On this episode, Arima sent a guardian to investigate to investigate a city. Later, Rokuro and his group investigates an elementary school.
It's nice to see another new important character introduced and Rokuro's and Benio's relationship getting stronger (even though they didn't realize yet). Also the demon action was pretty cool and better than some of the previous ones. Other than that, they revealed a mysterious person who is most likely one of the antagonists. Now what's going to be the next demonic plot? Overall, a cool new character introduced and some more demon fighting action.
Conclusion: A cool new character introduced and some more demon fighting action.
