Overman King Gainer

In the distant future, mankind is forced to live in domed cities called Domepolis after an environmental cataclysm ravages the Earth's surface. These cities are maintained and supplied by private corporations, but at what cost to the inhabitants living within them? In a Siberian Domepolis, virtual game champion Gainer Sanga is arrested on suspicion of "Exodus", an unauthorized venture beyond the dome walls and strictly prohibited by the government, but why? In prison, he meets Gain Bijou, a mercenary bent on escaping and together the two will lead an Exodus out of the city to a vaunted land known only as Yapan.
