Yumiko Samejima

Yumiko Samejima serves as the head chef aboard the private Antarctic expedition 'Antarctic Challenge.' Despite hailing from the subtropical island of Okinawa, she boasts a remarkable tolerance for freezing temperatures. Known for her candid, no-nonsense attitude and natural leadership, she initially harbored doubts about high schoolers joining the mission—yet she ultimately became the most steadfast and reliable guardian the young crew could ask for.
