In the Kingdom of Milos, where the royal bloodline has died out and a struggle to determine a new royal family is underway, a part of the kingdom, the sacred "Valley of Flowers," maintains its independence through the power of the "Flower Saint," who draws out the power of the divine flower "Rosa." However, Flower Saint Rutida suddenly loses control of her powers during her wedding to a royal candidate and is banished from the sacred area. Three years later, another royal candidate, Torfon, discovers Rutida living in an old monastery deep in the mountains—!?
