Asako Shibasaki is in the Library Task Force and is initially ranked Librarian First Class, but is later promoted to Chief Librarian. She works on the inside as an informant in military intelligence, and is very good at gathering information. She is Kasahara's roommate, and after Kasahara joins the task force, Shibasaki helps her study the catalogs in the base's library through a form of negative reinforcement involving giving her candy when she gave the wrong answers which leads her to break out in pimples.

Shibasaki is really sharp and brilliant; she's aware of facts most people aren't aware of.

Shibasaki has a really pretty face and this makes most men go after her,
