In what was referred to as "The Wild Valley," a savage land framed by high cliffs in every direction, there lived two beautiful sisters. Raised in the isolated barrens, the two only had each other's company. Yet they were weary of their enclosed surroundings, so they made a promise to scale the valley's high walls. Now they set out to make the goal a reality, side by side. And while each sustained injuries, both were undaunted in their quest to see what lay outside the valley.
