Shown from a perspective of a cameraman shooting a documentary, it films and introduces the girls of 765 Production studios and their everyday activities as an idol. Along with interviews with the staff of 765 Production, the idols themselves are also interviewed over why they became idols and their goals.
After seeing the girls current profile pictures, the Producer decides that they need new ones and orders a re-shoot so the girls can get a better impression in their auditions. The younger idols, Iori, Yayoi, Ami and Mami want to look more mature, which they fail to do so. After some help of Azusa, Miki, Ritsoku and the producer, their photoshoot becomes a success.
Iori humiliates herself on live television when she forces an interviewer at the Minase estate to focus on her rather than ask about her father and older brothers. The Producer reprimands her actions, but Iori ignores his advice. Yayoi invites Iori and Hibiki to her home to have dinner with her five younger siblings where Iori learns about the life of a 'commoner' and gets to know Yayoi's brother and the eldest boy, Chousuke, who wants to help his sister.
After finishing filming a TV mystery mini-drama, Ryuuguu Komachi and Ritsuko return to 765 Production studios for a break with Mami and the Producer returning as well. Iori decides to treat everyone to some special puddings she bought earlier, but finds out the puddings are gone from the refrigerator. Suspecting the other idols as the culprits, Ami and Mami decide to solve the mystery by playing detectives.
The Producer informs the girls that their big break has come as they will be performing live at a 765 Production thank-you concert. Despite its main event being Ryuuguu Komachi, the girls are excited since they will be performing a new song and dance routine. However, the girls have to go through tough dance and vocal lessons, which some of the girls are having problems doing correctly, especially since their exams are coming out.
It's the day of the 765 Production thank-you concert, but complications arise for Ritsuko and Ryuuguu Komachi when a typhoon hits the city. All transit trains are stopped, forcing Ritsuko and the others to drive to the concert, only to get into a traffic jam. With the audience already having arrived at the concert, the Producer issues a change of plans to the backstage crew and the idols to have them perform first to buy enough time for Ryuuguu Komachi to arrive.
Ever since the concert and an article by Yoshizawa, a famous reporter who is a friend of President Junjirou, the idols have become very popular to the point of wearing disguises in public. After appearing on a TV show and going back to their makeup room, Haruka and Yayoi encounter Jupiter who's leader, Touma Amagase gives them an ominous warning. Back at 765 Pro studio, everyone is waiting for a magazine which features a photo shoot of the idols on the cover but Iori brings it, showing instead Jupiter on the cover. Wanting to know wants going on, President Junjirou and Yoshizawa believes this was the work of 961 Pro studio President and Jupiter's manager, Takao Kuroi, who used his connections to have the magazine cover changed. Kuroi and Junjirou were once friends in the idol industry but both of them had a falling out because Junjirou disapproved of Kuroi's methods. Because of the 765 Pro idols recent popularity, Kuroi wants revenge against Junjirou by crushing his idols using Jupiter. The girls want revenge but the Producer, Ritsuko and Junjirou tells them they shouldn't fight dirty and stoop as low as Kuroi and if they wish beat him, they should do it fair and square. As the idols are still upset over the magazine cover, Haruka helps Kotori arrange their fan letters which the others later joined. Thanks to the encouraging letters from their fans, the idols realize it is their fans that should be winning over rather than their rivalry with 961 Pro and all of them agree to work hard for them.
It is the Christmas season and Haruka wants to celebrate a Christmas Eve party with everyone at 765 Production, just like last year. But with the idols' new fame, all of the girls are busy attending and performing at TV shows, variety shows, holiday or Christmas specials on Christmas Eve. Most of them might not make it in time...
The Producer manages to survive his accident but remains hospitalized for a while. As a result, Haruka returns to musical rehearsals to channel her grief into her role and wins the lead from Miki. Desperate to get the idols together, Haruka asks Ritsuko to reschedule or cancel her current gigs so she can practice for the New Year's concert.
The idols of 765 Production continue on their neverending journey—towards a new stage, towards a bright and shiny future! The girls and their producer have gone through thick and thin, and have stood face to face with all kinds of difficulties. It's time again for the girls to foster their friendship, and through great discipline, they step forward to their starry future.
