It's been several months since their training, and the girls' trip to Antarctica is drawing near. With Rin's help, Kimari manages to sort out her luggage, and in doing so, finds a game she borrowed from Megumi a long time ago. When she visits her friend to return it and talk about old times, though, Megumi doesn't seem to remember it at all...

At last, the girls have arrived in Antarctica, and are awed by the scene before them. No one's been at Syowa Station in three years, so there's a lot to do to get it cleaned up. As the girls keep themselves busy, Yuzuki seems to make up her mind about something.
