In Lingalind, there is a mystical wall surrounding it with nothing else on its borders. This wall is considered sacred and is believed to be the mother of the land. Every month, celestial gift capsules called "Rakuho" are delivered to various locations across the continent. These capsules contain metallic armbands that allow wearers to transform into mechanical beings known as "Briheight." Due to this transformation ability, Lingalind is constantly plagued by warring nations seeking to acquire these offerings for their own military advantage. One day, a Rakuho lands unexpectedly in the countryside with an unusual passenger - a mysterious black-haired man who introduces himself as "Back Arrow." He claims to have originated from beyond the wall, which has the potential to challenge Lingalind's entire belief system.
