The VENUS Program is an idol scoring system that is completely impartial, employing AI and data to rank candidates based on a variety of factors. To identify the rising stars of the idol industry, the annual VENUS Grand Prix is held using these algorithms. Among all the idols who have participated, none have been as exceptional as Mana Nagase. However, on the day of the tournament's finals, a tragic accident abruptly ends her career. Kouhei Makino, who formerly worked as Mana's manager, continues his career at Hoshimi Productions years after her death. Wanting to build a new team of idols, he accepts interviews from various girls. Unexpectedly, one of the interviewees is Kotono Nagase, Mana's younger sister, who is striving to carry on her sister's legacy under the guidance of her former advisor. Also auditioning is Sakura Kawasaki, whose voice sounds remarkably similar to that of Mana. Both Kotono and Sakura pass the evaluations, joining a group of eight other aspiring young girls. Living in a shared dormitory, the 10 members work together to learn more about what it means to harmonize as a team. United by an ambitious endeavor, the girls compete their way to the top as they navigate the unforgiving world of idols.
