Overman King Gainer

Gainer Sanga, a skilled gamer from the Siberian Dome-polis, and Gain Bijou, a mercenary, hijack an Overman to escape the dome city. The Overman is used to transport a large group of people out, amidst the post-environmental disaster world outside where humanity is trying to recover. Gainer and Gain's plan is a response to the harsh living conditions within the domed cities, where people are struggling to survive.
