With he invasion of monsters called Magatsuhi, the world is in the brink of extinction. Having lost the majority of its forces, instead of Self Defense Military forces the ones in charge of protecting the westernmost of mainland and also functioning as front's Fortress are the mercenaries of the Private Military Company, known as "The Self-Defense Organization of Far-Eastern".
