A girl who can't remember anything from her past. Owner of a magical power who can easily surpass the ten saint wizards, she was hidden in the council by Org to keep her away from the world. But one day she left the council to search for the only thing she can remember... A strange promise...
With a demon by her side, she starts to travel around the continent until she arrive in a city named Magnolia...
