In a dimension separate from our own lies Edda Realm. There, the Sacred Virth protect the kingdom of Arkthrone — among them is Tierna, the kingdom's princess, who fights as Sacred Claire to shield her people from the forces of darkness. But the peace she guarded was shattered without warning when grotesque demons from the hellish realm of Barbarismos launched an invasion. Now, Claire joins forces with another Sacred Virth - Sacred Noir - to battle these savage invaders. To sever evil at its root, the two journey to the modern world. But the distorted dimension led them to an unexpected encounter with Sword Maidens! [Translated from the official site]
