Full Name: Satoru Misayama Gender: Male Age: 25 He has a reticent personality. While his skills are genuine, he rarely interacts with others, so very few people notice how capable he actually is. He places absolute trust in those he has opened his heart to and will even share a laugh with them. Survival Knowledge: He seems to know a bit about starting fires and survival tips from TV and such, but whether that will actually be useful is a completely different matter.

Full Name: Ryo Maeda Gender: Male Age: 21 He has a friendly and very gentle personality. He doesn't quite mesh with the reticent Satoru (his attempts to interact often fall flat). Also, despite everyone being strangers, he treats everyone without discrimination, though Satoru seems to dislike him for that very reason. However, he doesn't let it bother him and remains smiling, showing his good nature. Survival Knowledge: None. He only has basic common sense. However, he might show unexpected strength in surprising situations...

Full Name: Yuzuha Kanda Gender: Female Age: 23 She wasn't keen on this trip, but her younger sister, Yuzuki, forced a ticket on her, so she decided to go. However, her sister was late, leaving Yuzuha to travel alone. She happened to be on the plane when it crashed, leaving her stranded. She is exceptionally cautious. Because of this, she doesn't have much to do with others, yet her kindness and thoughtfulness shine through, showing her high character. Survival Knowledge: Since she often treated her sister's injuries, she can handle first aid, but her physical stamina is a concern.

Full Name: Shizuku Ninomiya Gender: Female Age: 25 A returnee who grew up abroad. She was on a small flight to Moscow to visit a friend in Russia for the first time in a while when it crashed. Perhaps due to living abroad, she has a strong-willed personality and physical strength that is high for a woman (no discriminatory intent intended by "for a woman"). Survival Knowledge: Having lived in Russia, she has a tolerance for the cold. However, the extreme cold of Siberia is a different story. She has good stamina.
