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.　　影技的故事發生于一個叫做阿修利瓦納的國家，阿修利瓦納自遠古以來就被一種神秘的力量保護者，又被稱作聖王國。聖王國的中心是懸浮要塞聖都朱利亞涅斯，受到四王都的保護。所謂四王都，指的是北方的利奇多亞、西方的菲魯西亞、東方的奇修拉那以及南方的克魯達。在聖都朱利亞涅斯居住著聖女王莉魯貝爾托羅比裘，聖女王直接接受聖力，肩負著聖國的存亡。故事中因為聖力的枯竭，莉魯貝爾托羅比裘也重病不起，為了拯救阿修利瓦納，不得不向同樣繼承聖力的月之女王月利珊布拉借助力量。
