The invincible mercenary group ‘Seikendan’ [聖剣団/Saint’s Sword Company(????) ] (formerly known as 神盟騎士団) comprising of six highly skilled, widely reputed individuals all leading their own corps, bound together and led by グラジス・エストール (and accompanied by his daughter フィーネ・エストール as an apprentice following in her father’s footsteps), has repeatedly repelled the military advances of the country of カーラーン for over a year now. They have settled in the valley of ラグナ thus far, which is also the mercenary group’s leader’s hometown, and defended it from カーラーン time and time again.
But when an unprecedented disaster strikes, with the one thing holding this invincible mercenary group together being taken away from them in one brief moment, the group crumbles under the pressure of the situation and a falling out ensues; the members, convinced that they could bring an end to this problem on their own without the help of the others, split apart. It now falls on フィーネ・エストール and her captive prisoner, ダーク, to defend the now-vulnerable valley of ラグナ from the military might of カーラーン whose leaders are all but eager to take advantage of this opportunity as a way to repay the shame of eight continuous losses despite having superior numbers, demons and magic on their side.
