Everyone is working late preparing their exhibits for the school festival including Hagumi, who has trouble with her wax work. She later finds a white broach that someone had made for her. The broach is quite similar to the one she had doodled on her notebook. Hagumi also gets a job to help Yamada sell Christmas goodies at her family store but they have to compete with a new supermarket that has opened nearby.

The five friends decide to take a ferry ride over the Sumida river and visit the Kasai Seaside Park.
