マリア様がみてる～3rd～

Summer break sends Yumi Fukuzawa to the Ogasawara family's vacation house with Sachiko Ogasawara, the older student whose petite soeur she became in the Yamayuri Council at Lillian Girls' Academy. The quiet does not last: old acquaintances of Sachiko's arrive, wealthy girls who ask out loud whether Yumi belongs at her side. This five-part OVA series is the third entry, after the two television seasons.
