The world of Lingalind is surrounded by a mystical wall with seemingly nothing beyond its confines. Worshipped as the mother of the land, the wall delivers celestial gift capsules called Rakuho'' to locations across the continent. Arriving once a month, the capsules contain metallic armbands that allow the wearer to transform into a mechanical being known as a Briheight. As a result, Lingalind is thrown into constant turmoil by its warring nations, all hoping to strengthen their military prowess by procuring the offerings for themselves. One day, a Rakuho crash-lands in the countryside with an unexpected inhabitant—a mysterious black-haired man. All eyes are set on this strange newcomer, who calls himself Back Arrow, when he claims to have hailed from a place beyond the wall—a revelation that can potentially unravel Lingalind's entire dogmatic foundation.

Two and a half years after the dark day of the Lost JuLai, Meryl Stryfe roams in the desert wilderness of Noman's Land alongside her younger assistant, Milly Thompson. She still pursues Vash the Stampede, the culprit behind the cataclysmic events that took the lives of 90 percent of the JuLai city population. Vash, also referred to as the Humanoid Typhoon, is now sought after for 60 billion double dollars—the largest bounty in the history of the planet. In a backwater town of Noman's Land, an apathetic Vash has been rescued and cared for by Hoppered the Gauntlet, a man who covers his mutilated body with armor. But Hoppered's secluded life is abruptly interrupted by the arrival of young Jessica seeking help for her endangered home.
