The idol industry is notoriously rigorous, but for individuals who can wield magic to elevate their performances, fame comes easily. With the public's strong preference for them, these idols are called "tier one," while those without powers are "tier two." One such unfortunate group is Star One. Despite having the financial support to propel them to stardom, they failed to manifest magical powers before becoming adults, causing even their company to lose faith in them.

As the tier two group struggles to remain in the limelight, an unidentified terrorist organization begins targeting and murdering tier one groups for reasons unknown. When Star One's ever-hopeful members—Soule, Eugene, Taho, Viken, and Avys—fill a last-minute vacant spot at a tier one idols' show, they find themselves in the eye of the terrorists' attack. As the situation escalates, Soule unleashes his magical abilities for the first time and saves everyone.

With this miraculous turn of events, the boys are given another chance to excel in the idol industry; they are assigned a capable trainer specialized in awakening and controlling one's magical powers. However, the terrorists suspect Star One to be "boys of destiny" fated to save the world—and swear on destroying them for good.
