Description
Nobue Todoroki is a geologist assigned to the civilian Antarctic observation team that serves as the backdrop for the story. She is part of the Rock team, responsible for geological research and field work on the continent. Her role in the expedition is that of a supporting crew member rather than one of the main protagonists, but she interacts with the four high-school girls—Mari Tamaki, Shirase Kobuchizawa, Hinata Miyake, and Yuzuki Shiraishi—during their stay in Antarctica, sometimes guiding them on missions such as placing geodetic markers and painting rocks at Rundvågshetta or pointing out sea ice near the ship.

Nobue’s personality is defined by a persistent lovesickness and anxiety over the long separation from her boyfriend, whom she calls Yu-kun. She is frequently seen checking her phone for emails or calls, and when she goes several days without a reply, she becomes unable to concentrate on anything else, even breaking down in tears during a call to him while the ship was docked at Fremantle. This emotional vulnerability contrasts with her professional competence as a geologist, showing that she is both dedicated to her work and deeply affected by the personal cost of the expedition.

Her primary motivation is the same as that of the entire civilian observation team: to carry out scientific research in Antarctica. However, her personal arc is centered on managing the strain of being away from her partner, which gives her a relatable, human quality. She does not undergo a major transformation over the course of the series, but her willingness to help the younger characters, despite her own distractions, demonstrates a dependable and kind nature.

In terms of relationships, Nobue’s most significant bond is with Yu, though he remains off-screen. She shares a collegial rapport with the other expedition members, and she acts as a helpful, if occasionally distracted, mentor to the four girls, supporting their Antarctic adventure without becoming a central figure in their personal dramas. No notable supernatural abilities are present; instead, her notable skill is her expertise in geology, which contributes to the team’s scientific mission and directly assists the characters in completing tasks on the ice.
