After several decades of constant warfare, the West Federation has brought about a time of forced peace thanks to SEMCADs. Sky and Earth Military Class Automaton Device, these large humanoid machines that use unmatched combat capabilities and revolutionary technology to protect the only world superpower on earth. In this period of peace we follow Spencer Parid, a new recruit looking to join the West Federations SEMCAD unit with two other members, Lucas and Issac. How long can this peace last? Even a secret as well kept as the inner workings of SEMCADs has to be discovered by the rest of the world eventually, and when this happens, only the future can show who will end as the victor.
