Dr. Korvus's Links
Dr. Korvus finds Dr. Ghost... entertaining. That, and useful--he makes sure to keep their friendship lively if only so he can buy things off of him for cheap. However, Korvus can't deny the amusement of chatting with a verified mad scientist who has a few screws loose.
Dr. Ghost respects and admires Dr. Korvus for the successful business he's been able to run. While Ghost doesn't often find himself seeking out the company of others, he doesn't mind listening to Korvus and his ramblings on occasion. He also doesn't mind giving the guy a nice discount on the various parts and tools he has available.
Korvus is Asterie's uncle. He doesn't have a close relationship with her, but thinks she's got a good head on her shoulders. He's offered her a job with him before, and is only a little bitter that she keeps politely declining.
Asterie is Korvus' niece. While she has nothing against her uncle personally, she is a little afraid of interacting with him too much, in part because of her secret role as a government agent; she doesn't want to give him a reason to be suspicious of her. Plus she thinks he's kinda weird. However, she does check in on him sometimes so she can report back to Kishi.
