This is the OVA for the second season of Sekirei. Sekirei Diagnosis day. They're talking about what happened at the bridge, and some things further in show it's not after the end of the season. Maybe around the middle. "It could only belong to someone, on the itty bitty titty committee." The OVA is just here for fanservice basically. There's a tiny bit of story, but it's mainly the girls being in competition, Seo hating his job while his Sekirei, Hibiki and Hikari are on his back about never having food or money. They end up on a day vacation, Minato and Seo are surrounded by girls in swimsuits, orjust naked in general.
