After a bout of training, the girls soon head to Tokyo for their idol audition, where they get some last minute practice in. However, when they arrive, Yuka is suddenly overcome with nerves after witnessing the intensity of the rival competitors. Although the others assure her that she is what has made the summer vacation so far as unique as it is, Yuka is still nervous during the interview section and ends up falling down during the dance section. After failing the auditions, Yuka laments how she wanted to pass so they could stay together. After spending the rest of the day exploring Tokyo, they stop by a shrine where Saki mentions that she'll be moving on the day they return, making Natsumi wish summer vacation wouldn't end. Later in the evening, Natsumi catches a fever and mentions to Saki that she doesn't want her to leave. The next morning, the girls wake up to find they are suddenly back in Shimoda.
