Hakkeyoi, Dancing School Festival

Kirika has arrived at the festival and is searching for Karin. On the other hand, Karin has switched her outfit with Himeka's sumo outfit and must run from Kirika so as not to embarrass herself. As she runs, Kazune helps her by letting her wear his outfit and in the end, Karin dances with her "prince". During the dance, Kirika takes her ring without her knowing.
