On earth, a terrible conflict was happening. For control of the planet, the forces of light and darkness engaged in battle. The Earth was covered in darkness by magical objects known as Darkbring. But by burning these relics, one valiant warrior prevented the destruction of the planet. A tenth of the Earth was destroyed after the last stone was shattered in an enormous explosion that became known as OVERDRIVE. After more than 50 years, a shadowy group called Demon Card is now attempting to seize power. Haru, a sixteen-year-old, must fight this evil entity off with the aid of his pals. How well will they work together?
