Spheres

A forgotten civilization known as the Kingdom of Spheres once existed on Earth, its people possessing abilities that would now be considered psychic. As class divisions grew, the kingdom fell to those seeking power. Na Yeon, a girl discovered in Antarctica after the kingdom's downfall, becomes a target of Asten, the ambitious leader of the Sphere Union, who sends agents to monitor her. Na Yeon and her companions work to protect three artifacts—objects believed to hold the power to dominate the world—from being seized by the Sphere Union.
