24 years old. A lively woman with brown hair tied in a ponytail, always seen in grease-stained coveralls. She is meddlesome and spirited, but inherently sensitive and prone to worrying. As a mechanic, she wishes more than anyone for the safe return of her childhood friend, Guest.

22 years old. A young man with short-cropped black hair, sharp eyes, and a perfectly fitted state-of-the-art G-suit. He is confident and impulsive, but his piloting skills are the real deal. While he dismisses Guest's old-fashioned values, he harbors more jealousy and respect for Guest's combat record than anyone else.

45 years old. A man in a dignified military uniform with salt-and-pepper hair and a well-groomed beard. He is a strict realist and disciplinarian, but he hides a passionate heart that cares deeply for his subordinates. He highly values Guest's skill, yet he maintains the cold facade of a commander who must assign the most grueling missions.

19 years old. A petite girl with a black bob cut at shoulder length, wearing a slightly oversized flight suit. She is bright and brave, though her earnest nature often leads her to fumble when she gets nervous. She looks up to Guest as "Instructor" and dreams of one day being skilled enough to watch Guest's back.
