On this episode, Haruka brings Matoi and her group to the beach near a shrine. Later, Matoi learns about her mother's connections.
The beach fan service is decent and it's funny to see the girls how they react to certain moments. Also Hideo joining in randomly is somewhat strange but I guess they need a pervert-like character at the beach anyway. Other than that, seeing Matoi learning about her mother's connections is not bad. Now what's going to be the plot or development for Matoi? Overall, decent beach fan service and more main plot development.
Conclusion: Decent beach fan service and more main plot development.
