With no more conflicts or catharses left to have, the girls enjoy their final days in Antarctica. They’ve settled into such a routine and gotten so used to the astonishing environment, one adult jokes they won’t be able to reintegrate into society, presenting Shirase and the other Mahjong junkies as evidence.
Their final journey to the frozen sea affords them the opportunity to taste snowcones made from ice with thousand-year-old air pockets, which Mari attests to be delicious. They also learn that much of the winter team’s activities will include sleeping, drinking, and games to pass the time.
Shirase finally gets her wish to be surrounded by adorable penguins, but she’s locked in a cycle of being disgusted by the smell and delighted by being in their presence while asking for some unspecified form of help. I imagine many of us would feel the same way.
Mari is getting cold feet about leaving, and wonders out loud to the others why they can’t just stay. Hinata flicks her forehead and doles out reality; they have to get back to their homes, their families, and their school. But all four promise that they’ll come back together someday.
They then present their final request to the rest of the team: that they play a game of snow softball. Captain Toudou is, naturally, the ace, but just like Takako, Shirase is not only able to hit her pitch, but drive it out of the “park.”
On the eve of departing, Shirase decides to have her hair cut short—her heart wasn’t broken by a guy, but such a change makes sense after her catharsis with the laptop (she also wisely chooses Hinata to cut it, not Mari). The whole team musters for the girls’ farewell ceremony, and after a heartfelt speech by Gin that starts everyone crying, Shirase confidently delivers and even more heartfelt, tear-jerking speech.
In it, she expresses the understanding she reached in this place beyond the universe, and why both her mother and her love it so much: It’s a place that strips everything bare, with nothing to protect you and nowhere to hide. It’s a place where someone can come face-to-face with who they really are…and she did that.
Before embarking for home, Shirase hands Gin her mom’s laptop, stating she no longer needs it. Later, Gin discovers there’s still a message from Takako in the outbox; the last she ever composed. The quartet waves goodbye to their Antarctic summer home where they experienced and learned so much about the world, each other, and themselves.
Yuzu wonders if maybe they all got a little stronger during the journey. A ‘little’? I think she sells herself and the others short here. They were the first high school-age students to explore Antarctica, and they made it. Now, all of a sudden, they’re headed back to the normal world. Even if and when they come back, it will never be the same as their first time.
When night falls, Mari finally gets to experience the one thing they couldn’t due to the laughably short Antarctic nights: view the aurora. Just when they do, Gin sends the last email Takako wrote to Shirase, stating how the real thing is “ten thousand times more beautiful”—something of which, in that moment, Shirase and the others are all to aware.
The four friends, having forged their bonds in the coldest and harshest crucible on the planet, go their separate ways with confidence and return to their lives that were with a serious sense of accomplishment, self-awareness, and maturity.
They discovered as much about themselves in Antarctica as they discovered about the place itself, like how there are no “nothing” days but there’s still more to discover upon returning, like the smell of one’s house.
And in a perfect capper to a marvelous series, Mari texts Megumi that she’s home, and gets a near-immediate response, along with a photo of her posing with the aurora: “Too bad. Right now, I’m in the Arctic.” Well played, Megu-chan; well played.
