In the land of Kuruda, warriors with magical powers and incredible fighting skills battle for the ultimate prize: the title of Sevaar, the strongest warrior in the land. Elle Ragu, nicknamed Shadow Skill, is the newest Sevaar to emerge, but that doesn't make her life any easier. Teaching her "little brother," Gau, how to be a warrior, fending off assassins from other kingdoms and thwarting enemy invasions is hard enough, but her biggest challenge will be paying off her drinking debts.
影技的故事发生于一个叫做阿修利瓦纳的国家，阿修利瓦纳自远古以来就被一种神秘的力量保护者，又被称作圣王国。圣王国的中心是悬浮要塞圣都朱利亚涅斯，受到四王都的保护。所谓四王都，指的是北方的利奇多亚、西方的菲鲁西亚、东方的奇修拉那以及南方的克鲁达。在圣都朱利亚涅斯居住着圣女王莉鲁贝尔托罗比裘，圣女王直接接受圣力，肩负着圣国的存亡。故事中因为圣力的枯竭，莉鲁贝尔托罗比裘也重病不起，为了拯救阿修利瓦纳，不得不向同样继承圣力的月之女王月利珊布拉借助力量。
