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.
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...
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.
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.
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.
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.
