Along with interviews with the staff of 765 Production, the idols themselves are also interviewed over why they became idols and what their goals are.
After seeing the girls' current profile pictures, the Producer thinks that they need new ones and orders a re-shoot so the girls can make better impressions in their auditions.
The Producer and the girls head to the town of Furusato to perform a small concert at the local Summer Festival, but it doesn't turn out as they all expected. Yukiho and the Producer both have to face their fears.
It's summer, but the studio's air conditioner is broken. So the Producer agrees to bring the girls to the beach for a vacation while the air conditioner is repaired. Ritsuko gets a go on the new idol unit she created.
Ritsuko's idol unit, Ryuuguu Komachi, with Azusa, Iori and Ami as its members, becomes popular after their debut and gets booked in many gigs, including singing on a music television program. Worried over the other idols' popularity, the Producer decides to have the idols audition for several gigs.
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.
As the day of the concert gets closer, the Producer and the idols are worrying about Miki, who hasn't come for practice sessions for the past few days, which Ritsuko explains as being caused by a misunderstanding over Ryuuguu Komachi.
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 Takagi, the idols have become very popular to the point of having to wear disguises in public.
