. Sue was to be offered as a bride to appease a "god", which in reality is a Construction Mech controlled by a man, but fled to escape her fate.
