Haruna and Momo service dominates as the latest OVA covers chapters 54 and 55 of the manga.
Overall, this was a pretty nice OVA, with the production values remaining around the same area that the 2nd season was in, if not a little better.
As far as I can tell, no release date has been announced for a 10th OVA. But if tradition holds, it will probably release with the 19th tankobon in perhaps 4-5 months.
