OVERMAN King Gainer

In a future where environmental disaster has driven humanity into enclosed cities known as Domepolis, corporations manage these settlements while imposing strict conditions on residents. Gainer Sanga, a top virtual game competitor in a Siberian Domepolis, is detained for suspected Exodus, the act of leaving the city without authorization. While in custody, he encounters Gain Bijou, a mercenary determined to escape. The two conspire to steal an enigmatic Overman from Duke Medaiyu's estate. As they evade the Siberian Railway Patrol, they embark on an Exodus toward Yapan, the ancestral homeland of their people.
