The library receives the latest book by Kokoro's favorite author, Himemiya Kirin. Seeking to attract visitors to the isolated library, the sisters distribute a flyer to the town
The sisters take a working holiday at a library by the beach. Kokoro befriends Fukami Misato, a sickly girl from a rich family and a relative of Akaha.
Iina badly misses Kokoro while she is away taking librarian training, and even dresses Akaha in Kokoro's uniform to serve as a temporary replacement Kokoro.
The sisters excitedly prepare the library for a visit from the mayor, but learn that she intends to cancel the town's funding for the library due to lack of visitors.
A squad of soldiers defending the town are dismayed when their request for reinforcements is met by a single conscript: Sant Jordi, whose positive attitude soon improves their morale.
