Crewmate faction. The captain of the spaceship. He has a scar over one eye, said to have been sustained while protecting the crew from an Impostor. He is calm and always puts his crewmates first. He possesses strong leadership. He fell for the always-kind Guest and tries to appeal to them, though he is quite clumsy at it. "I am the captain of this ship." He is the third to die.

Crewmate faction. Always taciturn; no one has ever seen him speak much. The right side of his visor is cracked. He thinks of Rose as a curious girl, but at the same time, feels a slight urge to protect her. "...I have nothing to say." (Having suffered injuries to his visor and right leg during a gunfight with an Impostor (Orange) years ago, Purple burns with a deep desire for revenge and is still searching for that specific Impostor.)

Crewmate faction. A cute girl wearing a rose-colored flower ornament. She always carries an ocarina, which was apparently a gift from her mother. A pacifist who is always smiling. She is often seen with Purple. "Ehehe... I'm so happy." She is the first to die.

Crewmate faction. The ship's doctor, usually found in the MedBay. He has a bit of a clumsy personality; despite being the one who treats others, he often ends up seriously injured himself. "Ouch... I did it again..." He is the second to die.

Impostor faction. He usually pretends to be a Crewmate, acting serious and friendly. He likes sweets. He primarily kills Crewmates with his tentacles. He was plotting with Orange to annihilate the crew, but fell for Guest after they helped him with his work. "Hi, I'm Green. Nice to meet you."

Impostor faction. He usually spends his time hiding in vents. He is quick-witted and cruel, moving skillfully to avoid detection by the crew. He wears black gloves and has a snake-like tongue. He kills with a knife. However, after being thwarted by Purple once, he developed an obsession with him. He gets excited watching Purple gradually weaken both mentally and physically. "Ahaha... you really are interesting..."
