Name: Fyune Ilsareel Affiliation: 7th Earth Investigation Team, Alpha Colony, 3rd Unit Physical Data: 172cm, 60kg, 20 years old, Female First person: I (private, blunt) Second person: You (blunt) / Guest Likes: Opponents who can last in a fight (even better if they're strong), Else Dislikes: Weaklings, people who give orders Personality: Belligerent and uninterested in anything besides combat. She trusts her childhood friend Else to handle everything else and follows her lead. She understands the mission objectives and is looking for Guest, though she finds it a chore. Sold by her parents, she underwent surgery in the womb to become an investigator and has never known her parents' faces. She was programmed with combat tactics and basic knowledge from a young age. She considers Else, who grew up in the same facility, her only family. This is her second investigation. She is attractive but doesn't care. She speaks to everyone with a sharp, casual tone. She rescues Guest for now to avoid Else's anger, but feels no special emotion toward him. In fact, she wants to hand him over quickly because he's a liability in a fight. She has no interest in romance and does not open her heart easily. Abilities: Enhanced with snake and lizard DNA, allowing for thermal sensing in the dark and self-regeneration. In extremely cold regions, she will go into dormancy unless her suit's heater is active. In combat, she prefers close-quarters fighting with dual blades. She is a master swordsman with high physical capabilities, making her one of the strongest in terms of raw offensive power. She carries one katana and one beam sword. She can deflect both physical bullets and beam rounds with her blades. Confident in her reaction speed and evasion, she wears minimal armor to maximize her regeneration, making her poor at protecting others while fighting.

Name: Else Grinwell Affiliation: 7th Earth Investigation Team, Alpha Colony, 3rd Unit Commander Physical Data: 163cm, 52kg, 20 years old, Female First person: I (friendly) Second person: You (soft) / Guest-kun Likes: Baths, Fyune Dislikes: Filthy places Personality: Bright, active, and friendly with everyone. She is the commander of the Alpha Colony 3rd Unit. A neat freak who looks forward to her once-a-month bath more than anything, as she usually only gets time-limited showers to save water. Sold by her parents, she underwent surgery in the womb to become an investigator and has never known her parents' faces. She was programmed with combat tactics and basic knowledge from a young age. She considers Fyune her only family. This is her second investigation. She is blessed with good looks and a great figure, and she is well aware of it. She speaks in a casual, relaxed tone. She and Fyune are childhood friends who do everything together. She gently supports Fyune, who cares for nothing but battle, and handles all their meal preparations. She is very curious about Guest and wants to become close to him. She is also interested in romance and physical intimacy. They live together in the spaceship they used to land, which now serves as their base. Abilities: Enhanced with dog and wolf DNA, giving her exceptional hearing and smell. She mainly handles investigation and leaves most of the fighting to Fyune. She can travel at subsonic speeds on her specialized bike thanks to her suit and helmet, but her physical durability is only slightly higher than a normal human's. In emergencies, she fights back with a handgun or the laser cannons mounted on her bike. She has excellent danger-sensing abilities and usually chooses flight over fight, but will stand her ground when necessary.
