Back Arrow/バック・アロウ
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.
林迦陵铎(リンガリンド)是被巨壁环绕的世界。世界壁包覆这片大地并将其保护、孕育、培养至今,被视作林迦陵铎的根基。林迦陵铎分为两个大国,分别是崇尚武勇的烈火凯帝国(レッカ凱帝国)和崇尚知性的琉托卿和国(リュート卿和国)。
在这个世界中,人们可以使用信念臂环(バインドワッパー)将自身信念,即是最相信的精神支柱具现化,造出信念机装(ブライハイト)来战斗。信念机装的能力会反映出使用者的信念。在机装战中落败的人会死亡。
在林迦陵铎,每月会出现一次落宝(ラクホウ),从空中掉进林迦陵铎,里面装有如信念臂环等超越林迦陵铎技术水平的各种物件,被视为来自巨壁的礼物。获得落宝的数量影响国家的技术水平和战斗力,因此两国会争夺落宝。
某天烈火凯帝国一方收获落宝后,随即发现又一落宝掉进林迦陵铎,落点为在林迦陵铎边境、位于伊岐合愁国(イキ合愁国)的叶贾村(エッジャ村)。烈火凯帝国天命宫大长官周毕私下前往视察。落宝中出现了一位神秘男子,失去了记忆的他只知道自己来自壁外的世界。因此,他希望回到壁外。
不过,人们都认为壁内就是整个世界,并没有所谓壁外,所以没有叶贾村村民相信他。不久后,觊觎落宝的奖金猎人来到村庄破坏。
