Synopsis
In Idol☆Sister, Ayaka Takano, Maki Kamii, and Maina Ooizumi, all former members of the idol group IKB31, have reunited to form a new unit called Platinum Kiss. Their success depends heavily on their manager, who is also Ayaka's older brother, despite his rather perverted nature. As their upcoming concert approaches, the girls become anxious when their manager informs them he might not be able to attend. They search for him frantically, only to discover he has been secretly watching them all along. With only an hour left before their performance, he steps in to help them "relax."
