Possessing memories of an alternate modern era, he successfully pilots a prototype mech that no one else has even been able to activate. When Keita is suddenly deployed to the battlefield, he uses the knowledge from his previous life to achieve results that defy all established norms. Thus begins humanity s battle to reclaim the world.
