The franchise centers on "Starlight," a dance and dance troupe beloved the world over. Karen and Hikari promised each other when they were little that one day they would perform together on that stage. Time passes and now they are both 16 years old. Karen is very excited about the dance lessons she takes every day, keeping her promise close to her heart. Hikari changed schools and now lives far away from Karen. But the gears of fate bring them together again, destined to meet again. The two, along with other hopefuls, will compete in a mysterious audition to become part of this great company.

The stage emulates life and compresses it, setting free skills learned over lifetimes in brief but dazzling displays for the amusement and judgment of others. For the performers, it is the ultimate risk, and some will rise while others must fall. Nowhere is this truer than at the Seisho Music Academy, where music, dance and real weapons all come into play in the creation of the next great Star. Karen and Hikari’s destinies have been linked since a childhood promise, but their journeys here have taken very different paths. Now, after Hikari leaves, Karen must discover who she is without her opposite, while Hikari must rediscover her own course. Nor are they the only girls who must reassess and change if they want to achieve their dreams, as the dance, magic, and swordplay continue!
