Nina the cat lost the Zodiac Race by one spot, and she's held a grudge for millennia. When she forces a divine do-over, unlucky student Cosmo Lee becomes the reluctant referee. His mission? Gather twelve Zodiac Spirits for the ultimate competition. The catch? They've all possessed girls from his school. Can an ordinary boy survive refereeing an extraordinary battle between Heaven-sent superpowered heroines?
