When the manager of Kazuki, Japan's hottest pop star, approaches Benjamin Blume, manager of the fledgling rock 'n' roll band Hayate, he can't believe their good fortune. Their plan to court publicity by having Hayate's lead singer, Kaji, pose as The Shining One's lover sends both groups' popularity skyrocketing.  But when the publicity stunt turns into a real affair with disastrous consequences, Kaji is left heartbroken. Unfortunately, Ben has problems of his own. Soothing his lead singer's pain and keeping Hayate on the road to success becomes even more challenging when his ex-lover, rock god Hagen Rune, shows up promoting rival band Voodoo. Torn between the attentions of Kazuki's attorney, Shin Yoshiro, and the feelings for Rune that have never quite died, Ben's decisions could send Hayate to the top of the charts—or lead to disaster for them all.
