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.
