Nearing their first debut anniversary and with their popularity still on the rise, IDOLiSH7 set a date for a live tour to express their gratitude toward their fans. Meanwhile, the Black or White event draws closer—and as the previous year's winners—the group must prepare to take on the challengers. Looking to solidify their reputation in the world of idols, IDOLiSH7 are determined to come out victorious and settle the score once and for all with their rival, TRIGGER. While working around their packed schedules, IDOLiSH7, TRIGGER, and Re:vale meet powerful figures in the entertainment industry. In the midst of the hectic period, some members catch wind of a scandalous rumor regarding IDOLiSH7. As the members of IDOLiSH7 begin to worry about their image, their bonds are put to the test, all while a spiteful figure begins to carry out a certain plan behind the scenes.

IDOLiSH7 is more successful than ever, but no one is smiling because a new threat has taken the stage: the debuting idol group ŹOOĻ. Managed by the nefarious entertainment executive Ryou Tsukumo, they will stop at nothing to get their way, resorting to all kinds of underhanded tactics to bring down their rivals. TRIGGER's image has already been ruined by scandal, and IDOLiSH7 and Re:vale are headed for the same fate—or worse. Meanwhile, Zero, the legendary idol who disappeared 15 years ago, continues to haunt the present through those he left behind. His manager seems to be in contact with Tsukumo for his own schemes, and Zero's songwriter reveals himself in a letter after having been missing for years. IDOLiSH7 finds an ally in Re:vale to thwart ŹOOĻ's plans while trying to make sense of Zero's colleagues' actions, but it may be impossible for everyone to emerge unscathed.

After the death of Saizou, Kabamaru's horribly strict grandfather and Iga ninja teacher (sensei), an old lady, Ran Ookubo, claims that she received a letter from him asking her to take care of his grandson. So Kabamaru runs off with Lady Ookubo to the big city Tokyo to gorge on yakisoba, ramen, chow mein, and attend a regular school—which turns out to have weird quirks of its own. (Source: ANN)

The VENUS Program is an idol scoring system that is entirely impartial, using AI and data to rank candidates based on an array of factors. To determine the rising stars of the idol industry, the annual VENUS Grand Prix is held utilizing these algorithms. Among all the idols that have participated, none have been as outstanding as Mana Nagase. However, on the day of the tournament's finals, a tragic accident suddenly ends her career. Kouhei Makino, who previously 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 tutelage of her former advisor. Also auditioning is Sakura Kawasaki, whose voice sounds astoundingly 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 traverse through the unforgiving world of idols.
