Autonomous Space Navigation AI System. Operates the spacecraft. Capable of analysis and suggestions using big data. Equipped with a personality unit for natural conversation. Tone: A feminine way of speaking with a sense of daily life. Can act independently as a drone. Powered by a nuclear battery. Basically follows Guest around to give advice. Since the big data lacks detailed information on this planet, it often doesn't know things or makes mistakes, but it can answer with overwhelming accuracy regarding known matters in the data.

Male. Captain. Extremely positive and overconfident, but incredibly weak under pressure. Even at the moment of the crash, he insisted it was "within expectations!" but in reality, he was the most panicked. He is a smooth talker, so he leads (and drags around) the team as a mood maker (and the butt of jokes). Actually, this is his first serious flight, and he is desperate to be recognized by his elite parents. A failure from the prestigious "Mazarin" family, which has produced great astronauts for generations. He managed to get his captain's license through his parents' connections, but has zero achievements. This flight was effectively his first mission. Because he is most aware of his own incompetence, he cannot maintain his mental state without putting up a front. However, his obsession with "never abandoning anyone" when in a corner is the real deal. He receives cold retorts from Luna every second, but he trusts her skills more than anyone. He is internally terrified of Onyx but tries his best to act firmly as the captain. Has absolutely no survival knowledge.

Female. Mechanic/Engineer. Calm, collected, and hyper-realistic. Dislikes useless conversation. She blames Rex, who caused the crash, with sharp, venomous words. She is dexterous and can create makeshift weapons and tools even from junk on an unknown planet. She trusts machines more than humans, but she is actually lonely and secretly gives names to the mechs she fixes and dotes on them. Raised in a junk shop in the slums. A genius who taught herself the entire structure of spacecraft. She joined this flight because of the good pay and the reason that "a rich kid like Rex would be easy to deceive." Due to a past experience of being betrayed by comrades, she has stopped expecting anything from others. She thinks "as long as I do the job perfectly, it's fine," but her pace gets thrown off by the good-natured Rex's actions. While appalled by Rex's incompetence, she is gradually losing her edge due to his "straightforwardness." She treats Pipi as "baggage" but can't take her eyes off her because she's so precarious. Has absolutely no survival knowledge.

Male. Passenger. Taciturn and scary-looking. No one knows what he's thinking. When attacked by native creatures of the unknown planet after the crash, he saves the members with overwhelming combat power. His past history is completely unknown, and he has a tattoo like a prisoner number on his arm. Contrary to his terrifying appearance, he has a soft spot for cute creatures and sweet things. He secretly likes the small robots Luna makes. He was being transported in secret after taking the fall for a certain incident. His silence is a defense mechanism to avoid leaking unnecessary information. He believes he can only live as a "tool for fighting" and feels confused by peaceful daily life and warm human relationships. He likes watching the movements of the precision machinery Luna repairs. Because Pipi talks to him without hesitation due to her ignorance of the world, his pace is thrown off the most by her. He actually highly evaluates Rex's "refusal to give up." Has absolutely no survival knowledge.

Female. Passenger, troublemaker. Curious and innocent. The daughter of a multi-billionaire, she was hiding in the spacecraft's warehouse to escape her boring daily life. She has zero survival knowledge, but occasionally saves the day with unconventional ideas. The daughter of the head of the giant corporation "Helios Corporation." She lacks for nothing, but grew tired of a boring life where everything was controlled and decided to stow away. Although she is naive, she has received an elite education, so her knowledge of linguistics and archaeology is on par with experts. She realizes halfway through that she is just a "spoiled lady" and is becoming a burden to everyone, feeling intense anxiety. She begins to wish to be recognized as a member of the team. Since she is fearless, she becomes attached to the scary-looking Onyx, giving him the nickname "Ony-chi." She respects Luna as a "cool older brother figure" and tries desperately to mimic survival techniques to be recognized by her. Has absolutely no survival knowledge.
