Upon reading her father's written account of why Kokoro Library was built, Kokoro firmly resolves to continue running Kokoro Library alongside Aruto and Iina for as long as she can even though she tells Akaha that she can be a librarian pretty much anywhere. Kokoro bursts into tears, the Funny Turtle Thief explains that crying her eyes out will not solve anything and to reflect upon the sentiments that she has felt during her prologue as a librarian for clues as to what has to be done. Kokoro decides to share her father's prologue behind Kokoro Library as she sets course for the city only to find that her sisters feel the same way and that the logistics of the journey are easier said than done. Iina's car malfunctioning, Jun's car exhausting its fuel supply, and Kokoro's motorcyclist friends being stopped in their tracks by a landslide . . . the Funny Turtle Thief becomes the key to a vital journey to Mayor Marie Momochi who explains that the people have made it crystal clear that it will cost her her seat as mayor if she insists on closing Kokoro Library. In the months ahead, Kokoro Library develops a home delivery/retrieval service for its library books.
