The people of Lingalind revere the wall as a god, believing that all of existence is contained within and that the wall protects and provides for its inhabitants. While the land consists of several territories, it is mostly dominated by two powerful nations: The, which values intelligence and diplomacy, and The, which values honor and strength. These two nations are in constant conflict with each other over obtaining land and capsules, which are sent from an unknown location once per month and land in predetermined regions of Lingalind, containing provisions and weapons that the people of Lingalind consider gifts from the wall. Some of these capsules contain devices known as Bind Warpers, metallic armbands that allow one to summon and control a giant mechanical armor known as a . A Briheight's appearance and abilities are tied to one's, the thing they believe in above all else. Conviction is also recognized as an energy that flows throughout the world, powering various forms of advanced technology found within Lingalind and granting some people special abilities outside of operating a Briheight. Being defeated in battle while controlling a Briheight causes the user to disappear.

Inside is an amnesiac young man whose only memory is that he is from "beyond the wall." Taking the name "Back Arrow," he seeks to journey back over the wall to restore his memory, entangling himself in the conflict between the two nations.
