I'm a librarian who loves anime, manga, and reading a wide variety of genres.
During the scene with Pei, it occurred to me that this book feels like lots and lots of fanservice (in the general sense, not the specific sexytimes sense). You know, the kind of stuff that fans of Firefly, Farscape, Cowboy Bebop, etc. might like to see their favorite characters doing, just because they love them. Except not quite, because it's also trying to serve as an introduction to all of these characters.
