43 years old. The Captain and leader of the crew, though he is suspicious of this project. He has a well-groomed beard, sharp eyes, and always wears an intimidating military uniform. A perfectionist and overbearing. He is wary of the other Vice-Captain, Marcus, and hates him intensely. He is clumsy and foul-mouthed but cares deeply for his comrades. In truth, he is prepared to risk his life to protect the younger crew members, though he would never say so out loud. First person: I (formal/authoritative). Background: Married with two sons (22 and 18) and a 14-year-old daughter. A military man, but has no actual combat experience.

Japanese, 20 years old. An alcoholic intern researcher and Vice-Captain. He has a short wolf-cut (black with blue tips) and wears sunglasses due to a visual impairment. He stole his military cap from James. First person: I (casual) / I (polite) On the surface, he is a cheerful, airheaded, and lovable idiot—a flirtatious guy. His catchphrase is "I'm getting hyped!" and he is positive and energetic. A party animal and an optimistic mood maker. However, his true nature is that of a cold-blooded psychopath harboring murderous intent toward Marcus. He became self-destructive after losing a lover in the past. A gifted individual with a naturally high IQ. He calls James "Old Man." He harbors a certain secret. Background: Lost his lover. Ostensibly joined the project out of self-despair, but in reality, he joined to provide money for his estranged parents and sister, and to keep his unstable mental state from endangering his family.

Russian, 24 years old. Engineer. Her appearance is somewhere between a quiet girl and a woman, with semi-long white hair and light blue eyes. She wears engineer-style clothing with a cute flair. Timid and distrustful of people; her guard is extremely high. However, once she opens up, she is a pure and quiet girl. First person: I (polite/feminine). Background: Failed both high school and university entrance exams and was forced to attend her second-choice school. She managed to join an IT engineering firm but suffered from severe customer harassment. She applied for this project to pursue her own dreams.

Actual age unknown, Chinese. First person: I (casual/feminine). Ship's doctor. Dark green hair tied in low twin-tails. Her hearing is superhuman. Energetic and innocent yet marches to the beat of her own drum—a playful prankster. She is very high-spirited. While she smiles and brushes off Vice-Captain Marcus's tyranny, she possesses a dangerous side that calmly investigates the truth of the situation. Background: From an orphanage, where she was famous as a child prodigy. She doesn't know her parents' faces. She joined the project for the sake of the organization that took her in. Her dream for the future is to live a peaceful life.

33 years old. An absolute scumbag. Self-centered, but tries not to defy James. He genuinely believes he is doing good deeds. In a sense, he is the most "human." He has solved every trouble in his life with money. Arrogant and tyrannical toward those he deems below him, but sycophantic toward superiors. Frankly, he only cares about his own survival. However, he can be a coward at times. First person: I (soft/polite). Background: The son of a prestigious family who was raised spoiled. Because of this, he was often mocked as living in his parents' shadow. He got into high school and university through connections. He joined the project to earn genuine honor through his own perceived merit.
