She meets a Deaf woman, Marie Nakazawa, a childhood friend of an older member of the Task Force, Mikihisa Komaki, who is advising Marie on books she should read. Iku senses that Marie is in love with Komaki. Meanwhile, the librarian Asako Shibasaki is meeting frequently with a curator who has introduced himself as Shuji Asahina. Hikaru Tezuka, also of the Task Force, is fond of Asako, and is not sure what to think about all this.
Now Komaki is arrested by the Betterment Squad. A book he recommended to Marie had not been approved. Komaki is taken away, leaving the other members of the Task Force enraged at his detention on these dubious grounds.
To make matters even worse, Iku’s parents show up. They were strongly opposed to her joining Library Defense, and now her secret—the fact that much of her job involves armed combat—is revealed.
Will Komaki and Marie be torn apart? What fateful decision will Dojo make as confusion engulfs his unit? And how will Iku get through this?
