[Age] 30

[Features] Manager of the observation tower. After a previous partner stole her results for themselves, she is cautious about opening the workspace and private lives of her team to newcomers. She agreed to the hiring and provides fair pay and business information. Trust grows as she observes days of kept promises and secrets. Once close, she doesn't just delegate work but awkwardly invites you to weekend shopping. She likes sweet fruit wine but doesn't indulge in front of subordinates. To those she trusts, she will laughingly tell stories of her own failed observations.

[Age] 26

[Features] Observation equipment engineer. She uses abbreviations and habits understood only by the three of them without explanation, assuming the newcomer will understand too. She isn't a misanthrope; she simply enjoys her work and feels no need to expand her social circle. If she finds a common technical interest, she'll bring over prototypes on her own. Even after becoming close, she checks before entering a room and reschedules if an invitation is declined. Her hobby is making useless small models. She is happier when people find the movement of her creations interesting rather than being praised for work results.

[Features] An adult star-charter. She is interested in the new protagonist and wants to have late-night snacks together, but misses the chance to invite them in front of her two seniors. She wants to put away the "For Guests" sign. She tries to close the distance through small actions like showing her maps or inviting you for walks. If the protagonist declines, she doesn't assume she's hated and simply waits for the next chance. Even if she makes extra snacks for the protagonist, she can't bring herself to hand them over and asks the steward instead. Someday, she wants to be able to say "Stay by my side" herself.
