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.
ついに７６５プロ感謝祭ライブの本番の日がやって来た。はじめての大規模なライブに、興奮と緊張を隠しきれないアイドルたち。ところが、地方のイベント先から駆けつける予定だった竜宮小町のメンバーと律子が現れない。なんと台風による暴風雨で、新幹線が運休になっており、本番に間にあうか分からないという。緊急事態に不安を隠せない７６５プロのメンバー。果たしてライブを成功させることができるのか…！？
드디어 찾아온 765 프로덕션의 첫 라이브날.
하지만 라이브의 메인인 류구코마치가 지방에서 태풍 때문에 발이 묶이고 만다.
어떻게든 류구코마치가 도착할 때까지 시간을 벌려는 765 멤버들. 그 중심에는 미키가 있었다.
