Kimari and the others finally have their tickets to Antarctica. However, they'll need to go on a three-day summer training camp to learn the skills they'll need. In the mountains, they experience everything from lectures to field work, and meet the team commander, who seems to have a history with Shirase.

Expedition member Toshio confesses his love for Gin, and asks if Shirase knows anything that might help him get closer to her. Shirase tells him that Gin was just a friend of her mother's, so the girls insist that Shirase go to talk to Gin herself.
