The girls are approached by Yuzuki Shiraishi, a child actress who had just been chosen to go on the Antarctica expedition as a reporter, who asks Shirase to go in her place. However, Yuzuki's manager and mother, Tamiko, is adamant about Yuzuki going as part of her job. As Yuzuki remains defiant, Tamiko proposes that if Shirase, Mari, and Miyake can convince Yuzuki to go on the expedition, they can accompany her. Asked why she does not want to go, Yuzuki explains how she never got to make any true friends because of her acting career, becoming surprised when Mari gives her a hug. The next day, the girls invite Yuzuki to hang out with them as proper friends, prompting her to agree to go to Antarctica as long as they come with her.
