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. As everyone enjoys their time, office clerk Kotori Otonashi receives an important call from President Takagi back at the studio. Come nightfall, the Producer and the idols stay at a local inn where they enjoy a barbecue, have an outdoor bath, and play games. As everyone goes to sleep, Haruka, Chihaya, Makoto and Iori have some small talk about their vacation and where their careers might be in a year. After the vacation, President Takagi makes an announcement about his approval of Project Ryugu Komachi, produced by Ritsuko.
