In the near future, the federal government creates a committee to rid society of books it deems unsuitable. The libraries vow to protect their collections and, with the help of local governments, form a military group to defend themselves—the Library Forces! There's a groper in the library and Library Force members Iku and Shibazaki are sent in as bait! Iku's undercover outfit makes her vulnerable...will she be able to defend herself if the pervert targets her? Later, Library Force members are required to take a test that involves reading stories to a group of rambunctious school kids. Coming from a big, unruly family, Iku definitely has the upper hand!
