Shigure seems depressed, so the cats try to figure out what's causing her to feel down. They guess that it could be lack of access to her brother, so the cats set up some alone time for Shigure and Kashou.

Cacao visits her human friend Chiyo's house to have a sleepover. Chocola and Vanilla are having a mild panic from being apart from Cacao, and Cacao experiences a new sensation by spending time outside.
