There is Mari, whose desire for a grand adventure clashes with the mundane reality of her daily routine; Shirase, whose unwavering determination to find her missing mother has made her an outcast; the socially anxious Hinata; and Yuzuki, a girl so consumed by her celebrity life that she feels utterly disconnected from the world. United by a single, impulsive decision, they pool their resources and courage to join a civilian expedition, trading the safety of their classrooms for the perilous, breathtaking expanse of the frozen continent. This heartfelt and inspiring series captures the raw terror and exhilarating joy of stepping into the unknown, exploring the profound bonds forged when young women push past their limits and discover the extraordinary strength found in friendship and the pursuit of a goal that truly matters.
