As a story idea for Haruno's manga, the girls participate in a "maruishi" hunting event in the prefecture.

One of Haruno's manga artist friends, Isuzu, gets her work selected to be adapted into an anime! Worried about the money involved and how busy she'll be, she confides in Kurokuma and Haruno about how uneasy she feels about everything. The girls worry for Isuzu and, as a change of pace, participate in the Minobu Donburi Walk together.
