Mari Tamaki is a second-year high school student looking for something to pursue. She meets Shirase, a classmate who is often seen as odd and has few friends. Shirase is known for constantly talking about Antarctica and is nicknamed "Antarctic" by others. Inspired by Shirase's passion, Mari decides to support her, even though it seems improbable that high school girls would ever travel to Antarctica.
