In the world of idols, the VENUS Program functions as an impartial ranking system driven by AI and data analysis. This system is used each year in the VENUS Grand Prix to identify the next generation of star idols. Among all participants, Mana Nagase stood out as the most exceptional. Tragically, her career ended due to a fatal accident during the final round of the tournament.
Years later, Kouhei Makino, who once managed Mana, remains at Hoshimi Productions. Aiming to form a new idol group, he holds auditions and encounters Kotono Nagase, Mana's younger sister, who is determined to carry on her sibling's legacy with the help of her former mentor. Another applicant, Sakura Kawasaki, impresses Makino with her voice, which eerily resembles Mana's.
Makino selects Kotono and Sakura, along with eight other hopefuls, to form a group. Together, the ten girls live in a communal dormitory, learning the intricacies of teamwork and striving toward their ambitious goals. They face the challenges of the competitive idol industry as they pursue success.
