Shirase is unsure how to feel when she is invited to join the others on a snowcat ride to where Takako was last heard from, fearing that there will be nothing left for her once she goes. After hearing Gin's reasons for coming to Antarctica despite knowing that Takako is dead, Shirase reminds herself of the effort she put in to earn the money she saved before deciding to join the others on their mission. As the team spend the night in the middle of a blizzard, Shirase hears from Gin about Takako's final words before Mari gives her her thanks for taking her to Antarctica. Upon arriving at a site for an observatory, Mari and the others search for proof that Takako was there, managing to find a laptop belonging to her. Logging onto it, Shirase breaks into tears as it retrieves all the e-mails she had sent to Takako that never got to be read.
