The office is featured in the 8th Light Novel where Kazari calls Kuroko on a recent robbery of a luggage bag. Here, Kazari discovers that the luggage bag had an invitation slip with it, that is addressed to a subsidiary of Tokiwadai Middle School, as so she called Kuroko to make it clear on the involvement of Tokiwadai in the case; Kuroko however, tells her that she has never heard of such a place in Tokiwadai. Kuroko later leaves in pursuit of the robbers instead of the victim, whom the bag was supposedly stolen from.
