The ratings are in for Fuwa-chan & Hazuki vs Hina & Saya Kamitani:
The episode drew 5.8% individual and 9.5% household in the Kanto region, ranking 8th in the "Other Entertainment" category for the week.
5.8% individual would be 2.51 million viewers, and higher when accounting for the rest of Japan because the Kanto region only accounts for 1/3rd of the population.
